Unveiling the Real Deal About Protein Bars: Advertised Proteins May Not Deliver as Promised
Snacking Smarter: Navigating the Protein Bar Craze

In our fast-paced world, protein bars have become a staple for quick nutrition on-the-go. But are these popular snacks living up to their reputations as health powerhouses? A recent study raises some interesting questions about their true benefits. Let's dive in and find out whether protein bars can meet their protein promise without falling short on other essential nutrients.
The research, conducted by scientists using data from OpenFoodFacts.org, analyzed over 1,600 popular protein bar varieties, evaluating their actual protein absorption rates.
To test their findings, four samples of popular bars were chosen:
- A bar with exclusively plant-based proteins (pea and rice).
- A bar with only animal-based proteins (dairy-based).
- A mixed animal-based option (milk and eggs) plus a plant-based component (soy protein).
- A combined bar with both animal (milk and collagen) and plant-based (soy) proteins.
The researchers examined protein absorption using traditional and modern methods.
Surprise, surprise! Not all the "healthy" bar content is absorbed equally well.
Firstly, a high protein percentage in a bar does not guarantee that this protein will be well absorbed by our bodies. Although most bars (around 81%) contained sufficient protein to meet the European Union's requirements (to be labeled as "high protein"), the actual benefits were far from ideal. Most products showed a low bioavailability of essential amino acids that our bodies require. This means we can't obtain them from the bar, even if we eat it.
Secondly, the source of protein matters.
Animal protein products showed significantly better absorbability, especially milk-based bars (absorbed around 61%), compared to purely plant-based products (absorbed at only 26%).
Thirdly, the role of collagen gets a reality check.
Many manufacturers add collagen to boost overall protein content, but collagen has a low level of essential amino acids crucial for the body. Inclusion of collagen in a product makes the protein practically unsuitable for complete tissue recovery (less than 10% of protein is absorbed from a bar).
Fourthly, extra ingredients hinder protein absorption in bars.
Additives of fats, carbohydrates, and dietary fiber significantly reduce the availability of beneficial amino acids. Despite high protein levels, such bars lose their appeal as a desirable source of nutrition.
So, how can you choose a truly beneficial protein bar?
Ingredient Investigation: Prioritize bars with animal protein, like whey or milk, for better absorption. If you're plant-forward, try products with blended plant ingredients (such as a combination of peas and rice) to compensate for the deficiency of certain amino acids.
Collagen Caution: Keep an eye out for collagen; while it might boost protein content, it provides only a limited range of essential amino acids and often offers little benefit for muscle growth or overall body condition.
Minimal Additives: Aim for simple compositions with minimal sugar, artificial additives, and complex fats for efficient protein absorption.
Food First: Remember that while protein bars are convenient, they should complement balanced nutrition rather than replace meals.opt for protein-rich whole foods like poultry meat, fish, beans, or tofu for nutrition that goes beyond a bar.
🎓 Dr. Zuhra Pavlova, a senior researcher at the Faculty of Fundamental Medicine, M.V. Lomonosov Moscow State University, offers her expert insights:
- Smart Snacking: Look for bars with less sugar, saturated fats, and added salt. Opt for options rich in fiber and micronutrients. Don't let marketing claims about protein deceive you; these don't guarantee true nutrition.
🌟 Be mindful of replacing actual meals with bars, especially for those with diabetes, excess weight, or metabolic disorders.
🥘 While protein bars can be handy for emergencies, always prioritize proper balanced meals for optimal nutrition.
🥩 A Path to Lean Protein: Alexei Moskalyov, an expert scientist-biologist and expert in technologies against aging and for longevity, provides his tips on getting lean protein:
- Choose wisely: Instead of fatty meat or cheese, pick lean cuts like skinless chicken, turkey, fish, or tofu if going plant-based. Opt for options with fewer calories, like 100g of chicken breast has approximately 110 kcal, while fatty pork already has 250 kcal.
- Cook smart: Choose healthier preparation methods such as baking, boiling, or stewing instead of frying. Reduce oil quantity from your recipes. While some oils are healthy, a tablespoon typically adds 120 calories.
🚫 Definitely skip store-bought industrial sauces and dressings, as they add unnecessary calories. Choose lighter options like lemon juice, mustard, or plain unsweetened yogurt to dress your meals.
- The study showed that animal protein products, particularly milk-based bars, have a higher protein absorbability rate than purely plant-based products.
- When looking for a beneficial protein bar, it is recommended to prioritize bars with animal protein like whey or milk for better absorption, or products with blended plant ingredients for more complete amino acid profiles.
- It's important to be mindful of extra ingredients in protein bars, as additives of fats, carbohydrates, and dietary fiber can significantly reduce the availability of beneficial amino acids.
