Convenient as the Electronic equipments like electromagnetic ovens, microwaves and computer are, they also, inevitably inflict people with their high radioactivity. Fortunately, according to the finding of a study published in the famous magazine “nature and science”, some special food can give us a helpful hand to fend off the negative effect of the radioactivity! So, what are they?One: red-colored fruitTomatoes, red grapes and shaddock, with a common feature of red color, are rich in lycope which is especially high in tomatoes and effective in removal of free radical with its great ability to prevent radioactivity, and therefore, great effect will be achieved in preventing cardiovascular diseases, enhancing human immune system, and deferring aging. Moreover, dry and sensitive skin will also be improved. And it is also preventive to ultraviolet! According to a study, people who eat tomatoes or relative products are less inflicted by radioactivity and therefore, their life spans are also longer. It proves that the content of the lycope slumps by 31% to 46% percents in the skin while other elements remain almost in the same level after suntan. Lycope, by way of clearing of free radicals in human bodies, forms a natural protective layer which will in time prevents radioactivity and lessen the harm to human skin. Also, it is helpful for the combination of collagen in the blood with resilin to keep the skin soft. What's worth mentioning is its speckle-removal effect.Two: beansBeans, especially green beans, are proven anti-pollution food of radioactivity. Green bean is traditionally perceived as an antidote to all toxin, a finding which is future confirmed by modern medicine that green beans is instrumental in excretion of toxin, acceleration of metabolism, and prevention of pollution, including radioactive pollution.Three: sea weedsSea weed, a gel-like alkaline substance and a human detergent, is anti-radioactive, as it is high in content of food grade Sodium alginate. And its alkaline property keeps an alkalescency balance within human body. The recommended menu is seaweed and agar soup, and the two fall in the same kin. The combination of the two will enhance the anti-radioactivity effect.Four: hot peppersPepper, a common seasoning, is also preventive to radioactivity. Not only will the whole human immune system be improved by eating peppers, like black peppers, curry, and raw ginger and so on, but also, the DNA of the cells will be protected from radioactivity. Daily eating of peppers will help one to keep healthy!Five: green teaLast but not least is the green tea which also shows good effect in anti-radioactivity.
