皮肤白不白,主要取决于黑色素细胞合成黑色素的能力。在人的表皮基层细胞间,分布着黑色素细胞,它含有的酪氨酸酶可以将酪氨酸氧化成多醣,中间再经过一系列的代谢过程,最后便可生成黑色素。黑色素生成的多,皮肤就越黝黑;反之,则皮肤就越白晰。哪些食物会使皮肤变黑?研究证明,酪氨酸酶的活性与体内的铜、铁、锌等元素,密切相关。经常进食富含酩氨酸和稀有元素锌、铜、铁的食物,例如动物内脏肝、肾,甲壳类动物蛤、蟹、河螺、牡蛎。水产品乌鱼子,豆类
White skin is not white, mainly depends on the ability of melanocytes to synthesize melanin. In the human epidermal basal cells, the distribution of melanocytes, which contain tyrosinase can be tyrosine oxidized to polysaccharides, the middle and then through a series of metabolic processes, and finally can generate melanin. The more melanin generated, the darker the skin; the other hand, the clearer the skin is. Which foods will make the skin dark? Studies have shown that the activity of tyrosinase and the body of copper, iron, zinc and other elements are closely related. Regular consumption of foods rich in glutamic acid and rare elements zinc, copper and iron, such as animal offal liver, kidney, crustacean clams, crabs, river snails, oysters.
