FREE RADICALS & OXIDATIVE DAMAGE / 自由基与氧化损伤

Free radicals are imbalanced molecules that need another electron to achieve a balanced state. To get balanced, free radicals scavenge an electron from any readily available source, including balanced molecules. Free radicals can cause damage to cell membranes, killing cells in your body or damaging DNA, which can cause or exacerbate many different diseases. This damage can also accelerate the aging process and is called oxidative damage.


Where do free radicals come from?Our modern world and lifestyles can increase free radical levels in your body and in the environment. The following—among other factors—increase the levels of free radicals that your body has to contend with:
  • Increased stress levels
  • Higher BMIs
  • Lack of sleep
  • Pollution
  • UV radiation
  • Smoking

自由基是需要另一种电子达到平衡状态不平衡分子。要获得平衡,自由基清除任何现成的源码电子,包括均衡的分子。自由基会损坏细胞膜,在你的身体或损坏的DNA,这可能会导致或加重许多不同的疾病杀死细胞。这种损伤也可加速老化过程,称为氧化损伤。 哪里自由基从何而来? 我们的现代世界和生活方式会增加自由基水平在你的身体和环境。下面,除其他因素外,增加自由基,你的身体有抗衡的水平:

  • 增加的压力水平 
  • 较高的BMI 
  • 睡眠不足 
  • 污染 
  • 紫外线辐射 
  • 抽烟
