11. Refined Sugars
While not as terrible as artificial sweeteners, refined sugar is still something to avoid.
In addition to spiking your insulin levels they provide an excellent fuel source for cancer cells.
Back in 1931, researchers found that cancer cells have a taste for sweets.
They discovered that tumors rely on sugar to increase cancer cell production and size.
Refined sugars, such as high fructose corn syrup, are more easily converted into cancer cell growth than regular sugar.
Sadly, high fructose corn syrup is still found in thousands of products at the neighborhood supermarket.
