How the diets react
Diet Ratings
Béarnaise sauce (emulsion of egg yolks, butter, and tarragon vinegar) contains <1g net carbs per 2-tablespoon serving. High fat content (primarily from butter and egg yolks) aligns perfectly with keto macros. Minimal carbs and excellent nutrient density make it ideal for keto cooking.
Classic French sauce made with egg yolks, butter, and tarragon. Contains multiple animal products (eggs and dairy). No vegan version exists in traditional form.
Traditional béarnaise is made from egg yolks, butter, and herbs—all paleo-compliant. However, many commercial versions contain additives, stabilizers, or are made with seed oils. Homemade béarnaise with grass-fed butter is approvable; store-bought versions are questionable.
Strict paleo practitioners may avoid béarnaise if made with any dairy (butter), following Cordain's dairy exclusion. However, most modern paleo accepts butter and ghee-based sauces as compliant.
Béarnaise is made with butter and egg yolks, high in saturated fat and not aligned with Mediterranean emphasis on olive oil. It is a rich, processed sauce contradicting diet principles.
Traditional béarnaise is made with butter, egg yolks, and tarragon/other herbs. The animal-derived base (butter, eggs) is carnivore-compatible, but tarragon and other herbs are plant-derived spices. Most carnivore practitioners would avoid due to herb content; some might accept if made with only butter, eggs, and salt.
Strict carnivore practitioners exclude béarnaise entirely due to tarragon and other plant-based herbs. Some practitioners might accept a modified version using only butter, eggs, and salt, but traditional béarnaise violates the no-spices rule.
Béarnaise is made from egg yolks, butter (or ghee), and herbs/vinegar—all compliant. However, it's a rich, processed-style sauce that some interpret as recreating restaurant food. Homemade with ghee and compliant ingredients is technically acceptable.
Melissa Urban's 'no recreating restaurant/fancy foods' spirit may apply here, though béarnaise is not explicitly prohibited. Official Whole30 allows the ingredients but community debate exists on whether it violates the whole-foods ethos.
Béarnaise sauce is made with egg yolks, butter, and tarragon vinegar reduction with shallots and tarragon. Shallots are high-FODMAP (fructans). Monash University rates shallots as high-FODMAP at any reasonable serving size.
High saturated fat (butter and egg yolks), high cholesterol, and typically high sodium. Rich sauce contradicts DASH principles of limiting saturated fat and cholesterol for cardiovascular health.
Emulsion of egg yolks, butter, and tarragon vinegar. Approximately 11g fat and 0.5g carbs per 2 tbsp. High in saturated fat from butter. Works as fat block but should not be primary fat source. Homemade versions preferable to commercial (which may contain seed oils). Portion carefully.
Emulsified sauce made with butter, egg yolks, and refined ingredients. High saturated fat and calorie-dense. Lacks polyphenols and antioxidants. While tarragon provides some benefit, overall inflammatory profile contradicts anti-inflammatory diet principles.
Butter and egg yolk emulsion: extremely high fat (20g per 2 tbsp), high saturated fat (12g per 2 tbsp), high calories (180 per 2 tbsp), zero fiber. Classic trigger for GLP-1 side effects (nausea, bloating, reflux). Explicitly contraindicated.
