拥有一口洁白加玉、排列整齐的牙齿,不仅会增加几分容颜的秀美,而且还能预防和减少消化系统疾病。那么,为了健齿在“吃”上应注意些什么呢?一、多摄入矿物元素:牙齿中的主要成分是钙和磷。钙和磷增多有防止酸性物质腐蚀牙齿的作用,从而可有效地预防龋齿。含钙丰富的食品有乳制品,虾皮、蟹、蛋类等。当钙、磷的比值为1.6时,进入牙齿中的磷灰石的量最大,而牛奶的钙磷比值为1.5,很接近最适宜的比值,因而牛奶中的磷最易被吸收。含磷多的食物还有鱼、蛋、奶、豆类及谷类等。在饮食中还要注意氟的摄入,尤其是饮水中含氟较低的地区更应注意预防龋齿。因为氟
Has a white plus jade, neat teeth, not only will increase the beautiful appearance of a few minutes, but also to prevent and reduce digestive diseases. So, in order to Jianzhe in the “eat” should pay attention to what? First, more intake of mineral elements: the main component of the teeth is calcium and phosphorus. Increased calcium and phosphorus to prevent acid corrosion of teeth, which can effectively prevent dental caries. Calcium-rich foods are dairy products, shrimp, crabs, eggs and so on. When the ratio of calcium and phosphorus is 1.6, the amount of apatite entering the tooth is the largest, while the ratio of calcium to phosphorus in milk is 1.5, close to the most suitable ratio, so the phosphorus in milk is most easily absorbed. Phosphorus and more food there are fish, eggs, milk, beans and cereals. In the diet should pay attention to fluoride intake, especially in areas with lower fluoride in drinking water should pay attention to the prevention of dental caries. Because of fluorine
