Tea consumption linked to cognitive health and longevity

Research indicates that tea, particularly varieties derived from the Camellia sinensis plant such as green, black, white, and oolong, offers significant health benefits. These benefits include protecting blood vessels, reducing inflammation, promoting relaxation, and potentially improving gut microbiota.

Green tea is specifically noted for its cognitive advantages. It contains caffeine, which provides a mild stimulus for focus and alertness without the anxiety often associated with coffee. Additionally, the amino acid L-theanine works alongside caffeine to support brain function. Regular consumption of at least 100 ml of green tea per day has been linked to improved mental functions, a more relaxed mental state, and a reduced risk of dementia due to its neuroprotective effects.

While herbal infusions like chamomile, mint, and ginger also provide health benefits, they typically contain different levels of polyphenols and are generally caffeine-free. Studies suggest that tea drinkers may also experience increased longevity compared to non-consumers.
