Nutrition Facts

Diet Ratings

Keto1/10AVOID

Pure cornstarch is nearly 100% carbohydrate with virtually no fiber. One tablespoon contains ~8g net carbs. Completely incompatible with ketogenic diet.

Vegan10/10APPROVED

Pure cornstarch is a plant-derived carbohydrate with no animal products or animal-derived ingredients. Universally vegan-compliant.

Paleo1/10AVOID

Refined starch extracted from corn (a grain). Highly processed, lacks nutritional density, and violates paleo grain exclusion.

Mediterranean2/10AVOID

Refined starch with minimal nutritional value. Contradicts Mediterranean emphasis on whole grains and minimally processed foods. Rapidly absorbed, lacks fiber and micronutrients.

Carnivore1/10AVOID

Pure plant-derived starch extracted from corn. No animal origin. Directly violates carnivore diet exclusion of plant foods.

Whole301/10AVOID

Cornstarch is derived from corn, a grain. It is explicitly excluded from Whole30 as a processed grain product.

Low-FODMAP9/10APPROVED

Cornstarch is a pure refined carbohydrate with no FODMAP content. Monash University confirms corn-derived starches are low-FODMAP at all reasonable serving sizes.

DASH5/10CAUTION

Refined carbohydrate with minimal nutritional value. Not a whole grain. Acceptable as thickening agent in small amounts but should not be primary carbohydrate source in DASH diet.

Zone2/10AVOID

Pure refined carbohydrate with extremely high glycemic index. Provides no fiber, minimal micronutrients, and causes rapid blood glucose spikes—antithetical to Zone principles of low-glycemic carbohydrate selection.

Refined carbohydrate with no fiber, nutrients, or anti-inflammatory compounds. Rapidly raises blood glucose and insulin, promoting inflammatory responses. No omega-3s, antioxidants, or polyphenols.

Pure refined carbohydrate with zero protein, zero fiber, and zero nutritional value. Empty calories that provide no satiety or nutrient benefit. Causes rapid blood sugar spikes. Incompatible with GLP-1 dietary principles.

Controversy Index

Score range: 110/10. Higher controversy = more disagreement between diets.
