Glycerin Does Not = Feeding Cancer!

When discussing the relationship between glycerin and cancer, it helps to start with what glycerin actually is—spoiler: not a secret cancer snacky snack. Glycerin, or glycerol, is a simple polyol used in foods, pharmaceuticals, and cosmetics. The idea that glycerin “feeds” cancer mostly comes from muddling how cancer cells metabolize sugars and carbohydrates. Yes, cancer cells can be greedy for glucose, but glycerin isn’t sugar, and the body processes it differently.
