Diet Ratings
Vegetable oil contains 0g net carbs with 14g fat per tablespoon. While carb-compatible, it is highly processed with poor omega-6 to omega-3 ratio, making it suboptimal for keto.
iSome keto practitioners view vegetable oil as acceptable for cooking purposes when whole food fat sources are unavailable, focusing primarily on carb content.
Plant-derived oil blend (typically soybean, canola, or sunflower), minimally processed. Completely vegan with no animal products.
Vegetable oil is a generic seed oil requiring industrial extraction and refinement. Not available to ancestral humans. High in omega-6 PUFAs, often contains trans fats. Explicitly excluded from paleo diet by all authorities.
Highly processed, typically high in omega-6 polyunsaturated fats and low in antioxidants. Not traditional Mediterranean. Contradicts core principle of minimizing processed oils.
Plant-derived seed oil with high polyunsaturated fat content and industrial processing. Explicitly excluded from carnivore diet.
Highly processed seed oil blend. Not approved in Whole30 due to processing methods and inflammatory profile contrary to program philosophy.
Vegetable oil is low in FODMAPs at all serving sizes. Monash University confirms low-FODMAP status. Pure oil contains no fermentable carbohydrates.
Generic vegetable oils vary widely in composition. Often high in omega-6 polyunsaturated fats; may contain refined/processed ingredients. DASH guidelines prefer oils with clear monounsaturated fat profiles like olive or canola.
iUpdated clinical interpretation suggests some vegetable oils (soybean, sunflower) are acceptable in DASH when used in moderation, though NIH DASH guidelines recommend prioritizing olive and canola oils for their superior nutrient profiles and established cardiovascular benefits.
Extremely high in omega-6 polyunsaturated fat from seed oils (soybean, corn, safflower). Highly inflammatory and directly contradicts Zone's anti-inflammatory principles. Dr. Sears explicitly recommends avoiding seed oils.
Typically soybean or seed oil blend. Extremely high omega-6 polyunsaturated fats with minimal omega-3. Heavily refined, bleached, and deodorized—removes any polyphenols. High heat processing creates oxidized compounds. Pro-inflammatory profile. Explicitly avoided in anti-inflammatory protocols.
Vegetable oil is calorie-dense (120 cal/tbsp) with zero protein or fiber. While unsaturated fats are preferable to saturated, any oil is problematic on GLP-1 due to reduced appetite and high fat worsening nausea/bloating. Only acceptable in tiny amounts for cooking or dressing.
