Re: Re: It's the FIBER ...

[Guest guest]

I do low fat, veggies also, but I don't see the trade-off of fiber versus CR. I think I can do both.

Question is what's a lot of fiber? See, I just know they aren't feeding those rats what I eat, like broccoli. eg. The rats get some kind of rat chow made mostly with grains.

So they come to some conclusions based on a diet that I will never see.

Not to argue the point, but I can't translate this study into a human diet, other than the generic word "fiber".

Now they need to do some experiments on humans and find out if it's cruciferous or beans, eg.

Regards.
