Well it depends on the given individual.Some resistant starches will be eaten by bacteria in the colon to produce gas. On the other hand they count as soluble fiber which sometimes makes other people's IBS better (they may handle the gas better with the proper amount of fiber in the diet). Some things like rice varieties with a high glycemic index will be almost totally digested by you and there isn't much left over for the colonic bacteria. The reason your blood sugar goes up fast is you can digest those starches (so low in resistant starch) very quickly and the get in the blood as fast as pure glucose does. Starches with low glycemic index may be more likely to have more resistant starches as fiber and non-digestable starches slow down how fast the glucose gets into your blood.It is something worth playing around with, but whether they will be helpful or bothersome seems to be quite individual.K.
