Shopping Guide: Everything You Should Know About Protein Bars
Knowing all the relevant information regarding these products will help you achieve your desired results. Keep in mind that even if you buy the best protein bar on the market, if you don’t consume it properly or in the right amounts, you’ll be sabotaging your results, and may actually even damage your health. To make sure you can make an informed decision, this next section includes all the relevant information one should know before buying a protein bar.
What are protein bars exactly?
A protein is considered to be of high biological value when it made up of all (or almost all) of the essential amino acids. If any of these amino acids are missing, those proteins cannot be synthesised to repair or build new tissue, this includes muscles.
In short, a good protein bar often combines high-value proteins mixed with other important macronutrients, like good fats, good carbs, and other dietary fibres. These ingredients are combined with other flavourful ingredients to create a tasty and nutritious food supplement.
Keep in mind that the quality and proportion of the sugars and fats, along with the amount of high-value protein in the recipe, will determine the nutritional value of the bar.
What are the typical ingredients in a protein bars?
Generally speaking, protein bars are often made with the following compounds:
- Proteins: A good protein bar will offer a high amount of quality protein. Either vegetable or animal. This ensures an adequate amount of all the amino acids which are essential to the proper functioning of the human body. These include: tryptophan, threonine, phenylalanine, methionine, leucine, isoleucine, valine and lysine.
- Protein sources: Most of the protein in these bars are: Whey protein, milk protein, calcium caseinate, hydrolyzed collagen, soy protein, pea protein, hemp seed protein, among many others.
- Carbohydrates: In some cases, simple carbs are used to sweeten protein bars. However, in high-quality bars, polyols (sugar alcohols) are utilised. Polyols don’t damage teeth or raise blood glucose (blood sugar) levels.
- Fats: Most of the fat content in protein bars comes from the coating. These are usually made of a combination of oils and white or dark chocolate. Unfortunately, the oils used are generally saturated and hydrogenated fats (trans fats). This is to make them tastier, however, this does huge damage to the nutritional impact of the bar you choose.
- Food fiber: This element is super important to the overall outcome of eating a protein bar. Food fibre is responsible for the satiating qualities of the bar, which means the more fibre, the longer you’ll feel full. Another important function of fibre is that it slows down our bodies ability to absorb sugar, preventing spikes in blood glucose — specifically beneficial to people with diabetes or insulin resistance.
- Flavours and colourings: When speaking of organic or natural protein bars, foods with intense aromas and flavours are used to give taste and improve the smell of the product. Keep an eye out for processed bars, since these often contain an excessive amount of artificial and synthetic additives meant to improve their flavour.
Next, we’ll present you with a visual representation of the ingredients you may find in a protein bar, along with the nutritional value and health benefits:
|Protein||Whey protein, milk protein concentrate (whey + casein), milk protein isolate, calcium caseinate, egg white protein, hydrolysed 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 fertilisers are used during 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?
What are the differences between protein bars and whey protein supplements in powder form?
Because whey protein is digested and assimilated by the body pretty quickly, it is an ideal nutrient to ingest after training. Its fast absorption allows the amino acids in the protein to reach the blood very fast, allowing them to be used right away in the synthesis of new proteins and muscle tissue. This quality has made whey one of the most popular ingredients in protein bars.
Another popular ingredient in protein bars is casein (in the form of calcium caseinate), a slowly digested milk protein. The fact that it’s slowly digested means that it can prevent muscle loss by providing essential amino acids in the medium and long term. Ideally, find a product that includes both whey and casein, this way, you’re sure to have the necessary amino acids at all times.
If you want to understand the difference between protein powder and protein bars, check out the table below:
|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||0.74 oz.||0.52 oz.|
|Protein source||Cow’s milk – whey.||Cow’s milk (whey and casein), egg white, collagen, peas, seeds, soybeans.|
|Satiating capabilities||Low, it does not provide high amounts of 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?
Moreover, you should know that consuming the protein bar at the right time is an important factor that will affect your results. The best time to ingest a protein bar to support building new muscle is roughly 30 to 45 minutes after the end of your training session. It is during this time that the body will utilise the nutrients most efficiently.
During this metabolic window, the proteins in the bars are broken down into amino acids, which go to the muscle tissue to halt the muscle degradation started by physical exertion. During this time, these amino acids are also used to heal and regenerate damaged muscle fibers by synthesising new muscle proteins. This is when muscle growth happens.
Who would benefit from the use of protein bars?
- People who want to lose weight: Protein bars have a high satiating capacity, this is thanks to the high amount of protein and food fibres included in them. Moreover, protein bars are often sweet, and a healthier alternative to candy bars, helping you curb cravings.
- The elderly: Oftentimes, seniors may not get all the protein they need from their diet. This may be due to decreased appetite or difficulty chewing meat (one of the main sources of protein in Great Britain). Soft bars are a good alternative for this demographic.
- Individuals who want healthy and nutritious snacks on the go: Protein bars can be stored at room temperature and taken anywhere. For this reason, they have become popular healthy snacks that can be kept on hand.
Why are protein bars recommended for weight loss?
What is the recommended daily intake for protein bars?
Can a protein bar replace a main meal?
Protein bars are meant to compliment your diet, not to substitute entire meals.
Can people with diabetes have protein bars?
Who should stay away from consuming protein bars?
Moreover, it’s good to keep in mind that too much protein can overload the kidneys and liver. This means that anyone with kidney or liver issues should consult a doctor before taking up protein bars. Last but not least, anyone who suffers from lactose intolerances should opt for vegan products to avoid any negative interaction with proteins derived from milk.
What types of protein bars are there?
In contrast, there are also many bars which are suitable for vegans, these have proteins derived mainly from legumes, seeds or cereals. Both types of protein bars (as long as they are made with quality ingredients) have the capability of supplying us with all the essential amino acids.
By now you know that it’s not always going to be easy to find a healthy and nutritious protein bar. Despite the fact that they will include protein, often times they also have excess fat and lots of sugar added to boost flavour. To help you find high quality products, we would like to give you one last set of criteria to consider before purchasing one of these food supplements.
In the UK, we can find protein bars in all sorts of flavours, the most common ones, however, are chocolate, strawberry, cookies and cream, caramel or vanilla. Because some bars out there may have artificial and not so yummy flavours, you may have to trie different brands and varieties to find the best protein bar for your taste.
At the end of the day, the nutritional load of the protein bar you choose should be the most important deciding factor. Make sure that the bar you choose has 20-30g. of high biological value protein per serving. Furthermore, look for protein bars that are low in sugar, rich in fibre and that have less than 8g. of fat per serving. Keep in mind that vegan bars may have a slightly higher fat content. However, this is usually not a big deal since these fats are usually unsaturated, which are much more beneficial to our organisms than saturated fats.
Unfortunately, protein bars often have the presence of allergens, regardless of whether they are animal and plant-based protein bars. The most common allergens found in these food supplements are peanut, soybean, gluten, egg, sesame seeds, and nuts. People suffering from food allergies or intolerances should always read the ingredients label carefully before eating any new products in order to avoid any possible complications.
People who want to eat a diet mostly based on natural and whole foods should opt for vegan bars since these are usually made with 100% organic ingredients — you don’t have to be vegan to benefit from these quality products! Moreover, these will be great alternatives for people who are lactose intolerant.
When consumed post-training, protein bars can encourage new muscle growth and faster muscle recovery. Ingesting these bars will guarantee you have an ample supply of essential amino acids. Furthermore, these food supplements can also be great tools for people wanting to lose weight, since they will help you curb cravings and stay full for longer. However, the opposite can happen if these products are abused or used incorrectly.
When looking for the perfect protein bar for you, be diligent and make sure the product you choose is made with good quality ingredients. A lot of the times you can find products that have more in common with a chocolate bar than a nutritious piece of food. Remember that at the end of the day, it is your responsibility as the consumer to ensure the products you buy offer you a good nutritional value.
