Peanut butter has a bit of a reputation—loved for its creamy texture and rich flavor, but sometimes feared due to its fat content. And when people start talking about fats, cholesterol quickly enters the conversation. So, is peanut butter a friend or foe to your cholesterol levels? The short answer is: it depends on the kind you’re eating and how much.
Let’s take a closer look at the science, common misconceptions, and what nutritionists are actually saying about peanut butter and its impact on cholesterol.
Understanding Cholesterol First
Before we dive into peanut butter specifically, let’s clear up a quick misunderstanding about cholesterol itself. Cholesterol is not inherently bad. Your body needs it to build cells, produce hormones, and support digestion. What matters is the balance between LDL (low-density lipoprotein, often called “bad” cholesterol) and HDL (high-density lipoprotein, the “good” cholesterol).
Too much LDL can lead to plaque buildup in arteries, increasing the risk of heart disease. HDL, on the other hand, helps clear LDL from your system. Ideally, you want higher HDL and lower LDL.
So where does peanut butter come in?
The Good Fats in Peanut Butter
Peanut butter is high in fat—about 16 grams per 2-tablespoon serving—but the majority of that fat is unsaturated. Specifically, it contains monounsaturated and polyunsaturated fats, both of which are considered heart-healthy.
Monounsaturated fats, found in foods like olive oil, nuts, and yes—peanut butter—can help reduce levels of LDL cholesterol without lowering HDL. That’s a big win if you’re looking to support your heart health without cutting flavor from your diet.
What the Research Says
A growing number of studies support the idea that nut butters, including peanut butter, can be beneficial when consumed in moderation. In fact, regular consumption of peanuts and peanut butter has been associated with reduced risk of cardiovascular disease.
A 2015 study published in JAMA Internal Medicine followed over 200,000 people and found that those who regularly consumed nuts and peanuts had lower mortality rates from heart disease. Other research has shown that swapping saturated fats—like those found in butter or red meat—for unsaturated fats from sources like peanut butter can help lower LDL cholesterol.
However, that doesn’t mean any peanut butter will do.
Watch Out for Added Ingredients
Not all peanut butters are created equal. Many commercial brands contain added sugars, hydrogenated oils (a source of trans fats), and excess sodium. These ingredients can easily turn a healthy spread into a less heart-friendly choice.
Trans fats, even in small amounts, are known to raise LDL and lower HDL—basically the opposite of what you want if you’re watching your cholesterol.
When choosing peanut butter, look for natural or organic varieties with minimal ingredients. The ideal ingredient list? Just peanuts—and maybe a touch of salt, if you prefer.
Portion Control Still Matters
Even with healthy fats, portion size is key. Peanut butter is calorie-dense, with around 190–200 calories per 2 tablespoons. Eating half a jar in one sitting might give you more fat than your body needs at once, even if it’s mostly the “good” kind.
The best way to enjoy peanut butter for heart health is in moderation—think a spoonful on whole-grain toast, in a smoothie, or paired with apple slices for a satisfying snack.
So, Can Peanut Butter Help Lower Cholesterol?
Yes, when incorporated into a balanced diet and consumed mindfully, peanut butter can actually support healthy cholesterol levels. By replacing less healthy fats (like saturated or trans fats) with monounsaturated fats from peanut butter, you can potentially lower your LDL cholesterol and boost your HDL.

Final Thoughts
Peanut butter doesn’t deserve the bad rap it sometimes gets in cholesterol conversations. As with most things nutrition-related, the real answer lies in context. If you’re eating spoonfuls of sugary peanut butter on white bread every day, your cholesterol may not thank you. But a small amount of natural peanut butter in a diet rich in whole grains, fruits, veggies, and lean proteins? That can absolutely be part of a heart-healthy lifestyle.
Ultimately, your heart health isn’t about one single food—it’s about patterns. Peanut butter can be a powerful ally, as long as you’re mindful of quality and quantity.
