New Studies on monkeys
The NewYork times reported recently that Richard Weindruch’s team for the University of Wisconsin published an ongoing study in the journal Science, showed an increase in life quality for the group that followed the diet than the group who ate the quantity they wanted. The studies had been going since 20 years and should wait till all the monkeys are dead to confirm the conclusion on cancer protection. The study was published midway as the results even now give a clear indication on the difference between the two groups under the study: one with restrictive diet and the other without.
Studies of people living on the island of Okinawa whose age exceeded 100 supported the view that a low-calorie diet can increase prospects of good health in humans. Studies in rodent showed that it is working in that species. However, Calorie Restriction Diet may be more relevant to short-lived species ( rat= 3 years life expectancy) in which a major loss of food supply would be catastrophic, whereas scientists think that humans have evolved with cultural mechanisms for dealing with such events and might not have to rely on such evolutionary adaptation. That is an opinion, but the fact is still under evaluation.
What exactly is Calorie Restriction Diet
To eat less like 10 to 40 % macromolecules: sugar, protein and fat without losing the micromolecules, vitamin, mineral, fiber and phytochemicals in our diet. All is the quality of the food we eat. A daily meat with complete food will enter in that type of diet. So it is not starving ourselves but to be picky about what we put in our mouth.
