More and more scientific evidence is emerging to show that some of the foods we already eat daily could be vital for helping us to stay brain healthy into old age. Researchers have identified naturally occurring plant chemicals found in berries, tea and cocoa that could have a significant impact in reducing the brain decline with age. This study investigates a group of plant-based nutrients called flavonoids.
Flavonoids are naturally occurring phytochemicals that can be found in a large range of fruits, vegetables and drinks. Flavonoids have been known to provide antioxidant and anti-inflammatory effects but recent literature suggests, may also aid in the healthier aging of the brain. As we grow older, the spontaneous functioning of memory, attention and information processing speed may enter a gradual decline.
While we generally accept this as a normal part of aging, scientists have long been trying to find lifestyle patterns that could help us prevent it. The role of diet has come into one of the most intensively researched, showing certain foods to have a potential to benefit the future of long-term brain health. Fruits that contain a high amount of antioxidants such as berries including blueberries strawberries blackberries and raspberries are a natural source of flavonoids.
Flavonoids are thought to decrease the level of oxidative stress which can over a period of time causes the degradation of the brain cells. By minimizing this process it may This way maintain a healthier neuron and Bender 1997.
Tea is also a very significant source of these healthy plant-based chemicals, with green and black tea containing flavonoids and other natural antioxidants thought to help enhance brain function. Research indicates that drinking tea more frequently may help increase concentration and mental alertness, as well as aid healthy blood flow through the brain and nurture the cells involved in memory and decision processes. The area which has received the most scientific attention is the effects of consumption of cocoa, In particular in dark chocolate which contains a high cocoa content.
Cocoa is high in flavanols, a subclass of flavonoids which have been related to enhancement of blood flow to the brain and blood vessel function. This equates with increased circulation, Because of this providing enough oxygen and nutrients to all brain tissue Because of this helping to promote healthy cognitive function throughout the lifespan.
Experts point out that these foods are not miracle foods, nor an alternative to treatment. Rather, they should be seen as the boost of a healthy lifestyle that also involves getting enough sleep, relaxation and excercise. If combined, they can contribute to keeping healthy.
What has excited for this line of research is that it demonstrates easy additions to your diet that are manageable for a wide audience. Who in their daily routine cannot add a handful of berries to their morning meal, drink a cup of tea at work, or allow themselves a modest piece of dark chocolate periodically and still improve their longevity?
