1. vitality

Energy is the basic requirement for us to maintain our body functions. When the human body struggles with invading pathogens, it also needs to consume energy. Therefore, during the COVID-19 epidemic, the first thing we should do is to have three meals a day and ensure that we can provide enough energy for our bodies. In this extraordinary period, we should stand aside for dieting and losing weight.

2. protein

Protein is also important for maintaining body function. Immunoglobulin, cytokines and other components needed for anti-virus need to be synthesized by protein. If the human body lacks protein, it will lead to a decline in disease resistance. Therefore, in order to enhance disease resistance, protein is essential.

vitamin

Vitamin A: Vitamin A is closely related to the health of epithelial tissue, so it is very important to prevent respiratory tract infection. Many studies at home and abroad show that if the elderly and children lack vitamin A, they are prone to pneumonia. Therefore, in the emergency period of preventing COVID-19, we must pay attention to vitamin A supplementation.

Vitamin B: B vitamins participate in the synthesis of various substances in the human body. When the metabolic rate of human body rises due to stress, infection and fever, the body will consume more B vitamins, especially vitamins B 1, B2, nicotinic acid and pantothenic acid. Therefore, to prevent COVID-19, B vitamins are also indispensable.

Vitamin C: Vitamin C is related to the synthesis of antibodies. If the body lacks vitamin C, it will affect the production of antibodies during infection, and then affect the disease resistance. When the human body is already in an infected state, the demand for vitamin C will be higher, so it is also important to prevent COVID-19 and supplement enough vitamin C. Is it necessary to take vitamin C supplements? Nutrition experts say that if healthy people don't need to take a lot of vitamin C supplements for prevention, they just need to eat enough vegetables and fruits, and in the process of eating fruits and vegetables, they can also take other vitamins such as vitamin A and vitamin B at the same time, and the effect is better.

4. Minerals

Adequate minerals are also an important element to enhance resistance. For example, people with anemia are prone to lack of oxygen due to iron deficiency, and their resistance will decline. Others are prone to anxiety, which may be due to the lack of calcium and magnesium. To supplement minerals, you can eat more miscellaneous grains, whole grains, beans, milk, fruits and vegetables.

5. Antioxidant components

Antioxidant components such as selenium and flavonoids can also reduce the damage of inflammatory reaction to body tissues. Fruits and vegetables, beans, whole grains, green tea, chrysanthemum tea, honeysuckle tea and other scented teas can provide rich antioxidant components.

In a word, we need to pay attention to all aspects of nutrition to prevent COVID-19 and improve our resistance.
