Nutrition Facts
Per 100g

Diet Ratings

KetoAvoid

Oat flour contains approximately 15-18g net carbs per 2 tablespoon serving. Even small amounts quickly consume the daily carb allowance and are incompatible with maintaining ketosis.

VeganApproved

Oat flour is 100% plant-based, minimally processed whole grain product. Excellent nutritional profile with fiber and protein. No animal products or derivatives.

PaleoAvoid

Oat flour is a processed grain product derived from oats. Oats are explicitly excluded from paleo diets due to their grain classification, anti-nutrients, and phytic acid content.

MediterraneanApproved

Oat flour is a whole grain product with high soluble fiber, beta-glucans, and minimal processing. Excellent for Mediterranean baking and cooking applications. Supports cardiovascular health.

CarnivoreAvoid

Grain-derived flour from oats. Plant-based carbohydrate source explicitly excluded from carnivore diet. No animal origin.

Whole30Avoid

Oats are a grain and are explicitly excluded during Whole30. Oat flour is a processed grain product and would typically be used to recreate baked goods.

Low-FODMAPApproved

Pure oat flour is low-FODMAP at standard serving sizes (½ cup or ~50g per Monash). Oats are naturally low in fructans and do not contain problematic disaccharides or polyols.

DASHApproved

Whole grain product rich in soluble fiber (beta-glucan), supports cholesterol reduction. Excellent DASH staple with high nutrient density and minimal sodium.

ZoneCaution

Oat flour is moderately glycemic (GI ~55). Two tablespoons (~14g) contain ~10g carbs (1 carb block). Zone protocol allows limited whole grains; oat flour is acceptable if portioned strictly and paired with protein/fat. Better than refined flour but not a preferred carb source—vegetables are prioritized.

Oat flour is a whole grain product rich in beta-glucans, soluble fiber, and polyphenols. Beta-glucans have documented anti-inflammatory and cholesterol-lowering effects. Minimally processed and supports healthy microbiome.

Oat flour is high in fiber (8g per 1/4 cup) and contains beta-glucans that support satiety and blood sugar stability. However, it is calorie-dense (150 cal per 1/4 cup) and low in protein (5g per 1/4 cup). It requires pairing with high-protein ingredients (eggs, protein powder, Greek yogurt) to meet GLP-1 dietary priorities. Best used as a baking ingredient in small portions rather than as a standalone food.
