Nearly all of us aren't getting enough of a critical vitamin that supports vision, brain health and even developing fetuses — vitamin E.
The stunning stat: Around 90% of U.S. adults' diets don't contain adequate amounts of vitamin E, studies have shown.
Zoom in: Vitamin E's major function is as an antioxidant. It quietly protects our cells from the oxidative damage caused by chemicals that are formed naturally when we convert food to energy.
- The consequences of oxidative damage — unchecked by vitamin E — include accelerated aging, deterioration of vision and higher risk of diseases such as cancer, diabetes and Alzheimer’s.
- "Vitamin E is kind of like having a fire department," says Maret Traber, a nutritionist at Oregon State’s Linus Pauling Institute. "You only need it if your house is on fire."
Vitamin E is also important during pregnancy, Traber says.
