10. Refined sugars

Refined sugars are known not only to spike insulin levels, but also to be the most preferable food for cancer cells, thus promoting their growth.

Cancers seem to have a sweet tooth. This is a known fact that has been around for many years. The Nobel laureate in medicine German Otto Warburg, back in 1931, first discovered that tumours and cancers both used sugars to ‘feed’ themselves and/or to increase in size. In order to proliferate, cancer cells seem to prefer feeding on fructose-rich sweeteners like high-fructose corn syrup (HFCS); the reason is that HFCS is being metabolised by cancer cells most quickly and easily.

Now it is clear why high-fructose corn syrup is considered to be the worst offender. And since cakes, pies, cookies, sodas, juices, sauces, cereals, and many other extremely popular, mostly processed, food items are loaded with refined sugars and HFCS in particular, this helps explain why cancer rates are on the rise these days.
