Nutritional labels are intended to inform consumers about the contents of their food, including calories, protein, fat, and sugar. However, many people may be surprised to learn that these labels are often designed with marketing strategies that can make the food seem healthier, less calorie-dense, or more nutritious than it truly is. A common tactic is the manipulation of serving sizes, which can make high-calorie, high-sugar foods appear less indulgent and encourage consumers to eat more without realizing it.

Here’s a look at how nutritional labels are used as a marketing tool and how they can lead consumers to unknowingly overconsume.

1. Manipulation of Serving Sizes

One of the most common ways nutritional labels can mislead consumers is through artificially small serving sizes. By setting a very small portion as the “serving size,” companies can create the illusion that the product is lower in calories, sugar, sodium, or fat than it actually is. For example, a bag of chips might list 150 calories per serving, but upon closer inspection, it turns out that a single serving is only a small handful of chips, rather than the full bag. This tactic allows companies to advertise the product as “low-calorie” or “low-fat,” even though most people will consume two or three servings in one sitting, unintentionally doubling or tripling their intake.

2. “Per Serving” vs. “Per Package”

Another misleading approach on nutritional labels is the breakdown of information “per serving” rather than for the entire package. This is particularly common with items that are often consumed in one sitting, such as single-serve bags of snacks, soft drinks, or candy bars. For instance, a 20-ounce bottle of soda might be labeled as two and a half servings, even though it’s frequently consumed as a single drink. This technique downplays the high calorie and sugar content, as many consumers may overlook or misinterpret the serving size details.

3. Calories and Sugars Labeled as “Free” or “Reduced”

Terms like “fat-free,” “sugar-free,” or “calorie-free” are often used on labels to attract health-conscious consumers. However, the definitions for these claims allow a degree of leeway that can be misleading. For example:

• “Calorie-Free” can still contain up to 5 calories per serving.
• “Sugar-Free” means it contains less than 0.5 grams of sugar per serving.
• “Fat-Free” can have up to 0.5 grams of fat per serving.

With these flexible definitions, companies can include small amounts of sugar, fat, or calories in each serving and still legally advertise their product as “free” of those ingredients. While 5 calories or 0.5 grams of sugar may seem insignificant, these numbers add up, especially if the serving size is small and people end up consuming multiple servings.

4. The Halo Effect of “Healthy” Ingredients

Some foods are marketed based on the presence of a single ingredient considered “healthy” or “natural,” even if the overall product isn’t particularly nutritious. For instance, products with added ingredients like chia seeds, quinoa, or “natural honey” might be marketed as healthy options, despite having high sugar or calorie content.

This tactic relies on what’s known as the halo effect—when a product is perceived as healthier overall due to the inclusion of a single health-focused ingredient. Consumers often ignore or downplay other nutritional information, like added sugars or fats, because the product’s label highlights a “healthy” ingredient.

5. Claims of “Natural” or “Organic” Ingredients

Labels that emphasize “natural,” “organic,” or “no artificial ingredients” create an impression that the product is inherently healthier. However, these terms don’t necessarily mean lower calorie, fat, or sugar content. For instance, organic cookies can contain just as many calories and as much sugar as their non-organic counterparts. While organic ingredients might be preferred for other reasons (like avoiding pesticides), they don’t guarantee a healthier product in terms of macronutrient balance or calorie count.

6. Hidden Sugars and Alternative Names

Manufacturers often use multiple types of sugar in a single product, listing them under various names like “cane syrup,” “maltose,” “fructose,” or “honey.” This practice allows companies to list sugar ingredients lower on the label and potentially avoid having “sugar” as the first ingredient. In reality, the combined sugars may still make up a significant portion of the product. This tactic downplays the high sugar content by scattering sugars across the ingredient list under less recognizable names.

7. Serving Size Inconsistency Across Similar Products

Different brands may use different serving sizes for nearly identical products, depending on how they want the nutritional profile to appear. For example, one brand of peanut butter may list a 1-tablespoon serving with 50 calories, while another brand lists a 2-tablespoon serving with 100 calories. Although the total calories per gram are the same, the smaller serving size may create the perception that the first brand’s product is “healthier” or “lower calorie,” influencing consumer decisions based on skewed comparisons.

8. “Light” and “Low” Labels That Aren’t Always Low-Calorie

Labels like “light” and “low-calorie” can be misleading, as they only have to be “lighter” or “lower” than the original version of that product—not necessarily low in absolute terms. For example, “light” mayonnaise may still contain a significant amount of fat and calories, just fewer than regular mayonnaise. The use of these labels can make products seem diet-friendly when, in reality, they may still be high in fats, sugars, or calories.

Why These Tactics Are Effective Marketing Tools

By controlling the narrative through serving sizes, language, and selective ingredient highlighting, companies influence consumer perceptions and choices. The misleading information often results in consumers underestimating the calorie, fat, or sugar content of the foods they consume, which can encourage overconsumption. In essence, when a product appears healthier on the label, people may feel comfortable consuming more of it, buying into the notion that they’re making a healthy choice—even when they’re not.

How to Read Labels More Critically

While nutritional labels can provide important information, it’s essential to read them critically:

• Check serving sizes carefully: Be aware of how many servings are in the package and adjust calculations if you plan to consume more than one serving.
• Look beyond health claims: Words like “light,” “natural,” or “organic” don’t necessarily mean low-calorie or low-sugar.
• Identify all sources of sugar: Scan for hidden sugars by learning their alternate names.
• Compare similar products: Check if serving sizes differ across brands to make fair comparisons.

Conclusion

Nutritional labels are tools intended to inform consumers, but they are also powerful marketing devices that can make products seem healthier or less calorie-dense than they are. By understanding how companies use serving sizes, alternative ingredient names, and selective language, consumers can make more informed choices about the foods they buy. Recognizing these marketing tactics allows for better awareness of true calorie, sugar, and fat content, supporting healthier decisions and helping consumers avoid unintended overconsumption.
