Walnuts are edible seeds from the trees of the Juglans genus. They are round, single-seeded fruits of the walnut tree. The fruit and the seed of the walnut are enclosed in a thick, inedible husk. The shell of the fruit that encloses the kernel is hard and two-halved. The seed of the walnut fruits contain significant amounts of nutrients such as proteins, EFAs (essential fatty acids), carbohydrates, vitamins, and essential minerals.
Walnuts have always been considered as ‘Brain Food’, perhaps because the surface structure of the walnut has a crinkly appearance like that of the brain. Due to this reason, they have been considered as a symbol of intelligence, leading to the belief that they actually increase one’s intellect. While this is not exactly true, recent scientific studies have proven that the consumption of walnuts does help in promoting brain function. They contain omega-3 fatty acids, which increase the activity of the brain. Omega-3 fatty acids coupled with iodine and selenium add to ensuring optimum functioning of the brain.
Along with their delicious taste, walnuts have antioxidants and proteins that help in imparting a multitude of health benefits. They are also a delicious supplement and therefore can be easily included in anyone’s diet. Walnuts are also considered as ‘Power food’, since they are believed to improve body stamina.
