Ramya B, Executive Nutritionist, Cloudnine Group of Hospitals, Chennai in an interview with HT Digital talks about nutrition required by brain and all the foods one must include in their diet to improve memory and brain function.

Which is the most important age for brain development?

The first two years of life are very crucial as this is a period where rapid growth and brain development take place. The child has to be introduced to all kinds of food groups by the time when the baby turns a year old. Regular nutritious food intake to be ensured as there is a continuous demand for better cognitive function. During adolescence, the demand is even higher in order to improve sharper memory and thinking ability.

What are the nutrients that are important for my child?

– Zinc, iron, choline, iodine, folate, and vitamin B12 are the important key nutrients for cognitive function. These nutrients play a vital role in DNA, RNA synthesis, nervous system myelination and neurotransmitter functioning.

– One more important nutrient is omega-3 fatty acid. Omega-3 fatty acids is a brain nutrient that comprises 35% of the brain lipids. DHA is a type of omega-3 fatty acid which is abundantly found in neuronal tissues.

A study states that in the last stage of pregnancy and the first 18 months of life rapid accumulation of DHA takes place in the brain. Therefore, it is most important to deliver these nutrients adequately during the early childhood period. Deficiency of these micronutrients during childhood can cause detrimental effects on attention and memory.
