The Core Nutritional Profile of a 20g Serving
Peanuts, often mistaken for nuts, are actually legumes, but their nutritional composition is very similar to tree nuts. A 20g portion is a convenient way to add a potent mix of protein, fiber, and healthy fats to your daily intake. The exact values can vary slightly depending on preparation, with raw peanuts having a different profile than oil-roasted and salted versions.
For a standard 20g serving of raw peanuts (approximately 20 shelled peanuts), here's a detailed breakdown of what you can expect:
- Calories: Around 113 kcal. This makes them a calorie-dense snack that provides a quick and lasting energy boost.
 - Protein: About 5 grams. Peanuts are an excellent plant-based protein source, crucial for muscle repair and growth.
 - Fats: Approximately 10 grams. The majority of this fat content is made up of heart-healthy monounsaturated and polyunsaturated fats, which can help lower bad cholesterol (LDL).
 - Carbohydrates: Roughly 3 grams. With a low glycemic index, peanuts do not cause a rapid spike in blood sugar levels.
 - Dietary Fiber: About 2 grams. Fiber is essential for digestive health and helps promote feelings of fullness.
 
Vitamins and Minerals Packed into 20g
Beyond the basic macronutrients, a small serving of peanuts also provides a variety of important micronutrients.
A 20g serving of peanuts contains:
- Niacin (Vitamin B3): Contributes to energy metabolism and brain function.
 - Folate (Vitamin B9): Vital for cell growth and DNA synthesis.
 - Vitamin E: A powerful antioxidant that protects cells from damage.
 - Magnesium: Important for muscle and nerve function, blood sugar control, and blood pressure regulation.
 - Manganese: Plays a role in bone formation and metabolism.
 - Phosphorus: Works with calcium to build strong bones and teeth.
 
Health Benefits of This Small Serving
Regularly including a modest portion of peanuts in your diet can offer several health advantages:
- Supports Heart Health: The combination of monounsaturated fats, polyunsaturated fats, and antioxidants like resveratrol contributes to reducing the risk of heart disease.
 - Aids in Weight Management: The high protein, fiber, and healthy fat content helps increase satiety, reducing overall food intake and preventing overeating.
 - Helps Control Blood Sugar: With a low glycemic index, peanuts can help manage blood sugar levels and are a great snack option for people with diabetes.
 - Provides Antioxidants: Peanuts are rich in antioxidants that fight oxidative stress and protect against chronic diseases.
