Is Peanut Butter Good For You?

There are some potential health benefits of peanut butter, especially if you eat a high-quality product without added ingredients, like sugar, salt or preservatives.

1. Improves Satiety

Because it provides protein, fat and fiber, peanuts and other nuts help improve satiety, so you may feel satisfied for a longer period of time after eating a meal or snack with peanut butter. When consumed in moderation, peanut butter may support weight loss and maintenance.

A review published in the Journal of Nutrition found that when nuts were included in adult diets, it improved weight loss. Researchers concluded that when consumed in moderation, nuts enhance palatability and nutrient quality without posing a threat to weight gain.

2. Rich in Micronutrients

Peanut butter provides a range of micronutrients that offer a range of health benefits. It’s a good source of:

  • manganese
  • magnesium
  • phosphorus
  • niacin
  • vitamin B6
  • zinc
  • folate
  • vitamin E

These vitamins and minerals support cardiovascular health, reduce inflammation, promote bone health and support healthy cognitive function.

Magnesium, for example, helps support healthy blood pressure, ease or prevent migraines, relieve PMS symptoms, and normalize blood sugar levels.

In addition, research indicates that niacin, or vitamin B3, helps prevent conditions like high LDL cholesterol, arthritis and diabetes.

3. Good Source of Protein

Research shows that when you’re bodybuilding or engage in regular exercise, getting high-protein ingredients into your meals every day is important. Nut butters are some of the best plant-based foods for a quick boost of protein before or after a workout.

Peanut butter nutrition is also a source of calories, or energy, that is used by the body to power you through an intense session.

In addition to their health benefits for exercise and muscle recovery, plant-based proteins help protect us against heart conditions, reduce inflammation, aid weight loss and promote longevity.

4. Helps With Blood Sugar Management

A 2021 study published in the Journal of Nutritional Science found that among overweight prediabetic adults, a nut-based snack product is a healthier alternative to a cereal-based product with the same calorie count.

The nut-based product causes a lower glycemic response, even in high-risk, overweight and prediabetic adults, according to the study.

Why Some Is Unhealthy

While there are some health benefits of eating peanut butter in moderation, there are some downsides to keep in mind before you get that spoon ready. Here’s a breakdown of the potential drawbacks:

1. Too Much Omega-6 Fat

For starters, most Americans get way too many omega-6 fats in their day-to-day diets and not enough omega-3 fatty acids. Remember, omega-3 fats help reduce inflammation, whereas too many omega-6 fats cause inflammation.

Peanut butter is high in omega-6 fats and low on omega-3 fats, so that can cause an imbalanced ratio, especially if its consumed in excess.

A 2002 study conducted by the Center for Genetics, Nutrition and Health concluded that “Western diets are deficient in omega-3 fatty acids, and have excessive amounts of omega-6 fatty acids compared with the diet on which human beings evolved and their genetic patterns were established.”

The ratio is often as high as 20:1 omega-6 fats vs. omega-3 fats, which is astounding considering an ideal healthy ratio is close to 2:1. According to the study:

Excessive amounts of omega-6 polyunsaturated fatty acids (PUFA) and a very high omega-6/omega-3 ratio, as is found in today’s Western diets, promote the pathogenesis of many diseases, including cardiovascular disease, cancer, and inflammatory and autoimmune diseases, whereas increased levels of omega-3 PUFA (a low omega-6/omega-3 ratio) exert suppressive effects.

In addition, too many omega-6 fats can contribute to:

  • asthma
  • type 2 diabetes
  • obesity
  • irritable bowel syndrome
  • metabolic syndrome
  • macular degeneration
  • and more

2. Peanuts Often Contain Mold and Cause Allergies

The second issue is that most peanuts are grown on the ground. They get very moist, and a lot of them contain mycotoxins or mold — and mold also leads to other health issues.

Mold presence is one factor that causes food allergies or inflammatory immune reactions from these types of foods.

3. It’s High in Calories and Fat

Peanut butter spread on an apple or sprouted bread is considered a healthy snack choice but only when you stick to smaller amounts and use a high-quality brand. Remember that two tablespoons has over 180 calories, so a quick snack can turn into a high-calorie moment without you even realizing it.

How to Consume It Healthily

To consume peanut butter for its health benefits, here are some tips:

1. Buy Organic

First, when you buy peanuts, make sure you buy a certified organic brand and, ideally, a type of a peanut called Valencia or Jungle. These are typically not grown in the moisture of the ground. They’re usually grown in bushes off the ground or higher up, and that eliminates the issue with mold.

In addition, Valencia nuts contain monounsaturated fats that lower triglycerides, and they have all nine essential amino acids and the antioxidant resveratrol. Resveratrol is a powerful antioxidant that fights free radical damage produced during everyday bodily functions, such as eating and exercise.

2. Consume with Omega-3 Foods

The second thing that can actually make peanut butter healthy is to consume it with omega-3 fats. You can add in a little bit of beneficial flaxseed oil or take an omega-3 fish oil supplement when you eat peanut butter. This will help you to maintain a healthy omega-6 to omega-3 ratio in your diet.

3. Enjoy in Moderation

Because of its calorie and saturated fat content, enjoying peanut butter in moderation is best. It’s a useful ingredient for family snacks and meals, as long as you don’t overdo it.

Stick to one tablespoon or less per serving.

Risks and Side Effects

If you don’t have a peanut allergy, then eating peanut butter sparingly is considered safe and even healthy.

If you experience any allergy or sensitivity symptoms, like itchiness, hives, congestion, nausea or a tingling sensation, then stop eating peanut butter immediately. Be sure to rule out an allergy before eating it again.
