  1. How much coffee is too much coffee? See, there are many factors involved, and this also varies from person to person, but we’ll consider few important details.
    The Basics of Coffee & Caffeine
    It’s paramount that you understand that when we refer to coffee, we are talking about regular, black coffee. This means NO milk, or cream, or sugar.
    A standard cup of coffee has roughly two calories, approximately 80 -100 mgs of caffeine and packs a powerful source of antioxidants that will get you covered for your daily needs whether it’s caffeinated or decaf, the benefits are the same.
    Caffeine Sensitivity And Caffeine Tolerance
    We all react very differently to the substances we consume, and coffee is no different. This is because our unique genetic makeups and the genes responsible for metabolizing caffeine do it through our livers.​ All existing variations give room to something known as caffeine sensitivity, and there are three large groups:
    Hyper-Sensitive : People in this group get reactive to small amounts of caffeine, sometimes a cup or less will cause them insomnia, accelerated heart beat, and jitters. Also worthy of note, all of the health benefits mentioned above, are not established as true for people under this category.
    Normal : The vast majority of the population lies under this group. They can usually take up to 400 mgs of caffeine daily without showing any side effects. All of the studies made about the caffeine benefits are proven right for people with normal sensitivity.​
    Hypo-Sensitivity : Roughly 1 out of 10 people are born hypo-sensitive to caffeine, which means they can take massive doses (sometimes more than 600 mgs per day) and not show any side effect at all. People in this group might not experience the same health benefits from drinking the recommended amount of coffee per day.
    After reading the above groups, can you take a guess at which one you fall under?
    On the other hand, we have caffeine tolerance, and this happens when your body slowly generates a natural resistance to the effects of caffeine, as opposed to the first time you had it. Caffeine tolerance can develop in as early as one day, or take up to four. You can also reset your caffeine tolerance level by detoxing your body completely from it — tapering off your consumption for several weeks. However, our bodies have simple detoxing protocols for all foreign substances, and they do it now and then, so you don’t have to worry about this.
    Simply put, regular coffee drinkers have a higher tolerance for caffeine. So do people with a higher metabolism rate, and women in general when compared to men, unless they are taking contraceptive pills, in which case their tolerance level is up to 33% slower than females who are not on the pill.
    Caffeine Concentration In Certain Types Of Coffee
    Remember how we stated earlier that a regular cup of black coffee has roughly 80 -100 mgs of caffeine? Well, now that you can consider yourself some sort of coffee guru, how about we go a little deeper?
    Let’s analyze the amount of caffeine found in the following 8 oz samples, measured consistently over time. After all, plain black coffee can’t be everyone’s vice:
    3 -12 mgs for decaffeinated
    27 – 173 mgs for instantaneous
    102 – 200 mgs for plain and brewed
    240 – 720 mgs for espresso
    Notice the limits? Maybe your wondering why the heck there such a broad range in the first place? Well, the caffeine molecule is a natural occurrence in around 60 different types of plants. The biological evolution of a certain plant, combined with environmental conditions, and even the brewing method used, all play a role in the amount of caffeine a sample will have. Also different types of coffee beans will have different levels of caffeine, such as:
    1.13% for Ethiopian
    1.42% for Tanzanian
    1.5% for Arabica
    2.4% for Robusta
    Safe Amounts Of Caffeine Intake
    While it would be almost impossible to set an accurate amount of caffeine that would be safe for absolutely everyone (for all the reasons stated above). According to Mayo Clinic, it looks somewhat like this:
    Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That’s roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two “energy shot” drinks. – Mayo Clinic
    Here is a consensus for most of the general population:
    400 mgs or less for healthy adults
    300 mgs or less for pregnant women
    0 mgs for children from 0 to 4 years old
    2.5 mgs or less for every kilogram of body weight for children from 4 to 12 years old
    200 mgs or less for people who suffer from arrhythmia, hypertension or type 2 diabetes
    The bottom line is : coffee has way more positive effects on our overall health than negative ones. The evidence gathered can’t be argued with and if you get yourself the time to analyze exactly how your body reacts to caffeine, and adhere to the safe amounts recommended (about 4 to 5 cups daily for adults), you will be just fine.
    Not only that, you will benefit hugely from it, in the long run, because a regular intake of caffeine WILL improve your overall quality of life.

  2. Ideally 2 cups of Coffee which would have around 200 mg of caffeine should be a good one to have on a daliy basis
    It highly depends on individuals who are addicted to caffeine and process might need more than 2 cups.
    So, the main thing is to understand too much of caffeine can cause disturbance to the body. So limit to 2 cups per day.
    Also, do not have tea or coffee post 6 pm it might hamper with your sleep. Do check on that well.

  4. As long as you can still sleep at night and don’t notice any health effects like a racing heart, you can probably drink as much as you want!
    Years ago when I slept very little working and taking college classes, I drank a coffee in the morning, 2–3 quadruple espressos during the day, and a coffee again around 6 in the evening. I was so exhausted I could still sleep. My gynecologist said the caffeine gave my breasts fibroids, and they hurt.
    That was 20 years ago. No cancer or anything like that. So I guess I got away with it.

  5. How much coffee is it healthy to drink on a daily basis?

    Up to 400 milligrams (mg) of caffeine daily gives off an impression of being ok for most sound grown-ups. That is generally how much caffeine in four cups of blended espresso, 10 jars of cola or two “energy shot” drinks. Remember that the genuine caffeine content in refreshments differs broadly, particularly among caffeinated drinks.

  6. Anything less than about 50 cups of 250 ml is safe.
    LD50 (lethal dose, 50%) of caffeine is 192 mg/kg and that of water is about half of that, 90 mg/kg. So one should worry about the toxicity of water rather than the caffeine in coffee. Experts recommend not more than 15 litres of water per day, spread throughout the day reasonably, which is about 60 cups of coffee. More than that may cause water toxicity (check hyponatremia for more info) and death. Note that the faster you consume this amount (rather than reasonably), the closer you would be to death.

  7. The answer, my friend is yours to choose. Some folks get by on 2–4 cups, others may foolishly drink 20–40. Just remember, unless you are drinking decaff, coffee is loaded with caffeine, and maybe sugar and nice cholesterol- enhancing cream…and even decaff has some caffeine in it. Eventually it will harm our body.
    Caffeine is a stimulant that is like beating on your adrenal gland with a stick and gets you wired, and if you stay too wired , too long, you will eventually crash. So, as our old Greek friend Aristotle once said, “Everything in moderation.” If you are low on energy and need a boost, try drinking some orange juice and eating nutritious meals or a protein snack instead of the caffeine drinks.
    Short Answer: Read this good medical advice from the great Mayo clinic.

A cup of coffee may be just what you need to get going in the morning.A second cup is to get out the door, and a third (OK, even a fourth) is likely if you’re especially tired.But if you frequently have half a dozen cups or more, you could be setting yourself up for some serious health complications, a new study in The American Journal of Clinical Nutrition reports.

  17. I read this in a Blog which has some valid statistics to justify it’s position and it is mentioned that 1 to 2 full cups of coffee is considered healthy, beyond that it isn’t considered as a healthy practice.
    We all know that coffee contains caffeine which is a cancer causing agent and with which we start developing the intuition that excess coffee is not at all healthy and may lead to cancer. If that is the case, half of the American employees must be having cancer with their addiction to coffee but instead they are active and healthy. Hence, my dear friends, limited intake of coffee rejuvenates you and keeps you active. So go grab a coffee and see your productivity profoundly increase and don’t forget to grab coffee today … : ¥

  23. Frankly, it’s the caffeine addiction that is the health issue, so if your concern is wanting a caffeine fix, the cup of coffee you’re drinking is as good as any. The way you describe how you make it sound like you’re not the type of person adding 7 packets of sugar, which is good. I doubt many people realize how many calories they’re drinking in everything they’re adding to their coffee.

  25. Hi
    I used to drink a cup of extremely strong coffee hourly or two hourly every week day.
    After a three or four years, I started to get a reaction from the coffee – I started trembling and I got dizzy every time I had a cup of coffee. This reaction lasted an hour or so before it would get better.
    I could not drink coffee without getting a reaction, so I had to stop drinking coffee for a few years.
    These days I can occasionally drink coffee without getting a reaction.
    I would imagine 3 cups of coffee a day will not affect you.
    Just drink your coffee in moderation, so the same thing does not happen to you.
    These days I drink tea, a lot of tea, about 8 cups a day, but I drink it extremely weak. I use the same teabag the whole day. I do not plan to get a reaction from my tea similar to that I got from coffee…

  26. Zero .
    For the majority of human existence on this planet, coffee was unavailable to most people. In fact, it is arguable that some form of tea, and not coffee, would have been available to people for a longer portion of human existence. In almost every country of the world as we approached the twenty-first century, it has been commonplace in almost every culture to have tea or some tea-like beverage as a normally-consumed hot beverage. For these reasons, it is “normal” to have at least one cup of tea, and having a cup of coffee instead is not normal .
    But that’s not what you meant, is it? You didn’t mean to ask, “ How many cups of coffee is normal a day? ”, you meant to ask “ when consuming coffee, how many cups are ordinarily consumed? ” In this context, the normative answer is one to three: it is normative to have a single cup of some form of beverage with your meals. There’s many reasons for this: having a beverage with your meals aids in digestion, having a beverage prepared from boiling water is an excellent way to consume needed fluids without the risk of water-borne pathogenic diseases, etc. Again, the number of meals that a person consumes over the course of the day varies widely from one culture to the next. The vast majority of humans over the past few thousand years has barely had enough food to consume one or two meals, let alone afford an extravagance like coffee or tea.
    But also, that’s probably not capturing the full nuance of what you meant by your question. You probably meant, “ how many cups of coffee are normally consumed by people like me ”, in which you are referring to some average or typical behavior.
    Sixty-four percent of U.S. adults report drinking at least one cup of coffee on an average day, unchanged from 2012 and remarkably similar to the figure in 1999. Additionally, coffee drinkers currently report consuming just under three cups of coffee per day, also unchanged. (from Americans’ Coffee Consumption Is Steady, Few Want to Cut Back )
    It is normal, for Americans, to drink about one cup of coffee per day , and among people who like to consume coffee or do so out of habit, it is “normal” for them to consume about three cups of coffee per day. This is “normal” behavior for about 89% of the population:
    More specifically, 26% of American adults say they drink one cup of coffee on an average day, 19% drink two, 8% drink three, and 11% drink four or more. The remaining 36% drink none. ( ibid )
    There is an average of about 80 or so milligrams of caffeine in a cup of coffee, and consuming less than 300 milligrams of caffeine a day is considered to be a “safe” amount not associated with any detriment to health.

  31. Based on the available since, it’s “safe” to consume up to 400 mg. However, this may influence your sleep, adrenal glands, etc., so in the long-term, it probably isn’t so safe.

    Caffeine is the most popular substance consumed worldwide not only because it is readily available but because of its beneficial effects on mental processing. By binding to adenosine receptors and influencing brain chemicals, it exerts its stimulant effect. In mice, caffeine administration improves recognition memory in an age- and sex-dependent manner.

  33. According to someone,
    For healthy adults with no medical issues, it is generally agreed upon that 300 mg – 400 mg of caffeine can be consumed daily without any adverse effects.¹ The research behind this number actually bases this on a person’s body weight. So if you weigh more than the average human, you can safely consume a little more but if you weigh less than the average human you should consume a little less. Our safe dose calculator above reflects this.
    This is equivalent to about:
    5.2 Shots of espresso
    Two 5 Hour Energy Shots
    1 Starbucks Venti brewed coffee
    2.5 16 fl oz Monster Energy Drinks

  34. The amount of coffee that you can drink without harm to health, for everyone is different. It depends on the metabolic rate. At 70% of Europeans there is such variant of gene CYP1A2 at which caffeine is acquired quickly. According to the recommendations of the Harvard School of Public Health, such people are safe to drink up to six cups of coffee a day.

    How much coffee is it healthy to drink on a daily basis?

    The owner of a fairly rare gene CYP1A2, in which the neutralization of caffeine in the liver is slowed, do not advise drinking more than two cups a day. You can find out the speed of metabolism of coffee by going through a genetic test.
    All this applies to natural coffee. Soluble coffee experts recommend drinking 1-2 cups, and it is better to abstain altogether. Even in expensive powder there will be only 25% of coffee, the rest – flavors, dyes, preservatives.
    Is coffee useful?
    Responds to Dmitry Nikogosov, a geneticist
    – Caffeine reduces the risk of many diseases, including cardiovascular diseases, for example, atrial fibrillation, neurodegenerative – Alzheimer’s disease and Parkinson’s disease. Contrary to popular belief, caffeine does not increase blood pressure. People who abuse alcohol, caffeine prevents the development of cirrhosis. However, the brain, when alcohol is combined with coffee, suffers much more.

  38. Here are a few UBOIs (Useless Bits Of Information) that I collected while researching my book:
    To overdose on the caffeine in coffee, you have to be seriously committed to the process. A single cup of coffee contains 100 mg of caffeine and raises caffeine blood levels up 5 or 6 mg/L. Blood levels of people who have died of caffeine overdose averaged 180 mg/L. That means they drank the equivalent of 30 cups of coffee over a short period. Please, do not ever do this.
    Coffee is radioactive ! By my calculations, each cup of coffee emits .056 μSv (microsieverts) of ionizing radiation. Not to worry though: this is a VERY tiny amount. It would take 892,857 cups of coffee in a single dose to make a difference in your blood chemistry.

    A study done at Harvard indicated that those who drank 2-4 cups of coffee per day had a 50% lower risk of suicide . Another Finnish study showed that those Finns who drank over 7 cups per day had an increased risk, so, you do the math.

  42. The tolerance levels differ from person to person. Factors that may influence the tolerance level are:

    Weight.
    Tiredness. (drinking caffeine instead of sleeping is harmful.)
    Health. (Sickness and stimulants are not a good combo.)

    In my opinion you should follow your gut when drinking coffee. A cup or so at noon might be ok, but drinking it at 2AM in order to finish that project is bound to be harmful. As a general guideline: the less you drink stimulants, the better it is for your body.

Coffee can only help you feel alert if you get enough sleep. If you have time, I would suggest not even drinking coffee- take an hour and a half nap instead. You’ll feel much more refreshed, as this is your body’s natural way of replenishing itself, instead of staving off sleep with coffee. Limited intake of coffee rejuvenates you and keeps you active.

    The amount of coffee that would be considered normal will fluctuate from person to person. The amount will be a very personal consumption habit.
    According to this report by the Mayo Clinic, there are both benefits and risks associated with coffee consumption and these will depend on the user’s ability to metabolize the caffeine in the coffee. (1)
    Everyone’s tolerance and likes will be different, of course, so what may be a normal amount of coffee for one person may be either below average or above average for another person.

  53. I know most of you will beg to disagree with me, but coffee is not good for our body. It may have antioxidants, but is has caffeine in it. Caffeine can trigger our adrenalin hormone for us to feel jittery, and alert. In return our body releases hormones to balance it out. This artificial cycle pushes our body into stressful state. And when we are stress, our body goes into emergency mode, and it ended up depositing fats in our body. Resulting into weight gain. Caffeine is also a great metabolism killer. Not only your metabolism will suffer, but it also affects your mental and emotional state as well.

  54. I drink 16 oz coffee most days. That’s 2 fluid cups. I assume 16 to 32 oz is the range for most coffee drinkers. Before I retired, I drank 24 to 32 ozs. Yeah, 16-32 oz. Is average.

  55. Self – Manage your intake of caffiene.
    2–3 cups a day for the average person
    4–5 cups for those on high stress jobs
    6 cups for those adrenaline junkies and poor baristas who have to taste calibration shots.
    (Read the following if you have no common sense)
    I must warn you not to take all that in one sitting however. Spread out the intake over the course of a day or risk adverse health effects.
    Also, enjoy the drink and the health benefits it gives.

  56. Coffee contains caffeine which is cancer causing agent and with which we start developing the intuition that excess coffee is not at all healthy and may lead to cancer. If that is the case, half of the American employees must be having cancer with their addiction to coffee but instead, they are active and healthy.
    Kindly notice that it is 100 gram, not miligram and this amount of caffeine is equivalent to drinking 1200 cups of coffee. The scientists also warn that if the caffein intake level is close to that number, there still possibly contains the rish of death.

  58. Assuming that you are going to drink coffee anyway, and you are doing it for the benefits of caffeine, I would say there is no need to have more than one…
    Most 8 oz cups will have around 150 mg of caffeine, and even for a big person you really shouldn’t exceed 300 mg per day (IMO). The goal is to keep your overall caffeine tolerance down so that you don’t NEED to drink more cups. Tips: switch to small espresso drinks on the weekend, don’t use preworkouts on days you drink coffee, take a break from coffee from time to time…
    If you feel the need to have another cup, after lunch or whenever, you can do a couple things. Either pour smaller 4 oz cups, or try having Americanos. If you just pour a single shot of espresso and fill the rest with hot water, you will have about half the caffeine and placebo can do the rest.

  59. There’s no clear cut answer to this, as people tolerate caffeine differently. Tobacco smokers, for example, receive much less exposure to caffeine given the same intake because they metabolize it much faster. On the other hand, other people metabolize it slower than average (sometimes due to medication) and can’t get a good night sleep if they had coffee in the morning.
    The main concern is the development of caffeinism, which is a constellation of symptoms associated with excessive intake, such as palpitations, agitation, anxiety etc.. I have not heard of long-term complications of caffeine abuse (at least in the form of coffee), not in the way alcohol abuse leads to disease, although it might aggravate preexisting conditions.

  60. I am not a health professional. From what I have heard, read and been told, up to 400 milligrams of caffeine a day should be safe for adults. However, apart from coffe or caffeine pills, you need to take things like energy drinks, chocolate, sodas and such into consideration, sice most of them also contain caffeine. The amount will vary from person to person.
    So how much should you have? Just whatever feels right for you. Maybe you have a long day ahead and need a boost? Have an energy drink. But never overdo it.

  64. Caffeine operates by binding to the adenosine receptors without activating them, stopping adenosine from activating them. Adenosine has an inhibitory effect on the central nervous system. Taking caffeine regularly will cause your body to increase the number of adenosine receptors – thus blunting its effect. If you use coffee to self-medicate or for performance enhancement, then use the minimum dose to achieve the desired effect. Note that there are decreasing returns if you use the same amount of coffee every day. For most of us, according to recent studies, the daily caffeine intake should be from 200 to 400mg in order not to cause any long-term health effects. If the daily caffeine intake is more than 600mg, which equivalent to 7 cups of coffee, there will be unforeseen effects.

    I have read from a number of sources that approximately 4 cups of coffee is safe to drink (about 400mg of caffeine). That is assuming you are not overly sensitive to caffeine. Ideally, you shouldn’t drink anything caffeinated beyond early afternoon if you’re concerned…

  77. The general rule of thumb is, depending on who you listen to and your own medical condition and metabolism from 200 to 400 mg of caffeine a day. Depending on the bean/roast/brew, that could be anywhere between 2 and 8 “cups” a day. (Not all coffees are created equal in caffeine content.)
    “Cups” is in scare quotes because different retailers offer different sizes. At one place you’ll get a 10 ounce takeaway cup as the standard(DD) at others you’ll get an actual “cup” (8 ounces). At barista joints that cuppa may be as small as five or six ounces and up to 12.
    A better measurement is that mg of caffeine per ounce or ml. In the most popular coffee retailers in America (Starbucks, 7/11, Dunkin, McD) you get a range from about 12 mg to and ounce up to 22. At the low(D) you get 120 mg of caffeine in that 10 oz takeaway cup; at the high (7/11) it’s 220.
    If you are caffeine sensitive, of course, you may want to stay well below (as low as zero) those numbers. I’ve had days when I’ve consumed five, even ten times that amount and it doesn’t bother me, and since I’m approaching seventy, it obviously hasn’t killed me.(Yeah, anecdotal evidence… I know.)

  78. The active ingredient in coffee is caffeine, the most commonly consumed psychoactive substance in the world ( 4 ).
    The caffeine content in a cup of coffee is highly variable, ranging from 50 to 400+ mg per cup.
    A small home-brewed cup of coffee could contain 50 mg, while a big 16 oz Starbucks grande can contain over 300 mg.
    As a general rule, you can assume that an average 8 ounce cup of coffee contains around 100 mg of caffeine.
    Several sources suggest that 400 mg of caffeine, or 4 cups of coffee, are safe for most healthy adults ( 3 , 5 ).
    However, many people (including myself) drink much more than that without any issues.
    Keep in mind that there are many other sources of caffeine besides coffee, including tea, soft drinks , energy drinks, chocolate and certain medications .

  79. The AHA, Mayo clinic, and many other sources recommend a maximum of 400 mg caffeine intake per day. Please note, there are a variety of factors which impact caffeine tolerance, including genetics and current consumption. In reality, there isn’t a “one size fits all”, it is very individual. For example, my wife typically doesn’t drink caffeinated beverages. If she had a cup of regular coffee, she’d be wired. I typically consume about 5-600 mg/day, and have no issues sleeping or other side effects. In my case, it was a slow ramp up over many years, and has been pretty stable for the last 10.
    If you are not feeling any side effects to your current consumption (jitters, problems sleeping, diarrhea, high blood pressure, irregular heartbeat), you could probably add an extra cup on any given day. If you do feel those side effects, cut back. Those side effects are not very pleasant, but fortunately only last as long as caffeine is in your system (about 6 hrs).

  80. coffee is beneficial to your health when taken in moderate quantity( 1–6 cup of coffee in a day can be considered harmless) It is considered high in antioxidants and also contains,vitamins, minerals and few dietary proteins.Another one of the benefits of drinking coffee is it increases circulation and can stimulate the liver.Coffee increase alertness and increase mental and physical performance in the short run.Coffee also has been shown to increase blood flow to the brain, which supports cognitive function, coffee and caffeine consumption works as an Alzheimer,s natural treatment.While there are numerous benefits of drinking coffee, there are negatives as well.Consuming too much caffeine can have an addictive side effect, leading to caffeine overdose. The danger there is it can overstimulate the body, burn out your adrenal glands and really overtax your body — and when you don’t get your caffeine “fix,” it can lead to headaches, anxiety, irritability, trouble concentrating, fatigue, digestive issues and change in appetite.Coffee contains caffeine, which is a substance that alters both mood and physiology. Caffeine in coffee has the ability to impact hormones, neurotransmitters function, nerve signaling and muscles. This is especially true if you have existing health conditions — like anxiety, heart problems or diabetes — or if you turn to coffee to help change how you feel and to disguise underlying fatigue.If you suffer from ongoing stress and trouble with nervousness, a natural anxiety remedy might be avoiding caffeine in addition to sugar and other stimulants.It’s best to consume coffee in the morning or before lunch, because if you start drinking it in the afternoon or especially in the evening, the life of caffeine in the coffee and how long it will affect your body can be around 12 hours. So if you consume it in the afternoon, it can definitely affect your sleep cycle that night. Many people who drink coffee late in the day can,t sleep, and their overall quality of sleep can be negatively impacted.

    It depends on the person and the strength of the coffee. American coffee is generally so weak, it’s safe to drink it all day if you also drink some water along with it.
    If you go for a straight espresso or ristretto, it is enough for me to drink one in the morning and one in the afternoon and still have “room for one more”. If I drink 4 espresso or kort, I start to notice irregularities in my heart rhythm. And it makes me feel very uncomfortable! ☺

  89. All of them.
    Joking aside, you don’t NEED any coffee as it provides no necessary nutrients that can’t be found elsewhere, but if you enjoy coffee, there’s nothing wrong with a few cups. We all tolerate caffeine differently; I can handle 8–10 espresso shots with ease, while a new coffee drinker gets a buzz after one or two. If you’re drinking a lot, just watch the cream and sugar if you add it, the calories can add up quickly and possibly cause weight gain if you’re having too many.
    My average day usually consists of one or two large (16oz) black cups in the morning mainly because I enjoy the flavor and have a bit of a caffeine addiction and prefer to avoid a headache later in the day. I buy really high quality beans and grind it fresh every morning before brewing and I’m satisfied with less than I’d be with a lower grade bean.
    So to answer your question, you needn’t drink any, but if you enjoy it, just have it in moderation as with everything else in life and take care not to overdo it!

  91. How much coffee is it healthy to drink on a daily basis?

    A lot of people enjoy drinking coffee because it tastes good and can give us a boost of energy. Coffee is beneficial for mental health and physical health, but some people worry about the side effects like dehydration.
    Coffee is a popular drink that has been shown to have a positive impact on health. Studies have shown that coffee drinkers have lower rates of cardiovascular disease and type 2 diabetes, and drinking coffee may help protect against Parkinson’s disease.
    Drinking coffee also improves alertness and focus which can be helpful for people who need to get more done in the morning before too much time passes. Coffee contains antioxidants which lead to an increase of energy levels.
    It is not safe to say how much coffee is the right amount for an individual to drink on a daily basis. The effects of coffee depend on the person’s tolerance, body metabolism, sleep patterns, and many other factors. Too much caffeine can cause high blood pressure, heart arrhythmia, anxiety, and insomnia. However too little caffeine can cause headaches, fatigue, and drowsiness. Those who are used to drinking coffee may not feel like they have enough energy without it.

I think anything in moderation is okay as long as you don’t have a heart condition and your doctor doesn’t see a problem with it. I usually have a cup (mug) about 12 ounces in the morning while getting ready for work. Sometimes I finish it sometimes I won’t. I fill my thermos up with the rest and take it to work with me. I may or may not have one 8 ounce cup on first break and or lunch break. One thing for sure! I will not drink caffeinated beverages past 2 pm. I don’t want to impede sleep come bed time. I’ll also throw in for good measure…I’m a little over 5’9 and weigh 134 to 136 lbs. I actually do have a heart issue but it’s small enough it’s not effected with my caffeine consumption.

  106. Coffee consumption has been linked to a reduced risk of many conditions, with the greatest effects being at around 4–5 cups per day. It appears that coffee is generally safe as long as you’re not a heavy drinker.
    A new article from Harvard School of Public Health named “Caffeinated or not, coffee linked with longer life” shows that the compounds in coffee – the powerful antioxidants – show potential health benefits, the most notable being an increased life span. Studies have shown that up to 5 cups of coffee/day (or a total of 400 ml) is associated with a reduced risk of diabetes, cardiovascular disease, and mortality. An increased quantity does not seem to offer additional health benefits.
    The study analyzing data from about half a million Britons found that coffee consumption was linked to a 14% decrease in mortality rates, during the 10-year study period. An interesting finding is that it doesn’t matter if coffee is caffeinated or not, it’s the overall composition that matters – good quality coffee, freshly grounded and well-prepared, to keep its most nutrients. In two other very large studies, drinking coffee was associated with a 20% reduced risk of death in men and a 26% decreased risk of death in women, over a period of 18-24 years.
    However, if you are pregnant or breastfeeding, have a particular condition or any concerns, you should check best with your doctor.

  108. I’m not sure I understand what you mean by “healthy to drink”. I’ll assume you’re trying to get the reported benefits of coffee while trying to avoid caffeine intoxication.
    For most healthy adults (but see cautions below), up to 400 mg of caffeine per day is considered to be safe. That’s about three or four cups of regular coffee, depending on how you brew it and what you start with.
    Studies that have looked at coffee’s various health benefits have not generally tried to determine an optimal dose, but in most of those retrospective studies, the coffee-drinking participants were consuming two to four cups daily.
    Note that some if not many of coffee’s reported benefits, other than those related to alertness, mood, and test performance, may well be unrelated to its caffeine, but rather to the anti-oxidants and other components in coffee. As such, decaffeinated coffee may offer at least some of these benefits without the concerns over caffeine’s undesirable effects.
    Also note that a small number of studies suggest that coffee made by a system that uses a paper filter may be preferred for health benefits, as opposed to that from a percolator or French press coffee maker.
    Now to the caveats. The three to four cup recommendation does not apply to people who are caffeine hypersensitive (think of side effects like
    insomnia, nervousness, restlessness, muscle tremors, irritability, stomach upset, acid reflux, and the like). Similarly, if you have high blood pressure, a rapid heart rate, or anxiety disorders or are taking prescription medications (such as, but not limited to a bronchodilator like theophylline, some antibiotics like Cipro, or even some supplements, like echinacea), you should probably check with your doctor first.
    (Note that I am not a medical doctor and my comments should not be taken as medical advice.)
    Of course, if you have other sources of caffeine in your diet (energy drinks, colas, tea, etc.) you will need to adjust your consumption of coffee accordingly.

    And in another study… researchers found that for men, those who drank more than six cups of caffeinated coffee per day reduced their risk for type 2 diabetes by more than 50 percent compared to men in the study who didn’t drink coffee.

  110. According to Mayo Clinic, you can drink up to 400 milligrams (mg) of caffeine in a day. That’s about 4 cups depending on the actual caffeine content of the drink. However, if you experience
    Headache
    Insomnia
    Nervousness
    Irritability
    Frequent urination or inability to control urination
    Fast heartbeat
    Muscle tremors
    You should cut off on your caffeine intake.

  111. Drinking one cup of coffee a day will give you caffeine to last for the whole day, as its effect lasts for a long time and could be harmful if you have digestve problems. However, drinking coffee per se is not bad, it is a powerful laxative (which can also be a con really) and can be good used on skin: http://beauty.onehowto.com/article/what-are-the-benefits-of-coffee-for-the-skin-1934.html
    All in all, if you need coffee to stay awake, tea is a good alternative, but if you are hooked on coffee, try to drink as little as possible.

  113. Everybody’s different. For some people, the caffeine is addictive. Others can drink a cup or two daily without any problems. If you think you might be susceptible to the effects of caffeine, be sure to drink coffee slowly over time rather than all at once and consider reducing your intake gradually instead of stopping cold turkey.
    If you’re sensitive to caffeine, consider switching from caffeinated coffee to decaffeinated coffee; even with your prescribed cups-a-day, decaf will make it easier for you to limit how much caffeine crosses the blood/brain barrier.
    According to multiple research and studies, four cups of coffee in a day is a safe amount. Even federal dietary guidelines suggest three to five eight-ounce cups of coffee per day (providing up to 400 milligrams of caffeine) can be a part of a healthy diet.

  114. Most “how much can a person…” type questions don’t have a set answer. Will always depend on their BMI and level of health. Not to mention, type of coffee and other fluff added to it. Healthiest is organic and black. Bulletproof coffee rather tasty with healthy ingredients. And can easily be made at home.
    Another question is, are you drinking coffee to get you thru the day? If so, consider why. Should that be a yes, perhaps backing off is needed. Your body is telling you something out of whack. Like, replacing with water, a healthy diet and/or detox are needed. A friend of mine drank many cups throughout day. Did nothing despite being high quality. I suggested B12. He got and has since cut back and has more energy. Not to say supplements are the answer.
    Like alcohol, coffee can be dehydrating. In moderation, both have potential to be healthy. You’d be surprised the variet…

  115. Legend has it that sometime in the 16 or 1700’s the king of Finland wanted to prove that coffee and tea were terrible for you once and for all. He ordered one of his subjects to drink several cups of coffee everyday and another subject to do the same with tea.
    The result?
    They both outlived the king.
    On the more scientific side – there’s nothing in coffee that can really mess you up. You’ll get a mild caffeine addiction of course if you drink 3 or 4 cups a day, but that just means you’ll have a mild headache for a week or two if you quit.

  116. Caffeine is a stimulant, and an overdose can be lethal. As for other side effects, caffeine is similar to other stimulants. If you do not regularly consume caffeine, I would avoid taking more than 2 cups in any 4 hour period.
    The median lethal dose of caffeine is anywhere between 150 and 200 milligrams per kg of body weight in a human. A cup of coffee has around 100 milligrams of caffeine.
    So, you would need around 2x your bodyweight in kilograms of cups of coffee to kill yourself. There have been no known instances of lethal caffeine overdoses from drinking coffee alone. Probably because drinking that much coffee would be impractical for even the most dedicated person.
    Now, even at lower doses, there can be severe adverse side effects, and these are probably what you’re interested in.
    Overdosing on caffeine can result in palpitations, twitching, and nervousness as well as increasing your heart rate. But since caffeine is a drug easily adapted to, its hard to determine what dosage would result in significant side effects for a given individual.
    Caffeine operates by binding to the adenosine receptors without activating them, stopping adenosine from activating them. Adenosine has an inhibitory effect on the central nervous system. Taking caffeine regularly will cause your body to increase the number of adenosine receptors – thus blunting its effect.
    As for myself? I have some form of innate resistance to stimulants including caffeine. I don’t regularly consume it, it does almost nothing for me. I can fall asleep after taking a 200mg pill.

  117. Actually, it totally depends upon the person who’s drinking.
    There are millions of people in this world with different capacities and comfort.
    Some can drink only coffee for days, some can even not sustain the smell of it while some are okay with 1 or 2 cups a day.
    So if you like the intake of caffeine whether early in the morning or at any time of the day, do go for it, with your comfort.
    Well, coming to me, I’m a big coffee addict. I grab my favorite coffee mug with strong, milk coffee in the morning and then it goes on for almost the rest of the day.
    But do note that excessive caffeine is not good for health.
    So do go for it but safely.
    Enjoy your coffee!
    Take care. 🙂

  118. Stop once you feel the effects..
    I honestly dont think coffee is the way to go.
    Herbal supplements tend to do alright.
    Yerba Mate tea is a safe one.
    The fact that you are even asking this question should tell you something.
    Coffee is a huge cultural thing and one thing I have learned is.. If everyone is doing it then its probably stupid.
    I drink some bean juice every so often. Even 48 ounces in a day every so often. My stomach hates me for it and my sleep cycle is thrown off. Im sure there are many other issues Im unaware of.
    I honestly trust illegal drugs more than I trust coffee due to the way society is all about it.
    Same with bacon.
    I do take a herbal supplement from those “Now” energy boost. They work for me. Vegas to boulder Colorado with shit sleep beforehand. No jitters or tweaking.
    If you have to ask you already know.

  119. That entirely depends on a variety of factors: age, gender, height, metabolism, etc.
    Know this, every serving of coffe contains about 400mg of caffine, that’s a lot! If you just need something warm to drink, i suggest you try green tea or other types of tea. They have much more health benefits and less caffine so you can drink more.
    Otherwise I would suggest not to exceed 2 cups, maybe 3 if you really want. However if you have high BP then i strongly advise NOT to drink any coffee at all. Try to not drink coffee with an empty stomach.

  120. The vast majority of it is safe to drink, especially if made with boiling water or in a coffee machine. This assumes that the coffee has not been deliberately adulterated and that the beans have been properly roasted. It is possible that there may be some chemical residues but since the beans are inside the cherries when on the plant then this wouldn’t ordinarily be a problem.

  121. I would say maximum one 16 oz cup but I believe in the old days they only drink 6 to 8 oz 1 cup per day. Should be knocked so my answer 628 Oz per day maximum for somebody who is an adult as long as their heart function is normal

  122. Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That’s roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two “energy shot” drinks.

  123. It’s been estimated that a fatal dose of caffeine would be delivered by about 70 cups of coffee. The playwright Honoré de Balzac was said to have a habit of up to 50 cups a day, but these presumably would have been the tiny tasse-sized cups of his day. A more realistic estimate of his consumption might be more like 15 modern cups each day. He seems to have been aware it was killing him, but carried on anyway. Along with another serious coffee drinker—Baudelaire, Balzac was a member of the Hashish Club, whose members sometimes drank coffee infused with hashish.
    Balzac died at age 50 in 1850. And he looked like a man who hadn’t slept much,

  125. I read on different websites that up to 400 milligrams of caffeine a day seems to be safe for healthy adults. That’s the equivalent of 3-5 cups of coffee. But this is may not apply to everyone based on age, weight, and health. I suggest you listen to your body to determine how much coffee to drink per day. I know for sure that it takes at least 8 cups of coffee for me to start having chest pain, eye twitching, stomach pain, and muscle spasm.

  126. Yes Definitely, If you restrict to a cup of coffee a day or maximum two cups of coffee, then coffee is considered to be good. It refreshes your nervous system. The chicory in it also gives you extra energy, makes you more active. But once you start consuming more or if you start getting addicted, then its bad. Also Please don’t consume instant coffee, You can instead choose filter coffee with 20-25% chicory to the maximum or pure coffee(without chicory) which is considered healthy.

  127. I wrote an article a while back regarding this actually. Here is an excerpt:
    “Most studies suggest that by consuming between 180-300mg (milligrams) of caffeine is not dangerous and poses no medical problem. However, exceeding that amount can start posing health issues”…
    So how much is 180 mg exactly? Let’s look at this practical example.
    1x Starbucks Tall Coffee which is 12 fl oz. has about 260 mg of caffeine.
    So, based on that, 2 cups can be too much!

  128. As per latest research, people who consume four cups of coffee per day had a decrease in premature death – compared to the 22% drop in those that drank two cups. I think It’s better to take only three cups of coffee per day to stay active. There are so many processed coffee products that certainly don’t deliver the same benefits.

  129. As a general rule, you can assume that an average 8-ounce (240-ml) cup of coffee offers around 100 mg of caffeine . Several sources suggest that 400 mg of caffeine per day — the equivalent of 4 cups (945 ml) of coffee — is safe for most healthy adults.
    Keep in mind that many other sources of caffeine exist, including tea, soft drinks, energy drinks, chocolate, and certain medications.
    Short-term symptoms of excess intake
    If you drink too much coffee over a short period, you may experience mental and physical symptoms, including:
    restlessness
    anxiety
    dizziness
    upset stomach
    irritability
    insomnia
    fast heartbeat
    tremors
    If you experience such symptoms after drinking coffee, you may be sensitive to caffeine and should consider cutting your intake or avoiding caffeine altogether.

    But you could have 2 at breakfast and miss one later. 2 cans of fizzy drink containing caffeine per day as well as the coffees.
