The peanut, scientifically known as Arachis Hypogaea, is a product that has been the protagonist in many dishes for years, especially spread on bread in the form of peanut butter. 

But, even though we have already welcomed this grain into our homes and peanut butter consumption is widespread around the world, it is common to ask: are peanuts healthy? Why is peanut allergy so common if it’s considered a healthy food?

The Health Reporter team tells you all about this food and its nutritional value. Join us to discover 10 health benefits of peanuts.

What Is a Peanut?

Peanut is a member of the bean and lentil family, although it is commercially classified as a nut, along with almonds and walnuts. Overall, peanuts are high in monounsaturated fats and a rich source of vegetable protein.

They are great for athletes due to their energy contribution and are recommended during pregnancy because of their folic acid content. In addition, eating peanuts combined with cereals forms a complete protein with a whole chain of amino acids, making it ideal for plant-based and vegan diets.

Are Peanuts Healthy?

The peanut is a healthy grain containing all 3 macronutrients, with good fats being the most relevant, followed by high-quality proteins and complex carbohydrates.

Even though peanuts are one of the most common causes of food allergy, they have great nutritional value and aid in weight loss.

Peanuts are also suitable for high-fat, low-carbohydrate diets for weight loss, such as the ketogenic diet.

High in calories and fats

Peanuts provide mainly fat, which makes them a high-calorie food that should be consumed in moderation.

High in protein

Peanuts have the same amount of protein as tuna or eggs per 100g, although eating more than 40g per serving is not suggested due to the fat content. For a complete protein, combine a tiny amount of peanuts with a portion of cereals like rice or oatmeal, which include carbs.

High in carbohydrates

A 28g serving of peanuts contains only ~4g of carbohydrates, but it is very easy to exceed this amount as you could eat more without realizing it, especially with peanut butter.

If you are on a low-carb diet, you should be aware that peanuts add carbs to your daily requirement and should be consumed in moderation.

Rich in vitamins and minerals

Peanuts have a very diverse vitamin profile that includes vitamins B3 and B6 essential for the health of the nervous system. They also have minerals such as potassium, copper, and magnesium, which are also important for maintaining neurological functions.

A Word From Our Nutritionist

Peanuts are not only a nutritious food, they’re also valuable for the planet, as, according to the National Peanut Board, the cultivation of peanuts uses minimal water, and everything from the root to the shell is used.

It is important to include peanuts in the daily diet from an early age since it has been described in some studies that children exposed to raw peanuts from 1 year of age develop fewer peanut allergies than those who rarely ate peanuts or rarely ate nuts in general.

Eating peanuts is beneficial as a protective agent of the cardiovascular system due to their richness in monounsaturated and polyunsaturated fatty acids.

Eating peanut butter and unsalted peanuts can help improve heart health and nervous system health.
