In “Hope Warshaw’s Pepsi Challenge,” Tom Naughton writes:
In my last post, I commented on a reply from Hope Warshaw — the diabetes educator (ahem, ahem) — to a reader of this blog in which she pooh-poohed his “experience of one” with using a low-carb diet to manage diabetes. The same reader emailed me that he conducted an “experiment of one” in recent days to compare his blood sugar after drinking a 12-ounce Pepsi versus eating some of the foods Hope Warshaw recommends for diabetics. Take a look: Food Carbs BG before BG at 60 mins 12-ounce Pepsi 42 g 89 156 Oatmeal, milk 40 g 113 163 Whole wheat bread 48 g 93 141 Whole wheat toast, milk 36 g 103 173 Perhaps those numbers don’t look scary to you, but they do to me. Here’s what Chris Kresser of The Healthy Skeptic wrote about post-meal glucose levels awhile back:
Even the American Association of Clinical Endocrinologists is now recommending that post-meal blood sugars never be allowed to rise above 140 mg/dL. Unfortunately, less informed groups like the ADA haven’t caught up with the science.The consequences of this are severe. Nerve damage occurs as blood sugar rises above 140 mg/dL. Prolonged exposure to blood sugars above 140 mg/dL causes irreversible beta cell loss (the beta cells produce insulin). 1 in 2 “pre-diabetics” get retinopathy, a serious diabetic complication. Cancer rates increase as post-meal blood sugars rise above 160 mg/dL.
