Diet Ratings
Nutritional yeast contains 1-2g net carbs per tablespoon with minimal fiber. While technically keto-compatible in small amounts, it's easy to overuse. Best used as a seasoning rather than a staple food.
Plant-based, whole food derivative with exceptional B12 fortification. Nutrient-dense and minimally processed. Excellent protein and micronutrient source.
Nutritional yeast is a processed byproduct of beer brewing, not a whole food available to Paleolithic humans. While nutrient-dense, it represents modern food processing and is not part of ancestral diets.
Not a traditional Mediterranean food, but minimally processed and nutrient-dense. Acceptable as occasional flavoring agent, not a staple. Some fortified versions contain additives.
iModern Mediterranean diet adaptations increasingly accept nutritional yeast as a plant-based protein and B12 source, particularly for vegan practitioners.
Deactivated yeast (fungal organism), not an animal product. Used as plant-based nutritional supplement. Excluded from all carnivore diet variants.
Nutritional yeast is a processed food product derived from deactivated yeast. While not explicitly listed as excluded, it is not a whole food and contradicts Whole30's emphasis on unprocessed foods. Official Whole30 guidance discourages it.
Nutritional yeast is a deactivated yeast product with no fermentable carbohydrates. Monash University confirms it is low-FODMAP at typical serving sizes (1-2 tablespoons). No oligosaccharides, disaccharides, or polyols present.
Excellent source of B vitamins, protein, and minerals. Low sodium, low fat, minimal calories. Fortified varieties provide B12. Supports whole-food DASH approach. No saturated fat concerns.
Nutritional yeast provides B vitamins and complete protein (2g per tablespoon), making it useful for Zone macros. However, it's calorie-dense and easily over-portioned. Minimal carbs but requires strict measurement to maintain 40/30/30 balance.
Rich in B vitamins, selenium, and chromium. Contains beta-glucans with immune-modulating properties. Minimal inflammatory markers. Low calorie, nutrient-dense addition to meals without added sugars or unhealthy fats.
Excellent protein density (8g protein per 2 tbsp serving) with minimal fat and good fiber. Nutrient-dense per calorie with B vitamins. Works well in small portions. Easy to digest and doesn't trigger GLP-1 side effects. Ideal for boosting protein in small meals.
