How to Read Nutrition Labels Like a Pro

January 13, 2026

A person closely examining the nutrition label on a food product.

The nutrition facts label is your roadmap to making informed food choices, but it can often feel like reading a foreign language. Understanding just a few key sections can transform your grocery shopping and empower you to choose foods that truly align with your health goals. Let's break down how to read it like a pro.

Start with the Serving Size. This is the most crucial, and often most misleading, part of the label. All the numbers that follow, from calories to sodium, are based on this single serving. A small bag of chips might contain three servings, meaning you need to multiply all the values by three to understand what you're actually consuming. Always check the 'Servings Per Container' to get the full picture.

Next, look at the Calories. This number tells you how much energy you get from a serving. While calorie counting is a useful tool, the source of those calories matters just as much. 200 calories from an avocado provide healthy fats and fiber, while 200 calories from a soda are just sugar. Use the calorie count as a guide, but don't stop there.

The core of the label is the Macronutrients: Fat, Carbohydrates, and Protein. Pay attention to the types of fat; aim for lower Saturated and zero Trans Fats. For carbohydrates, look at the Dietary Fiber (more is better!) and a lower number for Added Sugars. The daily value percentage (%DV) is a helpful shortcut. It shows how much a nutrient in a serving contributes to a total daily diet. A DV of 5% or less is low, while 20% or more is high.

Finally, scan the Ingredient List. Ingredients are listed by weight, from most to least. If sugar, high-fructose corn syrup, or other sweeteners are among the first few ingredients, it's a red flag. A shorter ingredient list with recognizable, whole-food names is generally a sign of a less processed, healthier product. By mastering these simple checks, you can take control of your nutrition one label at a time.
