Walnuts are the best nuts for a healthy heart, as they contain Omega 3 and Omega 6 fatty acids but also arginine: they all help reduce cholesterol levels in blood and protect from heart diseases.
Walnuts also contain high amounts of folic acid, which enhances cholesterol reduction as well.
They are considered a precious source of antioxidants for being rich in vitamin E, which prevents ageing, some cancers and cardiovascular diseases. The presence of an essential amino acid, arginine, is also very important, in particular for healthy arteries. Walnuts are rich in vitamins B1 and B6, which help muscles and the brain to work well, but they are also rich in minerals such as copper, zinc, phosphorus and magnesium, which is a natural anti-depressant. Being high in fibre, they help bowel transit as well.
