Aerynne---the soda thing I mentioned was just an extreme example.
I'd never heard of the EMI thing. Very interesting.
I do know that my body can go a LOT further on high protein, veggies, and healthy fats than it can on high carbs(such as a lot of brown rice and less meat and veggies). Other's mileage may vary, though. I think metabolism has a lot to do with it too.
I guess my ideal plate would be 15-25% meat(or other protein), max 25% grains and 50% or more veggies. When I was avoiding all grains and legumes due to allergies, it was more 25% meat/eggs/cheese and 75% veggies and fruits.
Edited to ask: Would you consider my 25% meat/75% veggies and fruits to be low-carb? Because, I mean, veggies and fruits DO have carbs. Just asking...not sure what you consider unhealthy low-carb.
