How the diets react
Diet Ratings
Spirulina is extremely low in net carbs (~2g per 2 tbsp), high in protein (60% of calories), and nutrient-dense. Excellent keto supplement for micronutrients.
Cyanobacteria (not animal). Plant-based superfood with complete amino acid profile. No animal products or derivatives.
Spirulina is a blue-green algae supplement, not a whole food available to Paleolithic humans. While nutrient-dense and unprocessed, it's a modern supplement. Some paleo practitioners accept it for micronutrient density; others argue it violates the whole-food philosophy.
Strict paleo advocates exclude all supplements and processed foods, but some modern paleo practitioners (particularly those following nutrient-dense approaches) accept spirulina as a concentrated whole-food source of bioavailable nutrients.
Spirulina is a nutrient-dense algae but not a traditional Mediterranean food. While increasingly available, it is a modern supplement rather than a staple Mediterranean ingredient.
Some contemporary Mediterranean diet advocates include spirulina as a beneficial supplement for additional micronutrients, though it remains non-traditional.
Spirulina is a blue-green algae (plant-derived microorganism). Carnivore diet excludes all plant foods and plant-derived supplements. No animal products.
Spirulina is a whole food algae supplement with no excluded ingredients. It is allowed on Whole30 as a nutrient-dense food.
Spirulina is a microalgae with minimal carbohydrate content and no identified high-FODMAP components. Limited Monash testing exists, but typical serving sizes (1-2 teaspoons) contain negligible FODMAPs.
Clinical FODMAP practitioners note limited Monash University testing on spirulina; some recommend caution due to potential GOS content in algae, though evidence is minimal.
Nutrient-dense algae with high protein, magnesium, potassium, and iron. Low sodium. Supports DASH nutrient targets. Limited direct DASH guideline mention but aligns with whole-food emphasis.
NIH DASH guidelines do not explicitly address spirulina; updated clinical interpretation recognizes it as a nutrient-dense superfood supporting DASH goals, though some clinicians debate bioavailability of certain nutrients.
Spirulina is ~60% protein by dry weight with minimal fat and carbs. Extremely nutrient-dense with polyphenols, omega-3s (ALA), and anti-inflammatory compounds. Low-glycemic. Excellent as a protein supplement or meal enhancer. Small portions (1-2 teaspoons) provide significant nutritional value without disrupting Zone macros.
Spirulina is nutrient-dense with high protein, polyphenols, phycocyanin (potent anti-inflammatory), omega-3 ALA, and antioxidants. Extensive research supports anti-inflammatory and immune-modulating properties. Whole food algae with minimal processing.
Spirulina is a nutrient-dense superfood: 4g protein per tablespoon, 0.3g fat, high in iron, magnesium, B12, and antioxidants. Low calorie (20 calories per tablespoon) with exceptional micronutrient density. Easy to digest and works well in small portions (smoothies, soups). Ideal GLP-1 companion.
