The word "starch" has slightly different meanings depending on the context. A chef means one thing, a dietitian speaking carefully in a scientific context something different, and a diet advice writer, writing for a magazine article aimed at the layperson, something different again. In terms of the layman, a starch is any carbo that doesn't taste sweet, it has to be broken down in stages to sugars to be used in the body. Sweet potatos and carrots for example have a mix of sugars and starches, white potatos more starch. Generally the more starch, the slower the digestion, because more stages are needed. That varies a lot for different starches, some are completally undigestible. Some "high fiber" breads have undigestible wood pulp added as filler. > Do root veggies and winter squash contain starch? Yes. But I don't know what exact kinds. Tom
