How the diets react
Diet Ratings
Peanut oil is pure fat with zero carbs and zero protein. Composition is ~51% monounsaturated, ~32% polyunsaturated, ~17% saturated fat. High smoke point (450°F) makes it suitable for cooking. Slightly less ideal than saturated fats due to higher PUFA content, but fully compatible with keto.
Plant-derived oil from peanuts with no animal products or processing concerns. Whole food-derived cooking oil.
Peanut oil is a seed oil extracted from legumes (peanuts). Paleo excludes both legumes and seed oils due to high omega-6 content and processing methods.
Peanut oil is acceptable for cooking but not a Mediterranean staple. It lacks the polyphenols and health benefits of extra virgin olive oil. Not prohibited, but should not replace olive oil.
Some Mediterranean diet practitioners accept peanut oil as a neutral cooking oil alternative when olive oil is unavailable, though it is not preferred or traditional.
Plant-derived oil from legume (peanut). Explicitly excluded from carnivore diet. Contains plant compounds and polyunsaturated fats not aligned with carnivore principles.
Peanuts are legumes and explicitly excluded. Oil derived from peanuts remains non-compliant regardless of processing.
Peanut oil is a pure extracted oil with no fermentable carbohydrates. Monash University rates all pure oils, including peanut oil, as low-FODMAP with no serving restrictions.
Monounsaturated-rich oil (47% MUFA) with minimal saturated fat (17%). Supports DASH guidelines for healthy oils. Neutral flavor, suitable for cooking. No sodium. Use in moderation due to caloric density.
High in omega-6 polyunsaturated fat (~32%), which promotes inflammation in excess. Contains some monounsaturated fat (~46%) but less favorable than olive or avocado oil. Zone-acceptable for cooking due to high smoke point, but should not be primary fat source. Limit use.
Monounsaturated fat-dominant (similar to olive oil) but higher omega-6 polyunsaturated content than EVOO. Refined versions lack polyphenols. Acceptable for occasional use but not preferred over extra virgin olive oil or avocado oil for anti-inflammatory goals.
Some nutritionists consider peanut oil acceptable due to monounsaturated fat profile and relatively balanced omega-6:omega-3 ratio compared to seed oils. However, Dr. Weil emphasizes olive oil as primary choice.
Unsaturated fat-dominant (47% monounsaturated, 32% polyunsaturated) with some saturated fat (17%). Better than ghee but still 120 calories per tablespoon with zero protein/fiber. High-heat cooking oil acceptable in very small amounts; problematic as a dressing base or for sautéing large portions.
Some GLP-1 RDs accept peanut oil in moderation (1-2 tsp per meal) for cooking lean proteins, citing the unsaturated fat profile; others recommend avoiding all added oils to minimize fat intake and GI distress, preferring cooking sprays or water-based methods.
