Simply eating "normal" foods, avoiding high-fructose corn syrup when possible, and going easy on the sweet desserts, fast food, and heavily processed foods is just fine for most people. While the basic "recommendations" are probably a good guide to go buy, you can't tell me that lobbying wasn't involved in the FP decision.
Would you believe that the ONLY lobbying I heard about was from the Beef Board?
That most RDs wanted MORE plant on it, not less than what was on it?
Believe me, what you got isn't anything like the fighters in the trenches wanted.
