In Episode 1 of our Peanut Butter Adventures, we talked about peanut butter’s popularity in the US. We also talked about some of the features of peanut butter that make it so appealing. It’s versatile, kid-friendly, and nutritious.
In this post, let’s talk about two of my favorite topics: nutrition and cost. We’ll look at key nutrients in peanut butter and compare the cost of peanut to the cost of other sources of these nutrients.
Nutrition of Peanut Butter
Peanut butter has 180 calories per 2-tablespoon serving, or slightly more than an ounce. In the Dietary Guidelines, peanut butter counts as a protein and fat. As a plant-based food, it’s cholesterol-free.

Many people know peanut butter for its:
- 13 grams of heart-healthy unsaturated fats

- 3 grams of dietary fiber
This serving also has:
- 16 grams of fat
- 3 grams of saturated fat
- 7 grams of carbohydrates

It’s a fair source of these vitamins and minerals.

Almond Butter, Sunflower, and Chickpea Butter as Nutritional and Functional Alternatives to Peanut Butter
The Centers for Disease Control and Prevention (CDC) say about 6 percent of Americans have any type of food allergy. Among children, about 1 in 50 have a peanut allergy. Almond butter, sunflower seed butter, and chickpea butter are common substitutes.
Almond Butter: A Close But Pricey Swap
Almond butter may be the closest substitute for peanut butter in terms of taste, texture, and macronutrients. It’s far pricier, coming in at about $8-$10 per 16-ounce jar. Here’s a jar of Justin’s Almond Butter – one of the more popular brands. Cashew butter has similar costs and nutritional content.

Compared to peanut butter, almond butter has more calcium, with 8% of the daily value per 2-tablespoon serving. Almond butter is high in vitamin E, an antioxidant, though peanut butter is also a good source. It also has more riboflavin (vitamin B2), though it’s a common nutrient that you can find in many foods.
Peanut butter has slightly more protein and niacin (vitamin B3).
Sunflower Butter: An Option if You Have Peanut and Nut Allergies
Sunflower butter, like SunButter Organic Sunflower Seed Butter in regular, chocolate, and organic varieties, an option if you’re allergic to peanuts and tree nuts like almonds and cashews. It’s especially high in selenium, a mineral which supports antioxidant function in the body.

Compared to sunflower seed butter, peanut butter is higher in protein and fiber.
Chickpea Butter: A Legume-Based Option
Chickpeas, or garbanzo beans, are legumes, just like peanuts are. Chickpea butter is a little different because compared to nuts, seeds, and peanuts, chickpeas or garbanzo beans are naturally lower in fat. To make chickpea butter, you have to add oil. Check the list of ingredients and nutrition facts panel to see what type of oil it contains. Palm oil and hydrogenated oils can add unhealthy saturated fats.
Chickpea butter can be higher in folate than peanut butter. It has more fiber, too. Peanut butter is higher in protein and fat.
