Tea & Coffee
Caffeine is a natural chemical that activates the central nervous system, which means that it revs up nerves and thought processes. Regular caffeine consumption, from coffee and/or tea, has been shown to increase short-term focus and alertness, as well as long-term memory.
Green and black teas
Green and black teas contain anti-inflammatory antioxidants that are good for preventing and managing arthritis, memory problems, and cataracts. Tea (it’s best to drink unsweetened to avoid the harmful sugar) is also helpful for keeping skin healthy and hydrated. On the other hand, regular green and black teas contain caffeine, which can exacerbate IBS or insomnia, and they also contain tannins, a common trigger for migraine headaches.
Coffee has an undeserved bad reputation when it comes to its impact on health. In fact, caffeinated coffee has been shown to help prevent memory loss and decrease the risk of certain cancers. However, caffeine can exacerbate IBS and interfere with sleep, so it is best to stick to decaffeinated coffee if you’re stomach-sensitive or you suffer from insomnia. If you have high blood pressure, speak with your physician about your coffee habits. If you have high cholesterol drink filtered coffee — unfiltered coffee (like French press, espresso, and cappuccino) may increase LDL (“bad”) cholesterol.
