What are protein bars exactly?

Protein bars are supplements designed to increase the protein intake in a diet, both in quantity and quality. They contain proteins of high biological value that can come from milk (whey protein, milk protein isolates and concentrates, calcium caseinate), collagen, soybeans, seeds or peas.

Proteins are chains of amino acids, they are considered to have a high biological value when it contains all (or almost all) of the amino acids essential to humans. If any of these amino acids are missing, the proteins that will be used to repair or build body tissues, including muscle, cannot be synthesized.

Proteins are mixed with other macronutrients, such as fats, carbohydrates, and dietary fibres and presented in the form of bars, composed in a way that creates a satisfying flavour. The quality and proportion of fats and sugars combined with the amount of protein will in turn determine the nutritional value of the protein bar.

What are the typical ingredients of protein bars?

Most protein bars belong to the processed food category and their components are far from natural. However, vegan bars are usually made with 100% organic ingredients. Protein bars can carry the following compounds:

  • Proteins: Protein bars incorporate high quality animal and vegetable proteins to ensure the proper supply of all the amino acids that are essential for optimal human health (tryptophan, threonine, phenylalanine, methionine, leucine, isoleucine, valine and lysine).
  • Source or proteins: The protein sources are Whey​ protein (whey), milk protein (concentrate or isolate), calcium caseinate (milk), hydrolyzed collagen, soy protein, pea protein, seed protein (hemp, amaranth), among others.
  • Carbohydrates: Sometimes, simple sugars are used as sweetening components of protein bars. In the best quality bars, polyols (alcohol sugars) are utilized. Polyols do not damage teeth or raise blood glucose (blood sugar) levels. In addition, they provide only 2.4 calories per gram, while simple sugars provide 4 calories per gram.
  • Fats: These are mainly​ present in Protein bar coatings, which are usually made of dark or white chocolate. The problem is that more often than not, saturated and hydrogenated fats (trans fats) are used to make them more appealing and tasty, this however, has a noticeable negative impact on its nutritional quality.
  • Food fibre: This component is extremely important because it increases the satiety value of the protein bar, which helps suppress appetite. In addition, fibre slows the absorption of sugars from foods and, consequently, prevents blood glucose peaks in people with diabetes or insulin resistance.
  • Flavours and colourings: In natural and organic bars, foods with an intense flavour and aroma (e.g. cinnamon or cocoa) are usually added to improve the organoleptic characteristics of these products. However, manufacturers of processed protein bars sometimes abuse artificial additives in an attempt to boost their flavour.

The table below is a visual representation of the possible ingredients in these bars and their nutritional value and health benefits:

Ingredients Healthy Unhealthy
Protein Whey protein, milk protein concentrate (whey + casein), milk protein isolate, calcium caseinate, egg white protein, hydrolyzed collagen, legume protein (peas), whole grain protein (brown rice), seed protein (amaranth, quinoa, hemp). Watch out for soy protein! Most soybeans are transgenic and chemical pesticides and fertilizers are used in their cultivation.
Carbohydrates (sweeteners) Sucralose, isomaltose, sorbitol, coconut nectar, xylitol, Maltitol. High fructose corn syrup, sucrose (common sugar), glucose.
Fats Coconut oil, olive oil, cocoa butter. Palm and palm kernel oil. Hydrogenated oils in general.
Other ingredients to provide flavour and aroma Natural apple aroma, natural vanilla, cocoa, bitter chocolate, cinnamon, nuts, dried fruits, seeds and essential oils. Milk chocolate, white chocolate, sweets, jellies and processed sugars and preservatives.

Are all protein bars equally healthy?

As you can see from the table above, there are healthy and unhealthy ingredients. Each person should carefully read the nutrition label of the various brands of protein bars in order to choose those that provide the highest levels of protein and the least amounts of processed sugars and fats.

What are the differences between protein bars and Whey protein supplements in powder form?

Both Whey protein powder and protein bars help ensure the availability of the essential amino acids needed to build new muscle fibres. Whey protein is obtained from whey, while bars combine multiple types of protein sources (milk, soy, collagen, peas).

Most bars contain Whey protein as their primary protein component. It is an ideal nutrient to consume after training, as it is digested and assimilated quickly. Amino acids from proteins reach the blood quickly to be used in the synthesis of new muscle proteins and tissue.

Protein bars also often contain casein (in the form of calcium caseinate), a slowly digested milk protein, which prevents muscle loss by providing amino acids in the medium and long term. So, if the bar combines Whey protein and caseinate, it ensures amino acid availability at all times.

Check out the table below for a visual representation of the main similarities and differences between these two protein products:

Whey protein powder Protein bar
Flavour May be neutral or strawberry, chocolate, vanilla, peanut butter, etc. Not available in neutral flavour. The most common flavours are: chocolate, caramel, vanilla and strawberry.
Form of consumption Must be mixed with water, milk or vegetable beverages before consumption. Ready to consume.
Minimum amount of protein per serving 21 grams 15 grams
Protein source Cow’s milk – whey. Cow’s milk (whey and casein), egg white, collagen, peas, seeds, soybeans.
Satiating capabilities Low, since although it contains proteins it does not provide fibre. High, provides protein and fibre, both of which are key nutrients that work to increase satiety.
Digestion and assimilation of protein (and its amino acids) Fast Slow

Do protein bars actually help increase muscle mass?

Protein bars guarantee that all the amino acids needed to synthesize new proteins are absorbed by the body and thus, the possibility of maintaining and increasing muscle mass is therefore guaranteed. However, without physical training it is impossible to continuously build muscle, even if protein bars are consumed daily.

It is important to consume protein bars at the right time to promote the development of muscle mass. The metabolic window, which corresponds to 30 to 45 minutes after the end of the training routine, is the best time to eat proteins because the body utilizes them more efficiently.

During this metabolic window of opportunity, proteins are broken down into amino acids, which reach the tissue to stop the muscle degradation that is initiated by physical exertion. They are also used to repair damaged muscle fibres and synthesize new muscle protein. As a result, muscle hypertrophy occurs.

Andrea MirandaNutritionist and director of the Argentinian Society of Aesthetics and Integral Nutrition (SAENI)

“A person who trains should incorporate between 1.8 and 2 grams of protein per kilo of their own weight daily in order to contribute to the regeneration of muscle cells.”

In what situations is it recommended to consume protein bars?

In the previous section, we explained that protein bars contribute to an increase in muscle mass if they are accompanied by a proper physical training program. Although it is not good to exceed the daily recommendation for protein intake, these dietary supplements are recommended for:

  • People who want to lose weight: protein bars have a high satiating capacity thanks to the proteins and dietary​ fibre they contain. In addition, thanks to its taste, reminiscent of sweets, they often help satisfy sweet cravings.
  • The elderly: The diet of older people is often insufficient in protein, either because of a decreased appetite or problems chewing meat, one of the main sources of protein in modern diets. Soft bars are a good food supplement for this demographic – this option also tends to be more appealing than milkshakes.
  • Individuals who want healthy and nutritious snacks on the go: Protein bars can be stored at room temperature and taken anywhere. That’s why they’re an excellent way to always have a healthy snack on hand.

Why are protein bars recommended for weight loss?

Protein bars are recommended as a compliment to any diet plan that is aimed at achieving weight loss. Its biggest role in losing weight lies in its satiating capacity which reduces appetite, decreasing the amount of food (calories) eaten throughout the day. In addition, its delicious flavour mitigates the desire for desserts, candy and other empty-calorie sweets.

Isabel HernandoResearcher at the Food Chemistry and Microstructure Group of the Universitat Politècnica de València

“Protein is the most effective macronutrient to provide a satiating effect.”

What is the recommended daily ration for protein bars?

Protein needs will vary from one individual to another according to their age, sex, physical activity (type, intensity, frequency, time of training), context, among other relevant characteristics. However, it is advisable to limit yourself to one protein bar a day, which can weigh between 30 and 60 grams.

Can a protein bar replace a main meal?

No, in no way can a food supplement replace a main meal for breakfast, lunch, or dinner. A balanced and varied diet, rich in fresh and natural foods, is essential for maintaining good health.

Protein bars can be eaten as a complementary healthy snack between main meals and after hard workouts.

Can people with diabetes consume protein bars?

This depends on the nutritional composition of the protein bar. Faced with the enormous variety of protein bar brands, the responsibility as a consumer is to read the nutrition label carefully. Diabetics should look for bars that are high in fibre, low in carbohydrates, and contain polyols as sweeteners.

Are there contraindications for the consumption of protein bars?

Protein bars do not usually have contraindications, although it is important not to exceed the recommended amount. Manufacturers of these products often state on the label that “excessive consumption of protein bars can have a laxative effect.” This is mainly due to the presence of alcoholic sugars (polyols).

Too much protein can lead to kidney or liver overload. Therefore, people with kidney or liver disease should consult their family doctor before consuming protein bars. Remember that those with lactose intolerance and those allergic to cow’s milk protein should also avoid most of these products.

What types of protein bars are there?

According to their ingredients, protein bars can be divided into two main groups: protein from animals and plant-based proteins. Animal protein bars use milk proteins (whey and casein), egg white, and collagen as sources of amino acids.

Bars suitable for vegans are made from protein derived from legumes, seeds or cereals. Both types of protein bars are capable of supplying all the necessary essential amino acids.

Purchase Criteria

As we’ve already mentioned, it’s not always easy to buy a healthy, nutritious protein bar. Most bars are made from Whey protein, but sometimes excess fat and sugars are added. Below you’ll find the basic purchasing criteria that you should take into account when choosing these types of products:

  • Flavour
  • Nutritional ​composition
  • Presence of allergens
  • Origin of ingredients

Flavour

Protein bars come in many different flavours: chocolate, raspberry, strawberry, cookies and cream, caramel, banana or vanilla, among many others. Some may have an artificial and not so pleasant taste , so you may have to try different brands until you find a protein bar that pleases you.

Nutritional composition

The protein bar you choose should provide a minimum of 12-15 grams of protein per serving and should be of high biological value. In addition, protein bars low in sugars, rich in fibre and with less than 8 grams of fat should be the preferred choice. Vegan bars may be slightly richer in fat, but they are usually unsaturated fats, which are a much more beneficial fat to the body than saturated fats.

Presence of allergens

Allergens are often present in protein bars, both of animal and plant origin. The most common allergens are: peanut, soybean, gluten, egg, sesame seed and nuts. People suffering from celiac disease, food allergies or lactose intolerance should read the nutritional label on their chosen products carefully to avoid negative reactions from consuming them.

Origin of ingredients

In the case of protein bars suitable for vegans, their ingredients are not only plant-based, but in most cases are also 100% organic. For people who want to eat a diet based on natural foods, even if they are not vegan, these bars are the best alternative.

Bars made from milk proteins generally cannot be consumed by lactose intolerant people, even if their label says otherwise.

foco

Many manufacturers claim that their bars are lactose-free, but after eating them consumers experienced flatulence, diarrhea and other digestive discomfort.

Summary

Protein bars promote an increase in muscle mass and promote physical recovery when consumed after training, as they guarantee a sufficient supply of essential amino acids. However, they can also be beneficial for losing weight and enriching the diet of older adults if consumed properly. The opposite to the desired effect can occur if these products are abused or used incorrectly.

Keep in mind that despite all their advantages, these food supplements are not always made with good quality ingredients. Sometimes it’s just a treat disguised and marketed as healthy food choice. That’s why it is your responsibility as the consumer to find out exactly what ingredients each bar has and their nutritional value.
