Glycemic index question

[letsrun4it]

I thought yams and sweet potatos were like the nectar of perfection...but as I'm looking at this glycemic index chart it would suggest eating spaghetti is better, significantly. I realize this must not be the be all/end all because M&Ms have a lower glycemic index number too.....explain please

The glycemic index is based on studies of single test meals. Combining anything on that list with a fat or protein will lower the number dramatically. Use it as a base for food selection and don't worry about yams. They've been a bodybuilding staple for years and will not negatively effect your bodyfat levels unless you're consuming an overabundance of calories.

nah dawg...yams got like the most fiber of all complex carbs....if it taste healthy...it probably is

I imagine in the case of yams the fiber is not taken into account with the glycemic index. Yams are loaded with fiber wihch can significantly slow down absorption.
