Laboratory studies show calorie restriction can slow aging and now, human studies also suggest slowing of the aging process. Researchers at Columbia University’s Butler Aging Center say this is the first long-term study of calorie restriction in healthy, nonobese humans. Volunteers were on a normal diet or a twenty-five percent reduction in calories for two years. Results were measured by changes in three methods of DNA data known to change with aging. Those on reduced calories suggest a slower pace of aging may be possible, along with a reduction in chronic age-related diseases. One form of the DNA measurement translated to a similar benefit as stopping cigarette smoking. The study appears in the journal Nature Aging.
