我们体内每天都在生成自由基,当体内受到细菌或异物入侵时,免疫系统会发挥作用,使白细胞攻击入侵者,此时白细胞会释放自由基,氧化入侵者,也即自由基有保护身体不受细菌等伤害的正面作用。但是一旦自由基大量产生,超过酶所能处理的程度,身体就会发生氧化,如同铁生锈一样。随着氧化程度的逐渐加剧,健康就会亮起红灯,出现很多退行性疾病,如白内障、糖尿病、癌症、动脉硬化等。可以说自由基是人体疾病和衰老的直接制造者,有很多因素还会促使自由基生成如:吸烟、紫外线、剧烈运动、焦虑、摄入过多酒精和脂肪、肥胖、大气污染、残留农药的食物、电磁波和X射线等。生活中有很多食物可以起到对抗自由基的作用,让我们来认识一下吧。
In our body every day, free radicals are generated. When the body is invaded by bacteria or foreign bodies, the immune system will play a role in the white blood cells attacking the invaders. At this time, the white blood cells will release free radicals and oxidize the invaders, that is, the free radicals will protect the body The positive effects of bacteria and other injuries. But once the free radicals are produced in large quantities, more than what the enzyme can handle, the body oxidizes, just as iron rust does. With the gradual increase in the degree of oxidation, health will light up the red light, there are many degenerative diseases such as cataracts, diabetes, cancer, atherosclerosis and so on. Radicals can be said to be the direct cause of human disease and aging. There are many factors that contribute to the production of free radicals such as smoking, ultraviolet light, strenuous exercise, anxiety, excessive intake of alcohol and fats, obesity, air pollution, residual pesticides Food, electromagnetic waves and X-rays. There are many foods in life that act as free radicals and let’s get acquainted with it.
