Genetic changes that enable lactose tolerance have been detected not just in Europeans but also in three African pastoral societies.(實現乳糖耐受力的基因變化不僅僅只在歐洲，也在三個非洲的放牧社會被發現。)

But this is crazy when most Asians are lactose intolerant.(但是由于亞洲人無法接受乳糖，這件事就變得很瘋狂。)

For example, in individuals with lactose intolerance, the body is unable to break down lactose, a sugar found in milk.(舉例來說，對乳糖——牛奶中所含的一種糖——不耐受的人，身體不能就不能分解乳糖。)

Feeding babies with a so-called lactose allergy soy milk is an absolute disaster.(用乳糖過敏豆奶來喂養嬰兒絕對是一個災難。)

A so-called milk allergy or lactose intolerance is really an intolerance or allergy to pasteurization.(一種稱為牛奶過敏癥或乳糖不耐受癥其實是對高溫消毒后的牛奶的不耐受癥或過敏癥。)

Lactose intolerance stems from a deficiency of the enzyme lactase, which is needed to help digest lactose, a sugar in milk.(乳糖不耐癥的病因是缺乏乳糖酶，這些乳糖酶是消化乳糖的必需物質，牛奶中的糖就屬于此類。)

One person doesn't eat meat, while another is lactose intolerant, or can't digest wheat.(有人不吃肉，有人受不了乳糖，或消化不了小麥。)

Cheese: This is a safe snack for dogs, but just like humans, they can experience lactose intolerance, so monitor your dog's reaction.(奶酪:這是狗狗安全而美味的零食，但和人一樣，狗狗也可能會有乳糖不耐癥。所以給狗狗奶酪時要觀察它的反應。)

The most important representatives of disaccharides are sucrose (from beet or cane), lactose, maltose and cellobiose.(二糖最重要的代表是蔗糖(來自于甜菜或甘蔗)，乳糖，麥芽糖和纖維二糖。)

For example, our ability to digest the lactose in milk after infancy arose after we domesticated cattle.(比如，在馴養了牛之后，我們就進化出了一種在嬰兒時期過后也可以消化牛奶中的乳糖的能力。)
