Zinc is an essential mineral that is naturally present in some foods. It is involved in many critical biochemical functions throughout the body. A man's prostate gland requires some of the highest levels of zinc in the body, and adequate intake and absorption of the mineral is important to maintain prostate health. Unfortunately, many men do not get sufficient levels of zinc in their diet, and this may contribute to a number of health problems.
Zinc and the Body
Zinc levels affect a wide range of processes in the body, and especially in the prostate gland. Zinc is needed to help maintain a healthy immune system, and it plays a part in cell growth and wound healing. It helps in the maintenance and repair of cellular DNA and protects cells against free radical damage. Zinc is also essential to the healthy functioning of the male reproductive system, and adequate intake is especially important for men.
The Prostate
The prostate is a male reproductive organ that accumulates and uses more zinc than any other organ in the body. A zinc deficiency, thus, may seriously disrupt prostate functioning. The gland stores and secretes fluid that goes into semen and enhances the movement of the sperm in it. Prostatic fluid may also serve to enhance fertility. In addition, the muscle fibers surrounding the prostate gland provide assistance to the processes of urination and ejaculation.
Zinc Deficiency
Zinc deficiency is characterized by poor appetite, weight loss, delayed wound healing, problems with the senses of taste and smell, and frequent infections. In more severe cases, the deficiency causes hair loss, diarrhea, eye and skin problems, and mental lethargy. A zinc deficiency may also impair the body's ability to protect DNA, and may lead to cellular damage. In males, it may contribute to the development of infertility, impotence and an enlarged prostate
Zinc in Food
Although a person only needs a small amount of zinc to ensure prostate health, sufficient daily intake is required because the body has no system for zinc storage. Foods high in protein are usually high in zinc as well. Oysters contain some of the highest levels of zinc per serving, but for most people in the United States, red meat is the main source. Other zinc-rich foods are shellfish, fortified breakfast cereals, nuts and seeds.
Zinc Supplement Warning
Supplementation might be appropriate for men who may be at risk of zinc deficiency. However, too much zinc can be toxic. The March 16, 2006 issue of Harvard Medical School's newsletter reported that researchers found an increased risk for prostate cancer in men taking zinc in large daily doses or for extended periods of time. Before beginning a program of ongoing supplementation, consult a health-care practitioner to assess zinc and health status.
