- 记得几年前麦吉尔大学的教授就发表过喝牛奶有害的论文，只好四我灭有看到愿望。张医生写的好啊，我们喝牛奶比较少。洛杉矶的牛奶一喝肚子就咕咕叫，有问题的。

- 这个适当的量每个人都不同。谁能掌握牛奶中的含量？但是得癌症的人毕竟是少数，这里有一组数据：Of these, 209,060 were new cases of breast cancer and resulted in 40,230 deaths. Breast cancer is also a disease of aging with an incidence rate of 82.2 new patients per 100,000 in women aged less than 65 years versus 403.8 per 100,000 for those aged 65 years and older。

For you reference only.
Cows neither produce milk all the time, nor do they only produce milk when they are pregnant. In general, cows begin to produce milk when they give birth and will continue to do so until they are "dried-off", which happens when their calf is weaned (beef cows) or when the farmer stops milking them (dairy cows). For most cows, milk production increases until about 90 days after they give birth, and then slowly declines during the rest of the lactation. If a dairy cow is re-bred successfully at 60-90 days following calving, she will usually be "dried-off" after a lactation of about 305 days so that her mammary gland has a chance to re-charge for a couple months before she gives birth to another calf. (A cow's gestation period is about 280 days.) Some cows that do not re-breed can be milked continuously for 2-3 years, but production declines sufficiently over time that this is not usually economically feasible. Consequently, cows with fertility problems get culled from the herd.

- 你引用的资料看来已经过时，好像来自英国，几十年前也许如是。
