PEANUT BUTTER DOES WHAT？! Eat This and Watch What Happens ｜ Dr. Mandell

Peanut butter has been misunderstood for years. Because it’s rich, calorie-dense, and contains fat, many people automatically assume it’s a food they should avoid—especially when they’re trying to manage their weight or improve their metabolic health. But what matters isn’t simply whether a food contains fat; it’s the overall nutritional package and how it fits into your diet. Natural peanut butter provides predominantly unsaturated fats along with plant protein, fiber, magnesium, vitamin E, niacin, and other beneficial nutrients and plant compounds. That combination of fat, protein, and fiber can help slow digestion, increase fullness, and make a meal or snack more satisfying, which may help reduce the urge to keep reaching for highly refined foods between meals. Peanut butter can also change the way carbohydrates affect you when the foods are eaten together because adding fat, protein, and fiber to a carbohydrate-containing meal can slow digestion and moderate the rise in blood glucose compared with eating the carbohydrate by itself. Peanuts and other nuts have also been extensively studied as part of dietary patterns associated with cardiovascular and metabolic health, and replacing foods high in saturated fat with foods containing more unsaturated fats can help support healthier cholesterol levels. Peanut butter also provides fiber that contributes to digestive health and regularity, while its nutrient density makes a relatively small serving surprisingly satisfying. The important part is choosing a peanut butter that is primarily peanuts—ideally without large amounts of added sugar or hydrogenated fats—and remembering that portion size still matters because peanut butter is calorie-dense. Try a spoonful with an apple, celery, oatmeal, or a smoothie, or simply enjoy it by itself. And these principles aren’t limited to peanut butter; almond butter and other minimally processed nut butters can provide many of the same nutritional advantages. Healthy eating isn’t about fearing fat or labeling one food as magical—it’s about choosing nutrient-dense foods that help you stay satisfied and make your overall diet easier to maintain. If you’ve been avoiding peanut butter because you thought it was automatically “fattening,” this video may completely change the way you look at that spoonful.
