Considerations when choosing nutrition bars
Types of nutrition bars
Energy bars: These bars have higher carbohydrates at around 20 to 40 grams. They also contain up to 20 grams of sugar. They're a good temporary boost to tide you over until your next meal.
Meal replacement bars: These bars have higher calorie contents -- usually over 300 -- to be more filling. They also tend to have more protein and fiber. They're a fine substitute for a meal but shouldn't regularly replace them.
Snack bars: These bars are essentially healthier alternatives to other snack foods. They usually have a higher sugar content than protein. While they have some nutritional strengths, more than anything, they're a treat with some positive macros.
Macros to compare
Protein: Protein aids in building muscle and helps you feel full longer. Nutrition bars can have between four and 20 grams of protein per bar, though most of them hover around eight to 12 grams. If you're weight training, high-protein bars are perfect as post-workout snacks.
Carbohydrates: Carbohydrates provide a burst of energy, though they won't make you feel satisfied as long as protein. Expect to find between four and 25 grams of carbohydrates in most nutrition bars. If you need a burst of energy and it's not too long until your next meal, high-carb nutrition bars are a good option.
Fiber: Fiber aids in regular bowel movements and, like protein, contributes to a satisfied feeling. On average, nutrition bars offer between three and eight grams of fiber. Opt for a high-fiber bar if you need a substantial snack, or if you need help reaching your daily fiber goal -- for men this is around 30 grams, and for women it's 25 grams.
Fat: Monounsaturated and polyunsaturated fats are considered healthy fats. Common healthy fats in nutrition bars include nut butters, chia seeds, and coconut. Trans fats, on the other hand, are considered unhealthy fats as they contribute to heart disease. As a rule of thumb, sticking to nutrition bars lower in all fats is best for staying heart-healthy.
Sugar: Nutrition bars contain natural sugars, artificial sweeteners, and sugar alcohols. It's a good idea to choose a lower-sugar bar, preferably natural sugar, especially if your goal is weight loss. While artificial sweeteners and sugar alcohols won't spike your insulin, there are some studies that suggest they may have negative impacts on your long-term health.
If you have health issues, such as food intolerances or allergies, it's important to read ingredient lists carefully. Many brands take these concerns to heart and list if their bars are vegan, gluten-friendly, or sugar-free.
Some bars advertise if they're diet-friendly, which is helpful if you follow a specific diet, like paleo or keto. Some consumers say there are mild discrepancies, but if you only model your intake after a diet, you'll be fine in the gray area.
Single nutrition bars cost between $1 and $4 per bar, so if you consume them often, you're better off investing in a value pack of five to 24 bars at a time. Generally speaking, the better the ingredient quality, the more the bar costs.
Q. My nutrition bar contains carrageenan. What's that?
A. Derived from seaweed, carrageenan is an inexpensive thickening agent. It gives the nutrition bar a creamier, denser consistency. Some people who have certain health conditions and food sensitivities may experience gastrointestinal issues from it.
Q. Should I refrigerate my nutrition bar?
A. No, because it can harden the bar and make it difficult to break apart and chew. There are certain nutrition bars that are supposed to be refrigerated and have much softer, chewier consistencies.
