However, the absorption rate of yogurt than in milk is high, especially for those who lack lactase.
然而，比牛奶酸奶的吸收率高，特別是對(duì)那些缺乏乳糖酶誰。
Instead, they call it lactase persistence, indicating what's really weird is the ability to continue to drink milk.
相反的，科學(xué)家們把乳糖抗性稱為乳糖耐受性，以表明成年后能夠繼續(xù)喝牛奶才是奇怪的事情。
More than two-thirds of the world's people lack lactase, we Chinese people are more than 80% a lack of lactase.
超過三分之二的世界人口的三分之二缺乏乳糖酶，我們中華民族有超過80%的乳糖酶缺乏。
It contains the sugar lactose, which requires the enzyme lactase for breakdown in the intestinal tract.
它包含糖乳糖，為故障在小腸短文要求酵素乳糖酶。
Lactase substitutes are also available. These are drops that you can add to your meals or drinks to improve your digestion of lactose.
乳糖替代物同樣也是可取的。有可以加入食物和飲料里的滴液，可以增加你對(duì)乳糖的吸收能力。
If you are unable to digest milk (the lack of lactase), it Suannai.
如果您無法消化牛奶（即乳糖酶缺乏），它喝酸奶。
Congenital lactase deficiency is caused by mutations in the gene coding for the lactase enzyme (LCT).

The milk sugar lactose is broken down by the enzyme lactase.
奶中的乳糖由乳糖酶分解。
for those people especially the lack of lactase.
為這些人尤其是乳糖酶缺乏。
Levels of lactase often fall as people grow older and some health conditions can also reduce the production of lactase.
隨著年齡的增長(zhǎng)，乳糖水平會(huì)下降。健康也會(huì)降低乳糖的產(chǎn)生量。
If you are lactose intolerant, you might want to try lactase supplements.
