Caffeine stimulates our nervous system, making us more alert and focused. However, sometimes we do not take into account the pros and cons of drinking coffee.
A regular cup of coffee –filtered, espresso or instant coffee– contains something like 75mg to 100mg of caffeine. After drinking coffee, caffeine is absorbed in your stomach and intestines and goes into the bloodstream. The stimulating effect of caffeine is associated with A1 and A2A adenosine receptors in your brain.
The effects of caffeine can last many hours depending on how fast it is metabolized and broken down in the liver and flushed out via urine.
People with high sensitivity to caffeine have a slow metabolism in the liver and high binding in the central nervous system –this means that even small amounts of caffeine will have a stimulating effect, and higher doses can lead o sleep issues.
People who have a regular sensitivity to caffeine can drink anywhere between 2 and 5 cups of coffee a day without any adverse reactions.
And those with low sensitivity to caffeine metabolize the substance quickly in the liver and are not affected by coffee.
So how do you balance the potentially negative effects of caffeine and the potentially positive effects of polyphenols?
Coffee contains caffeine, which is currently widely used in energy drinks and many painkillers, since caffeine seems to enhance the action of painkillers such as paracetamol and ibuprofen.
Well, to get the most polyphenols out of your coffee, opt for the lighter roasts, sometimes labelled grades 1-2, and to keep your caffeine levels safe, don't drink more than a couple of cups of caffeinated coffee daily.
Like many other drinks, coffee has its pros and cons. You can drink coffee as long as you avoid excesses. You can vary your breakfast drinks so that your body and mind do not get used to the extra energy that coffee brings. This is a simple tip to make you feel healthy.
