Blueberries Help Prevent Memory Loss:
The key to preventing memory lapses is fresh fruit!  Eating blueberries increases recall in people who are more likely to develop dementia, according to a study published in the journal Nutrients. The findings suggest that ½ cup of blueberries daily lowers risk of memory loss, due to anthocyanidins and procyanidins — two powerful plant compounds that boost brain cell signaling and curb inflammation that can lead to memory impairments.

Eat Fruit – Be Happy!
Recent finding: People who ate fruit most often scored highest for mental well-being and had the lowest scores for depression. On the other hand, the more frequently people ate savory snacks such as chips, which are low in nutrients, the more likely there were to report lower mental well-being and frequent "everyday mental lapses" such as forgetting why they walked into a room, where they had just left an object or trying to remember the name of someone. Note: the benefit was specific to frequency of eating fruit, not quantity of fruit eaten --- and to fruits, not vegetables.  Reason: Nutrients in vegetables, which also are known to benefit mood and cognition, often are lost during cooking…and most vegetables are eaten cooked; whereas fruits, usually are eaten raw.
