Growth hormones are responsible for the development of lean body tissue, bone density and an efficient metabolism. With age, the body's natural production of growth hormone decreases. This is because of physiological changes that occur with aging such as weight gain, and high sugar levels or high fatty acids levels in the blood. There are factors, however, that a person can control in order to stimulate release of growth hormone, such as proper nutrition choices.
Protein consists of the amino acids that help the body tissues to repair and grow. According to "The Healthier Life," growth hormones require the presence of all amino acids in order to perform their functions in the body. The presence of the amino acids aids the growth hormones to aid in activities such as growth, tissue repair and mobilization of fat stores. Animal sources contain high amounts of protein. Sources include meat, lean poultry and lean turkey. Another good source of protein includes seafood such as salmon, tuna and cod. Dairy products can also offer good amounts of protein and include foods like milk, natural yogurt and cottage cheese.
Eating a variety of animal and plant protein sources is favorable for a healthy, well-balanced diet. Bodybuildingforyou.com recommends supplementing animal sources of protein with soy protein is recommended. The animal proteins contain an important amino acid, lysine, which may increase bad cholesterol in the body. Soy protein, however, contains an amino acid, arginine, that may decrease bad cholesterol in the body. Soy food sources do contain good amounts of protein and can stimulate the growth hormones to increase in the body. Good examples of soy proteins include tofu, tempeh and edamame.
Carbohydrates are also important to eat in order to stimulate growth hormones. They must be eaten in good balance with proteins in the diet. Low-glycemic carbohydrates are good choices because they supply the body with a steady supply of blood sugar. This ensure that no sugar spikes or crashes occur and that the body is given a steady and satiating energy source. Low-glycemic carbohydrates include whole grains such as rolled oats, barley, whole-grain cereals and whole-grain bread. Other good sources are the fruits and vegetables groups, particularly green leafy vegetables, collard greens and broccoli.
