Cardiologist Warns Against This Popular High-Protein Snack

That familiar afternoon energy slump often sends us searching for something to snack on. And with high-protein foods taking over social media, many people are reaching for snacks that promise to keep them full, boost their energy, and support their fitness goals. But according to one cardiologist, a popular protein-rich snack may not be as healthy as it seems.

Supermarket shelves are packed with products advertising high protein content, convenient nutrition, and ingredients that appear healthier than traditional snacks. Fitness influencers frequently recommend them for muscle recovery, while others promote protein-rich foods as a way to manage hunger and support weight loss.

Although protein is essential for maintaining muscle, repairing tissues, and helping us feel satisfied after eating, the amount of protein in a product doesn't tell the whole story. Some convenient protein snacks also contain significant amounts of sodium, saturated fat, and added sugar, which can undermine their potential health benefits.

The High-Protein Snack That May Be Less Healthy Than You Think

Cardiologist Dr. Lars Sondergaard warns that one particularly popular snack deserves a closer look: beef jerky.

"I think a surprising snack that people may overdo is dried jerky. While it's marketed as a protein-rich option to take on the go — and that's partly true — it's worth pointing out the nutritional trade-offs it carries," he explains.

Beef jerky is often promoted as a convenient alternative to chips, cookies, and other processed snacks. It's portable, doesn't usually require refrigeration, and provides a substantial amount of protein in a relatively small serving.

However, the drying, seasoning, and preservation process can leave some varieties with high sodium levels. Certain products also contain added sugar and saturated fat, making it important to look beyond the protein content advertised on the front of the package.

Why Too Much Sodium and Saturated Fat Can Affect Your Heart

The main concern is the combination of sodium and saturated fat, particularly when these are consumed regularly as part of an already high-sodium or high-saturated-fat diet.

Excess sodium can contribute to fluid retention and elevated blood pressure, increasing the strain on the heart and blood vessels over time. High blood pressure is a major risk factor for heart disease and stroke.

Saturated fat can also affect cardiovascular health by raising levels of low-density lipoprotein (LDL), commonly known as "bad" cholesterol.

As Dr. Sondergaard explains, "Saturated fat raises levels of low-density lipoprotein, also known as 'bad' cholesterol — a leading cause of heart disease."

When LDL cholesterol levels remain elevated, cholesterol can accumulate in the walls of arteries, contributing to plaque formation and increasing the risk of cardiovascular problems.

This doesn't mean that eating beef jerky occasionally will harm your heart, or that every variety has the same nutritional profile. However, regularly choosing high-sodium, high-saturated-fat products simply because they're labeled "high protein" may not be the healthiest approach.

What Should You Eat Instead?

Rather than relying on processed protein snacks, Dr. Sondergaard recommends choosing foods that provide valuable nutrients without excessive amounts of salt or saturated fat.

Unsalted nuts are a convenient option, offering protein, fiber, and heart-healthy unsaturated fats. Fresh fruit provides fiber, vitamins, and natural carbohydrates, making it a refreshing choice when afternoon hunger strikes. Fish rich in omega-3 fatty acids can also be a valuable part of a heart-healthy diet.

If you enjoy beef jerky, there's no need to automatically eliminate it from your diet. Instead, check the nutrition label, compare sodium and saturated fat levels between brands, and pay attention to serving sizes.

Ultimately, a snack's health benefits depend on more than its protein content. Choosing foods based on their overall nutritional value, rather than a single number on the package, can help you make better decisions for your heart and long-term health.
