Children and Vitamin Supplements

Sunday, February 21st, 2010

All children need to take multivitamins?
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.

Children and vitamin supplements
Surprisingly, however, were more likely than children who did not need much to consume these supplements, for example, white children from families with higher incomes, more food security, better nutrition and more levels of activity. The 47 percent of those children (who were also less likely to be obese) were taking vitamins, compared with 28 percent of those in disadvantaged situations.

The team found that the cost seems to be the biggest obstacle for lower income households to add supplements to the diet of their children. “One thing we thought was responsible for this was the possibility that parental income and education could overcome other factors,” said Shaikh.

Furthermore, in fact, the data showed that 22 percent of children living in homes located under the federal poverty level, using vitamins, compared with 43 percent of households living above the line.

The 38 percent of children living in households not using food stamps used vitamins, compared with 18 percent of the youngsters from households where there were no more government aid.

Vitamin C

Friday, January 29th, 2010


Vitamin C is an essential nutrient in higher primates and some other species also. Vitamin C is essential for some metabolic reactions of plants and animals and is created by most organisms except humans. The lack of vitamin C causes a disease called scurvy and therefore is given the name of ascorbic acid. Vitamin C is also used as an additive food.

Ascorbate, pharmacophore of vitamin C is an antioxidant that slows aging, which protects against oxidation and acts in vital enzymatic reactions.

There is no consensus on the recommended amount of vitamin C daily. Due to its antioxidant effect, people who follow a diet rich in ascorbic acid from natural sources such as vegetables and fruits, have a lower mortality, better health and have fewer chronic diseases.
Food sources of vitamin C

The foods to which you can find vitamin C are all vegetables. Some fruits red or blue are often rich in ascorbic acid.

In the culture “Western” sources of vitamin C are the most common citrus lemon, orange, grapefruit, bergamot. In addition to citrus, another source of vitamin C is the tomato.

The major vegetable sources of vitamin C worldwide are: kiwi, gooseberry, loganberry, Brussels sprouts or , rose hip, seabuckthorn, jujube, cabbage, spruce needles, fruits Baobab, chili, pepper, black currant, pepper, paprika, pepper, guava, parsley, broccoli or broccoli, lychee and among others.

Types of Vitamin C
Vitamin C is divided into natural and synthetic. Vitamins are classified into natural C sodium ascorbate and ascorbic acid. The synthetic vitamin C can be found with variations.

The synthetic vitamin C have advantages as its price since oil production is its raw material, a drawback is its limited effectiveness and side effects produced by consuming mineral elements as an alternative to vegetables.

The natural vitamin C, by contrast, is highly effective, and inexpensive and can be found in most vegetables and fruits (mainly citrus). By becoming crystals after extraction, has much lemon flavor, which can not be tolerated by people with sensitive stomachs.

Minerals and Vitamins are Important to Adolescence

Monday, January 18th, 2010

There are three minerals that are especially important in adolescence: calcium, iron and zinc. Each of them is related to a particular aspect of growth:

The calcium to the growth of bone mass. The iron with the development of blood-borne tissue (red cells) and muscle. The zinc with the development of bone and muscle mass. It also interacts with growth of hair and nails.

Calcium: recommended about 1200 mg / day. The availability is different depending on the food from which it derives most suitable food being milk and all its derivatives. Vitamin D, lactose and proteins that facilitate its absorption as fiber, caffeine and sugar make it difficult.

Iron: The RDA recommends a supplement of 2 mg / day for teen-age males during the period of maximum growth, between 10 and 17. For girls it is recommended a charge of 5mg/day after menarche. The iron is best absorbed from meat, while the source of grains, vegetables and other foods is absorbed worse.

adolescence

Zinc is directly related to protein synthesis and thus with the formation of tissues and it is especially important in adolescence. Zinc deficiency is related to skin lesions, delayed wound healing, hair loss, brittle nails and so on. The chronic deficit can cause hypogonadism (small size of reproductive organs). The GDR established a daily intake of zinc at around 12 mg / day for girls and for boys 15mg/día.

The main source of zinc are meat, fish and eggs. Also complex cereals and legumes are an important source. Fiber acts to hinder its absorption.

Recommended for adolescents, especially vitamins that one or another way related to protein synthesis, growth and development: Vitamin A, D, and Folic Acid, B12, B6, Riboflavin, Niacin, and Thiamine without recommending specific minimum or neither. The main source of all of them are fruits and vegetables.

Vitamin K in Food

Friday, January 15th, 2010

Vitamin_K

As already indicated, vitamin K is found mainly in green vegetables such as spinach or cabbage, but also appears to a lesser extent, in virtually all plants.

Vitamin K, like fat-soluble vitamin that is going to oils such as olive oil, but is largely lost, like other fat-soluble vitamins during the refining process, with the difference that in this case Contrary to what happens with vitamin E, it is added back.

In foods that contain vitamin K is relatively stable. Perfectly withstand heat treatments, although it can be degraded by photochemical oxidation. In some cases, the structure of naphthoquinone can be reduced to form hydroquinone, but this change is reversible and preserves the vitamins.

Usually it is assumed that under normal conditions, intestinal bacteria provided the vast majority of vitamin K, to 90% from that in the body. However, these figures have been revised, so it is considered that their contribution is the order of 50%, but in any case, enough to cover needs in normal situations.

Vitamin K deficiency in humans is very rare. It can occur in newborns, by the combination of three factors, low reserves, low content of human milk and limited bacterial flora. In some countries, all newborns receive a dose of 1 mg of this vitamin. In adults, you may receive a deficiency of this vitamin by the combination of a diet low in severe treatments with antibiotics.
