Diet Ratings
Black beans contain 20g net carbs per cooked cup. Even small portions (1/4 cup) deliver 5g net carbs. Legumes are fundamentally incompatible with ketogenic carb limits despite being whole foods.
Whole plant food, excellent protein and fiber source. Canned format is acceptable; check for added animal products or processing aids, but standard canned beans are vegan.
Beans are legumes, explicitly excluded from paleo due to lectins, phytic acid, and anti-nutrients. This is a foundational paleo rule with no mainstream dissent.
Legumes are foundational to Mediterranean diet, emphasized for daily consumption. Canned beans provide convenient access to plant-based protein and fiber. Minimal processing with no added sugars.
Beans are legumes (plant-derived). Legumes are explicitly excluded from carnivore diet due to plant origin and anti-nutrients. No exceptions within carnivore community.
Black beans are legumes, which are explicitly excluded from Whole30 for the full 30 days.
Legumes contain GOS (galacto-oligosaccharides), a high-FODMAP oligosaccharide. Black beans are high-FODMAP at any reasonable serving per Monash.
Excellent DASH food: high fiber, potassium, magnesium, plant protein. Canned versions contain sodium (300-400mg per cup), but rinsing reduces by ~40%. Core DASH recommendation for legumes.
Good plant-based protein and fiber, but carb-heavy (~20g carbs per 1/2 cup). Can be used as carb block in Zone meal, but portion must be controlled. Pair with lean protein and monounsaturated fat. Fiber reduces net carb impact.
Excellent source of plant-based protein, fiber, polyphenols, and resistant starch. Anti-inflammatory legume with minimal processing. High in antioxidants. Rinse to reduce sodium if desired. Strongly aligned with anti-inflammatory pyramid.
Excellent fiber (8-9g per cup), good plant-based protein (15g per cup), low fat, nutrient-dense, and supports digestive health. Easy to digest when prepared properly. Ideal GLP-1 companion food. Rinse to reduce sodium if desired.
Nutritional profile

Protein Density
How much protein it packs per calorie.
Controversy Index
Score range: 1–9/10. Higher controversy = more disagreement between diets.
