According to the research published in the Annals of Neurology, women who consume about two servings of strawberries or a single serving of blueberries tend to experience less decline in their mental health over the years when compared to others. These berries are known as the powerhouses of nutrition for a reason. The data has been collected after studying more than 16000 different females over the age of 70. Those who had the highest intake of berries managed to postpone the decline of their cognitive abilities for more than two years in total. The effect was said to be related to the anthocyanidins that are contained in these berry fruit examples.
