Are protein bars good for you?
Are protein bars good for you? They’ve certainly become popular as an easy, go-to snack on the way to or from the gym, and for those days when you don’t have time for a meal. They can even be used as an aid to help weight loss. But are protein bars a healthy snack? Does it depend on the brand or flavor you buy? And, are some protein bars an unhealthier choice than a bag of chips or a chocolate bar?
Sometimes called energy bars, protein bars can contain a range of ingredients, from the healthy to the surprisingly unhealthy. While many of the best protein bars are packed with seeds, nuts and whole grains, some can also come loaded with added sugar and sweeteners – often to mask the bitter taste of some of their more healthy ingredients.
When it comes to choosing a healthy protein bar, knowing what ingredients to look for on the packaging, and understanding basic nutritional information, can help you make an informed choice.
This article takes a closer look at protein bars, their nutritional makeup, and what health benefits they provide. It also considers whether protein bars are the healthiest way to get the protein you need.
Are protein bars good for you: Nutrition
When it comes to how ‘good’ protein bars are for you, it depends on the brand of protein bar and what ingredients go into the bar. Most protein bars contain a good mix of ingredients that provide flavor and texture, such as nuts, seeds and dried fruit. They may also contain whole grains, such as oats. To bind these ingredients together, and improve the overall flavor, they may also contain sugar syrups, artificial sweeteners, chocolate, milk, eggs, or yogurt powder. Vegan brands may choose to use plant-based agents, such as soy or rice.
Given the variety of ingredients, it’s impossible to say whether every protein bar is good for you. But knowing standard nutritional information can help. According to the US Department of Agriculture, an average 63g protein bar will contain the following nutrition:
| Amount | % Daily value | |
| Energy | 250 kcal | |
| Protein | 20 g | 40% |
| Total lipid (fat) | 9 g | 14% |
| Carbohydrate | 26 g | 9% |
| Fiber | 10 g | 40% |
| Sugars | 8 g | |
| Calcium | 150 mg | 15% |
| Iron | 1.08 mg | 6% |
| Potassium | 120 mg | 3% |
| Sodium | 170 mg | 7% |
| Fatty acids | 3.5 g | 18% |
| Cholesterol | 5.04 mg | 1% |
Using this as a guide, we can see that our average protein bar is a great source of protein, fiber, and calcium. It’s also a good source of carbohydrate and iron.
It’s important to note that not all protein bar manufacturers show their ingredients on the packaging. Some use a blend of ingredients that are kept secret from their competitors, so it can be difficult to know exactly what you’re taking into your body. Opting for protein bars that have a full list of ingredients will help you make a more informed choice.
Many protein bars use highly processed forms of protein to load their bars, instead of using less-processed foods. So you may notice ingredients such as whey protein isolates or soy protein isolates. If you want to avoid more refined and processed foods in your diet, you may want to give these a swerve and opt for bars that pack more protein from less-processed sources, such as nuts, grains, and seeds.
What are the potential benefits of protein bars?
You may be wondering if there are any potential benefits to eating a protein bar, and the good news is, there definitely can be. Let’s take a closer look at some of the most common.
Weight loss
Many people use protein bars as an aid to achieving weight loss. Protein can help to have a “filling effect” on the body, curbing the urge to snack between meals or eat more than you need to at mealtimes.
A 2019 study into 62 overweight women in Korea looked at how having a daily protein bar reduced calorie consumption. Researchers found that, on average, the women reduced their daily calorie intake by up to 39%. They also achieved weight loss and improved their blood cholesterol level.
Weight gain
Protein bars can also be helpful if you need to pack on weight, for example, if you have a thyroid imbalance or find it difficult to make time to have regular meals.
If you need to increase your daily calorie count, a protein bar can give you around 250kcal extra a day – with some providing more. Although eating a protein bar is better than relying on fatty foods and sweet snacks, you should try to aim for regular meals and healthy snacks to pack on the pounds instead. But having a protein bar in your pocket can help it along. Just look for bars that have fewer refined and processed ingredients, artificial sweeteners and additives.
Muscle gain
Adding protein to your diet can help you to gain muscle. This is because healthy, high-protein foods can aid muscles in repairing themselves after exercise, stimulating more muscle growth.
The International Society of Sports Nutrition advises eating up to 3g of protein per kilogram of body weight every day, to optimize muscle growth during high-intensity resistance training. Although it recommends…
