It may be hard to believe but no food is carb free. Please read this, many if us on low carb have read this book and it is a super tool kit. I have been diabetic 30 years, I've also done Dafne but many of its principles are floored.
THE CHINESE RESTAURANT EFFECT
---------------------------------------------------------------------------------
(Diabetes Solution, page 95)
Years back, a patient asked me why her blood sugar jumped significantly every afternoon after she went swimming. I asked what she ate before the swim. “Nothing, just a freebie,” she replied. As it turned out, the “freebie” was lettuce. When I asked her how much lettuce she was eating before her swims, she replied, “A head.”
The small amount of digestible carbohydrate in lettuce should not by itself have caused her blood sugar jump, even considering the quantity she ate. The explanation lies in what I call the Chinese Restaurant Effect. Some Chinese restaurant meals contain large amounts of protein or slow-acting, low-carbohydrate foods, such as bean sprouts, bok choy, mushrooms, bamboo shoots, and water chestnuts, that can make you feel full.
During and after meals, the stomach empties a slurry of food mixed with liquid into the small intestine. The liquid passes through the small intestine and is absorbed, mostly in the large intestine. The solids stretch the walls of the small intestine as they slowly pass through. Cells in the upper part of the small intestine release hormones that signal the pancreas to produce insulin when they’re stretched. (The pancreas is the gland responsible for manufacturing, storing, and releasing insulin in the body.) Large meals cause greater stretching of the intestinal cells, which in turn will secrete proportionately larger amounts of these hormones.
A very small amount of insulin released by the pancreas can cause a large drop in blood sugar, and so the pancreas produces the less potent hormone glucagon to fine-tune the potential excess effect of the insulin. Glucagon acts to increase blood sugar.
The problem arises when the insulin-producing cells of your pancreas the pancreatic beta cells make little or no insulin. Glucagon is still produced, but adequate insulin is not available to offset its effect.
The first lesson here is: Don’t stuff yourself. The second lesson is: There’s no such thing as a freebie. Any solid food that you eat (even pebbles) can raise your blood sugar if you’re diabetic. Trivial amounts, however, such as a small stick of celery, will have negligible effects.
