NUTRITIONIST'S INSIGHT

A banana shake is mostly two ingredients with a spoonful of sugar on top. The banana gives about 105 calories and 14g of natural sugar, a cup of whole milk adds 149 calories, 7.7g protein and 8g fat, and one tablespoon of sugar adds another 49 calories and 12.6g of sugar. That is why the same drink can land anywhere from 150 to 310 calories in published recipes: skim milk and no sugar sit at the low end, whole milk, sugar, ice cream or peanut butter at the high end. Dropping the sugar is the easiest change, since a ripe banana already sweetens the glass. If you drink it after a workout, the 9g of protein is modest, so a scoop of yogurt or protein powder is the usual fix. Blending leaves the calories the same, but a shake is quicker to drink than a banana is to eat, so it is easier to take in the sugar fast.

Myth Busters

MYTH #1: A banana shake is a healthy low-calorie drink.

TRUTH: A 12 fl oz glass with whole milk and a tablespoon of sugar has about 303 calories, close to a small meal. Without the sugar it is about 254, and with skim milk it drops further, but it is not a light drink. USDA FoodData Central: Milk, whole, 3.25% milkfat (FDC 746782); USDA FoodData Central: Sugars, granulated (FDC 169655); USDA FoodData Central: Bananas, raw (FDC 173944)

MYTH #2: The sugar in a banana shake is all natural, so it does not count.

TRUTH: The banana and milk give about 26.7g of naturally occurring sugar, but the tablespoon of added sugar brings the glass to about 39.3g. The American Heart Association counts the sugar you stir in as added sugar, and suggests no more than 25g a day for women and 36g for men. American Heart Association: Added Sugars; USDA FoodData Central: Sugars, granulated (FDC 169655)

MYTH #3: Blending a banana destroys its fiber.

TRUTH: Blending breaks the banana into smaller pieces but does not remove the fiber. The glass still has about 3.1g from the banana. What changes is how fast you drink it, since a shake goes down quicker than a whole banana. USDA FoodData Central: Bananas, raw (FDC 173944); Harvard T.H. Chan School of Public Health, The Nutrition Source: Carbohydrates and Blood Sugar

MYTH #4: Banana shake is a good high-protein recovery drink.

TRUTH: With a cup of whole milk the glass has about 9g of protein. That helps, but it is well under a protein shake or a Greek yogurt bowl, so add yogurt, milk powder or protein powder if protein is the goal. USDA FoodData Central: Milk, whole, 3.25% milkfat (FDC 746782); USDA MyPlate Kitchen: Fruit Milk Shakes

MYTH #5: Skipping the sugar makes the shake taste bland.

TRUTH: A ripe banana has about 14g of natural sugar, and USDA's own fruit milk shake recipe uses two ripe bananas and vanilla with no added sugar. Riper bananas sweeten the shake more than greener ones. USDA MyPlate Kitchen: Fruit Milk Shakes; USDA FoodData Central: Bananas, raw (FDC 173944)

NutriScore by Health Goals

Health Goal	NutriScore	Why This Score?
Weight Loss		About 303 calories and 39.3g of sugar in one glass, and liquid calories fill you up less than solid food. Skipping the sugar and using skim milk cuts it to about 188 calories. USDA FoodData Central: Milk, whole, 3.25% milkfat (FDC 746782); USDA FoodData Central: Sugars, granulated (FDC 169655); American Heart Association: Added Sugars
Muscle Gain		About 9g of protein and 51g of carbs make it a decent post-workout drink for calories and carbs, but the protein is low unless you add yogurt or protein powder. USDA FoodData Central: Milk, whole, 3.25% milkfat (FDC 746782); USDA FoodData Central: Bananas, raw (FDC 173944)
Blood Sugar Control		About 51g of carbs, 39g of them sugar, drunk quickly. Without the sugar it is about 39g carbs, still a meal's worth of carbohydrate for someone counting. Harvard T.H. Chan School of Public Health, The Nutrition Source: Carbohydrates and Blood Sugar; USDA FoodData Central: Sugars, granulated (FDC 169655)
Heart Health		8.3g fat with whole milk, most of it saturated, and about 106 mg of sodium. The added sugar is the bigger concern, and skim or low-fat milk improves the score. USDA FoodData Central: Milk, whole, 3.25% milkfat (FDC 746782); American Heart Association: Added Sugars
Fiber and Gut Health		Only 3.1g of fiber from the banana, and milk adds none. Oats or chia seeds blended in raise it. USDA FoodData Central: Bananas, raw (FDC 173944)

Blood Sugar Response to Banana Shake

A banana shake has about 51g of carbs in a liquid form, 39g of it sugar, so blood sugar climbs faster than it would from a whole banana. The milk's protein and fat slow it a little, and leaving out the added sugar lowers the peak. Harvard T.H.

Estimated Blood Sugar Response (1 glass of banana shake, 375 g)

Modeled estimate for a person without diabetes, not a measured trace. Individual responses vary.

How to flatten the spike

Skip the added sugar; a ripe banana and milk already make it sweet.
Use half a banana per glass, or a smaller 8 fl oz glass, if you are counting carbs.
Add protein or fat such as Greek yogurt, peanut butter or chia seeds to slow absorption.
Drink it with a meal instead of on an empty stomach.
Take a 10 to 15 minute walk afterward.

Cultural Significance

Banana shake is a standard order at juice stalls and cafes across South and Southeast Asia, the Middle East and East Africa, where bananas are cheap and milk is added fresh. In India it is a common school-break and Ramadan-evening drink, often sweetened with sugar or honey and sometimes topped with nuts. In the US and Europe the same blend usually goes under the names banana milkshake or banana smoothie, with ice cream or yogurt added.
