Walnut: Nutritional Value, Health Benefits, and Uses

Walnuts are one of the most popular and healthiest tree nuts consumed around the world. Scientifically known as Juglans regia, walnuts are not only delicious but also packed with essential nutrients, making them a vital addition to a balanced diet. Known as the “brain food” because of their unique shape and high omega-3 content, walnuts have been valued for centuries for their medicinal and nutritional properties.

Nutritional Profile of Walnuts

Walnuts are rich in:

• Omega-3 fatty acids (alpha-linolenic acid)

• Protein and fiber

• Vitamins: Vitamin E, B6, and folate

• Minerals: Magnesium, phosphorus, copper, manganese, and zinc

• Antioxidants: Polyphenols and melatonin

A handful of walnuts (about 28 grams or 7–8 pieces) provides a powerful mix of nutrients that support overall health.
