Japanese researchers measured substances in the blood of nearly 400 children. They found that those with the highest levels of vitamin E-related compounds were at a 67 percent lower risk of eczema.
Although the study does not prove cause and effect, researchers say this study is more precise than earlier research.
Vitamin E-rich foods include sunflower seeds, wheat germ, almonds and some leafy greens.
It is not clear why vitamin E would lower the risk of eczema, but scientists suggest it's antioxidant and immune boosting effect might play a role.
