Read the Label Right: How to Use Nutrition Facts to Make Healthier Choices

Standing in the grocery aisle, it’s easy to feel overwhelmed by all the claims on food packages—“high in protein,” “low fat,” “no added sugar.” But what do these phrases really mean? The real story is on the Nutrition Facts label. That small black-and-white box on the back or side of the package holds the key to understanding what’s in your food and how to make smarter choices for your health.
What Is the Nutrition Facts Label?
The Nutrition Facts label shows how much energy and nutrients a food contains. In the United States, it’s required on most packaged foods and beverages. Every label must list:
- Serving size and servings per container
- Calories per serving
- Total fat, saturated fat, and trans fat
- Cholesterol
- Sodium
- Total carbohydrates, dietary fiber, total sugars, and added sugars
- Protein
Many labels also include vitamins and minerals such as vitamin D, calcium, iron, and potassium. These numbers are based on one serving, so it’s important to check how many servings are in the package.
Start with Serving Size and Calories
The first thing to look at is the serving size. All the numbers on the label are based on this amount. If you eat double the serving size, you’re getting double the calories and nutrients listed.
Next, check the calories per serving. Calories measure how much energy you get from a food. If you’re trying to manage your weight, comparing calories between similar products can help you choose lower-calorie options without giving up flavor.
Fat – Focus on the Type, Not Just the Total
Fat is essential for your body, but not all fats are created equal. Look at both total fat and saturated fat. Too much saturated fat—found in butter, cheese, fatty meats, and many processed foods—can raise your cholesterol and increase the risk of heart disease.
Try to limit saturated fat and avoid trans fat whenever possible. Instead, choose foods with healthy unsaturated fats, such as those from nuts, seeds, avocados, and vegetable oils.
Watch Out for Added Sugars
Sugar can sneak into foods you wouldn’t expect—like salad dressings, sauces, and flavored yogurts. The label lists both total sugars and added sugars. Added sugars are those that don’t occur naturally in the food but are added during processing.
The Dietary Guidelines for Americans recommend keeping added sugars to less than 10% of your daily calories. Choosing foods with little or no added sugar can help you maintain steady energy levels and support long-term health.
Keep an Eye on Sodium
Most Americans consume far more sodium than they need, which can raise blood pressure and strain the heart. The Nutrition Facts label shows sodium in milligrams (mg) per serving.
A good rule of thumb: aim for less than 2,300 mg of sodium per day. When comparing products, choose the one with the lower sodium number—especially for items like soups, frozen meals, and snacks.
Fiber, Vitamins, and Minerals Matter Too
Dietary fiber helps keep your digestive system healthy and can lower cholesterol. Look for foods with at least 3 grams of fiber per serving. Whole grains, beans, fruits, and vegetables are great sources.
Also pay attention to vitamin D, calcium, iron, and potassium—nutrients many Americans don’t get enough of. Choosing foods rich in these can help support bone health, muscle function, and overall well-being.
Compare Products Using the % Daily Value
The % Daily Value (%DV) tells you how much a nutrient in one serving contributes to your daily diet, based on a 2,000-calorie day.
- 5% DV or less means the food is low in that nutrient.
- 20% DV or more means it’s high.
Use %DV to quickly compare products. For example, if you’re choosing between two cereals, pick the one lower in added sugars and sodium but higher in fiber and iron.
Be Mindful of Portions
Even if a product looks healthy, eating too much of it can add up. Many packages contain more than one serving, even if they appear to be single portions. Always check the serving size and adjust your expectations—or your portion—accordingly.
Use the Label as a Tool, Not a Rulebook
Reading the Nutrition Facts label isn’t about perfection or counting every calorie. It’s about awareness. When you understand what the numbers mean, you can make choices that fit your lifestyle and health goals.
As a general guide, aim for foods that are:
- Lower in saturated fat, added sugars, and sodium
- Higher in fiber, vitamins, and minerals
- Made with whole, minimally processed ingredients
A Healthier Life Starts in the Grocery Cart
Learning to read the label right is one of the simplest ways to take control of your diet. It might take a little practice at first, but soon it becomes second nature. Once you look beyond the marketing claims and focus on the facts, you’ll be better equipped to choose foods that nourish your body—and make every bite count.
