Peanut butter, also known as peanut paste, is a preparation obtained from roasted peanuts, ground until they form a smooth paste.

To get all the benefits of this peanut, it is advisable to choose 100% natural peanut butter.

In addition, it is naturally gluten-free, which can suit many diets.

And nutritional value?

The nutritional value of peanut butter per 100g provides approximately:

• Energy: Between 607 kcal and 637 kcal

• Proteins: Between 27g and 29g
• Dietary fiber: 7.8g and 8.6g
• Salt: Between 0g and 0.02g

It can be easily integrated into a balanced diet, as long as quantities are kept reasonable.

What to do with peanut butter?

Peanut butter is not just for spreading on toast. It is a versatile ingredient that can advantageously replace several common products, while providing quality nutrients.

• For baking: It can replace butter or oil, providing softness and good structure to the dough, with unsaturated fats. It can be used in equivalent proportions, while taking into account its more pronounced aroma.
• For snacks: It is a good alternative to animal protein sources. In a smoothie, a bowl cake, or energy balls, it provides plant proteins, fiber, and a good dose of energy.
• For savory dishes: It can replace cream- or cheese-based sauces. Mixed with a little water, lemon, and spices, it becomes a creamy sauce for vegetable dishes, noodles, or wraps.
• For desserts: It can sometimes reduce the amount of sugar thanks to its naturally sweet flavor, especially when combined with fruits like banana.
