An Overview On Protein Bars

Sometimes you just need a little something to sustain you until the next meal. Few things can fill that need as well as a protein bar. Tucking discreetly into a laptop bag or purse, protein bars are not only filling, but they can also ensure you get the extra protein you need as you head to the gym to build muscle. Some prefer a protein boost after a workout to enhance muscle recovery.

Whatever your use, there are certain factors to look for in a protein bar. Perhaps the first of those features is taste. While this can be subjective, there are some bars that specialize in giving you plenty of dessert-like options. If your mouth waters at the thought of a cookies and cream protein bar, consider looking for an option that offers those rather than the standard flavors like peanut butter or dark chocolate.

There have been multiple studies showing the benefits of protein before hitting the gym. One study found that 20 grams of whey protein before a workout improved anabolic response. If you’re looking for that type of benefit, you’ll find few protein bars have quite that level of protein. If you just want to stay full between meals, though, a bar with a lesser amount could do it.

As you’re looking at ingredients, it can be tempting to go for a bar that has the most nutrients. Aside from needing protein for your workout, though, you may not need an excessive amount of fiber or vitamins. Keep in mind you’re probably getting plenty of these nutrients in the other food you’re eating throughout the day.

Natural ingredients are a top priority for many consumers. It’s hard to find a protein bar that is completely natural, but you’ll find many that prioritize organic ingredients. If you have food aversions or allergies, there are bars that leave out gluten and soy. You’ll also find some protein bar manufacturers steer clear of GMOs in their ingredients.

The Protein Bar Buying Guide

  • If you’re interested in protein bars, chances are health is a top priority. Look for a bar that is made from all-natural ingredients, like almonds, water, unsweetened chocolate and sea salt. However, you may find these bars have erythritol, a low-calorie sweetener that is a sugar alcohol, and sucralose, also known as Splenda, whose health effects have been questioned.
  • Consider a plant-based vegan bar that is both tasty and healthy. However, you’ll find some isolates, extracts and synthetic ingredients in these bars, so read the nutrition label carefully before buying.
  • If you’re concerned about genetically modified organisms, or GMOs, in your food, consider a protein bar made with no GMO ingredients. Some of these energy bars are made with rolled oats, chocolate and rich grains.
  • If you have food allergens or aversions, you’ll be glad to know that many of the bars are gluten-free. Some are also soy-free.
  • Of course, the top reason for choosing a protein bar is the protein itself. There are bars that have as much protein as 21 grams each. Others have just 8 or 9 grams of protein.
  • Fiber can also help with your overall health, especially when it comes to keeping you regular. If this is important to you, look for bars with as much as 14 grams of fiber.
  • Although taste can be subjective, some generally excel more than others. If you like dessert-like flavors, you may want to choose a brand that has plenty of decadent-sounding options like birthday cake, blueberry muffin and chocolate chip cookie dough.  Some energy bars can be on the dry side, so you’ll want to keep a bottle of water nearby while you’re downing it.
  • Hunger satisfaction is always an issue. Bars that are on the small side may not fill you up. However, these bars try to compensate for this by being low glycemic, which means the bars take longer to digest, keeping you full longer.
