article imageStudy: Cutting calories promotes long life

By Gordon K. Chan     Apr 16, 2010 in Health
Studies have consistently found that lowering caloric intake has anti-aging benefits. Less complex organisms can live double, even triple the lifespan if calories are restricted.
Less is more when it comes to calories and health, say nutrition and longevity experts.
Cutting caloric intake by 10 to 50 percent in animals decreases the incidents of disease. Specifically, cancer, cardiovascular and cognitive deficits were non-issues when the animals reached advanced age, reports Science Daily.
"They [the animals on a calorie-restricted diet] eventually die, but they don't get sick", says the author of the study.
In contrast, 94 percent of the animals on a standard diet, developed and died of a chronic disease.
The different diets reveals changes in the molecular pathways related to aging. Calorie restriction reduced the activity in these pathways, thereby considerably increasing the lifespan of those on the diet.
The "profound influence of calorie restriction in animals", is counter-intuitive for a western society where obesity is on the rise, regardless of its potential benefits. However, researchers are adamant that those who practice the strict diet can hope to survive past 100 years old.
The researchers believe that with further study, this approach will promote health and lessen the need for people to rely on drastic interventions or medicines when reaching their advanced years.
