So far, so good. The amylase inhibitor is a poison to an insect who would depend upon the starch for survival. It is not a poison to us, because we don't. > Is there supposed to be an amount of this stuff that is safe to consume? Why not? We avoid ingesting too many carbs because we don't like their effects in high concentrations. So why would it be unsafe to consume a substance that helps us to do what many of us are trying to do anyway? The amylase inhibitor is an anti-nutrient, but a potentially useful one. Which beans is this enzyme found in? I wonder how much of it remains after cooking. This might explain the fact that beans tend to have low glycemic index, but the more they are cooked, the higher it goes. > I, for one, am amazed that "the other side" has the same information we have, > and yet they literally use it towards > their own ends, and claim it's a good thing. How can there be such directly > opposite views of the same information?? If this, the presence of amylase inhibitor, were the only reason not to eat beans, I'd say it was no good reason at all. It would be a good reason to eat them, in fact, because it would mean that their protein:carb ratio is more favorable than it seems. What is more serious is the fact that the beans also contain protease inhibitors, which interfere with protein digestion, and lots of lectins, some of which may have unwanted effects on the immune system. To the extent that this "trimplex" isolates the amylase inhibitor from the other things, I'd say it is a good thing for people who are unwilling to limit their consumption of carbs.
