Diet Ratings
Crème fraîche contains approximately 1g net carbs per ounce with 9-10g fat per ounce. High-fat, low-carb fermented dairy product ideal for keto sauces and cooking.
Dairy cream product made from animal milk. Contains casein and whey, explicitly excluded by vegan standards.
Dairy product (fermented cream) excluded from paleo diet. Fermentation does not remove lactose and casein sufficiently to align with paleo principles.
Very high in saturated fat with minimal nutritional benefit. Cream-based dairy contradicts Mediterranean moderation principles. Better alternatives like Greek yogurt available.
Animal-derived fermented dairy product. High fat content is favorable. Lower lactose than fresh dairy due to fermentation. Accepted by most dairy-inclusive carnivores, but excluded by strict meat-only practitioners.
Lion Diet and strict carnivore adherents exclude all dairy including fermented options. Dairy-inclusive carnivores generally accept crème fraîche for its high fat and lower lactose content relative to other dairy products.
Crème fraîche is a dairy product (cultured cream) and is explicitly excluded on Whole30. All dairy products are not permitted during the 30-day elimination period.
Crème fraîche is a high-fat cream product with minimal lactose. Similar to mascarpone, Monash confirms low-FODMAP status at standard servings (2 tablespoons).
Full-fat dairy product with high saturated fat (5g per tablespoon) and cholesterol. DASH explicitly limits full-fat dairy. Minimal protein or beneficial nutrients relative to calorie and fat content. Not suitable for hypertension management.
Crème fraîche is cultured cream with ~3g fat per tbsp (mostly saturated), minimal protein (0.3g), minimal carbs (0.4g). Better fat profile than mascarpone but still saturated-fat dominant. Usable as flavoring agent in small portions but doesn't provide meaningful protein. Requires pairing with lean protein.
Very high saturated fat cream product (>40% fat). Minimal nutritional benefit beyond calories. Directly contradicts anti-inflammatory guideline to limit full-fat dairy and saturated fat. Similar profile to mascarpone.
Very high fat (40g per 100g), minimal protein (2-3g per 100g), and poor protein-to-fat ratio. Rich, heavy texture significantly delays gastric emptying and worsens nausea. Essentially empty calories despite small portion use.
Nutritional profile
Six traits that cut across every diet.
Fiber & Plants

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.
