Vitamin C is an important mineral as it is involved in collagen formation which is required by the hair follicles for optimal growth. Even minor deficiencies of this vitamin can lead to dry, brittle hair that breaks easily. Green peas stand out as an environmentally friendly food. Agricultural research has shown that pea crops can provide the soil with important benefits. First, peas belong to a category of crops called nitrogen fixing crops. With the help of bacteria in the soil, peas and other pulse crops are able to take nitrogen gas from the air and convert it into more complex and usable forms. This process increases nitrogen available in the soil without the need for added fertilizer.
