I think it is because refined starches are basically seen as sugar by our bodies. I still think eating straight up sugar is
way worse than having white rice or white pasta. But in theory since the bran has been removed, it hits our bodies faster because they are refined.
I, too, would like to know more. Unfortunately those who adhere to Dr. McDougall's Plan still can experience raised triglyceride levels, like my elderly McDougalling relative.
If he has white pasta once ever few months or white rice a few times a month, that is a lot. And his consumption of fruit is only 1-2 servings per day. While his physical activity has been drastically reduced due to disabilities, he still gets in at least 20 (and lately more) minutes of walking everyday. Is the walking at his prior-to-disabilities pace? No. But he at least
is moving.
I would love to know the answers, too, as I want his risk for another stroke to be as low as possible!! By the way, he still is on a baby aspirin and 20 mg. of Prevestatin even though his total cholesterol is always under 150 (even before the stroke and being put on the drug).
