Vitamin E in canola, other oils hurts lungs

A large new study advances our understanding of vitamin E and ties increasing consumption of supposedly healthy, vitamin E-rich oils — canola, soybean and corn — to the rising incidence of lung inflammation and, possibly, asthma. The good news: vitamin E in olive and sunflower oils improves lungs. The study shows drastically different health effects of vitamin E depending on its form: gamma-tocopherol in soybean, canola and corn oil and alpha-tocopherol in olive and sunflower oils.
