Diet Ratings

Keto9/10APPROVED

Fermented fish sauce contains virtually zero carbs (0g per teaspoon) and provides umami depth. Excellent keto flavoring with no carb impact.

Vegan1/10AVOID

Fish sauce is made from fermented fish and salt. It is an animal product by definition. Completely non-vegan. Plant-based alternatives exist.

Paleo9/10APPROVED

Fermented fish and salt only—minimal processing, nutrient-dense, excellent umami flavor. Authentic fish sauce contains no additives. Highly paleo-compatible.

Mediterranean5/10CAUTION

Southeast Asian condiment derived from fermented fish. While fish-based (Mediterranean-aligned), it is highly processed and very high in sodium. Not traditional to Mediterranean cuisine but provides umami flavor.

iSome Mediterranean practitioners accept fish sauce in minimal amounts as a flavor enhancer, drawing parallels to traditional fermented Mediterranean condiments. However, sodium content remains a concern.

Carnivore8/10APPROVED

Made from fermented fish and salt. Pure animal product with minimal processing. Widely accepted across all carnivore protocols including strict Lion Diet approaches.

Whole309/10APPROVED

Pure fish sauce made from fermented fish and salt is compliant. It contains no excluded ingredients and is approved by Melissa Urban as a seasoning.

Low-FODMAP8/10APPROVED

Fish sauce is made from fermented fish and salt with no high-FODMAP ingredients. Fermentation and small condiment servings (1 teaspoon) keep FODMAP load low. Monash University supports fish sauce as low-FODMAP.

DASH1/10AVOID

Extremely high sodium (~1,400mg per tablespoon). Fermented anchovy product. Even minimal amounts exceed DASH sodium targets. Incompatible with both standard and low-sodium DASH variants.

Zone7/10APPROVED

Fish sauce is primarily fermented fish with minimal carbohydrates and no added sugars. Provides umami flavor with negligible caloric impact. Rich in omega-3s and amino acids. Excellent Zone condiment used in small quantities.

Fish sauce provides omega-3 fatty acids and is fermented (beneficial bacteria). However, very high in sodium and has strong flavor requiring small amounts. Used in tiny quantities, inflammatory impact is minimal.

iSome strict anti-inflammatory advocates avoid due to high sodium; however, typical serving sizes (1 tsp per dish) provide negligible sodium load and meaningful omega-3 benefits.

GLP-1 Friendly8/10APPROVED

Fish sauce is essentially zero calories, zero sugar, and provides umami flavor that enhances satisfaction from small portions. High in sodium but used in tiny amounts (1/2 tsp). Supports protein-rich dishes without adding fat or digestive burden. Excellent for GLP-1 patients seeking flavor without calories.
