Nutrition Facts
Per 100g

Diet Ratings

KetoAvoid

Wheat flour contains ~76g net carbs per 100g. Refined grain product fundamentally incompatible with ketosis. Even small amounts exceed daily carb limits.

VeganApproved

Flour (wheat, rice, or other grain-based) is a plant-derived whole food with no animal products or animal-derived ingredients. It is a staple vegan ingredient.

PaleoAvoid

Flour is a processed grain product (wheat, rice, or other grains). Excluded from paleo diet regardless of source. Highly processed and not available to Paleolithic humans.

MediterraneanCaution

Refined white flour contradicts Mediterranean diet principles favoring whole grains. However, flour is a traditional ingredient in Mediterranean baking and cooking. Whole grain flour alternatives are strongly preferred.

Debated

Traditional Mediterranean baking uses refined white flour extensively; modern Mediterranean diet guidelines emphasize whole grain flour for better nutritional value and fiber content.

CarnivoreAvoid

Flour is a grain product (wheat, rice, or other plant sources). Plant-derived, high carbohydrate, explicitly excluded from carnivore diet. No animal-derived nutrients.

Whole30Avoid

Flour is made from grains (wheat, rice, corn, etc.), which are excluded on Whole30. Grain-based flours are explicitly prohibited.

Low-FODMAPAvoid

Standard wheat flour is high in fructans. Even small servings (1 tablespoon, ~8g) approach or exceed low-FODMAP limits. Avoid during elimination; use rice flour, oat flour, or certified low-FODMAP alternatives.

DASHCaution

Refined all-purpose flour is not a whole grain and lacks fiber, magnesium, and B vitamins found in whole-grain flours. DASH emphasizes whole grains. Refined flour is acceptable in moderation but should be replaced with whole-wheat flour when possible. Sodium content is negligible.

ZoneAvoid

Refined white flour is a high-glycemic carbohydrate with minimal fiber and no nutritional value beyond calories. The Zone Diet explicitly avoids refined flour products. A 1/4 cup serving contains ~30g carbs with <1g fiber, creating an unfavorable glycemic load. Even whole wheat flour is unfavorable in the Zone framework due to its high carbohydrate density relative to fiber and micronutrients.

Refined white flour is a processed, refined carbohydrate lacking fiber, bran, and polyphenols. High glycemic index promotes inflammatory blood sugar spikes. Lacks the anti-inflammatory compounds of whole grains.

Refined flour is pure refined carbohydrate with no fiber (0.3g per 100g), no protein (10g per 100g is low relative to calorie density), and no satiety benefit. Consumed as a standalone ingredient, it contributes empty calories. Whole grain flours are marginally better but still not a priority food for GLP-1 patients.
