What are the macros of 100g of peanuts?

4 min read

According to the USDA, a 100g serving of raw peanuts contains about 567 calories. But beyond the caloric count, what are the macros of 100g of peanuts? This comprehensive breakdown reveals how these versatile legumes fit into various dietary plans, from low-carb to high-protein.

Quick Summary

A 100g serving of raw peanuts contains approximately 26g of protein, 49g of fat, and 16g of carbs, with minor variations depending on preparation. The fat is predominantly heart-healthy unsaturated, contributing to the calorie density. Peanuts also offer significant dietary fiber and various micronutrients.

Key Points

  • High in Healthy Fats: 100g of peanuts contains around 49-50g of fat, primarily heart-healthy unsaturated types.

  • Excellent Source of Protein: A 100g serving of raw peanuts provides approximately 26g of plant-based protein.

  • Low in Net Carbs: With about 16-21g of total carbs and a high fiber content (8-9g), peanuts have a low glycemic index, making them suitable for low-carb diets.

  • Slightly Higher Calories When Roasted: Dry-roasted peanuts (approx. 587 kcal/100g) have a marginally higher calorie count than raw peanuts (approx. 567 kcal/100g) due to moisture loss.

  • Rich in Micronutrients: Peanuts are packed with vitamins and minerals like biotin, copper, niacin, folate, and magnesium.

  • Promotes Satiety: The combination of protein, fat, and fiber in peanuts helps promote a feeling of fullness, which can assist in weight management.

  • Versatile and Convenient: Peanuts can be enjoyed in various forms, including raw, roasted, or as peanut butter, providing a flexible way to add nutrients to your diet.

Peanuts are a popular and affordable food that offers a powerful nutritional punch, though their macronutrient composition can vary slightly based on how they are prepared. Understanding the precise macronutrient profile is key for anyone tracking their intake for fitness, weight management, or general health. Here, we delve into the details of what makes up the macros of 100g of peanuts, comparing raw versus roasted varieties and discussing their overall health benefits.

The Macronutrient Profile of 100g of Raw Peanuts

Raw peanuts, which are technically legumes but are considered nuts in culinary practice, provide a concentrated source of energy from healthy fats, protein, and complex carbohydrates. The following is a general breakdown of the macros found in a 100g serving of raw peanuts:

  • Protein: Approximately 26g. This makes peanuts an excellent source of plant-based protein, surpassing many other nuts in content.
  • Fat: Around 49g. The majority of this is heart-healthy monounsaturated and polyunsaturated fat, contributing significantly to the overall calorie count.
  • Carbohydrates: Roughly 16g. A notable portion of this consists of dietary fiber, making the net carb count relatively low.
  • Dietary Fiber: Approximately 9g. This aids in digestion and helps promote a feeling of fullness.

The Impact of Roasting on Peanut Macros

Roasting is a common preparation method that changes the texture and flavor of peanuts. While the macronutrient profile remains largely similar, there are subtle differences to be aware of:

  • Calories: Roasted peanuts often have a slightly higher calorie count (around 587 kcal per 100g) compared to raw (567 kcal). This is because the roasting process removes some moisture, concentrating the nutrients.
  • Protein: The protein content remains quite stable. For dry-roasted peanuts, you can expect around 24g of protein per 100g, a minimal change from the raw version.
  • Fat: Fat content is also very similar, with a slight increase in dry-roasted peanuts (around 50g per 100g) due to the moisture loss. The fat composition of healthy monounsaturated and polyunsaturated fats is maintained.
  • Carbohydrates and Fiber: Carbohydrates may also increase slightly (around 21g), but the fiber content stays high (around 8g), keeping the net carbs manageable for those on lower-carb diets.

Comparison: Raw vs. Roasted Peanuts

Macronutrient (per 100g) Raw Peanuts Dry-Roasted Peanuts (unsalted)
Calories ~567 kcal ~587 kcal
Protein ~26g ~24g
Total Fat ~49g ~50g
Total Carbohydrates ~16g ~21g
Dietary Fiber ~9g ~8g
Net Carbohydrates ~7g ~13g

The Micronutrient Power of Peanuts

Beyond their macros, peanuts are a fantastic source of essential vitamins and minerals. For a 100g serving, you can expect a rich supply of several micronutrients:

  • Biotin: An excellent dietary source, important for metabolic health.
  • Copper: Essential for heart health, as a copper deficiency can have adverse effects.
  • Niacin (Vitamin B3): Plays a vital role in energy production and is linked to a reduced risk of heart disease.
  • Folate (Vitamin B9): Crucial for proper cell division and especially important during pregnancy.
  • Magnesium: A key mineral involved in over 300 biochemical reactions in the body, including blood sugar control and muscle function.
  • Manganese: An important trace element for bone development and metabolism.

How to Incorporate Peanuts into a Healthy Diet

Peanuts' high-fat and moderate-protein content can be effectively integrated into various diets. Their high satiety value helps with weight management, despite their calorie density. You can enjoy them in several ways:

  • As a quick snack: A small handful of unsalted, dry-roasted peanuts can curb hunger and provide a boost of energy.
  • In salads and stir-fries: Chopped peanuts add a satisfying crunch and nutty flavor.
  • In sauces: Peanut butter is a key ingredient in many sauces for Asian-inspired dishes.
  • As a post-workout recovery food: The protein content helps with muscle repair, while the carbs replenish glycogen stores.

The Healthy Fat Profile of Peanuts

One of the most notable aspects of the macro profile of 100g of peanuts is the fat composition. The majority of the fat is unsaturated, specifically a beneficial blend of monounsaturated and polyunsaturated fats. These fats are widely recognized for their heart-healthy properties, including helping to lower bad (LDL) cholesterol levels.

Conclusion: A Macro-Rich, Nutrient-Dense Food

Ultimately, the macros of 100g of peanuts confirm their status as a nutrient-dense food. With a high protein and healthy fat content, along with significant fiber, they offer a filling and sustained source of energy. While they are calorie-dense, their nutritional benefits, including a wide range of vitamins and minerals, make them a valuable addition to a balanced diet when consumed in moderation. The subtle differences between raw and roasted peanuts are minor, allowing for flexibility in preparation while still reaping the health rewards. For more information on dietary choices, you might consult resources like the American Heart Association (AHA) guidelines on fats. For those managing specific dietary needs, such as a low-carb diet, monitoring net carbs is crucial, but peanuts remain a low-glycemic option.
