Peanut Butter Nutrition Benefits and Facts

Nutritional summary

Peanut butter consumption is consistently linked to improved cardiovascular health markers, specifically by lowering triglycerides and improving the ratio of LDL (low-density lipoprotein) to HDL (high-density lipoprotein) cholesterol .
Peanut butter contains phytosterols (plant-derived compounds similar to cholesterol), such as beta-sitosterol, which help block the absorption of dietary cholesterol in the digestive tract .
Regular intake of peanuts and peanut butter is associated with a lower risk of incident frailty and may support better physical and cognitive function in older adults .
Early research suggests that while peanut butter is satiating, adding it to a meal may increase overall food intake compared to eating nuts alone, which appears to trigger stronger energy compensation (the body's natural adjustment of calorie intake) .

Interesting fact

The first patent for a peanut paste was awarded in 1884 to Marcellus Edson, who intended it as a nutritious food for people who could not chew solid food.
