Coffee in a healthy diet: To drink or not to drink? Since its discovery - around 900 AD - coffee has been the subject of an incredible number of myths. Today, the data about it continues to be updated, but it is still unclear whether coffee has more benefits or harms. There is information that this drink reduces the risk of Parkinson's and Alzheimer's diseases, protects brain cells from aging and is an inhibitor of the mTOR gene, which prolongs life. So far - only in lab animals, but who knows! At the same time, coffee speeds up heart rate, leads to pressure fluctuations, can provoke an exacerbation of gastritis, increase "bad" cholesterol (with regular use of more than 5 cups a day) and disrupt sleep, which is very important for controlling appetite and preserving youthful skin. At the same time, nutritionists believe that moderate coffee consumption does not contradict the basic principles of good nutrition, and the decision whether to drink it or not is a matter of personal choice.
