白内障是指晶状体混浊引起的一种眼病,多发生于50岁以上的老年人。研究表明,白内障的发生与日常饮食中缺乏维生素C、维生素E和微量元素锌、硒有关。白内障的形成是眼晶体蛋白氧化成不透明斑膜的过程。而维生素C和E是一种强力的抗氧化剂,能阻止或延缓白内障的进展。维生素C又是眼球晶体成分之一,严重缺乏时,易致晶体混浊,引发白内障。微量元素锌在人体的眼中含量很高,锌是构成多种酶的原料之一,以维持正常视力功能。硒与白内障 Cataracts are a type of ocular disease caused by lens opacities that occurs in the elderly over the age of 50. Studies have shown that the incidence of cataracts and diet lacking vitamin C, vitamin E and trace elements of zinc, selenium. The formation of cataracts is the process by which ocular crystal protein is oxidized into opaque plaques. Vitamin C and E are potent antioxidants that prevent or delay the progression of cataracts. Vitamin C is one of the crystal components of the eye, a serious lack of easy to cause crystal opacity, trigger cataracts. Trace elements zinc in the human eye is high, zinc is one of the raw materials forming a variety of enzymes to maintain normal vision function. Selenium and cataract
