The health benefits of walnuts include reduction of LDL (bad) cholesterol in the body, improvement in metabolism, weight management, and control of diabetes. Other important health benefits of walnuts stem from the fact that these nuts possess anti-inflammatory properties, improve brain health, and help as a mood booster. They are also believed to slow down the spread of cancer.
What Are Walnuts?
Walnuts are edible seeds from the trees of Juglans genus. They are round, single-seeded fruits of the walnut tree. The fruit and seed of walnut are enclosed in a thick, inedible husk. The shell of the fruit that encloses the kernel is hard and two-halved.
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 studies have proven that the consumption of these seeds does help in promoting brain function. There are two types of walnuts; black and brown. We shall be talking about the brown walnut in detail.
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.
