Winter is the high incidence of children’s flu season, so how cold it away from the baby? The study found that there are four kinds of nutrients to be effective in preventing influenza.

1, food rich in vitamin A

Child scientists suggested that the lack of winter and spring VA in children susceptible to respiratory tract infection is a major incentive. The researchers of 140 cases of deaths of children the results of the study concluded that: In the cold, such as respiratory infectious diseases high season, to an increased number of children VA-rich food, will enable the child mortality rate by three quarters. U.S. scientists believe that VA is through enhanced immunity to obtain anti-infective effect. In addition, VA can reduce the risk of measles and mortality. VA-rich foods are carrots, amaranth, spinach, pumpkins, red and yellow fruits, animal liver, milk, etc., if necessary, VA oral formulations, infant 1500-3000 units per day, older children 3000-5000 units per day.

2, zinc-rich food

Studies have shown that many viruses Zinc “nemesis.” U.S. scientists used zinc inhibition of HIV have access to preliminary results, the experts zinc treatment of influenza has been made with good results.In the cold season of high incidence of multi-eat foods rich in zinc help the body to resist cold viruses, the mechanism is:

(1) Zinc can directly inhibit the proliferation of the virus;

(2) of zinc to enhance cellular immune function, especially the function of phagocytes. Meat, seafood and poultry are the richest zinc.

In addition, a variety of beans, nuts, seeds and a variety of categories is also better zinc food choices.

3, vitamin C-rich food

VC to food protein contained in Cystine reduced homocysteine, cysteine is the body’s immune — an important member of the army of the antibody synthesis of the necessary material, so VC indirectly promote antibody synthesis, enhanced immune role. VC trial abroad was 3 grams per day of oral flu prevention, but also prove to the children to eat more appropriate number of VC-rich food is a disease-effective. All types of fresh green leafy vegetables and fruits are a good food supplement VC.

4, iron-rich food

The study found that a lack of iron the body can be caused by T-lymphocytes and B-lymphocytes to generate damage, the quantity and quality of performance for the decline in phagocytic cell function weakened, reducing the number of natural killer cells, such as changes in immune function. The iron-rich food the body can not conducive to the above-mentioned changes in disease resistance have been corrected, returned to normal, to achieve the purpose to combat influenza infection. Such foods are animal blood, milk, eggs, spinach, meat. But too much should not be blindly partial eclipse, in particular, is an iron-fortified foods, first, to avoid undermining the balance between trace elements and lower zinc, copper and so the absorption rate, and the other is too much iron storage in the body, may have contribute to bacterial growth and the proliferation of defects.
