Flavonoids are a group of natural substances that are found in fruits, vegetables, grains, flowers, tea and (best of all!!!) wine. They have anti-oxidative, anti-inflammatory, anti-mutagenic and anti-carcinogenic properties.
Evidence suggests that flavonoids found in fruits have the capacity to improve memory and the effects of blueberry and blackberry appear to be most pronounced in terms of short-term memory. In one study people aged between 18 and 30 were given a smoothie before doing tests of their mental acuity. Everyone’s brainpower dipped in the afternoon, but after five hours it was 15 to 20 per cent higher if the smoothie they drank had contained 200g of blueberries.
Flavonoids are thought to increase blood flow to the brain and interact with signal pathways that are crucial to brain cell survival and growth. The changes they cause may help at the vital stage where a nerve impulse is converted into a lasting memory.
But make sure you buy fresh and eat the berries quickly because the chemicals break down over time.
