Nutritional Profile of a 20g Serving

Natural peanut butter is a simple, wholesome food made from roasted peanuts and sometimes a touch of salt. Unlike conventional versions, it avoids added sugars, emulsifiers, and hydrogenated oils, which keeps its nutritional integrity high. A precise 20g serving, roughly equivalent to a small tablespoon, offers a concentrated source of energy and beneficial macronutrients. This portion size is key for managing its calorie density effectively.

What Makes Up These Calories?

In a typical 20g serving, the calorie distribution is dominated by healthy fats, followed by protein and carbohydrates. This balance is what provides a high degree of satiety, helping you feel full for longer and reducing the urge to snack unnecessarily.

  • Fat: About 70-75% of the calories come from fat. Most of this is made up of monounsaturated and polyunsaturated fats, which are beneficial for heart health by helping to lower bad (LDL) cholesterol.
  • Protein: Providing around 5 grams, the protein in a 20g serving is a great plant-based source that supports muscle repair and growth. This makes it an excellent choice for a post-workout snack or as a way to boost daily protein intake.
  • Carbohydrates: The remaining calories come from carbohydrates, which include dietary fiber. Fiber aids in digestion and contributes to the feeling of fullness. Natural peanut butter typically has a low glycemic index, which helps regulate blood sugar levels.

Essential Vitamins and Minerals

Beyond its macronutrient content, a 20g portion of natural peanut butter is a rich source of micronutrients. These include:

  • Magnesium: Important for muscle and nerve function, as well as blood sugar control.
  • Manganese: Plays a role in metabolism and bone health.
  • Niacin (Vitamin B3): Supports digestive and skin health.
  • Vitamin E: A powerful antioxidant that protects cells from damage.
