Diet Ratings
Zero carbs with good fat content and high-quality protein. Whole food. Affordable and accessible.
Fish is animal flesh; all seafood is excluded from vegan diets.
Catfish is an unprocessed whole fish available to hunter-gatherers. It is nutrient-dense and paleo-compliant. Farmed catfish is acceptable, though wild-caught is preferable for nutritional profile.
Excellent fish source meeting 2-3 times weekly recommendation. Low mercury content, good source of omega-3 and protein. Farmed catfish is sustainable and affordable. Aligns well with Mediterranean fish emphasis.
Catfish is a fatty freshwater fish approved on carnivore. Rich in omega-3s and micronutrients. Unprocessed whole fish with no additives meets all carnivore requirements.
Fresh catfish is a whole, unprocessed seafood product fully compliant with Whole30. No excluded ingredients.
Catfish is an unprocessed fish with no FODMAP content. It is a pure protein source, making it low-FODMAP at any serving size.
Excellent DASH fish: low saturated fat (1.3g per 3oz), good protein (19g per 3oz), low mercury, affordable. Farmed catfish is sustainable. When baked or grilled without added fat/sodium, perfectly aligned with DASH guidelines. Core recommendation for fish consumption.
Moderate protein (~20g per 3.5oz) with higher fat content (~11g) than white fish. Fat is more saturated than salmon/mackerel. Acceptable but less ideal than lean fish. Requires careful pairing with low-fat carbs and vegetables.
Catfish has lower omega-3 content than fatty cold-water fish and higher omega-6 ratio. Farmed catfish often fed inflammatory seed oils. Acceptable occasionally but not ideal for anti-inflammatory diet.
Some nutritionists note catfish provides lean protein and is affordable; however, anti-inflammatory experts (Weil, AHA) recommend prioritizing higher omega-3 fish like salmon, mackerel, and sardines.
Catfish is a lean, mild-flavored fish with good protein (~20g per 3oz) and low fat (~4-5g per 3oz). It's easy to digest, versatile, and affordable. Prepare by baking, grilling, or pan-searing with minimal oil. Avoid fried catfish (common preparation) as frying adds significant fat and triggers GLP-1 side effects.
