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 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.
