Computers, mobile phones, televisions, microwave ovens, induction cookers, stereos ... If you calculate carefully, home appliances can be described as "mountains". Mountains of household appliances also bring mountains of electromagnetic radiation. Experts suggest that in order to avoid the harm caused by electromagnetic radiation, we should eat the following foods. Black sesame: According to the theory of Chinese medicine, black enters the kidney, "the kidney dominates the bone and ascends the marrow to the brain". All kinds of radiation hazards mainly affect people's brain and bone marrow and damage the immune system. Eating more foods that tonify the kidney can enhance the body's cellular immunity and humoral immunity and effectively protect human health. Amaranth: Amaranth can resist radiation, mutation and oxidation, which is related to its selenium content. Selenium is an important trace element, which can enhance immune function and protect human health. Eating amaranth rich in selenium often can improve the anti-radiation ability of human body. Pepper: Pepper and other spicy foods are common condiments and natural radiation-resistant foods. Eating pepper can not only mobilize the whole immune system, spices such as pepper, black pepper, curry and ginger, but also protect the DNA of cells from radiation damage. Therefore, eating spicy food often will make you healthy. Green tea: Tea polyphenols in green tea are anti-radiation substances, which can reduce the adverse effects of various radiation on human body. Tea also contains lipopolysaccharide, which can improve human hematopoietic function and increase platelets and white blood cells. Vegetables and fruits: Eat more fresh fruits and vegetables and get a lot of vitamins A, B, C and E. These vitamin-rich foods can reduce the subtle influence of electromagnetic radiation on human body and avoid nervous system disorder. Kelp: The latest research found that kelp polysaccharide, the extract of kelp, has anti-radiation effect by inhibiting immune cell apoptosis.
