Pumpkin seeds contain antioxidants like carotenoids and vitamin E.

They are a good source of antioxidants, magnesium, zinc and fatty acids, all of which may help keep your heart healthy, which can reduce blood sugar and inflammation and protect your cells from harmful free radicals. 

Diets rich in pumpkin seeds have been associated with lower levels of stomach, breast, lung, prostate and colon cancers.
