3. Refined Sugars
There is nothing as harmful as refined sugars that we eat every day. Candies, cookies and cakes spike insulin levels. Besides increasing the risk of diabetes, refined sugars are the perfect food for cancer cells. This fact has been known for quite some time now. It was first discovered in 1931 by Otto Warburg, the German scientist and Nobel laureate in medicine. According to Warburg, cancer cells use sugars, their favorite being high-fructose corn syrup. HFCS is known to be metabolized by cancer cells far more readily.
