染色体的末端——端粒——会随着年龄的增长而缩短，让我们更容易生病。也许你会认为我们对此无能为力就，但最新研究表明，生活习惯的改变可以激发一种增加端粒长度的酶，而且其他研究也发现合理饮食和锻炼能保护端粒。看来健康的生活习惯能从细胞级别减缓衰老。 As we age, the ends of our chromosomes -- called telomeres -- become shorter. This makes people more vulnerable to disease. You might think there's nothing you can do, but new research suggests otherwise. In a pilot study, lifestyle changes boosted an enzyme that increases telomere length. Other studies also find diet and exercise can protect telomeres. So healthy habits may slow aging at the cellular level. |
