Zinc Deficiency By Inadequate Zinc In The Diet

symptoms of zinc deficiencyMineral is essential for strengthening the immune system. Having a diet rich in minerals is essential to maintain a good health. Zinc plays a significant role in our health. “This mineral is essential for our body to continue functioning effectively. It protects us from a large number of diseases and helps fight others that have already settled in our bodies,” says nutritionist Natalia Lauterbach, Network World Green on Sao Paulo. Zinc Deficiency by inadequate zinc in the diet

The lack of zinc in the diet is a serious problem, which according to World Health Organization, is linked to many cases of deaths, since this mineral has an important function in our immune system. The problem is more common in less developed countries, but zinc deficiency also affects the richer countries too.

According to WHO, “The minimum consumption of zinc should be seven milligrams per day for women and about nine milligrams for men. It may vary according to age. For the elderly, for example, the number rises to eight for women and eleven for men.

WHO also informs that people who do not consume sufficient amounts of zinc, are more likely to suffer from the action of infectious agents, and therefore spend more time with patients compared to those with an adequate zinc intake.

Zinc’s Role in the body

The main role of zinc in the body happens in the immune system. “Zinc is important for the synthesis of immune cells in their action as defense against viruses, bacteria and fungi,” says Natalia Lauterbach.

Zinc also protects the body by having antioxidant activity, & reducing the amount of free radicals in our body. This type of molecule, negatively affect cell function and increases the chances of developing different types of cancer.

In addition, approximately 100 different enzymes require zinc to catalyze chemical reactions that maintain efficient cellular functions. Therefore, zinc, has an important role in our immunization; it helps almost all of the body to work better.

Child Nutrition

Zinc is especially important for children. Adequate intake of this mineral is essential for small children to grow healthily. According to WHO, some of the biggest causes of infant death are diarrhoea, which still causes 18% of deaths among children worldwide, and second reason is pneumonia, these both have direct relation with the lack of zinc.

“The immune system of children is more fragile than adults, so a diet rich in zinc is essential,” says nutritionist. To get an idea of the importance of zinc in the diet of a child, one of the most widely held by the World Health Organization to reduce child deaths in poor countries is to include supplements of zinc in the diet. Since this measure was adopted in the late 1980s, the deaths from diarrhoea worldwide in children under five years fell from 4.5 million to 1.8 million in 2006.

Zinc supplements for pregnant women

According to a survey conducted by UNICEF in 2009, zinc supplements for pregnant women can prevent many complications during childbirth and also help the baby gain weight after birth, reducing the risk of infection. Therefore, it is shown that pregnant women consume daily 12 mg zinc.

Age                                        Men                        Women

1 to 3 years                             3.0 mg                    3.0 mg
4 to 8 years                             5.0 mg                    5.0 mg
9 to 13 years                            8.0 mg                    7.0 mg
14 to 50 years                           8.0 mg                   7.0 mg
> 50 years 11.0 mg                    8.0 mg

Symptoms of lack of zinc

As the zinc works in different functions of our body, lack of it has consequences, such as:

Impaired immune system, Injuries that do not heal, Lack of Taste or Smell, Skin Problems (psoriasis), Increased levels of blood glucose, Dry and yellowish skin, liver malfunction, etc.

“Among all these problems, the most worrisome are the adverse effects caused by lack of zinc in the immune system. This causes the body to become much more exposed to any infectious disease,” explains nutritionist.

Sources of zinc

A balanced diet provides the daily amounts of zinc in our body. Oysters is a good choice to treat Zinc deficiency, but other common sources may be part of our daily menu. But in some cases, only food cannot provide the body with the missing quantity of zinc. “Food is always the best option, but in some cases, with the advice of a doctor, you need to invest in supplements to achieve the daily doses of this mineral,” says Natalia Lauterbach.

“A diet with nuts, like walnuts and chestnuts, all kinds of meat, rice and bread already makes our immune system work better,” says nutritionist. Besides these foods, pumpkin seeds, oats, beans and whole milk are also good sources of this mineral.

Moreover, according to nutritionists, people suffering from lack of zinc absorption by the intestine, diabetes, eating disorders, intestinal disorders and kidney disease may need zinc supplements to compensate for the lack of absorption caused by these problems.

Food                              Weight                       Amount of zinc (mg)

Oysters                           86 g                                  38
Nuts                               100g                                 4.0
Chestnuts                      100g                                4.0
Beef                               130g                                4.0
Chicken                          180g                                 1.5
Brown rice                      40g                                   1.0
Oat bran                         94g                                   2.9
Whole milk                      240g                                1.0
Beans                             50g                                   1.15
Pumpkin seed                 20g                                   1.3
Brown bread                   80g                                   1.6

Powerful combinations

According to the U.S. Department of Agriculture, several servings of foods should be combined so that the daily quota of minerals is met. To illustrate this recommendation, we can say that a portion of beef (4 mg of zinc), two rice (2 mg), and two of milk (2 mg) per day providing a total of 8 mg of zinc, which represents consumption indicated for adolescents and adults.

Symptoms of excess zinc

Even though this mineral is essential for our bodies to consume it in excess (more than 50 milligrams a day for weeks), can be unhealthy. This happens because of the relationship with the molecules of the mineral copper in the body. explains nutritionist.

The main symptoms of excess zinc and lack of copper in the body are diarrhoea, drowsiness, lethargy, nausea and frequent vomiting. “Therefore, before taking supplements, you need to know if they are really needed and what is the recommended dose,” says the expert.

  • This is a big issue in medicine. Especially now that many people have problems with slow metabolism due to environmental illnesses. I know the consequences of zinc deficiency being a hypothyroid sufferer, and in the UK they just don’t test for it unless you ask them, zinc and copper are ignored. Then when they find you are deficient the GPs seem to ignore the fact and you are left to supplement yourself. I suspect many of today’s diseases are due to deficiencies that are not tested for and expensive pharmaceuticals just patch the problem until a further more serious symptom crops up as the underlying problem isn’t addressed. Bad medicine.
