Lesson 1

Real pistachio. Zero nonsense.

What's in the jar, and why it's there.

  1. 1

    Dry-roasted peanuts

    The Professor Nutz base, roasted for deep peanut flavor.

  2. 2

    Raw pistachio

    Real pistachio blended right in. The prince himself.

  3. 3

    Pandan leaf & almond extract

    The secret behind the gelato-style flavor.

  4. 4

    Corn fiber

    The heart of Digestibility Corrected. It binds to fat in the gut, so more of it passes through undigested.

  5. 5

    Sweetener

    Soluble tapioca fiber, thaumatin and stevia, with a little molasses. Glycerol monostearate keeps it smooth.

Allergens: Contains peanuts and tree nuts (pistachio, almond). Check the jar label for full allergen information.
The full ingredient list: Dry Roasted Peanuts, Corn Fiber, Glycerol Monostearate, Raw Pistachio, Molasses, Pandan Leaves, Almond Extract, Sweetener (Soluble Tapioca Fiber, Thaumatin, Stevia).
Lesson 2

44 calories. Digestibility, corrected.

Get your scientific brain on for a moment.

  1. What you eat isn't what you absorb

    Normal labels count every calorie in the food. Digestibility Corrected is an FDA term for correcting that count to the calories a food actually yields.

  2. Fiber binds to fat

    Professor Nutz adds natural fiber that binds to fat in the gut, so more of it passes through undigested.

  3. What lands on the label

    44 calories, 0g digested fat and 4g digested carbs per two-tablespoon serving, with 7g of protein.

Copycats copy labels. They can't copy a study.

Plenty of jars talk about low calories now. Ask to see their own published, peer-reviewed study. Ours is right up there.

Stir before use

It's a natural nut butter, so it can separate. A good stir brings it right back.

Two level tablespoons

That's one serving. Measure it once and you'll see how generous 44 calories† can be.

The fine print

The label, by the numbers.

No asterisks hiding anywhere. Well, one dagger.

†Nutritional Facts are Digestibility Corrected. Digestibility Corrected is an FDA term used to represent a correction in calorific yields from a food or macronutrient. Digestibility may vary on an individual basis. The % Daily Value (DV) tells you how much a nutrient in a serving of food contributes to a daily diet. 2,000 calories a day is used for general nutrition advice.

Ask the Professor.

Is it really only 44 calories?
Yes, Digestibility Corrected†. That's the calories your body actually yields from a two-tablespoon serving, not a conventional count of everything in the jar. Digestibility can vary from person to person.
What does Digestibility Corrected mean?
It's an FDA term for correcting a label's calorie count to the calories a food actually yields. Professor Nutz adds natural fiber that binds to fat in the gut, so more of it passes through undigested.
Is there real pistachio in it?
Yes. Raw pistachio is blended into the peanut butter, with pandan leaf and almond extract.
Has it been studied?
The original Professor Nutz peanut butter was the subject of a published, peer-reviewed pilot study in 2020: two weeks of overfeeding with no significant fat gain.
Why does it separate?
It's real peanut butter, so natural oils can rise to the top over time. Stir them back in and you're good.
Who should skip it?
Anyone with a peanut allergy. Contains peanuts and tree nuts (pistachio, almond). Check the jar label for full allergen information.
