Important Facts About ZINC

Updated on August 3, 2011

Important Facts about ZINC

Do you know that a 155-pound adult contains a quarter of a teaspoon or about 2.2 grams of zinc ? A typical American diet supplies 10 to 15 milligrams of zinc daily, but our body absorb less than a third of this. Zinc is reported deficient in the soil of thirty two states and is inadequately supplied in the modern diet.

Zinc is necessary in all metabolic functions and zinc is a part of the structure of insulin and may affect the secretion of several other body hormones.

Zinc Deficiency

Zinc deficiency in humans was first observed by Dr. A. S. Prasad in 1961. He conducted a study on twenty-year old mentally retarded Egyptian and Iranian male dwarfs who had tiny underdeveloped sex organs.. Dr. Prasad prescribed 100 milligrams of zinc zulfate to each of them daily. The dwarfs started to grow and develop normal sexual functions. According to the physician, the cereal grain diet, consisting mainly of unleavened bread is responsible for the zinc deficiency. Grains contain phytate, which blocks the absorption of zinc. Leavening the bread, raising it with yeast, destroys the phytate, allowing absorption of zinc.

The following characteristics are observed among zinc-deficient people :

· the skin may be dark from excessive pigmentation

· show stretch marks on the hips, thighs, abdomen, breasts and shoulders

· appearance of acne

· hair and nails grow poorly

· hair splits and breaks easily

· the brittle nail may exhibit white spots or opaquely white

Taking zinc strengthens the hair and deepens its color. Wounds that heal slowly may imply zinc deficiency. Zinc salt promotes healing of surgical wounds. Zinc deficiency may cause sexual difficulties. Girls may experience delayed menstruation or irregular menstrual cycle while boys may be impotent and have scanty pubic hair and small, immature sex organ.

It is observed that zinc deficiency is common among alcoholics. When the body contains adequate zinc, it reacts strongly to alcohol. The heavy drinker who can “hold his liquor” does not have so much zinc and is not as healthy as the person who “get drunk on one beer.”

Other signs of Zinc deficiency are : oily skin, hair loss, lack of appetite, apathy and lethargy.

Obtaining Zinc

Healthy people need not take zinc provided they avoid processed and frozen foods and alcohol. Up to 80% of zinc is removed in refining sugar and cereal grain. Frozen vegetables are often treated with chelating agents which remove most of the zinc. Alcohol flushes zinc and other minerals out in the urine.

A high protein diet of meat, fish , seeds and vegetables is rich in zinc. Herring and oysters, liver, mushrooms, wheat germ, onions, maple syrup and brewer’s yeast are especially abundant sources of zinc.

Zinc Toxicity

Zinc is the least toxic of the trace elements in humans but single large doses will cause vomiting and diarrhea. Excessive zinc can displace copper from tissues, temporarily provoking phsychiatric depression by raising blood copper return to normal. Too much zinc in the gut interferes with the absorption of iron.

Though zinc induces drowsiness, lengthy supplementation is not a good treatment for chronic insomnia, because it can cause copper or iron-deficiency anemia.
