Diet Ratings
Heavy cream contains approximately 0.4g net carbs per tablespoon and 5g fat per tablespoon. It is a keto staple for coffee, cooking, and sauces with minimal carb impact.
Animal product derived from milk. Contains casein and whey. Explicitly excluded from vegan diet.
Heavy cream is a dairy product and is excluded from paleo diet. Contains significant casein and lactose, and is not a Paleolithic food source.
Heavy cream is very high in saturated fat and not part of traditional Mediterranean cuisine. It contradicts core principles emphasizing plant-based foods and olive oil as primary fat source.
Animal-derived dairy product with higher fat content but still contains lactose and casein. Consumed by many practitioners but problematic for those with dairy sensitivity.
Strict carnivore and Lion Diet adherents exclude all dairy including heavy cream. Many practitioners report digestive issues despite high fat content due to lactose and casein.
Heavy cream is a dairy product and is explicitly excluded from Whole30 for the entire 30-day period.
Heavy cream contains lactose but at lower concentrations than whole milk. Monash University data suggests low-FODMAP status at restricted portions (approximately 1/4 cup or 60ml), but high-FODMAP at larger servings.
Monash University rates heavy cream as low-FODMAP at 1/4 cup (60ml) serving, but clinical FODMAP practitioners note lactose content increases with larger portions and individual lactose tolerance varies significantly.
Extremely high in saturated fat (5.5g per tablespoon) and cholesterol. DASH recommends avoiding full-fat dairy products. No place in hypertension management diet.
~5g saturated fat per tbsp with minimal protein (~0.3g) and negligible carbs (~0.4g). Macronutrient imbalance (fat without protein/carbs). Dr. Sears recommends against high-saturated-fat dairy; contradicts monounsaturated fat focus.
Heavy cream is nearly pure saturated fat with high arachidonic acid content. Promotes inflammatory markers. No meaningful anti-inflammatory compounds. Dr. Weil explicitly recommends avoiding. Should be eliminated from anti-inflammatory diet.
Nearly pure fat (36g per 100ml), no protein, extremely calorie-dense (340 cal per 100ml), high saturated fat. Directly triggers nausea, bloating, reflux, and delayed gastric emptying on GLP-1s. No nutritional justification for inclusion.
