Diet Ratings
Pure cornstarch is nearly 100% carbohydrate (approximately 91g net carbs per 100g). It is a refined carbohydrate thickening agent with zero nutritional value for ketogenic diets.
Pure plant-derived starch with no animal products or animal-derived ingredients. Fully vegan compliant.
Cornstarch is a refined starch extracted from corn, a grain. It is a processed product with no nutritional density and is explicitly excluded from paleo.
Pure refined carbohydrate with no nutritional value. Highly processed and contradicts Mediterranean principles of whole foods.
Cornstarch is a refined plant-derived carbohydrate extracted from corn. Pure plant product with no animal origin, explicitly forbidden on carnivore diet.
Cornstarch is explicitly listed as an excluded ingredient in the official Whole30 rules. It is derived from corn and used as a thickening agent.
Pure cornstarch is low-FODMAP at standard cooking portions. Monash University confirms cornstarch as a safe thickening agent.
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.
Nutritional profile
Six traits that cut across every diet.
Fiber & Plants
How much whole-plant food and fiber it delivers.
Healthy Fats
The quality of its fats (unsaturated, omega-3).
Whole / Unprocessed
How close it is to its natural, unprocessed form.
Gut Gentle
How easy it is on digestion (low FODMAP, few irritants).
Low Glycemic
How little it spikes your blood sugar.
Protein Density
How much protein it packs per calorie.
Controversy Index
Score range: 1–9/10. Higher controversy = more disagreement between diets.
