The more you eat the sooner you will leave this planet

Eat (Less) to Live (Longer)
New study reveals why restricting calories may lead to longevity By Nikhil Swaminathan Scientific American, September 20, 2007
SIRT3 and SIRT4 are part of a family called sirtuins. (SIRT1, which helps extend cell life by modulating the number of repair proteins fixing DNA damage both inside and outside the cell's nucleus is also a member.) SIRT is short for sir-2 homologue—a well-studied protein that is known to extend yeast cell longevity. According to Sinclair, all of the mammalian SIRT genes (and their proteins) are possible drug targets for therapies aimed at extending life, as well as staving off age-related illnesses, such as Alzheimer's disease, cancers and metabolic disorders, like diabetes...

Last year, researchers showed that stimulating SIRT1 can help yeast cells live longer. Sinclair, working with colleagues at his company, at Cornell University in New York and the U.S. National Institutes of Health, identified the actions of two more sirtuin genes called SIRT3 and SIRT4. They found the enzymes controlled by these genes help preserve the mitochondria -- little organs inside of cells that provide their energy.
Your Life Is in Your Hands: the Path to Lasting Health & Happiness by Krishan Chopra (Author), Deepak Chopra (Author) Editorial Reviews
"I believe that what you eat matters, but what is eating you up matters much more," writes Krishan Chopra, M.D., in Your Life Is in Your Hands. Chopra, father of Deepak Chopra, combines knowledge from Western medicine and Eastern wisdom to help you engage in those habits that lead to health and well-being, and discard those that produce stress and illness. Western medicine is effective, but it needs to be combined with a lifestyle that includes a healthy diet and exercise plus heart-and-mind habits such as positive thoughts, optimism, zest for life, right action, meditation, and spirituality.
Chopra describes how, for example, your chances of getting a major illness are doubled if you are depressed, anxious, chronically pessimistic, angry, or irritable, and he explains how to alter those emotions. He discusses the concepts of dharma and karma, illustrating them with family stories. Much of the book is philosophical, spiced with case histories and traditional tales, with advice about how to work these themes into your life. --Joan Price --This text refers to an out of print or unavailable edition of this title.
