Hi. I am putting together nutrition guidelines based on paleo concepts. I am trying to debunk this CW: "Complex carbohydrates are broken down more slowly in the body, help provide more energy throughout the day and make you feel fuller a longer period of time. Grains also contain fiber, which has been proven to be good for the heart and promotes proper bowel function."
I would like to find articles (with proper references) that show that fiber found grains is different from that in fruits/vegetables, and any other articles that oppose the USDA-based guideline above. Thanks.
