If you want an easy way to cut your risk of type 2 diabetes, go for more orange and green veggies! In a study that followed the dietary habits of over 37,000 Europeans for a ten-year period, those consuming the most carotenoids, specifically alpha and beta-carotene, cut their risk of type 2 diabetes up to 22 percent. Carotenoids are plant-based pigments known for their robust antioxidant power as well as their brilliant orange to reddish hues. Because oxidative stress plays a role in the underlying pathology of type 2 diabetes, these results are not surprising.
