Diet Ratings
Zero net carbs with beneficial omega-3 and omega-6 fatty acids. Excellent for salad dressings and keto meal prep.
Walnut oil is pressed from walnuts, a whole plant source. Fully vegan with minimal processing.
Walnut oil is a seed/nut oil that is highly processed and oxidation-prone. While walnuts themselves are acceptable in moderation, extracted walnut oil concentrates omega-6 polyunsaturated fats and lacks the fiber and nutrients of whole walnuts.
Plant-based oil from nuts, which are Mediterranean staples. Rich in omega-3 fatty acids and polyphenols. Excellent for dressings and finishing dishes.
Plant-derived oil from nuts, explicitly excluded from carnivore diet. High in omega-6 polyunsaturated fats.
Pure pressed walnut oil with no additives. Natural fat from allowed nut, compliant with Whole30.
Pure oil with negligible carbohydrates. Monash confirms oils are low-FODMAP at any reasonable serving.
Walnut oil is excellent for DASH: high in omega-3 ALA (10.4g/tbsp), polyunsaturated fats (72%), and polyphenols. Supports cardiovascular health and reduces inflammation. Low sodium, no added ingredients.
Walnut oil is ~70% polyunsaturated (mostly omega-6 linoleic acid), exceeding Zone's preference for monounsaturated fats. Contains polyphenols but omega-6 ratio is problematic for anti-inflammatory goals.
Walnut oil is rich in alpha-linolenic acid (ALA), an omega-3 fatty acid, and contains polyphenols and antioxidants. It has a favorable omega-6 to omega-3 ratio (approximately 5:1 to 8:1). Dr. Weil specifically recommends walnuts and walnut oil. Best used unheated for dressings and drizzling.
Pure fat (14g per tablespoon, 120 calories) with no protein or fiber. While walnuts contain omega-3 fatty acids, the oil form provides no fiber or protein and is calorie-dense. Empty calories that GLP-1 patients cannot afford. High fat content will trigger nausea and bloating.
