Soluble/Insoluble fiber, antioxidants?
I like how Cronometer focuses on nutrition, unlike other calorie counters that focus just on macros. I like how it doesn't even just say "vit. A" but it gives you the exact numbers of certain types of this vitamin (just an example).
However, there is no distinction in types of fiber and I find it quite saddening, as soluble and insoluble fiber work differently in the body.
And I personally believe that it wouldn't hurt to try to incorporate some antioxidant data, like ORAC values or something...
