Decoding the Food We Eat: A Guide to What is Nutrition Labelling?

4 min read

According to the World Health Organization, effective nutrition labelling is a key strategy to address the global concern of unhealthy diets by helping consumers make healthier food choices. So, what is nutrition labelling? It is the descriptive statement on food packaging intended to inform consumers about the nutritional properties of the food.

Quick Summary

Nutrition labelling is the standardized information panel on packaged foods detailing calories, serving sizes, and nutrient content to help consumers understand a product's nutritional value and make healthier decisions.

Key Points

  • Serving Size is Key: The entire nutrition label is based on the single serving size listed, not the entire package.

  • Decode Daily Value (%DV): The %DV indicates how much a nutrient in one serving contributes to your daily diet; 5% or less is low, and 20% or more is high.

  • Limit Certain Nutrients: Pay attention to and limit your intake of saturated fat, sodium, and added sugars, which can have adverse health effects.

  • Boost Beneficial Nutrients: Actively seek out foods with higher percentages of dietary fiber, Vitamin D, calcium, iron, and potassium.

  • Read the Ingredient List: Always check the ingredient list, which orders components by weight, to find hidden sugars and confirm allergens.

  • Verify Claims: Don't rely solely on marketing slogans; use the facts panel to verify nutritional claims like 'low-fat' or 'high-fiber'.

The modern grocery store is a bustling hub of choices, and standing out among the colorful and eye-catching packaging is a small, but vital, box of text: the nutrition label. This standardized information panel, required by regulatory bodies like the FDA in the United States, is an essential tool for anyone looking to understand their diet better. It provides crucial, at-a-glance information that empowers you to compare products and manage your intake of specific nutrients. Mastering how to read this label can transform your grocery shopping experience and put you in control of your nutritional goals.

The Core Components of a Nutrition Facts Label

To effectively use a nutrition label, you must understand its main components. Each section provides a different piece of the puzzle that, when put together, gives you a full picture of what you're consuming.

Serving Information: Size and Servings Per Container

Located at the very top of the panel, the serving information is the foundation for all other details on the label. It states the serving size—the amount people typically consume—and the number of servings in the package. It is critical to remember that all calorie and nutrient values listed below this section are based on this single serving size. If you eat two servings, you must double all the values listed.

Calories

Calories indicate the amount of energy provided by one serving of the food. This number helps you balance the energy you take in from food with the energy your body expends through daily activities. A product may have different calorie counts displayed for the standard serving or for the entire package, especially if it's a single-serving container.

Key Nutrients to Limit and Increase

The label identifies several key nutrients, categorizing them into those you should limit and those you should aim to get more of. Public health experts have identified that many people in the US consume too much saturated fat, sodium, and added sugars, while often not getting enough dietary fiber, Vitamin D, calcium, iron, and potassium.

  • Nutrients to Limit: Saturated Fat, Sodium, and Added Sugars. Diets high in these have been associated with an increased risk of certain health conditions.
  • Nutrients to Increase: Dietary Fiber, Vitamin D, Calcium, Iron, and Potassium. A diet rich in these nutrients supports overall health and can help reduce the risk of certain diseases.

The Percent Daily Value (%DV)

The %DV shows how much a single serving of a food contributes to your total daily diet, based on a standard 2,000-calorie diet. The %DV provides a quick, standardized way to assess a product's nutritional contribution, rather than requiring complex calculations. As a general guide, 5% DV or less is considered low for a nutrient, while 20% DV or more is considered high. This makes comparing similar products straightforward—just ensure the serving sizes are the same.

Beyond the Facts Panel: The Ingredient List

Separate from the Nutrition Facts panel is the ingredient list, which is just as important for making informed decisions. Ingredients are listed in descending order by weight, meaning the first ingredient makes up the largest proportion of the product. This is especially useful for identifying added sugars, which can be disguised under multiple names, and for pinpointing potential allergens. Most major food allergens are also clearly emphasized on the label, often in bold text, to help those with allergies or sensitivities.

How to Use Nutrition Labels for a Healthier Diet

  • Compare Products: Use the %DV to compare different brands of a similar product, such as cereal. A higher %DV for fiber and lower %DV for added sugars and sodium indicates a healthier choice.
  • Balance Your Intake: The %DV helps you make dietary trade-offs throughout the day. If a meal is high in sodium, you can balance it by choosing low-sodium options for your other meals.
  • Check Serving Size: Always look at the serving size first. If you eat the entire bag of chips, you need to calculate the nutrient intake for the number of servings in the bag, not just one.
  • Scan the Ingredient List: Use the ingredient list to look for hidden sugars or to avoid allergens. Remember, the ingredients at the top are the most abundant.
  • Be Aware of Claims: Use the facts panel and ingredient list to verify marketing claims on the front of the packaging. A "low-fat" product might be high in added sugars, for example.

Comparing Nutrition Labels: US vs. EU

While the goal of providing nutritional information is universal, different regions have distinct labeling requirements. Below is a comparison of some key differences between labels in the United States and the European Union.

Feature United States (FDA) European Union (EU)
Energy Expressed in Calories (Cal) Expressed in both kilojoules (kJ) and kilocalories (kcal) per 100g/ml
Serving Size Required, based on amounts people typically eat Not required; nutrients are expressed per 100g/ml
Sodium/Salt Lists sodium content in milligrams (mg) Lists salt content in grams (g)
Additives Listed by their full name (e.g., Sodium caseinate) Often assigned a code number, known as an "E number"
Allergens Eight major allergens must be declared The 14 main allergens must be emphasized every time they appear in the ingredients list

Conclusion

Nutrition labelling is a powerful tool for navigating the food landscape. By learning to read and interpret these labels, consumers can make more conscious and informed decisions about their health. The combination of the Nutrition Facts panel, the ingredients list, and understanding local regulations provides a comprehensive roadmap for achieving your nutritional goals. While labels can seem complex, taking the time to understand them offers a significant return on investment for your overall well-being. By focusing on serving sizes, balancing your intake of certain nutrients, and checking the ingredient list, you can successfully decode the food you eat and choose a diet that works for you.

Frequently Asked Questions

The % Daily Value (%DV) shows how much one serving of a food contributes to your total daily diet, based on a 2,000-calorie diet. It helps you assess if a food is high or low in a particular nutrient at a glance; 5% DV or less is low, while 20% DV or more is high.

The serving size is the amount people typically eat or drink, and all nutrient information on the label is for that single serving. If you consume more than one serving, you must multiply all the listed nutrient and calorie amounts by the number of servings you've had.

Total Sugars includes all sugars in the product, both those naturally found in ingredients like fruit and milk, and any added sugars. Added Sugars are sweeteners, syrups, and honey added during processing. It is recommended to limit your intake of added sugars.

The ingredient list is crucial for identifying hidden components and allergens. Ingredients are listed in descending order by weight, so the first ingredient listed is the most prevalent in the product.

By reading nutrition labels, you can compare products, manage your intake of specific nutrients like saturated fat and sodium, and make dietary trade-offs to meet your health goals. For example, if one food is high in sodium, you can choose low-sodium options for your other meals.

No, nutrition labelling standards vary by country. For example, the US lists sodium in milligrams, while the EU lists salt in grams. Serving size conventions and allergen declarations also differ.

A 'Contains' statement is often used to clearly declare the presence of major food allergens, such as milk, eggs, peanuts, or wheat, immediately after or next to the list of ingredients. This makes it easier for people with allergies to identify potentially harmful ingredients.
