Peanut Butter: Cheap, High-Protein Health Food?

Peanut Butter: Cheap, High-Protein Health Food?

A spread that costs little, packs nearly 50% protein, and tastes great? It sounds too good to be true, yet enthusiasts defend it with nutritional charts in hand. Peanut butter, long dismissed for its fatty fruta, is making a quiet but firm comeback among those seeking dense nutrition without breaking the bank. The numbers support this claim: 28% protein, 52% fat (only 9% saturated), just 15% carbohydrates (of which only 4% are sugars), and nearly 10% fiber. All this for a price hovering around €2-3 per jar.

Nutritional Profile: Fat Trap or Superfood?

The first shock is the fat content—52%—which scares anyone who has heard that fat makes you gain weight. But here, the devil is in the details. Most of it consists of monounsaturated fats (oleic acid, the same found in olive oil) and polyunsaturated fats (linoleic acid), with minimal saturated fat presence. Studies suggest this composition helps balance cholesterol levels. Additionally, it provides minerals such as phosphorus, zinc, magnesium, and potassium, along with B vitamins. It is no surprise that it remains a staple for athletes and vegans: its caloric density (600 kcal/100 g) makes it an energy boost, but also a bomb if portion sizes are not controlled. A slice of toast with a generous layer can exceed 500 kcal, enough to cover a quarter of an average adult's daily needs.

The Price Factor: Protein Value

Here lies the surprise. Peanut butter competes directly with eggs or legumes in cost per gram of protein. At about €2.50 for a 350-gram jar, every 100 grams costs roughly €0.71, offering 28 grams of protein. If you opt for the defatted powder version—a 200-gram bag for less than €3—the protein content skyrockets to 49%, with only 12.6% fat. This powder, designed for yogurts, smoothies, or baking, yields about 10 servings of 20 grams, making it the cheapest protein supplement in the supermarket, even beating eggs when calculating price per gram of protein.

Textures, Brands, and Processing Traps

Not all creams are created equal. "Natural" versions contain only ground roasted peanuts, with no added oils (such as palm oil), salt, or sugar. Brands like Carrefour, Dia, or Alcampo offer options for under €3. There is also the crunchy range, with nut pieces, preferred by some for texture. However, some distrust processed foods: grinding peanuts releases oils, making the fat more available and, according to some, increasing absorption estimulante ilegal. Others argue that homemade peanut butter—made using a blender from raw peanuts—allows control over freshness and avoids additives. The debate on whether industrial crushing is a step toward ultra-processed food remains open.

Does It Make You Gain Weight? Balance Is in the Dose

The million-dollar question. With 600 kcal/100 g, anyone eating half a jar in one sitting will face problems. But defenders argue that its satiating power—comparable to hard-boiled eggs—curbs hunger for hours, reducing total intake. Those who use it for breakfast or snacks accompanied by fruit (especially blueberry jam, a combination some describe as addictive) claim they hold out until lunch without snacking. The risk lies not in the food itself, but in the lack of control. As with almost everything.

In summary: peanut butter is a cheap, dense, and versatile nutritional wildcard, but its high caloric content demands moderation. It is neither a panacea nor a demon. It is simply a product that deserves a place in your pantry if used wisely. Or, as a veteran food analyst ironically notes: "If you eat four slices of toast, forget about eating for the rest of the day. And that, well managed, is not a flaw."
