A-types don't fare so well with any Hemp products.
Yes, there are a lot of variables to the BTD thing.
But, metabolically there is a lot of validity to it - too bad we can't test the food ourselves.
The main difference these days though that makes the BTD better is the advent of secretor testing. I have to admit I tried years ago and felt worse, but come to find out I am a non-secretor {most people are secretors which is what the original diet was geared toward}.
I'm still not sure really WHAT Hemp product caused you problem though.
