Low selenium and cancer risks have been
suggested by earlier studies but the answer was not very clear until
In the latest study, researchers looking at over 120,000 men and women between 55 and 69 years of age and followed their health for 16 years. They looked at the selenium levels in their toenails since it is a reliable prediction of the body's selenium levels.
The study revealed that the higher the selenium levels the person had, the less chance that they will develop throat cancer. As for stomach cancer, the relationship to high selenium levels was much weaker. This benefit seems to apply more to women than men.
Moreover, the researchers also discovered that the levels of other antioxidants in their diet along with selenium levels also seem to affect throat cancer risks.
The conclusions that come from this study are that low levels of selenium intake seem to increase the risk of throat cancer and stomach cancer. This risk is even greater if you are a female, a non-smoker and those with low antioxidant levels in their body.
