Zinc : Top Benefits To Prevent Deficiencies That Can Affect Your Health
Thursday, October 27,2016
The intake of zinc is too often inadequate, hence the need to take supplements to prevent deficiencies that can affect your health.
Zinc is a trace element, that is to say that we found only trace amounts in the body, the equivalent of approximately 2 g in total, including 65% concentrated in muscles and 20% in the bones. It is present in all cells, including adrenal gland, skin, parts of the brain, the pancreas, the membranes of the eye, prostate and semen.
It intervenes in the process of blood coagulation, in the function of the thyroid hormone, as well as in the metabolism of insulin.
The body needs very little zinc, but this contribution is essential. In our modern societies, the slight deficiency is common. while In women, teens, children and the elderly, intake often is below the daily minimum bar due to deficient diet. In pregnant women, particularly a cold, flu or other infection may reduce the zinc content in the body, which can be dangerous for the fetus. Other factors are also involved in reducing the zinc content of foods, including modern agricultural techniques, which have the effect of depleting the soil zinc and refining grains.
Like the best sources of zinc are animal products, vegetarians should also ensure an adequate intake of this trace element by consuming adequate amounts of whole grains, legumes, nuts and seeds.
Alcoholics, diabetics, people with kidney problems or disorders of the digestive absorption (Crohn’s disease, for example) are more likely to suffer from zinc deficiency. People with HIV are often deficient in zinc.
Zinc deficiency (common in developing countries) can lead to decreased immune function (frequent infections and wounds that heal poorly), delayed growth, smell disorders and taste, down male fertility, dermatitis, diarrhea, depression, weight loss, irritability, apathy.
Zinc : health benefits
Zinc plays an essential role in hundreds of the body mechanisms. activates the enzymes responsible for the formation of genetic material (DNA and RNA) and is intimately involved in cell growth. has an antioxidant action via an enzyme, superoxide dismutase, which is a constituent: it thus helps the body defend against damage due to excess free radicals.
It allows the proper functioning of the immune system by ensuring the optimum activity of T cells, Zinc is also involved in sexual maturation, reproduction and fertility, good skin and hair, and even taste and smell.
The main beneficial effects of zinc
Zinc can help the body to protect against colds, flu, conjunctivitis and other infections. In a US study conducted on 100 people at the initial stage of a cold, those suck zinc lozenges every 2 h recovered about 3 days earlier than subjects treated with placebo pellets.
Zinc lozenges also promote healing of mouth ulcers and sore throat. As a supplement, zinc could strengthen the natural defenses of the body, especially when a deficit existed. It has been tried in the treatment of more serious diseases: rheumatoid arthritis, lupus, chronic fatigue syndrome and, even, multiple sclerosis and AIDS, without that we have so far achieved significantly positive results.
Zinc to fight against infections
Zinc is bound to proteins and is concentrated in muscles (60%), bone (30%), liver (5%) and, in men, in the prostate. Its elimination is mainly by the intestinal tract, but also through sweat and flaking of the skin. As the body does not store zinc, it must be taken with food, especially foods high in protein such as meat and fish.
Constituting a very large number of enzymes, zinc plays a crucial role in cell synthesis and immune processes. Although all cells in the body may need zinc intake ,this mineral is often insufficient. Hence the importance of taking zinc supplements to prevent deficiencies that can affect your health.
Helps reduce the symptoms of colds, flu and other infections.
Reduces skin problems and certain digestive disorders.
May protect against prostate cancer.
Available sources based on zinc:
Tablets, cream, ointment, capsules, lozenges, tablets
Zinc promotes fertility
Zinc has a positive effect on the production of various hormones. It could increase male and female fertility, and plays an important role in the proper functioning of the prostate. It might also be effective in hypothyroidism and, insofar as it raises the insulin levels, help diabetics. Stimulating the healing of wounds and lesions of the skin, it is used – orally or applied topically as a cream – in the treatment of acne, burns, eczema and psoriasis.
It also improves the health of hair and scalp. In addition, it was shown that it was slowing the loss of sight in case of macular degeneration, a common cause of blindness after age 50 years. Finally, it may be useful supplement for people suffering from chronic diarrhea and malnutrition.
In nutritional supplement, zinc lozenges should always contain copper; Zinc tablets, which often contain vitamin C, are used to prevent colds and flu.
Beware, if you are taking medication, consult your doctor before taking supplements.
Your daily needs
The recommended daily allowance is 10 mg for women and 12 mg for men. It can be lowered by 20 to 30% when the diet is rich in meat products (including zinc is similar), and must be high (15 mg) in case of mainly vegetarian diet. The contribution is not exceeded was set at 15 mg for supplements, higher doses (up to 20 mg per day) are reserved for frail elderly and the specific case.
If deficit contribution
The true deficiencies are rare, but a deficiency sufficient to cause poor wound healing, increased number of colds and flu, decreased taste and smell and skin problems. It can also lead to impaired blood glucose (with higher diabetes risk) and a decrease in sperm count.
If excess intake
The prolonged intake of more than 30 to 50 mg per day clearly weakens immunity and lowers levels of good cholesterol (HDL). Beyond 30 mg daily, it may in the long run, disrupt the absorption of copper and be a source of anemia. Very excessive doses – over 200 mg per day – can cause nausea, vomiting and diarrhea.
Supplements: the recommended dose
The dose provided by the supplements varies between 10 and 15 mg per day. Taking zinc for more than one month may disrupt the assimilation of copper: in this case select supplements containing 1 mg to 15 mg of copper to zinc. Against colds and flu, suck 1 lozenge of zinc every 2 to 4 hours for 1 week, without exceeding 30 mg per day.
Take zinc 1 hour before or 2 hours after meals. If you are prescribed iron supplements for a specific medical reason, do not absorb the same time as zinc. If you are taking antibiotics, wait at least 2 hours before ingesting your supplements.
Meat, liver, poultry, fish, eggs and seafood (especially oysters) contain in high amounts. Cheese, dried beans, nuts and wheat germ are also good sources, but their zinc is less easily absorbed than meat.
The supplements come in many forms and are often associated with vitamin C. The chemical form in which it is proposed little influence. its bioavailability.
Other interesting information
According to various surveys, zinc consumption is usually between 8 and 12 mg daily. However, 5-8% of adults have lower blood levels than the threshold limit of deficiency.
In developing countries, add some zinc to food sufficient to reduce cases of diarrhea, pneumonia and malaria. Stimulating the immune system, it prevents up to 38% of episodes of diarrhea, reduce acute respiratory infections by 45% and malaria cases by 35% or more.
A recent study of nearly 1,300 men shows that zinc taken at 15 mg daily in combination with vitamin E (400 mg) appears to reduce the risk of prostate cancer.
