Radiation is not uncommon around us, such as going to the hospital for medical checkups and visits, taking an X-ray, doing a CT or whatever, so we can’t completely get away from radiation exposure in our lives. However, because the human body has a complete and efficient defense and repair mechanism, occasionally receiving a low-dose radiation exposure will not cause meaningful damage to the body, an X-ray or a single CT scan people do not need to worry too much, to ensure normal water, nutritionally balanced food intake can be. If the health needs and have to accept a larger dose of radiation examination, treatment, people can also be through the diet to counteract or reduce the damage caused by nuclear radiation to the human body. We may talk about the construction of anti-radiation food from the mechanism of nuclear radiation damage to the human body: a large number of rays acting on the human body, will cause the body’s macromolecules distortion, and even stimulate the body’s water molecules to produce free radicals, and then damage biological molecules, resulting in radiation sickness. For this reason, the construction of anti-radiation food in general should include: high protein, multivitamins, moderate fat, nutritionally comprehensive, and sufficient quantity. Six dietary principles to help you resist radiation (1) the energy supply to be sufficient, sufficient energy supply is conducive to improving the body’s tolerance to nuclear radiation, reduce sensitivity, reduce damage, protect the body, the daily energy supply 4000-4500 kcal. (2) sugar supply has a focus, such as the abdomen after short-term exposure to large doses, because the human digestive tract may be damaged, resulting in its absorption of various sugars are not the same, so the effect of prevention and control of digestive tract damage is also different, including the best fructose, glucose, followed by sucrose, dextrin, etc.. (3) lipid content should not be high. Based on the human body after radiation loss of appetite, poor taste, the total supply of fat should be properly reduced, but need to increase the proportion of vegetable oils, of which oleic acid can promote the regenerative function of the hematopoietic system, the best effect of prevention and control of radiation damage. (4) protein to have quality. Requires the intake of protein of excellent quality and sufficient quantity to reduce radiation damage and promote the body to restore health. (5) inorganic salt supply is appropriate to increase the amount. An appropriate amount of inorganic salt (mainly table salt) in the diet can encourage people to drink more water and accelerate the excretion of radionuclides with urine and feces, thus reducing internal radiation damage. (6) The amount of vitamins should be ensured. Increase the supply of vitamins to prevent radiation damage and post-injury recovery are effective, such as VK to reduce bleeding, VPP to reduce vomiting, nausea, VC to accelerate the regeneration of blood cells, etc. For this reason, it is appropriate to consume more kelp, cabbage, carrots, honey, wolfberry, etc.. In addition to drinking green tea can also play a certain role in anti-radiation, green tea contains tea polyphenols, which can reduce the adverse effects of various kinds of radiation on the human body. Tea also contains lipopolysaccharides, can improve the body’s hematopoietic function, raise platelets and white blood cells.
