Refined carbohydrate with no fiber, minimal nutrients, and high glycemic index. Does not align with DASH emphasis on whole grains and nutrient density.
Pure refined carbohydrate with extremely high glycemic index (~85). No nutritional value beyond calories. Causes sharp insulin spike. Fundamentally incompatible with Zone diet principles.
Refined carbohydrate with high glycemic index, no fiber, no nutritional value. Promotes blood sugar spikes and inflammatory response. Provides empty calories.
Pure refined carbohydrate with zero protein, zero fiber, zero fat. Empty calories that provide no nutritional value. Spikes blood sugar rapidly. Every calorie counts on GLP-1; cornstarch wastes precious appetite capacity.
