Not discounted... but seriously re-evaluated in most respects. I'm not foreign to the nutritional value of carbohydrates and the use of protein in the body. I'm a huge advocate of healthy portions and variety of BOTH in every meal, however I do have a problem when essentially the 6-11 servings of bread, cereal, rice, and pasta are considered "balanced" by only 2-3 servings of the protein group, 2-4 of the furits and 2-5 of the veggies.
If I were eating according to the minimums of the pyramid:
- 3 cups of pasta/6 slices of bread/6 oz. cereal
- 2 whole peices of fruit
- 3 cups of cooked veggies
- 4 oz. lean meat
- 2 cups of milk
I just doubt that I'd be getting enough protein in order to effieciently metabolize all the carbs I would be eating.
In a survey from the associated press (1998) "People stay at the proper weight if they eat only the amount of food needed to fuel their physical activity. Americans now generally eat far more than they need and exercise far less than they should..." Also from that survey around 54% of American adults were overweight and that the percentage has increased by around 1/3 in the past 20 years.
From USAToday article: "A new survey by the NPD Group, a leading market research firm based in Rosemont, Ill., shows that about 62% of adults and 34% of children are overweight or obese, a percentage that has been virtually the same since 2001, says NPD vice president Harry Balzer."

In my opinion, sure signs that "decades of scientific study on nutrition" should be re-evaluated. Not trying to bash the evolution process of science and scientific thinking... just trying to think beyond what's already been said...
Could you explain please? I'm not quite sure what you mean.
