Green beans contain ~7g net carbs per 100g cooked. Acceptable in small portions (handful) but portion control is essential to stay within daily carb limits. Often considered a 'free' vegetable in lazy keto but stricter practitioners count them carefully.
Whole plant food, nutrient-dense vegetable with no animal products or derivatives. Excellent source of fiber, vitamins, and minerals.
Green beans are technically legumes but are often included in paleo diets because they are consumed immature (pod and all) before significant lectin and phytate accumulation. Many paleo practitioners allow them in moderation, though strict interpretations exclude all legumes.
