Lower-calorie foods and breads are popping up on supermarket shelves. However, not all lower-calorie breads are good for you. Find out what low-calorie bread really means, how to select lower-calorie breads and some of our favorite loaves to buy now.

What Is Low-Calorie Bread?

The term "low calorie" is defined by the Food and Drug Administration (FDA) as 40 calories or less per reference amount customarily consumed. In layman's terms, low calorie means 40 calories or less per serving. For most brands on the market, packaging indicates that one slice is a serving.

Keep in mind, low-calorie bread does not automatically mean the bread is low-carb. When the nutrition facts panel on bread indicates that it's low in calories, that doesn't mean it's necessarily low in carbs. The same is true if the bread is low in carbs; that doesn't mean that the bread is low in calories, as it can be made with ingredients other than carbs. When looking for low-calorie bread, always read the label to make sure you're getting what you're looking for.

How to Choose Healthy Lower-Calorie Bread

A typical slice of store-bought bread has about 100 to 110 calories. It's tough to find low-calorie bread that’s 40 calories or less per slice, so it's reasonable to opt for a lower-calorie bread with around 60 calories per slice.

Fiber is an under-consumed nutrient by all Americans in every life stage. It's recommended to look for 100-percent whole-grain bread in order to meet fiber needs. According to The Nutrition Source at the Harvard T.H. Chan School of Public Health, dietary fiber intake among US adults is, on average, 15 grams per day. This is about half the amount of the recommended 25 to 30 grams per day from food, not supplements.

You can also find lower-calorie refined bread that is enriched and fortified with B vitamins, iron and folate. This is also important to add to your diet, as these nutrients have been added to refined breads in order to prevent deficiencies. As such, we haven't seen B-vitamin deficiencies in the US since they were added to flour and breads in the 1940s. In addition, in 1998, the FDA implemented mandatory folic acid fortification of enriched cereal grain products, including refined bread. Post-fortification analysis found a 28 percent reduction in neural tube disorder birth prevalence, which is caused by a lack of folate in the diet.

Taste is certainly something you should consider when purchasing lower-calorie breads. Your best bet is to give several brands a try to see which you like best. You can even rotate between several favorites.
