Human beings are aerobic organisms and cannot survive without oxygen. Except for a few anaerobic bacteria in the world, oxygen is one of the basic substances for all life activities. While oxygen participates in life activities, it also produces reactive oxygen species, which can cause cell damage and lead to disease.
Under normal circumstances, the production and removal of oxygen free radicals in the body are balanced. Among the substances that fight free radicals, some come directly from the diet, and the other part are the anti-free radical substances produced in the body, but in the final analysis they still come from the intake of nutrients. When there is an imbalance of oxygen free radicals in the body, it will cause diseases in the body. It is currently believed that free radicals are one of the pathological foundations of various diseases such as tumors, aging, cardiovascular and cerebrovascular diseases, Alzheimer\’s disease, and cataracts.
Research shows that diets high in antioxidant nutrients reduce the incidence of cardiovascular disease and certain tumors. A variety of nutrients such as vitamin E, vitamin C, beta carotene, selenium and zinc can fight against free radical damage to the body and act as antioxidants.
Many foods are currently known to have strong antioxidant properties, such as kiwi fruit, prickly pear, fish oil (rich in n3 and n6 series polyunsaturated fatty acids), sea buckthorn juice, white fungus, shiitake mushrooms, wolfberry, and bitter melon. wait. In short, dietary supplementation with antioxidant nutrients is a safe and effective method.
