Peanut Butter: Understanding, Health Benefits, Side Effects, and More

Peanut Butter

According to the National Institutes of Health peanut butter is a popular spread and a good source of protein. However, it can be dangerous to people who are allergic to peanuts and some brands are high in added fats and sugars so is peanut butter healthy or not for most people. Peanut butter is one of the world wide most popular spreads. To many peanut butter lovers it tastes delicious and the texture is simply amazing, especially the way it sticks to the roof of your mouth before it melts. Of course not everyone can enjoy peanuts. Some people are allergic to peanuts and they can even be deadly for a small percentage of the population. But is peanut butter unhealthy for the remaining 99% of people, let’s find out.

What is Peanut Butter?

Peanut butter is a relatively unprocessed food. It’s basically just peanuts, often roasted ground until they run into a paste. Yes this isn’t necessarily true for many commercial brands of peanut butter. These may contain various added ingredients, such as:

  • Sugar
  • Vegetable oils
  • Trans fat

Eating too much added sugar and trans fat has been linked to various health conditions, such as heart disease. Rather than buying processed foods with several added ingredients choose peanut butter with only peanuts and maybe a bit of salt as its ingredients.

It’s a Good Protein Source:

Peanut butter is a fairly balanced energy source that supplies all of the three major macronutrients. A 3.5 ounce portion of peanut butter contains.


22 grams of carbs (14% of calorie) 5 of which are fiber


22.5 grams of carbs (14% of calorie) which is quite a lot compared with most other plant foods


51 grams of fat totaling about 72% of calorie

Even though peanut butter is fairly protein rich it’s low in the essential amino acid methionine. Peanuts belong to the legume family which also includes beans, peas, and lentils. Legume protein is much lower in methionine and cysteine compared with animal protein. Methionine efficiency is usually associated with an overall protein deficiency or certain disease states. Methionine deficiency is extremely rare for people who are generally in good health. On the other hand, low methionine intake has also been thought to have some health benefits.

  • Low in carbs
  • High in healthy fats
  • Peanut butter is fairly rich in vitamins and minerals
  • It’s rich in antioxidants
  • A potential sources of aflatoxins

What are the Health Benefits of Peanut Butter?

Eating peanut butter in moderation and as part of an overall healthful diet may provide the following benefits, such as:

Weight Loss:

Several studies indicate that including peanuts and other nuts in your diet can help maintain weight or even aid in weight loss. This could be because peanuts make you feel fuller, thanks to their protein, fat, and fiber content. A study from 2018 suggests that eating nuts, including peanuts lowers the risk of being overweight or obese. This study analyzed data from over 373,000 people across 10 European countries over 5 years. Previous research involving over 51,000 women found that those who ate nuts at least twice a week had slightly less weight gain over an 8 year period compared to women who rarely ate nuts.

Boost the Heart Health:

Peanut butter contains many nutrients that can improve heart health, including:

  • Monounsaturated fatty acids (MUFAs)
  • Polyunsaturated fatty acids (PUFAs)
  • Niacin
  • Magnesium
  • Vitamins E

The ratio of unsaturated fats (like PUFAs and MUFAs) to saturated fats in your diet is crucial for heart health. It has a similar ratio to olives, which is known for being heart healthy. Eating a lot of nuts may be linked to a lower risk of death from heart disease, or other causes. Some researchers suggest that peanuts in particular are a cost effective way to improve heart health for some people. Studies show that including 46 grams per day of peanuts or peanut butter in a diet plan recommended by the American Diabetes Association for 6 months could improve heart health, blood lipid levels, and weight control for people with diabetes. However, because peanut butter is high in calories, it’s important to limit how much you eat if you’re trying it to avoid gaining weight. Eating more than the recommended amounts will also increase your intake of fat and sodium which isn’t good for your health.

Low in Carbohydrates:

Pure peanut butter has only about 20% carbohydrates, so it’s a good choice for a low-carb diet. It also leads to a minimal increase in blood sugar levels, which makes it suitable for people with type 2 diabetes. In fact, a comprehensive review of eight studies showed that regularly consuming peanut butter was associated with a reduced risk of developing type 2 diabetes over the long term. These benefits are partly due to oleic acid, a primary fat in peanuts, as well as antioxidants.

Managing Blood Sugar Levels:

Without added sugar, it doesn’t significantly affect blood glucose levels, making it a good choice for people with diabetes. The American Diabetes Association suggests replacing saturated fats with monounsaturated fats in your diet and peanut butter, peanuts, and peanut oil are good sources of monounsaturated fat. A small study from 2013, found that eating it or peanuts for breakfast could help women with obesity and a higher risk of type 2 diabetes manage their blood sugar levels. Those who added nuts to their breakfast had lower blood sugar levels and reported feeling less hungry compared to those who ate a breakfast with the same amount of carbohydrates but no nuts. It is also a good source of magnesium, an essential nutrient for people with diabetes. Prolonged periods of high blood sugar can lower magnesium levels, and low magnesium levels are linked to prediabetes and type-2 diabetes.

Reducing the Risk of Breast Disease:

Eating it, especially from a young age, might decrease the risk of benign breast disease (BBD), which raises the chances of developing breast cancer. A study published in the Journal Breast Cancer Research and Treatment found that consuming it and nuts at any age could lead to a reduced risk of BBD by the age of 30. The researchers analyzed data from over 9,000 schoolgirls in the United States. Other legumes like beans and soy, as well as vegetable fats and various nuts, might also provide protection against BBD. Even individuals with a family history or breast cancer had a notably lower risk if they included it and these other foods in their diets.

Rich in Antioxidants:

Just like many natural foods, it is packed with more than just essential vitamins and minerals. It also contains various other biologically active nutrients that offer potential health benefits. It is notably rich in antioxidants like p-coumaric acid, which studies suggest may help reduce arthritis in rats. Additionally, it contains some resveratrol, a compound linked to a decreased risk of heart disease and other chronic illnesses in animals. Although resveratrol has many potential benefits, there’s still limited evidence in humans.

Peanut Butter is Fairly Rich in Vitamins and Minerals:

It is fairly nutritious. A 3.5 ounce (100 grams) portion of it provides many vitamins and minerals, such as:

  • Vitamin E: 60% of the daily value (DV)
  • Vitamin B3 (Niacin): 84 of the DV
  • Vitamin B6: 29% of the DV
  • Folate: 18% of the DV
  • Magnesium: 37% of the DV

It it also high in biotin and contains decent amounts of:

  • Potassium
  • Zinc
  • Selenium

However, it’s important to note that a 3.5 ounce (100 grams) serving contains a total of 597 calories. When compared to low-calorie plant foods like spinach or broccoli, it may not be as a nutrient-dense calorie for calorie.
