Nutritionists believe that proper diet plays a significant role in enhancing and protecting the brain, including against Alzheimer’s disease.

They are of the opinion that what is good for the heart is also good for the brain.

Jennifer McDaniel, a Registered Dietitian Nutritionist, said on Friday in Beijing that blueberries, a super food rich in antioxidants, often come as the priority choice for nutritionists to make a suggestion.

She said they can help reduce oxidative stress on the brain.

McDaniel recommended that it is ideal and healthier to eat strawberries and blueberries at least twice a week.

The dietitian said nuts and whole grains are also universally recognised by nutritionists, as the foods that help fuel the brain.

“Nuts are recommended at least five times a week and whole grains three servings per week.

McDaniel added that unsweetened cocoa has been specially proposed, because it has shown to increase activity in the brain related to memory.
