te provoaca sa gandesti
Un studiu efectuat pe barbati cu risc scazut de cancer de prostata a aratat ca adoptarea unui stil de viata sanatos (mai multa activitate fizica si o dieta pe baza de fructe, legume si cereale integrale) provoaca schimbari la nivelul ADN-ului, activand gene care favorizeaza preventia bolilor si dezactivand pe cele care favorizeaza bolile.
Cu alte cuvinte, ar cam trebui sa nu mai tot dam vina pe mostenirea genetica...
"(Reuters) - Comprehensive lifestyle changes including a better diet and more exercise can lead not only to a better physique, but also to swift and dramatic changes at the genetic level, U.S. researchers said on Monday.
In a small study, the researchers tracked 30 men with low-risk prostate cancer who decided against conventional medical treatment such as surgery and radiation or hormone therapy.
The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation.
As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes.
After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off.
The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences (...)"
