Enrique Gili is a freelance writer covering Lifestyles of Health and Sustainability (Somehow meat heavily laced with isotopes doesn't sound all that appealing. Steaks and chicken fillets laced with rare, heavy forms of elements - "isotope-enhanced" proteins - could strengthen cells and protect them against oxidation, caused by highly-reactive particles, free radicals, that are released in the body as a by-product of biological processes in our cells. Many researchers believe free-radical oxidation is a major cause of ageing.
In small-scale studies, nematode worms - used extensively in ageing research - lived 10% longer when fed nutrients enriched with a heavy isotope of hydrogen, deuterium. ( Guardian Unlimited)
