Diet Ratings
Sunflower oil is pure fat with zero carbs. While high in omega-6 polyunsaturated fats (less ideal than monounsaturated), it remains keto-compatible. Suitable for cooking and meal prep.
Sunflower oil is extracted from sunflower seeds and contains no animal products or derivatives. It is a standard vegan cooking oil.
Seed oil explicitly excluded from paleo diet. High omega-6 content and modern extraction methods contradict paleo principles.
While plant-based, sunflower oil is high in omega-6 polyunsaturated fats and lacks the polyphenols of extra virgin olive oil. Mediterranean diet prioritizes olive oil as primary fat source.
Plant-derived seed oil. Plant oils are explicitly excluded from carnivore diet. High in polyunsaturated fats and plant compounds. Carnivore diet specifies animal fats (tallow, lard, ghee) only.
Sunflower oil is a natural fat extracted from sunflower seeds. It is an allowed cooking oil on Whole30 with no excluded ingredients.
Sunflower oil is pure fat with no carbohydrates or FODMAPs. Monash confirms all oils as low-FODMAP at all serving sizes.
Sunflower oil is a DASH-approved vegetable oil rich in polyunsaturated and monounsaturated fats, low in saturated fat and sodium. It supports cardiovascular health when used in moderation (1-2 tsp per serving).
Sunflower oil is omega-6 polyunsaturated fat-dominant, promoting inflammation. Dr. Sears explicitly recommends avoiding seed oils in favor of monounsaturated sources. High omega-6 to omega-3 ratio violates Zone anti-inflammatory principle.
High in omega-6 linoleic acid (~65%), minimal omega-3. Regular use shifts omega-6:omega-3 ratio unfavorably, promoting systemic inflammation. Explicitly avoided in anti-inflammatory diet.
Sunflower oil is high in unsaturated fats (linoleic acid) and vitamin E, but is calorie-dense (120 cal per tablespoon, 14g fat). For GLP-1 patients eating small portions, even 1 tablespoon of oil is a significant fat load that may trigger nausea. Best used sparingly (1-2 teaspoons) or as a spray. Preferable to saturated fats but portion control is critical.
