Peas contain a lot of protein and fibre, but are low in fat and carbohydrates. In addition, they are bursting with vitamins and important amino acids. They are like nutritional energy bullets. For example, the arginine they contain is used to release growth hormone, promote muscle growth and develop immune defence. They also contain lysine, which is important for bone health, taut connective tissue and fat burning. In addition, both amino acids increase performance and endurance. The niacin in peas lowers the cholesterol level and the risk of cardiovascular disease.
