What Is Nutritional Value of Peanuts?: By Geetanjali Khangembam

Peanuts look like a simple, everyday snack.

Nutritionally, they are far more powerful than most people assume.

If you have ever questioned whether peanuts are actually healthy or just another high-calorie food, you are not alone.

There is a lot of confusion around fats, protein, and weight gain, and peanuts often get misunderstood in that conversation.The reality is that peanuts are one of the most affordable sources of plant-based protein and healthy fats compared to more expensive nuts like almonds and cashews.

At the same time, their calorie density raises a practical question.

Should you be eating them every day?In this guide, you will understand the nutritional value of peanuts per 100g, what makes them nutritionally significant and whether they deserve a place in your daily diet.

Nutritional Value of Peanuts Per 100g

So, what exactly do you get from 100 grams of peanuts? The table below gives you a clear, quick snapshot of their nutritional profile.NutrientValue per 100gCalories567 kcalProtein25-26 gTotal Fat49 gCarbohydrates16 gDietary Fibre8-9 gSugars4-5 gTakeaway: With around 25 g of protein per 100 g, peanuts offer a protein content comparable to many commercial protein bars, but at a significantly lower cost and with fewer additives.

Nutritional Composition of Peanuts (Macros and Micronutrients)

Peanuts are often evaluated based on calories alone, but their nutritional value depends on what those calories consist of.

A significant portion comes from protein, healthy fats, and essential micronutrients that actively support body functions, rather than just adding energy.Protein ContentPeanuts provide around 25 g of protein per 100 g, which makes them one of the more practical plant-based protein sources.

This is particularly useful in diets where protein intake is often lower than required.

Unlike many snacks that are mostly carbohydrates, peanuts contribute to daily protein needs, supporting muscle repair, satiety, and overall metabolic function. Healthy FatsPeanuts' composition is mainly fat, but the type of fat is what makes the difference.

Peanuts are rich in monounsaturated and polyunsaturated fats, which are also found in foods such as olive oil.

These fats are associated with improved heart health when they replace saturated fats in the diet.

Peanuts should be seen as a source of functional fats that provide sustained energy and aid in nutrient absorption, rather than just a high-fat food.Low Glycaemic IndexPeanuts have a low glycaemic index, which means they release energy slowly rather than causing rapid spikes in blood sugar levels.
