Coffee is one of the most popular drinks in the world, second only to tea. It has an enormous influence on society and culture, whether it be through conversations at your local coffee shop or business meetings that can’t begin until everyone’s had their daily cup. We all “need” our morning coffee fix to function properly, but what does coffee really do to us?
Black coffee can help you burn fat .
Coffee can help you burn fat because it contains the compound cafestol palmitate . Cafestol can increase levels of cholecystokinin (CCK), a gut hormone that stimulates the release of bile, which is required for breaking down dietary fat. The presence of this compound means that black coffee will make you feel full, which will help reduce your calorie intake.
In addition, caffeine can increase the rate of fat oxidation by as much as 5%, and it can also help you exercise harder for longer periods of time without burning muscle as fuel. The caffeine in coffee has been shown to improve long-term memory recall in tests where participants memorized word lists.
Lastly, the caffeine in coffee will prevent you from feeling sluggish or tired. This can help improve your mood and reduce anxiety levels before exercising – just don’t forget that caffeine is a diuretic , so drink some water after your workout to avoid dehydration!
Coffee can help you live longer .
Drinking coffee can reduce your risk of developing type 2 diabetes, Parkinson’s disease, liver cirrhosis, and prostate cancer . Coffee also contains the compound theophylline, which relaxes blood vessels – this means that drinking coffee can increase blood flow to the brain.
People who drink 3-5 cups of coffee per day have a 20% lower risk of developing dementia, and coffee drinkers have a 50% lower chance of getting Alzheimer’s disease . Drinking 4 cups per day has been shown to reduce the risk of suicide by half!
Compounds in coffee can also protect against liver damage , regulate insulin levels, prevent gallstones , strengthen bones, improve athletic performance , aid weight loss, and reduce your risk of developing type 2 diabetes.
You should stick to drinking filtered coffee as opposed to espresso, as unfiltered coffee has been linked with higher cholesterol .
Coffee can also protect against certain types of cancer – be sure to drink it black, or with a dash of non-dairy milk and/or sweetener if you like.
Caffeine improves alertness, mood, and motivation .
Caffeine has been shown to have positive effects on the following aspects of cognition:
Mood. Caffeine can increase your arousal levels, so if you drink coffee in the morning then you’ll feel more awake and motivated throughout the day. It can also improve your mood because it stimulates your central nervous system.
Memory recall. If you’re studying, then drinking coffee before you read your notes can help you learn faster and remember more of the material later on. This is because caffeine blocks adenosine receptors – this means that your brain won’t slow down or feel tired whilst processing information.
Cognitive function . Caffeine has been shown to boost overall performance on long-term memory recall tasks, complex calculations, and reading comprehension tests.
Stamina . Caffeine can reduce your perception of effort when exercising, which means you can work out harder for longer periods of time without feeling tired! This is because it stimulates the release of epinephrine from the adrenal glands – this hormone triggers the breakdown of fat cells, which can be used as a source of energy.
Caffeine is good for your heart .
Drinking fewer than 5 cups per day has been linked with a lowered risk of death from cardiovascular disease – this may be because coffee contains the antioxidants chlorogenic acid and rutin, which reduce blood pressure and improve your heart’s blood flow.
Caffeine increases the contraction of blood vessels, which leads to improved blood flow throughout the body and thus helps reduce strain on the heart as well as other muscles during exercise . Coffee also contains antioxidants such as kahweol and cafestol, which can prevent or repair oxidative damage to your cells.
Coffee can improve athletic performance .
A study has shown that drinking coffee 1 hour before you do intense exercise such as running or weightlifting can increase your physical endurance and make the workout feel easier. This is because caffeine boosts epinephrine levels – this hormone breaks down fat cells, which provides an alternative source of energy to the muscles during exercise.
Caffeine can either heal or trigger headaches .
If you have a headache triggered by caffeine withdrawal , then drinking coffee can relieve the pain. Coffee also stimulates the production of endorphins, which block pain signals in the brain and provide a kind of natural pain relief . However, if your headaches are caused by an excessive intake of caffeine, then cutting out coffee will stop them from happening.
How much coffee should you take?
If you’re a healthy adult who does not have any pre-existing health conditions, then drinking up to 400mg of caffeine per day (the equivalent of 5 cups) is safe. There are no official guidelines on the amount of coffee that children should drink – however, it would be best to avoid giving them caffeinated beverages entirely because too much caffeine can be harmful to their developing neurology.
