Our bodies have specific nutritional needs in terms of energy, repair and regeneration. These needs are met by different types of nutrients found in the foods we eat. Protein is needed to maintain the tissues in the body. Virtually every tissue in the body is made up of, or contains some form of protein. The body can also metabolize protein for energy in the absence of carbohydrates.
Protein is the building block of muscle tissue.
If our desire is to increase that muscle tissue, there must also be an increase in dietary consumption of protein. Carbohydrates and fats are needed by the body to provide both physical and mental energy. These nutrients, along with fiber for enhanced digestion, are best obtained through eating unrefined grains and vegetables. Vitamins and minerals, also essential to the body, are found in varying amounts and types of foods we eat. This creates a need for eating a well-rounded variety diet to ensure we fulfill the body's daily requirements.
