Winter comes. Every year winter brings many happy messages. In the meanwhile, winter has become a nightmare for some. This is because they often suffer from colds or flu. No matter how warm the clothes , blankets are used. They inevitably have to suffer. It would be better to strengthen the body's immune system than all these post-disease measures. Some of the vitamins and minerals that are present in our food can help in this work. Whatever we eat , we need to be able to boost our body's immune system. This defense system will destroy the invading viruses and bacteria. But the military cells of the defense system are replaced by new cells every few days. One or the other survives one day. And when the virus enters the body, up to 10 million antibodies can circulate in the bloodstream to corner it. Although almost every vitamin and mineral participates in some way or another, here are the 5 essential diseases and their sources. 'Flu' resistant copper is one of the components of blood , white blood cells , which act as one of the germs fighting against germs. In order to protect the body, they also need to be given the necessary nutrition. Copper will be at the top of the list , which will greatly help the growth of the particles. Copper-rich foods include Shimai , Mudi , Beans , Pulses , Peas , Saffron Potatoes , Dhemp , Olakchu , Snails , Manakchu and Chocolate. Flu-resistant Vitamin E As in other fields, the body's immune system weakens with age. Even healthy elderly people after the age of 65 can produce very little chemical medium called cytokahl. The germs that enter the body have fewer macrophages ; Natural killer cells are also reduced. And giving extra vitamin E can double the required cytokine production. In other words, vitamin E doubles some of the immune systems. Good sources of vitamin E are sunflower seeds , sesame seeds , peanuts , wheat , lettuce leaves , jaggery , corn , vegetable oils , fish and fish fats , eggs and poultry. Folic acid and vitamin B-12 are needed when the number of cells is increasing rapidly in the fight against the flu-resistant folic acid and vitamin B-12 germs . Like zinc, these vitamins (B vitamins) are abundant in the bones. And inside the bone is the bone marrow, the factory that makes these cells. Lettuce leaves , cabbage , kidneys , beans , oranges , green leafy vegetables , nuts , sunflower seeds , jab , corn, etc. are rich in folic acid. Vitamin B-12 is found only in animal foods such as liver , eggs and milk . 'Flu' Resistant Zinc Zinc is essential for keeping the body's immune system alive. One of the many functions of zinc was to oversee the production of germ-destroying cells in the bone marrow. It also traces the thymus gland. In the thymus, white blood cells are specially altered to form T cells. One of the main sources of zinc is a variety of copra , peas , sesame , linseed , cereals , beef and marine plants. After the flu-resistant quercetin-destroying viruses destroy the body cells, a number of 'free radicals' accumulate in the body which can blow up the body's immune system at any time. Quercetin , a type of natural plant chemical that is found in large quantities in vegetables and fruits , activates the immune system by inactivating those added elements. (One of the sources of cassetin is onion , apple, especially apple skin) , black tea , garlic , pepper , blackberry and blackberry , grape and tomato.
