New Scientist on Calorie Restriction
(Tuesday April 04 2006)
 | News on calorie restriction from the New Scientist: "People who substantially cut their calorie intake develop some of the traits associated with longevity discovered in animal tests ... these subjects had reduced fasting levels of the hormone insulin, a trait associated with longevity in animal research. They also found that volunteers who restricted their caloric intake by 25% or achieved similar results by cutting calories and upping exercise had a reduced average core body temperature at the conclusion of the six month trial. Lower body temperatures are also associated with longevity. Each of the low calorie groups also showed a small but statistically significant reduction in DNA damage in their blood cells, when compared with the control individuals. This is noteworthy, the researchers say, because some of the chemical by-products of food metabolism attack DNA, which might contribute to cancer and accelerate the effects of ageing." |
