Diet Ratings
Spirulina contains approximately 2-3g net carbs per tablespoon with exceptional protein and micronutrient density. High in B12, iron, and antioxidants. Acceptable in typical supplemental amounts (1-2 tablespoons daily).
Spirulina is a blue-green algae that is plant-based, nutrient-dense, and minimally processed. It is universally accepted in vegan nutrition.
Spirulina is a blue-green algae with impressive nutrient density. Not available to most ancestral populations, but some paleo authorities accept it as a nutrient-dense whole food supplement.
iStrict paleo excludes all supplements. Mark Sisson and some functional paleo practitioners accept spirulina as a whole food algae with exceptional nutrient profile.
Spirulina is a nutrient-dense algae but represents a processed supplement without Mediterranean diet tradition. While it contains protein and micronutrients, whole Mediterranean foods provide similar nutrients with better bioavailability and food matrix benefits.
iSome Mediterranean diet practitioners view spirulina as an acceptable modern supplement for micronutrient density, particularly for vegans seeking B12 and complete proteins, though not traditional.
Spirulina is a cyanobacterium (blue-green algae), which is plant-derived. Despite its nutrient density, it is excluded from all carnivore protocols.
Spirulina is a dried algae with no excluded ingredients. It is minimally processed but is a supplement rather than a whole food, which tests Whole30's philosophy.
iMelissa Urban emphasizes whole foods. While spirulina is technically compliant, some community members question whether algae supplements align with eating recognizable whole foods.
Spirulina is a blue-green algae with minimal carbohydrate content and no identified FODMAP compounds. Monash University testing indicates low-FODMAP status at typical supplemental doses (1-3g).
Spirulina is nutrient-dense (protein, iron, B12) but not explicitly addressed in DASH guidelines. May contain contaminants if not properly sourced. Acceptable as supplement but whole foods (leafy greens, legumes) are preferred for DASH compliance.
iSome functional medicine practitioners highlight spirulina's micronutrient density, but NIH DASH guidelines prioritize whole vegetables and legumes for proven cardiovascular benefits and safety profile.
Exceptional protein density (60%+ by weight); minimal carbs; rich in omega-3s and polyphenols; anti-inflammatory. Excellent Zone supplement/addition to meals. Requires pairing with carbs and fat to achieve 40/30/30, but as a protein source is ideal.
Spirulina is nutrient-dense with high protein, gamma-linolenic acid (GLA), and phycocyanin (potent antioxidant). Strong anti-inflammatory and immune-modulating properties. Minimal calories, high bioavailability.
Spirulina is exceptionally nutrient-dense: 4g protein per tablespoon, high in B vitamins, iron, and minerals, with minimal fat (0.3g per tablespoon) and only 20 calories per tablespoon. Excellent protein-to-calorie ratio. Works well in small portions mixed into smoothies, yogurt, or soups. Highly recommended for GLP-1 patients.
