From 60 Minutes: Is Sugar Toxic?

Re: From 60 Minutes: Is Sugar Toxic?
Dr. Cantley's explanation that sugar causing spikes in insulin that can stimulate cancer cells that have insulin receptors (1/3 of breast cancer cells were mentioned as being this way), seems to support the idea that Metformin (the diabetes medication) should be helpful to many breast cancer patients since Metformin has been shown to reduce insulin spikes when reacting to the ingestion of sugar and other carbohydrates. Well, at least this is the way I am reading this news---bird

Re: From 60 Minutes: Is Sugar Toxic?
I think you are right about the Metformin and I know of at least one person on the listserv who has started Metformin. When I saw the headline for this article I didn't expect much valuable content (more media hype) however, I have to admit it is very thought provoking. I will be interest to read the cardiac study referenced in the article. As an RD I frequently counsel patients to limit sugars for high triglyceride levels but noting that sugars may also increase LDL levels is very interesting. Toxic is a strong word but as I thought about that I realized I have come to classify saturated fat and trans fats as such. I just read another article in Nutrition Action entitiled "Sugar Belly" (rather than beer belly) which discussed the theory that fructose intake (mostly from added sugars-not fruit) increases abdominal, visceral fat thus increasing cardiac risk, cancer risk, etc. Intuitively, we know we shouldn't eat so much sugar. None would be quite a challenge. Significantly limiting intake is no doubt of benefit.
Thanks for sharing this article. |

I didn't know that some tumors have insulin receptors. Yikes.
