Peanuts, often mistaken as nuts, are actually legumes, belonging to the same family as green peas, soybeans, and lentils. These "groundnuts," as they are also known, grow underground as the fruit of the peanut plant, which originated in South America. Americans consume an average of almost 8 pounds of peanuts per year, often in the form of peanut butter. While peanuts are enjoyed in various forms, boiled peanuts, a Southern delicacy, offer a unique nutritional profile and potential weight loss benefits.
What are Boiled Peanuts?
Boiled peanuts are a popular snack in the coastal Southeast, from North Carolina to Mississippi. They are made by boiling raw, green peanuts in salty water for several hours until they become soft. This method of preparation dates back to Africa and gained popularity in the US, particularly in the South, during the Civil War. The shells become soft, and the peanuts inside are tender and mushy, with a distinctive salty flavor.
Nutritional Profile of Boiled Peanuts
Boiled peanuts contain a wealth of essential nutrients, making them a healthy food choice. They are rich in:
- Fiber: Contributes to feelings of fullness and aids in digestive health.
- B Vitamins: Including niacin, folate, thiamin, pantothenic acid, and pyridoxine, which are essential for energy production, red blood cell formation, and nervous system function.
- Vitamin E: An antioxidant that protects cells from damage.
- Minerals: Such as iron, zinc, potassium, magnesium, phosphorus, copper, manganese, and selenium, which play vital roles in various bodily functions, including blood sugar control, blood pressure regulation, protein production, muscle function, nerve function, and muscle contraction.
- Antioxidants: Substances that protect cells from damage and help prevent diseases. Boiled peanuts have nearly four times the number of antioxidants compared to raw or roasted peanuts.
- Amino Acids: Including arginine and all other essential amino acids, which are the building blocks of protein.
- Healthy Fats: Boiled peanuts are a good source of both monounsaturated and polyunsaturated fatty acids, which can help lower unhealthy LDL cholesterol levels and reduce the risk of heart disease.
A 100-gram serving (approximately 1/2 cup) of peanuts provides a significant portion of the recommended daily allowance of several nutrients:
- 75% of niacin
- 60% of folate
- 53% of thiamin
- 55% of vitamin E
- 22% of dietary fiber
Health Benefits of Boiled Peanuts
Heart Health
Peanuts, including boiled peanuts, are beneficial for heart health due to their high content of unsaturated fats, fiber, and plant sterols. These components help reduce the risk of heart disease by lowering LDL cholesterol and blood pressure levels. They also prevent the formation of blood clots and reduce inflammation, both of which are linked to heart disease.

Weight Loss
Foods high in protein can promote feelings of fullness, which can aid in weight loss. Peanuts are high in protein and fiber, which can satisfy hunger for extended periods. Studies suggest that including a moderate amount of peanuts in your diet does not cause weight gain and may even help with weight loss. The healthy fats in boiled peanuts also slow digestion and stabilize blood sugar levels, further assisting in weight management.
Lower Diabetes Risk
Peanuts have a low glycemic index, meaning they do not cause a rapid spike in blood sugar levels. Research indicates that eating peanuts may lower the risk of type 2 diabetes, particularly in women at risk of the disease.
Reduce Inflammation
Peanuts are rich in antioxidants, unsaturated fats, and fiber, all of which can help reduce inflammation throughout the body. Studies have shown that people who consume peanuts and peanut butter have lower markers of inflammation, such as C-reactive protein and interleukin-6.
Cancer Prevention
The high antioxidant content and phytochemicals in peanuts may offer protection against cancer. Resveratrol, a plant chemical found in peanuts, has shown potential benefits against various types of cancer. Regular consumption of peanuts and peanut butter may also lower the risk of gastric noncardia adenocarcinoma, a type of stomach cancer, especially in older adults.
Alzheimer's Prevention
Peanuts contain resveratrol, vitamin E, and niacin, all of which may protect against Alzheimer's disease. Vitamin E from food sources like peanuts, rather than supplements, has been linked to cognitive benefits. Studies have shown that older adults who regularly consume nuts, including peanuts, have higher mental function scores compared to those who do not.

Gallbladder Health
Eating peanuts may also protect the gallbladder, the organ responsible for producing and releasing bile. Regular peanut consumption has been associated with a lower likelihood of needing gallbladder surgery due to gallstones, particularly in women. Research also suggests that men who frequently eat peanuts may have a reduced risk of developing gallstones.
Good Source of Energy
Peanuts are energy-dense, providing a significant amount of energy. They are considered one of the best and most affordable sources of protein.
Boiled vs. Roasted Peanuts
While both boiled and roasted peanuts offer health benefits, there are some key differences:
- Antioxidant Content: Boiling peanuts increases their antioxidant content compared to raw or roasted peanuts.
- Fat Content: Boiled peanuts generally have lower fat content than roasted peanuts due to the absence of added oils in the cooking process.
- Calories: Boiled peanuts usually contain fewer calories than roasted peanuts.
- Texture: Boiled peanuts are softer and retain more natural moisture, while roasted peanuts are crispier and have a higher oil content.
- Flavor: Roasting can enhance the taste and aroma of peanuts, making them more palatable to some individuals.
A study comparing the effects of boiling versus roasting on peanuts found that boiling increased the fat content to 54.47%, diluted or reduced sugar content to an undetectable level, noticeably changed the contents of poly/monounsaturated fatty acids, and significantly decreased the content of free amino acid (FAA, 1.05 mg/g peanuts) in peanuts. Roasting simply decreased the contents of sugar and FAA to 2.78 and 1.82 mg/g peanuts, respectively. Compared with roasting, boiling had more discernible effects on fatty acids and FAAs. Roasting induced a relatively small effect on nutritional components and gave peanuts a richer taste and stronger aroma than boiling; therefore, roasting is an ideal peanut processing method.
Boiled Peanuts and Weight Loss
Boiled peanuts can be a valuable addition to a weight loss plan due to their high protein and fiber content, which promotes satiety. The healthy fats in boiled peanuts also contribute to slower digestion and stable blood sugar levels, aiding in weight management.

Potential Downsides of Eating Boiled Peanuts
While boiled peanuts offer numerous health benefits, there are a few potential downsides to consider:
Allergies
Peanuts are a major allergen and can cause serious food reactions in some individuals. Symptoms of a mild peanut allergy include itchy hives, nausea, and swelling of the face. A severe peanut allergy can cause anaphylaxis, a life-threatening reaction with symptoms such as trouble breathing, changes in alertness, nausea, vomiting, seizures, chest pain, swelling of the tongue, face, or lips, extreme drowsiness, dizziness, confusion, or lightheadedness.
Digestive Problems
Even if you are not allergic, eating too many peanuts can cause digestive problems like diarrhea, belly cramps, nausea, or vomiting. To prevent digestive issues, limit your intake to the recommended serving size of 1 ounce (about 35 peanuts) per day.
Food Poisoning
Peanuts can sometimes be contaminated by harmful germs, such as Salmonella bacteria or Aspergillus flavus, a fungus that releases a deadly toxin. These contaminants can cause food poisoning with symptoms like diarrhea, stomach pain, fever, and weight loss. To minimize the risk of food poisoning, purchase peanut products from reputable sources and ensure they have not been recalled.
High Sodium Content
Commercially prepared boiled peanuts, especially canned or heavily salted varieties, can be high in sodium. Excessive sodium intake can lead to high blood pressure and other health problems. It is important to consume boiled peanuts in moderation and choose varieties with lower sodium content.
How to Incorporate Boiled Peanuts into Your Diet
Boiled peanuts can be enjoyed as a snack on their own or incorporated into various dishes:
- Snack: Enjoy a small serving of boiled peanuts as a satisfying and nutritious snack.
- Salads: Add boiled peanuts to salads for a boost of protein and fiber.
- Side Dish: Serve boiled peanuts as a side dish with meals.
- Soups and Stews: Incorporate boiled peanuts into soups and stews for added texture and flavor.
