Nutrition And Immunity In Children


Often in first signs of cold parents complain on weak immunity of child imagining badly what signs of illness exactly should cause anxiety. Does your child get diseased with influenza 3 – 4 times a year?

Most likely, in this case there is no need to worry and interfere with process of immunity formation in child. As general strengthening procedures may be recommended cold training of the body, walkings on fresh air and in children over 3 years old taking of natural botanical medicines based on Echinacea juice.

Day regimen
When sleep, rest, exercises, studies, work and food intake occur at one and the same time, then for the body it is easier to turn from one activity to another and there is consumed much less energy. Rhythmic cycle helps the body to effectively recuperate, optimally react on stress and changes, therefore child with an accurate and cozy regimen has more capabilities to meet an attack of bacteria and viruses.

Nutrition
First of all, for adequate development child should consume animal proteins and fats. For cold prevention it is good to eat onion and garlic – natural products containing phytoncides - and also vegetables, fruits and berries of red, orange and green color which do contain great amount of vitamin C.

It is better to avoid flavor enhancer, colorants and synthetic vitamins because they do give an additional load on body systems, provoke allergic reactions and do overload child's immunity because they are taken for a long time without taking into consideration individual needs.

Sugar also overloads immune system, helps to wash away from the body all vitamins and microelements and it would be better to exclude it from baby foods. It is good when meals take place at one and the same time as this helps body to better digest foods.

Vitamins To Maintain Immunity

Nutrition is directly related to immunity. Specific nutrients play particular role in immunity change. Here are some recommendations on taking vitamins and minerals which help to maintain immunity at any age.

Vitamin A

Vitamin A strengthens superficial layer of skin preventing fissure formation through which microbes may enter the body. This vitamin also prevents development of cancerous growths which is connected with stimulatory effects on white blood cells. However, overmuch vitamin A may be toxic for the body. It is better to get daily rate of vitamin A from food than from special drugs. It is recommended to consume 1000 micrograms of it daily For example, a half of new potato contains double daily rate of vitamin A. Also you may find vitamin A in liver, carrot, spinach, cauliflower, lettuce, apricots and watermelon.

Beta-carotene
Beta-carotene transforms into vitamin A in human body. This antloxidant helps to fight free radicals and intensifies capabilities of immune system to fight cancerous diseases. Just as vitamin A, beta-carotine may be found in carrot, spinach, cauliflower and lettuce. Unlike vitamin A, beta-carotene is not toxic and it may be taken as an supplement to foods. It is recommended to take 6 – 9 mg of beta-carotine daily.

Vitamin B6
When older people consume food with low rate of vitamin B6, their immunity becomes much weaker. Dose increase helps to restore immunity to a normal level. It is necessary to consume more than 1.5 mg of vitamin B6 daily.

In order to get 2 mg of vitamin B6 you should eat big bananas daily. Other sources of vitamin B6 are chicken meat, fish, liver, rice, avocado, walnuts, wheat and sunflower seeds. Large dozes (1000 – 2000 mg daily) of vitamin B6 may be toxic.

Vitamin C

Practically vitamin C provides great aid to each part of immune system. Vitamin C prevents viruses from multiplying, increases attacking drive of cells that fight cancerous diseases. Oranges, strawberries, cauliflower, paprika are perfect sources of vitamin C. Normally it is necessary to consume 500 – 1000 mg of vitamin C daily.

Vitamin D
Vitamin D is good for bones strengthening and that is its major function in the body, because immune system cells are developed in bone marrow. The recommended dose of vitamin D is 5 microgrames. One glass of pure milk contains approximately 10 ME, also it may be found in cheese. In human body vitamin D develops under action of sun rays. Ultraviolet accelerates development of vitamin D from a substance in the skin. In summer it is enough to spend 10 - 15 minutes in the sun to get necessary daily doze of vitamin D. Large dozes of vitamin D may be toxic, therefore, health care providers do not recommend it to take it in form of supplemental drugs.
