Walnuts contain 1.9g net carbs per ounce with 18.5g fat and 4.3g protein. Excellent omega-3 source. Superior fat profile for keto. Portion control recommended.
Whole plant food with exceptional omega-3 content, protein, and fiber. Minimally processed. Superior nutritional density.
Walnuts are whole, unprocessed nuts with excellent omega-3 fatty acid content. Available to hunter-gatherers and universally approved in paleo diets. No processing required.
Excellent source of omega-3 fatty acids and polyphenols. Strongly encouraged in Mediterranean diet. Supports cardiovascular health and cognitive function.
Tree nuts are plant seeds and excluded from carnivore diet. High omega-6 polyunsaturated fat profile from plant source.

Walnuts are low-FODMAP at standard serving sizes (14 halves or 28g per Monash). High in omega-3 fatty acids and minimal fermentable carbohydrates. No FODMAP concerns at typical portions.
Core DASH nut. Exceptional source of omega-3 fatty acids (ALA), fiber, and polyphenols. Predominantly unsaturated fat. Low sodium. Strong evidence for cardiovascular and cognitive benefits.
Walnuts are excellent source of omega-3 ALA and provide protein, but are high in omega-6 linoleic acid (2.5g per ounce). Zone protocol emphasizes omega-3/omega-6 balance; walnuts tip toward omega-6. Usable in moderation but not ideal.
Exceptional source of ALA omega-3 fatty acids. High in polyphenols and antioxidants. Dr. Weil specifically recommends walnuts as cornerstone of anti-inflammatory diet. Strong research supporting cardiovascular and cognitive benefits.
Walnuts provide moderate protein (4.3g per ounce) and good fiber (1.9g per ounce), but are very high in fat (18.5g per ounce). High omega-3 content is nutritionally valuable, but fat density can worsen GLP-1 side effects. Portion control critical — small amounts acceptable, but easy to trigger nausea/bloating.
