11. Green Tea
Green tea has been consumed for thousands of years, and is known for its cancer-fighting properties. Many of the benefits of green tea come from a specific polyphenol known as EGCG. A recent study published in the journal Phytomedicine also suggests that green tea plays a role in benefitting memory, attention, and brain function.
12. Coffee
Coffee packs a two-for-one nutritional punch when it comes to cognition. Previous studies point to the protective effects of moderate caffeine intake on cognitive decline, and general stimulation of the central nervous system. Even more studies have previously illustrated that this is actually a dose response. In other words, the more caffeine you drink the better off you are.
