Una dieta vegetariana persistente puede ocasionar mutaciones genéticas que aumentan el riesgo de cáncer y de enfermedades cardíacas

Long term vegetarianism can lead to genetic mutations which raise the risk of heart disease and cancer, scientists have found.

Populations who have had a primarily vegetarian diet for generations were found to be far more likely to carry DNA which makes them susceptible to inflammation.

Scientists in the US believe that the mutation occured to make it easier for vegetarians to absorb essential fatty acids from plants.

But it has the knock-on effect of boosting the production of arachidonic acid, which is known to increase inflammatory disease and cancer. When coupled with a diet high in vegetable oils - such as sunflower oil - the mutated gene quickly turns fatty acids into dangerous arachidonic acid.

The finding may help explain previous research which found vegetarian populations are nearly 40 per cent more likely to suffer colorectal cancer than meat eaters, a finding that has puzzled doctors because eating red meat is known to raise the risk.
