I wouldn't worry about the glycemic index. What you do need to worry about is the amount of carbs you plan on taking in, not the response. If you eat lower carb, you'll induce a lower response. If you're gonna eat it in a meal, who cares. It's all gonna get mixed up with fat and induce a low glycemic response anyways. The whole glycemic index is worthless. Who's gonna eat a meal of 5 slices of bread or 50 packets of sugar. What they need to do is get the whole glycemic response after a WHOLE meal with all the foods in it, not parts of the meal. A McDonald's Extra Large Value Meal with an extra large soda will definitely induce a greater response than half a chicken and a bottle of water because of the amount of carbs it has. At least that's how I have it played in my head.
