The first food: brightly colored fruits and vegetables.
Spinach and tomato are rich in antioxidants, which can protect immune cells from harmful factors in the environment and strengthen the ability of white blood cells to kill foreign microorganisms. At the same time, it is also rich in vitamin C, which is beneficial to resist the flu and make patients recover soon.
Eating only these is far from making up for the illness. What shall we do? protein added! When a person has a cold or fever, the body will need much more calories than usual to overcome the disease, and the body's immune system will be repaired by injecting various amino acids. When you are invaded by virus, in fact, a large number of antibodies (also called immunoglobulin) are produced in human body, which is actually protein. Protein can neutralize some infectious factors and suppress colds or fever. Protein, which makes the body in a good immune state, mostly comes from eggs, lean meat, bean products and other foods.
Vitamin e is also essential during the flu. Studies have confirmed that adequate vitamin E in the body can obviously enhance the anti-infection ability of cells, whether in the elderly or young people. The study also found that vitamin E intake by human body through diet is usually difficult to reach an effective antiviral immune level, so it is suggested to supplement vitamin E with 200 international units every day to prevent the invasion of influenza. So, what food is rich in vitamin E? Almonds, malt and all kinds of dark green vegetables are ok!
Zinc is very important for regulating immune function and is an indispensable trace element for human body. Because many enzymes in the human body must have zinc to play a role. In addition, zinc can also resist infection. Studies have confirmed that daily intake of 50- 100 mg of zinc can prevent influenza. Seafood, lean meat, coarse grains and beans are all rich in zinc.
Vitamin C is indispensable to human body, which can reduce capillary permeability, make it a barrier to prevent viruses from entering human tissues and protect human organs. Foods with high vitamin C content include green leafy vegetables, tomatoes, cauliflower, green peppers, oranges, kiwifruit, watermelons and grapes. Vitamin C will be lost during heating, so these foods are best eaten raw.
Two more vegetables are recommended: onion and ginger. Ginger has the function of dispelling cold and warming the body, preventing influenza, and the effect is very good. Onions are popular in Europe and America to drink onion juice to treat cough. Studies have confirmed that onion can enhance the immune activity of cells, thus enhancing the overall immune response.
Take a look and pay attention to the vegetables and fruits around you, which may also be a good diet therapy. It saves you the pain of taking medicine and getting sick.
