Is adding peanut butter to a smoothie healthy?

Quick Answers

Adding peanut butter to a smoothie can be a healthy choice depending on the ingredients used and how often it is consumed. Peanut butter provides protein, healthy fats, fiber, vitamins and minerals. However, it is also high in calories and should be consumed in moderation. For a nutritious peanut butter smoothie, use ingredients like milk, yogurt, fruits, vegetables, seeds, nuts and nut butters. Limit added sugars, processed ingredients and excessive calories. Enjoy peanut butter smoothies occasionally as part of a balanced diet. Moderation is key.

Nutritional Profile of Peanut Butter

Peanut butter is a good source of several important nutrients:

Nutrient Amount in 2 Tablespoons of Peanut Butter
Calories 188
Fat 16 g
Saturated Fat 2.6 g
Monounsaturated Fat 6.7 g
Polyunsaturated Fat 4.4 g
Protein 8 g
Fiber 2 g
Manganese 0.5 mg (24% DV)
Magnesium 49.5 mg (12% DV)
Phosphorus 137 mg (14% DV)
Folate 67.5 mcg (17% DV)
Niacin 4.5 mg (28% DV)
Vitamin E 2.9 mg (15% DV)

*DV = Daily Value

The healthy fats in peanut butter are mostly monounsaturated and polyunsaturated fats, which can help lower LDL (bad) cholesterol when consumed in moderation as part of a balanced diet. Peanut butter also provides a good amount of protein and fiber per serving.

The manganese, magnesium, phosphorus, folate and niacin in peanut butter support bone health, energy production, DNA synthesis, and more. Vitamin E acts as an antioxidant in the body to protect cells.

However, peanut butter is high in calories, providing nearly 200 calories in just 2 tablespoons. Most of the calories come from fat. Peanut butter is also easy to overeat. Consuming too many calories from peanut butter can contribute to weight gain over time.

So while peanut butter can be a healthy choice, portion control is important. Adding a couple tablespoons of peanut butter to a smoothie can provide nutrition without going overboard on calories.

Benefits of Adding Peanut Butter to Smoothies

Adding a tablespoon or two of peanut butter to a smoothie can provide these benefits:

More Protein

Peanut butter boosts the protein content of smoothies. Just 2 tablespoons provides 8 grams of plant-based protein. This helps make smoothies more satiating. Protein also supports muscle growth and maintenance.

Healthy Fats

Peanut butter contributes heart-healthy fats like monounsaturated and polyunsaturated fats to smoothies. These support cardiovascular health when consumed in moderation. The fat in peanut butter also helps absorb the fat-soluble vitamins from other ingredients.


Each serving of peanut butter provides about 2 grams of fiber. This enhances the fiber content of smoothies, which benefits digestion and gut health. Fiber also promotes feelings of fullness.

Vitamins and Minerals

Adding peanut butter to smoothies boosts the vitamin and mineral content with manganese, magnesium, phosphorus, folate and more. These support bone health, energy levels, immunity and other functions.

Flavor and Texture

Peanut butter enhances the flavor, creaminess and texture of smoothies. It complements many ingredients popularly used in smoothies as well, like bananas, chocolate, oats and nuts.

So in moderation, peanut butter can be a nutritious addition that provides protein, healthy fats and other benefits.

Potential Downsides of Peanut Butter in Smoothies

There are a few potential downsides to keep in mind with adding peanut butter to smoothies:

High in Calories

Peanut butter is very energy dense, packing nearly 200 calories into 2 tablespoons. Adding multiple tablespoons of peanut butter to a smoothie can create a high calorie beverage. This is fine occasionally but regular high calorie smoothies could contribute to weight gain.

May Contain Added Sugars

Some peanut butters have added sugars, like honey, maple syrup, sugar or high fructose corn syrup. Check the ingredients list and choose natural peanut butter without added sugars when possible. The sugars in some peanut butters boost the calories without providing much added nutrition.

Contains Oxalates

Peanuts contain oxalates, an antinutrient that can bind to calcium in the body and promote kidney stone formation in those prone to them. However, clinical studies have found blending and processing peanuts into peanut butter significantly reduces the oxalate content. So this is likely not a major concern.


Peanut butter is one of the most common food allergens, especially among children. Avoid adding peanut butter to smoothies intended for people with a peanut allergy. Seek medical care immediately if someone with a peanut allergy consumes peanut butter.

Overall, the potential downsides are not very significant concerns when peanut butter is consumed in moderation as part of a balanced diet. But they are worth keeping in mind.
