What is the 5/20 rule on food labels and how to use it?

6 min read

According to the FDA, the % Daily Value (%DV) is a crucial part of the nutrition label, showing how much a nutrient in a serving of food contributes to your daily diet. This information forms the basis of the 5/20 rule on food labels, a simple and effective guideline to help you quickly assess a food's nutritional profile.

Quick Summary

The 5/20 rule is a simple guide for interpreting food labels. If a nutrient has a %DV of 5% or less, it's considered low; if it has a %DV of 20% or more, it's high. This quick reference helps you make informed choices, aiming for low percentages in nutrients like saturated fat and sodium and high percentages in beneficial ones like fiber and vitamins.

Key Points

  • Low Nutrient Intake: 5% DV or less indicates a low amount of a nutrient per serving.

  • High Nutrient Intake: 20% DV or more signifies a high amount of a nutrient per serving.

  • Nutrient Balancing: Apply the rule to limit saturated fat, sodium, and added sugars (low %DV) and boost fiber, vitamins, and minerals (high %DV).

  • Serving Size Consideration: Remember that the %DV is based on a single serving, so check how many servings are in the package.

  • Context is Crucial: The 5/20 rule is a tool for comparison and quick assessment, not a substitute for understanding the full nutrition label and your overall diet.

Demystifying the Nutrition Label: What is the 5/20 Rule on Food Labels?

Navigating the sea of information on a food nutrition label can be confusing for many. Calories, grams, and percentages can easily overwhelm even the most health-conscious consumer. Fortunately, the Food and Drug Administration (FDA) provides a straightforward tool to help: the 5/20 rule. This simple principle allows you to quickly determine if a food is a good source of a nutrient you want more of, or if it's high in something you'd prefer to limit. By understanding and applying this rule, you can make smarter, faster decisions in the grocery store and build a healthier eating pattern.

How the 5/20 Rule Works

The 5/20 rule is a guideline that relies on the Percent Daily Value (%DV) column found on every standard Nutrition Facts label. The %DV represents how much a nutrient in a single serving of the food contributes to a total daily diet, which is typically based on a 2,000-calorie diet for general advice. The rule is split into two parts:

  • 5% DV or less is considered LOW: This indicates that a food is not a significant source of that nutrient. When shopping, you should look for a low %DV in nutrients that you want to limit, such as saturated fat, sodium, and added sugars. For example, if a can of soup has a 4% DV for sodium, it is considered low in sodium per serving.
  • 20% DV or more is considered HIGH: This signifies that a food provides a substantial amount of a nutrient. You should aim for a high %DV for beneficial nutrients like dietary fiber, vitamin D, calcium, and iron. A product with a 25% DV for dietary fiber is an excellent source of fiber, and a wise choice if you are trying to increase your intake.

Applying the Rule to Nutrients

To put the 5/20 rule into practice, you need to understand which nutrients you should be seeking in higher amounts and which you should be limiting. Think of the nutrition label as a balancing act, where the rule provides the framework for your decisions.

Nutrients to Keep LOW (Aim for 5% DV or Less):

  • Saturated Fat: High intake can raise cholesterol levels and increase the risk of heart disease.
  • Sodium: Excessive sodium contributes to high blood pressure.
  • Added Sugars: These contribute calories without significant nutritional benefit and can lead to weight gain and other health issues.

Nutrients to Keep HIGH (Aim for 20% DV or More):

  • Dietary Fiber: Promotes digestive health, helps manage weight, and may reduce blood cholesterol.
  • Vitamin D: Essential for bone health and overall immunity.
  • Calcium: Crucial for strong bones and teeth.
  • Iron: Important for red blood cell function and preventing anemia.
  • Potassium: Helps maintain healthy blood pressure.

A Simple Shopping Comparison with the 5/20 Rule

Here is a quick example of how you can use the 5/20 rule to compare two different products in the grocery store. Imagine you are choosing between two brands of yogurt and are concerned about sodium and calcium intake.

Feature Brand A Yogurt (%DV) Brand B Yogurt (%DV)
Sodium 4% 15%
Dietary Fiber 1% 2%
Calcium 25% 10%

Using the 5/20 rule, Brand A is the healthier choice. It is low in sodium (4%, which is under 5%), while Brand B is getting closer to the higher end of the spectrum (15%). Furthermore, Brand A is high in calcium (25%, which is over 20%), making it an excellent source, whereas Brand B is only a moderate source. This quick comparison allows you to make an informed decision without needing to calculate grams or fully analyze each nutrient.

Limitations and Best Practices

While the 5/20 rule is an incredibly useful shortcut, it's not a substitute for reading the entire label. Here are some additional tips for using it effectively:

  • Serving Size is Key: The %DV is based on a single serving. Always check the serving size and the number of servings per container. If you eat the entire package, you must multiply the %DV by the number of servings to get the true nutritional impact.
  • Overall Diet Matters Most: The rule is a tool for comparing single products, but your overall diet is what truly impacts your health. A single treat that's high in sugar isn't a disaster if your overall eating pattern is balanced.
  • Read the Ingredients List: The 5/20 rule won't tell you everything about a food. Check the ingredients list to spot highly processed or artificial ingredients. Ingredients are listed in descending order by weight, so those at the top are most abundant.
  • Check for Missing Information: Note that some nutrients, like trans fat, don't have a %DV on the label, so you must use the grams to compare.

Conclusion

In a world where consumers are increasingly health-conscious but time-poor, the what is the 5/20 rule on food labels question is an essential one. This simple, reliable method provides an instant way to decipher complex nutritional information. By aiming for a %DV of 5% or less for nutrients to limit and 20% or more for those to seek out, you empower yourself to make healthier decisions at a glance. While it should be used in conjunction with a deeper understanding of food, the 5/20 rule is a powerful first step toward informed and healthy eating habits.
