Did you know that walnuts are a real power food? They have a healthy fat content of approx 50% and the calorific value of 100g walnuts is over 2,700 kJ. The content of the essential fat alpha-linolenic acid (an omega-3 fat) is especially high. We call a fat “essential” as it’s one that our bodies can’t produce naturally and therefore must come from our food. Essential fats are known to offer a whole range of anti-aging and anti-inflammatory benefits. They keep the heart healthy by helping the blood vessels be flexible, prevent arteriosclerosis and have a positive influence on cholesterol levels.
Walnuts are very rich in protein and therefore particularly valuable for vegetarians. A handful of walnuts (about 43g) provides 8g of vegetable proteins. They are also among the richest sources of antioxidants that help protect against cancer. They are rich in vitamins A, B1, B2, B3, C and E, pantothenic acid and important minerals such as zinc, potassium, magnesium, phosphorus, sulfur, iron and calcium. Walnuts also boost digestion, as they are very rich in fiber.
