Lupini beans

16 g carbs with 16 g fiber !!? Have any of you used them? Yesterday when buying some beans, I came across a type I had not heard of before. Its by Unico (which may be a Canadian company) According to the nutrition label:
1/2 cup = 160 calories
5 g. fat 14g protein 16 g carbs 16 g fiber.
I have emailed the company to check that this is not a mistake. So far no reply. Online I have found bits of interesting info, there seem to be several different varieties. However only vague references to actual nutritional info. I believe the numbers pretty much add up however. (Assuming 1/2 the caloric value for fiber carbs). These may be a real find, I’ll have to do some experimenting.
