Research on Worms Yields Clues on Aging
...t the drugs did notmimic the anti-aging effects of caloric
restriction, because the wormshad abundant food and looked well-fed. The researchers alsodemonstrated that anticonvulsants did not extend life by protecting theworms from pathogenic bacteria in their environment.Ethosuximide and trimethadione did, ho...
Research may provide new link between soft drinks and weight gain
...fat than the mice that consumed water only. Total caloric
intake was lower in the mice that consumed the fructose-sweetened water than in the other groups, except for the control animals provided with water only. "We were surprised to see that mice actually ate less when exposed to fructose-sweetened bever...
Researchers extend mouse lifespan by protecting against free radicals
...riments by managing their diets and reducing their caloric
intake. Another method relied on the restriction of a growth factor, but a side effect was that the mice suffered from dwarfism. However, neither of those methods of elongating the mouse lifespan was clearly connected to the free-radical theory of ag...
Caloric restriction won't dramatically extend life span in humans: UCLA research

intake by 10 percent, they live longer than if they have unlimited access to food," Phelan said. "If...

New technique multiplies life span in simple organisms
... normal - when the SIR2 deletion was combined with caloric
restriction and/or a mutation in one or two genes, RAS2 and SCH9, that control the storage of nutrients and resistance to cell damage. Human cells with reduced SIR2 activity also appear to confirm that SIR2 has a pro-aging effect, Longo said, althou...

...e culprit. Other diseases that benefit from severe caloric
or protein restriction include kidney failure, type-II diabetes, inflammatory bowel disease and morbid obesity. Overall, Stiehm proposed that new evidence can be found for using certain viruses to treat diseases such as HIV, which do not respond to...

Cutting calories slightly can reduce aging damage
...major importance because it shows a mild degree of caloric
restriction - just enough to prevent weight gain with advancing age - can have beneficial effects against aging. From a scientific perspective, he added, it is important to learn that RNA is a very good marker of aging damage. "I'd never really thou...
