Diet Ratings
Agar agar is a seaweed-derived gelling agent with 0g net carbs and 0 calories per serving. Pure carbohydrate polymer that is not digestible. Excellent for keto desserts and thickening.
Plant-derived gelling agent from seaweed. Vegan alternative to gelatin. Minimally processed and widely accepted in vegan cooking.
Agar agar is a natural gelling agent derived from seaweed with minimal processing (drying and extraction). It's a whole-food thickener with no additives, making it paleo-compatible.
Minimally processed sea vegetable extract used as gelatin substitute. Aligns with seafood principle and is whole-food derived. However, not traditional to Mediterranean cuisine. Acceptable as a functional ingredient in moderation.
Some Mediterranean diet authorities consider agar agar too modern and non-traditional; others accept it as a plant-based alternative to animal gelatin that maintains whole-food principles.
Agar agar is a plant-derived gelling agent extracted from red algae. It is a plant product and explicitly excluded from carnivore diet. No animal equivalent needed for carnivore cooking.
Agar agar is a natural gelling agent derived from seaweed with no excluded ingredients. It is compliant and widely used in Whole30 cooking as a thickener and in recipes.
Agar agar is a seaweed-derived gelling agent with no fermentable carbohydrates. Monash data supports seaweed products as low-FODMAP. Pure agar agar contains only the polysaccharide agarose, which is not fermented.
Seaweed-derived thickener with minimal calories, no sodium, and soluble fiber. Supports DASH emphasis on fiber-rich foods. Minimal processing concerns.
Virtually zero carbs, protein, and fat (~2 calories per gram). Pure soluble fiber from seaweed. Excellent for volume and satiety without glycemic impact. Supports digestive health and polyphenol absorption.
Plant-based gelling agent derived from seaweed with minimal processing. Contains minerals and fiber. No inflammatory properties. Useful for anti-inflammatory cooking without refined gelatin.
Soluble fiber source (nearly 100% carbs are fiber), zero calories, supports digestion and prevents constipation (major GLP-1 side effect), easy to digest, neutral flavor, works in small portions. No protein, so not a standalone meal component, but excellent fiber supplement.
Nutritional profile
Six traits that cut across every diet.
Fiber & Plants
How much whole-plant food and fiber it delivers.
Healthy Fats
The quality of its fats (unsaturated, omega-3).
Whole / Unprocessed
How close it is to its natural, unprocessed form.
Gut Gentle
How easy it is on digestion (low FODMAP, few irritants).
Low Glycemic
How little it spikes your blood sugar.
Protein Density
How much protein it packs per calorie.
Controversy Index
Score range: 1–9/10. Higher controversy = more disagreement between diets.
