Evidence has been accumulating that except where dairying has been carried on for centuries, postweaning inability to digest milk is the norm for humans as well as other land mammals. Given the ethnic diversity of the U.S., there may well be 30 million Americans who cannot drink milk without developing symptoms and many instinctively learn to avoid it. A simple lactose tolerance test is described that establishes the diagnosis.
越来越多的证据表明，除了那些已经有几个世纪乳制品生产历史的地区，断奶后无法消化牛奶是人类以及其他陆地哺乳动物的常态。考虑到美国的种族多样性，很可能有3000万美国人喝牛奶会出现症状，许多人本能地学会避免饮用。本文描述了一种简单的乳糖耐量试验，用于确诊。
