How the diets react
Diet Ratings
Bananas are extremely high in carbs: a medium banana contains 27g net carbs. One of the highest-carb fruits, making it completely incompatible with ketosis.
Whole plant fruit with no animal products or derivatives. Ideal vegan food meeting all dietary criteria.
Whole fruit available to hunter-gatherers. Unprocessed, nutrient-dense, good source of potassium. Natural sugars acceptable in moderation.
Whole fruit with excellent potassium, B vitamins, and fiber. Aligns with Mediterranean emphasis on plant-based foods consumed multiple times daily. Naturally sweet without added sugars. Widely available in Mediterranean regions.
Bananas are plant-derived fruit with high carbohydrate and sugar content. Completely incompatible with carnivore diet rules excluding all plant foods.
Bananas are whole fruits with no processing or added ingredients. Fruits are explicitly allowed on Whole30.
Bananas are low-FODMAP at standard servings (1 medium banana = 100g). Monash University confirms low-FODMAP status. Ripe bananas are preferred over unripe.
Excellent DASH fruit. Exceptional potassium source (essential for blood pressure control), good fiber, natural sugars only, low sodium.
High-glycemic carb with poor fiber-to-sugar ratio. One medium banana (~27g net carbs) = 3 carb blocks, spiking insulin. Dr. Sears explicitly lists bananas among high-glycemic fruits to avoid.
Bananas provide resistant starch (especially when slightly green), potassium, and antioxidants. They support gut health and have minimal inflammatory compounds. Ripe bananas have higher sugar but still acceptable in moderation.
Moderate fiber (2.6g) and potassium, but higher sugar (14g per medium banana) and calorie-dense (105 cal) relative to volume. Can cause bloating or nausea in some GLP-1 patients. Better as occasional choice than daily staple.
