The hormone testosterone governs several key activities within the human body. A man's fertility, muscle strength and sexual vitality are all directly linked to his testosterone levels. While most men produce adequate testosterone without any dietary or medical interventions, some choose to eat a specialized diet designed to promote the production of this important hormone. Few scientific evaluations have conclusively demonstrated that any food can boost testosterone levels in men; however, many nutritionists advise a diet rich in zinc as a natural, low-risk method of improving male hormone balance.
Red Meat
A May 1996 study published in the medical journal "Nutrition" clearly demonstrated that zinc deficiency is a common underlying cause of reduced testosterone levels in men. Red meats, such as beef, mutton and liver, are excellent sources of this important mineral and may help improve testosterone levels. However, a high-fat diet can actually impair testosterone production; excessive consumption of high-fat meats may be counterproductive.
Pumpkin Seeds
Another food rich in zinc, pumpkin seeds are traditionally used to support male reproductive health. A study published in the "Journal of Medicinal Food" in Summer 2006 showed that pumpkin seed oil can reduce prostate swelling in rats. Many naturopathic fertility experts recommend pumpkin seed oil as a treatment for low sperm count. In theory, these crunchy treats may help to enhance testosterone production.
Oysters
In March 2005, the "Sydney Morning Herald" reported that oysters and mussels contain two rare amino acids that enhance testosterone production in men. Additionally, oysters are extremely high in zinc and essential fatty acids; these nutrients can promote healthy endocrine function in men of all ages. The "Sydney Morning Herald" notes that oysters contain the highest levels of hormone-affecting amino acids in the spring.
