India, Aug. 10 -- The brain is arguably the most important organ of the body, and needs proper sustenance to function properly. That includes not just glucose, but also other macro and micronutrients.

Taking to Instagram on August 5, neurologist Dr Rahul Chawla listed five nutrients that the brain needs the most, as well as the sources of the stated nutrients.

Vitamin B12 is essential for maintaining the myelin sheath of neurons of the brain. Its deficiency can cause brain fog, neuropathy, balance issues, and even memory loss.

"If you have a B12 deficiency, add meat, liver, fish, chicken, eggs, and dairy products like paneer, curd, and milk to your diet, and take B12 supplements in the proper dosage," suggested Dr Chawla.
