3. Pounding the Pavement

跑大街

Running, particularly on roads, has been blamed for wear and tear on the knees, which can lead to osteoarthritis. But a new study shows that those who run regularly are actually less likely to develop the condition than those who don't.

人们一直认为在大街上跑步对膝盖不好，会导致骨关节炎。但有一项新研究发现，那些定期跑步的人比不跑步的人患上骨关节炎的概率要更小一点。

Regular running can also reduce pain. A study at California's Stanford University found that older people engaging in regular exercise reported 25 percent less musculoskeletal pain than did sedentary people.

定期跑步还可以减少疼痛。斯坦福大学的研究发现，定期锻炼的老年人与那些久坐的人相比，肌骨骼疼痛的情况要少四分之一。

4. Dairy — Fat or No-Fat?

乳制品：增肥还是减肥？

A Harvard University study of nearly 19,000 women reported that high intake of low-fat dairy foods was associated with a greater risk of anovulatory infertility (infertility caused by the lack of ovulation), while intake of high-fat dairy foods was associated with a lower risk.

哈佛大学在对19000名女性做研究后发现，与摄入高脂肪的乳制品的女性相比较，大量摄入低脂乳制品的女性患上无排卵性不孕症的概率要大得多。无排卵性不孕症是一种由于排卵减少而引起的不孕症。
