Does a Calorie Restriction Diet Increase Longevity
On any diet, nutritional choices are very important. Foods such as vegetables are chosen over high sugar foods, high calorie low nutrient foods, and high calorie junk food are to be avoided.
Benefits of Resveratrol
The average American consumes between 2000 and 3000 calories a day.
On a diet to increase longevity a person eats only enough to barley stay alive. Resveratrol helps us to live longer without a calorie restricted diet.
Nearly two hundred years before any experiments, were conducted on calorie restriction.
Benjamin Franklin said, “To lengthen thy life, lessen thy meals.”Now in 2010 65% of Americans are overweight or obese his words ring powerfully true.
Proof that a Restricted Diet Works
Ancel Keys did a study on caloric restriction diet at the University of Minnesota in the 1950s.
He took sixty volunteers who ate an average daily diet of 1,500 calories for three years with a control group who consumed 2,300 calories per day.
The study demonstrated that the calorie-restricted group was healthier. (Keys, lived to be one hundred.)
The calorie restricted group had less visits to the doctor and blood test also showed then to be healthier than the control group.
Does a Calorie Restriction Diet Lower Blood Pressure and Cholesterol
Another experiment near Tuscon, Arizona in a Biosphere 2, concluded that one member of the crew Dr. Roy Walford, persuaded the other members to do their own calorie-restricted experiment.
The crew consumed a low-calorie diet of vegetables, fruits, nuts, grains, and beans, with small amounts of meat, dairy, and eggs.
They lost weight decreased their body mass by 19 percent for the men and 13 percent for the women. Also they had a drop in their blood pressure.
The Genes Behind Calorie Restriction
One theory why calorie restriction works is that it reduced energy production in the cells and therefore led to less toxicity from free radicals.
Theoretically, fewer free radicals should result in less cellular damage and a longer life. Except that antioxidants alone have not been shown to prolong longevity the way resveratrol does.
So What Does the Evidence Show in People?
Were getting heavier and sicker with every generation, this is the first generation since the baby boomers that parents are out living there children.
