Peanut butter is a calorie-dense spread, though less so than regular butter. It offers valuable nutrients like 'good fats' that combat bad cholesterol, plus fiber, magnesium, potassium, and protein. However, overconsumption can lead to issues. Dr. Frank Lipman, a respected integrative medicine expert, explained to Popsugar that peanuts are legumes, not nuts—a key distinction. They contain phytic acid and lectins, which in excess are hard to digest and may harm the gut.
Serotonin production, 90% of which occurs in the intestines, supports mood, sleep, and appetite. Excessive peanut butter may disrupt this, contributing to digestive woes, mood swings, intense cravings, or insomnia. If you suspect a link, try cutting it out to test improvements, or switch to alternatives like almond, walnut, or macadamia nut butter. Dr. Lipman recommends whole, roasted or raw nuts—unsalted, without added sugars or oils like palm oil—for optimal health.
