Just want to add - there is a whole contingent of anti-sugar warriors out there who believe that eliminating all sugar - even glucose- from their diets will “starve” the cancer cells.
While limiting (using in moderation) sucrose is an obvious way to control sugar intake, other foods like plants and vegetables contain various sugars as well. Yes, “natural” but they are metabolized just like Tootsie Rolls for the most part, glycemic loading notwithstanding.
Also, for those who go full-on Atkins or Keto, there’s an evolutionary survival pathway known as gluconeogenesis (GNG) - does just like it sounds: makes new glucose when there is none. So in the absence of carbs - or during intense exercise when glycogen is depleted - your body will switch to breaking down protein and fats to make glucose.
In fact this is the basis of the Atkins diet - you want to be in ketosis so your body will make its own glucose and burn it, thereby burning calories. For all the fad diets out there, this one is probably the only one based on real science.
So whether you eat a plant based Mediterranean diet, Atkins, Keto, vegan, South Beach or any of the myriad choices out there, you will never, EVER, eliminate glucose from your body. And BTW, cancer cells are capable of GNG as well…
As a disclaimer, I got a D in Organic Chemistry in College, almost failed Human Biochemistry in Dental School, but remember this obscure tidbit from all the other nonsense thrown my way….go figure.
