The latest research from the Salk Institute shows that fisetin, a chemical found in strawberries and other fruits and vegetables, can stimulate long-term memory pathways in mice. This is interesting in terms of the potential for fisetin in memory enhancement in dementia and Alzheimer's Disease. From Science Daily:
Besides strawberries, fisetin is found in tomatoes, onions, oranges, apples, peaches, grapes, kiwifruit and persimmons. While eating strawberries sounds like an enjoyable alternative to popping a pill, Maher [the lead author] cautions that it would take about 10 pounds a day to achieve a beneficial effect, which might prove too much even for the most avid strawberry lovers.
