better genes

Eat right for better genes. If you make nutrition a priority when you're pregnant, scientists suspect that you may lower your child's inherited cancer risks. Simply by eating healthy, adults might be able to mend their own genes, too.

The emerging field of epigenetics is behind these surprises. It's showing that environmental influences can modify how genes function without actually altering DNA. The evidence: Duke University scientists recently reprogrammed the color of mice offspring and left them with diminished appetite, lower body weight, and less diabetes and cancer by enhancing the mothers' prenatal diet with B vitamins and related nutrients.

The nutritional enhancements seem to generate chemical signals that act as genetic stop signs. And studies of human twins and babies conceived through in vitro fertilization suggest that people are subject to similar outcomes.

Experts believe diet can alter your own genes as well. But they caution against gulping down supplements. "All nutrients have multiple genomic effects. So one has to be very careful," says Patrick J. Stover, Ph.D., associate nutritional biochemistry professor at Cornell University . "You may regulate one gene that is not beneficial while silencing another gene that is." by K.A.

I know of no more encouraging fact than the unquestionable ability of man to elevate his life by conscious endeavor.
