Zinc also promotes wound healing and strengthens the body’s defenses, and although it may help prevent colds, a recent study found that taking zinc within 24 hours of the onset of cold symptoms, speed recovery by reducing the severity and duration of the disease predominantly winter.

Although not yet determined the dose to be administered zinc to promote healing of a cold, we can use this information to increase the intake of this trace element in the diet and thereby prevent and successfully meet one of the most common infectious diseases population.

Zinc can be obtained from foods of animal origin, especially beef, pork and lamb, seafood and peanuts, peanut butter and legumes.

You know, to recover from a cold is not only a tea with honey and lemon will help, but zinc intake through diet can alleviate the symptoms and duration of the disease.

Many healthy children and teens may be taking vitamin and mineral supplements do not need, say researchers in the February issue of Archives of Pediatric & Adolescent Medicine.

Experts indicate that supplements of vitamins and minerals are not considered necessary if it is a balanced diet. Children who really need these supplements are those that have not as good nutrition, are less active and come from low-income households, and thus might not be receiving the doses of vitamins and minerals they need, experts say.

The American Academy of Pediatrics recommends vitamin supplements for most children older than one year, but for those with chronic diseases, eating disorders, and certain other conditions.

Overdose or poisoning by the use of supplements can be a problem, especially among younger children (2 to 4 years). An overdose can cause vomiting or more serious problems such as kidney or liver damage.

Dr. Ulfat Shaikh, study author and assistant professor of pediatrics at the Davis medical school at the University of California and a pediatrician at Children’s Hospital at UC Davis, said: “We were curious to know why some parents might choose counter multivitamins for children and others not. He explained that the study hypothesis was based on that supplements can be used to reduce adverse effects, if parents think the child is not eating well or are wondering where their next meal would come.

The authors reviewed data on vitamin and mineral supplements, as well as diet, exercise and health insurance factors of about 11,000 children and adolescents between 2 and 17 years of national survey examining the health and nutrition.

Nearly one third (34 percent) of the adolescents had used supplements of vitamins and minerals during the month preceding the interview. As expected, children who were overweight were the ones taking vitamins and minerals.

Vitamin A and precursors thereof, such as the famous carotenoids, always resurfacing in the summer when all those associated with skin care under the sun. However, the vitamin also protects us from the cold and therefore it is essential to include it in these months.

Not only strengthen the body’s defenses, helping to prevent colds and other diseases typical for this time of year, but also vitamin A retain the health of our skin, preventing dryness of the same and the mucous membranes to cold .

Vitamin A can be included easily by using carrots, squash or steamed spinach as well as we can get it from orange fruits, tomatoes, liver and egg yolk.

As we can see, vitamin A is not only an ally for our health and beauty of the skin in summer, but in colder months is as important as the famous vitamin C.

In addition, many minerals are lost in sweat and need to be replenished daily, as well as some vitamins and minerals have antioxidant to counteract oxidative stress produced by physical exertion, for all these reasons, if you’re an athlete, do not forget the vitamins and minerals.

Calcium, potassium, magnesium and sodium are essential to prevent electrolyte imbalance, and also help the muscle contraction required for each movement.

Vitamins A, C and E meet antioxidant, while the B complex collaborate in the proper production of energy from macronutrients and allow the nervous system to function properly.

Without the vitamins and minerals intake of fats, proteins and carbohydrates is not much, so do not forget to include these micronutrients in our diet every day if we get a successful training and a great sports performance.

In a panel discussion held in Washington, nutrition professionals, biochemists, toxicologists, physicians, geriatricians and oncologists indicated that there is no doubt that they are necessary and even indispensable.

However, no study has shown that the amount is equivalent to quality and no matter how many vitamins a person takes will not get to live more or better health.

In fact, experts say, the recipe is to eat healthily and do more exercise.

“Half of Americans are taking multivitamins and minerals and the fact is we do not know how it is good,” said Michael McGinnis, an expert of the Institute of Medicine, an organization that advises government on health issues.
Consume vitamins in excess may be useless and dangerous

Rather, he said, “We are concerned that some people are consuming too much of certain nutrients.”

Experts say studies are needed to identify the vitamins that are not in their diet and what supplements are, in fact they provide any health benefits.

Scientists report that high levels of some vitamins can be dangerous, while others are excreted through urine.

Among the hazardous include iron and vitamin A (beta carotene), according to a study, may increase susceptibility to lung cancer in some smokers.

In addition, many foods are fortified with vitamins and minerals and therefore the value of vitamin supplements is questioned.

According to experts, until now there have been no studies which demonstrate that increased intake of vitamins and mineral supplements help prevent chronic diseases such as cancer or heart.

The only thing that is clear, they add, is that people who care about the vitamins and mineral supplements for their health care and so do with a healthy diet and exercise

As always, food will play an essential role. In this case we will help strengthen the liver and improve its status, namely the hepatocytes, which are responsible for the proper functioning of this body. To make this function correctly the liver needs input from a number of specific vitamins such as B1 or thiamine, B6 or pyridoxine, and B 12 or cyanocobalamin.

Getting these nutrients is essential for the liver to function properly and fulfill its purifying function. Above all we must emphasize on providing a good dose of these nutrients when they have been poisoned by alcohol or are taking medications that purifies the body through the liver. In these cases the damage and wear is greater, so that we give our body of these groups extra dose of vitamins. In more extreme cases will require the use of vitamin supplements in any case we must prescribe a doctor.

To achieve this requires that we incorporate in our diet foods rich in these vitamins. To get the vitamin B1 we have whole grains, soy, beans or pork, among others. For vitamin B6 should draw on foods such as wheat germ or brewer’s yeast, two supplements it is important that we add to our diet to get this vitamin, also found in whole grains, and legumes in the nuts. This type of vitamins is also present to a lesser extent in fruits such as bananas, avocados, green vegetables …

When we get vitamin B12 eating foods such as eggs, dairy, meat and fish. In the plants we found in the fermented soy derivatives. In the other plants just shows this vitamin. It is therefore necessary that we conduct a variety of foods in which we introduce these foods also will serve as a great help to other body organs.

According to research published in the American Journal of Clinical Nutrition found that meat contains one of the highest levels of the vitamin, but it is absorbed by the body when consumed.

Researchers at the University of Oslo and the University of Bergen, Norway, has found higher levels of bioavailable Vitamin B12 is found in milk, which despite having lower concentrations than the flesh is much better understood.

About 55 percent of the vitamin contained in the milk directly into the bloodstream and the fish would be the second highest source, along with vitamin A, followed by other dairy products.

In the flesh of vitamin B12 may be closely linked to proteins and this link must be broken down by stomach acid before the body can use, so in the case of older people are acid levels low and find it much harder to get the V-B12 of certain foods, having to choose dairy products, because the vitamin benefits their brains avoiding memory loss and diseases related to dementia.

For lacto-ovo-vegetarians do not have major problems that is present in dairy products and eggs, so do not suffer the same shortcomings, but a problem in other forms of strict vegetarianism, where these products not consumed.

So in place of meat as a source of production, vitamin B12 is found in milk, cheese, eggs, fortified yeast extracts, fortified cereals and fortified soy products.

A natural source that still carries its content is controversial, the freshwater algae called Spirulina, which according to studies would be very rich in this vitamin and a source of vegetable origin.
