A Nutritional Profile Packed with Goodness
Despite their small size, peanuts are a nutritional powerhouse, offering a rich profile of macronutrients and micronutrients essential for overall health. A typical 1-ounce (28g) serving of raw peanuts contains approximately 161 calories, and provides protein, healthy fats, and fiber. Peanuts are a good source of plant-based protein.
The Role of Healthy Fats
Peanuts contain predominantly mono- and polyunsaturated fats, which are considered heart-healthy. These fats can help lower bad cholesterol (LDL) and support cardiovascular wellness. The main fats are oleic and linoleic acids.
Essential Vitamins and Minerals
Peanuts are a source of various vitamins and minerals, including Biotin, Copper, Niacin (Vitamin B3), Folate (Vitamin B9), Manganese, Vitamin E, Thiamine (Vitamin B1), Phosphorus, and Magnesium. These nutrients support functions ranging from energy conversion to red blood cell formation and antioxidant protection.
Potent Antioxidants and Phytonutrients
Peanuts contain bioactive plant compounds and antioxidants, which are particularly concentrated in the skin. Key compounds include p-Coumaric acid, Resveratrol, Isoflavones, and Phytosterols. Resveratrol is known for its antioxidant properties, while phytosterols can help limit cholesterol absorption.
Peanuts for Weight Management
Despite being calorie-dense, peanuts can play a role in weight management due to their ability to increase feelings of fullness.
- High Satiety Value: Protein, fats, and fiber contribute to a feeling of fullness, which may reduce snacking and overall calorie intake.
- Reduced Calorie Absorption: Some research suggests that not all fat from whole peanuts is fully absorbed if not chewed thoroughly.
- Boosted Metabolism: The nutrient composition may also slightly increase calorie burning.
Supporting Cardiovascular and Brain Health
Regular peanut consumption is associated with a reduced risk of heart disease and stroke due to their healthy fats, fiber, and antioxidants. Nutrients in peanuts like niacin, vitamin E, and resveratrol may also support brain health and potentially protect against cognitive decline. They may also help reduce the risk of gallstones.

| Calories | 567 kcal | 579 kcal |
| Primary Benefits | High in protein, low glycemic index, rich in folate and niacin. | Rich in Vitamin E, magnesium, and calcium. |
| Antioxidant Content | High in resveratrol and p-Coumaric acid. | Contains flavonoids and other plant compounds. |
Conclusion
Peanuts offer numerous benefits, including supporting heart and brain health, aiding weight management, and providing essential nutrients and antioxidants. Incorporating unsalted, unprocessed peanuts into a balanced diet in moderation can contribute to overall well-being. For detailed nutrition information, consult resources like the USDA.
