The 4 Most Important Things to Look for on a Nutrition Label

By Billy Tart, DNP, RN 

Standing in the grocery aisle, many people read the nutrition label, but few know which numbers are the most important. Nutrition labels can look complicated, but they are one of the most helpful tools we have for making healthier food choices. Instead of trying to analyze every number on the label, focus on four key things. 

1. Serving Size The serving size tells you how much of the food the nutrition information applies to. Many packages contain more than one serving. If a snack lists 200 calories per serving but the package contains two servings, eating the entire package means you consumed 400 calories. 

2. Calories Calories provide a quick snapshot of how much energy a food contains. Being mindful of calories can help support weight management, which plays an important role in preventing chronic diseases such as type 2 diabetes. 

3. Sugar and Sodium Many packaged foods contain more added sugar and salt than we realize. Diets high in added sugars can contribute to weight gain and increased diabetes risk. Too much sodium can raise blood pressure and increase the risk of heart disease. 

4. Fiber Fiber is found in foods like whole grains, beans, fruits, and vegetables. Foods higher in fiber help you feel full longer, support digestion, and can help maintain healthy blood sugar levels. 

For general guidance, most adults should aim for less than 2,300 mg of sodium per day, limit added sugars, and try to get about 25–38 grams of fiber daily. Learning to read a nutrition label is a simple skill that can help you make healthier choices.
