As you can see nutritional value of peanuts vs walnuts in the above table, belonging to the same food group “nuts”, they provide different proportions of nutrients. Peanuts are comparatively higher in protein, carbohydrates, and fiber, while walnuts are high in calories, have higher fat content, especially have healthy fats and are lower in carbohydrates.2 Let’s understand how each of these can be beneficial for your child.

Walnut Benefits for Kids

Walnuts have higher fat content and especially contain α-Linolenic acid, which is an essential fatty acid that your child needs. Essential fatty acids mean, this cannot be synthesized by your child’s body and need to be taken from food.

Walnuts nutrition is special, as α-Linolenic acid belongs to the healthy fats category, important for your child’s brain, eyes, and nervous system development.4 Now you know why walnut is also called the “brain food”. Walnuts nutrition also stands out due to their high vitamin E content.5 Vitamin E is a powerful antioxidant that protects your child’s body, especially brain cells against damage from harmful molecules such as reactive oxygen species.4 Walnuts are also calorie-dense as compared to peanuts, fuelling your child with the required energy for studying, playing, and being active all day. Walnuts nutrition is also special because it has lower carbohydrate content. This helps prevent spikes in glucose levels and is especially beneficial for children with obesity and diabetes.3 These are exceptional walnut benefits for kids.

Peanuts Nutrition and Benefits for Kids

Peanuts have higher protein and fiber content than walnuts. Protein in peanuts will help your child meet daily protein requirements, which is important for muscle, bone, teeth, and overall development. So, “P” in peanuts stands for protein in peanuts.

Higher fiber content is another reason why peanuts nutrition is distinct. Fiber supports your child’s gut health, which is important for preventing constipation, aids in the absorption of nutrients supporting adequate growth.6

Which One Should You Choose?

This knowledge of peanuts nutrition and walnuts nutrition must have left you confused -walnuts vs peanuts, which one to choose? It is impossible to answer this with a single yes or no to this question.

Both walnuts and peanuts provide different and important nutrients for your child. Which one to choose and how much may vary depending on your child’s current food intake, their health status, and their nutrient requirements. If your child does not eat enough protein and fiber sources, then more focus on the inclusion of peanuts and other protein and fiber sources can be made to meet those requirements. Peanuts nutrition is an amazing combination of protein and fiber, as not all protein sources are high in fiber too. However, all children need healthy fats for brain development, so inclusion of healthy fats from walnuts and other healthy fat food sources, should not be ignored either and must be included as required in daily diet. Peanuts are also comparatively cheaper than other protein sources and come in as a good vegetarian source of protein. As we say, variety is the spice of life, similarly, food diversity, i.e. including a variety of foods from different food groups regularly, is important to get all the nutrients your child needs to flourish. No single food is complete and enough on its own to provide all nutrients.
