Zinc, found in high protein foods such as beef, lamb, pork, peanuts and legumes, proves vital for cell growth, wound healing and your immune system. MedlinePlus notes that zinc is an important trace mineral, second only to iron in concentration in the body. Those with a higher risk of developing a zinc deficiency include infants, children, pregnant and lactating women, those with celiac disease, Crohn's disease and inflammatory bowel disease and people over 65 years old, states Linus Pauling Institute.
Male Sexual Dysfunction
In males, a zinc deficiency may cause male sexual dysfunction, which could take many forms such as delayed sexual maturation, meaning a delayed development of pubic hair and genitalia, impotence -- the inability to maintain an erection or have a lack of sexual desire and hypogonadism, a condition in which the body doesn't produce testosterone, states the Office of Dietary Supplements.
The Senses
Poor night vision and problems with your sense of taste and smell are side effects of a severe zinc deficiency. People with zinc malabsorption or zinc loss from prolonged diarrhea or major burns, rather than a dietary zinc deficiency prove more likely to have a severe deficiency, explains Linus Pauling Institute.
Immune System Issues
Slow wound healing, frequent infections and a compromised immune system can occur if you have too little zinc in your diet, explains the MedlinePlus. Vegetarians and vegans may present a higher risk for a zinc deficiency because meat remains an excellent source of zinc, while legumes, which many vegetarians and vegans use as a meat substitute, contain large amounts of phytic acid, which binds with zinc and stops your body from absorbing it properly, states the ODS.
Early Development
Delayed growth, poor motor function and diminished attention span can occur in infants born to mothers who have a zinc deficiency during pregnancy. A zinc deficiency may also cause a delay in cognitive development in young children, postulates the Linus Pauling Institute.
