Glycemic index of snacks & crackers
Snack foods split into two groups: refined, low-fat snacks like pretzels and rice cakes are high GI, while fattier snacks like potato chips test lower. A lower GI from added fat does not make a snack healthier, so look at the glycemic load, fiber and overall nutrition too.
