Berries may potentially reverse age-relatedcognitive decline
 
It was discovered earlier that anti-oxidant rich diets could delay or even reverse age-related cognitive decline in laboratory animals. Recently, studies have established that berries may be more than just oxygen radical neutralizers in the aging central nervous system.
 
The therapeutic effects of berries on age-related motor and cognitive decline were consistently demonstrated from exploring the cognitive ability of animals. Most of the evidence shows that the dietary compounds, polyphenols, accumulate in the brain after long-term consumption of berries. This suggests that polyphenols in berries may act directly within the brain areas that are responsible for modulating cognitive processes.
 
It has been proven that the consumption of flavonoids (a type of polyphenols) can result in the attenuation of cognitive decline over a period of 10 years. This is mainly due to the increased capacity of neurons in the brain to maintain proper functions during periods of aging.
 
Therefore, in order to reverse aging by maintaining your learning and memory, it may be as simple as including a moderate amount of berry fruits and other anti-oxidant rich food in your diet.
