Nutrition Facts
Per 100g

Diet Ratings

Keto2/10AVOID

Oat flour contains approximately 54g net carbs per 100g. Even small portions (2 tbsp) deliver 10-12g net carbs, consuming 20-60% of daily keto carb allowance. Incompatible with ketosis maintenance.

Vegan9/10APPROVED

Pure plant-based whole grain flour with no animal products or derivatives. Minimally processed and nutrient-dense.

Paleo2/10AVOID

Oats are a grain product. While some paleo practitioners consume rolled oats in moderation, flour form concentrates carbohydrates and removes any whole-food context. Grains are excluded from strict paleo.

Mediterranean8/10APPROVED

Whole grain product rich in fiber and beta-glucans. Minimally processed and aligns with Mediterranean emphasis on whole grains. Versatile for traditional preparations.

Carnivore1/10AVOID

Plant-derived grain product. Oats are seeds/grains explicitly excluded from carnivore diet. High carbohydrate content incompatible with carnivore principles.

Whole301/10AVOID

Oats are a grain and explicitly excluded from Whole30. Oat flour is a processed grain product.

Low-FODMAP8/10APPROVED

Pure oats are low-FODMAP at standard servings. Oat flour is a concentrated form but remains low-FODMAP when used in typical baking quantities (up to 1/2 cup per serving).

DASH9/10APPROVED

Whole grain product rich in soluble fiber (beta-glucan), which helps lower cholesterol and blood pressure. Low sodium, excellent source of magnesium and potassium. Core DASH food.

Zone5/10CAUTION

Oat flour is a low-glycemic carb source suitable for Zone meals, but lacks fiber of whole oats and requires precise portioning to maintain 40/30/30 ratio. Best used as part of mixed carb-protein-fat meal.

Anti-Inflammatory8/10APPROVED

Whole grain flour rich in beta-glucans (soluble fiber) with demonstrated anti-inflammatory and cholesterol-lowering properties. High in antioxidants and polyphenols. Minimal processing preserves nutrient density.

GLP-1 Friendly5/10CAUTION

Oat flour provides moderate fiber (8g per 1/4 cup) and some protein (5g per 1/4 cup), but is calorie-dense and requires mixing into other foods to be palatable. As a standalone ingredient, it is not nutrient-dense enough per calorie for GLP-1 patients with severely reduced appetite. Best used in small amounts to boost fiber in high-protein recipes (e.g., protein pancakes, meatballs).

Score range: 19/10. Higher controversy = more disagreement between diets.
