Don't feel bad, half of us are so stinking confused it is pathedic.
All I know is we are trying to add more fruits and veggies to our diet, as we are not big meat eaters anyway. Still think the best way to go is almost everything in moderation. I have never spent so much time looking stuff up on a computer since I had it, and sometimes the more I read, the more confused I get. Hang in there, we all are in the same boat, as I don't think there is a REAL clear cut answer for everyone. I know somedays I just want to throw up my hands and say...I QUIT!! Good luck....
