You’re in the snack aisle and a bag of chips catches your eye. The package—which is covered in leafy green graphics—promises that it’s gluten-free and made with “natural” ingredients. You toss it in your cart feeling pretty good about it.

Then you get home, flip it over, and find sodium and fat counts pretty darn close to those of the regular chips you were trying to avoid.

If that’s happened to you, you’re in good company. As a registered dietitian, I hear some version of this story from clients all the time. Smart, health-conscious people get caught by what researchers call the “health halo,” a label or claim that makes a food seem healthier than it really is.

The good news is that once you know how health halos work, they get much easier to spot. Here’s what the research says, and how you can shop with more confidence.

What is a health halo?

A health halo forms when one appealing feature of a food shapes how you judge the whole thing. One word on the front of a package, like “organic,” “low-fat,” or “plant-based,” can make you assume the food is more nutritious, lower in calories, or better for you overall.

The problem is that most of these terms describe only one thing. For instance, “gluten-free” simply tells you that it doesn’t contain a certain protein. “Organic” tells you how something was grown or produced. Neither tells you how much sugar, sodium, or saturated fat is inside.

In other words, these claims can create a shortcut in your brain, making a food seem healthier overall than it really is. That’s why it’s worth looking beyond the buzzwords before tossing something into your cart.

Common labels that create a halo

Now, these claims aren’t false. In fact, many are regulated. The problem is just that folks tend to ascribe more benefits to them than they deliver.

“Gluten-free”

The FDA allows this label on foods with less than 20 parts per million of gluten. That matters a lot for people with celiac disease. For everyone else, though, a gluten-free cookie is still a cookie. And some gluten-free products are made with refined starches and can have less fiber than their regular versions.

“Natural”

This is one that surprises people. The FDAhas not formally defined “natural” on food labels. It does have a longstanding policy, though—so informal guidance, not a formal legal definition—that the term means nothing artificial or synthetic was added that you wouldn’t normally expect in the food. That says nothing about nutrition, and a “natural” product can still be high in added sugar.

“Organic”

The USDA’sorganic standards cover how foods are grown, raised, and processed. That includes limits on synthetic pesticides and certain additives. These are meaningful standards, but they’re about production, not nutrition. Organic candy is still candy.

“Low-fat” or “reduced-fat”

These terms have specific FDA definitions: “low-fat” means a food contains 3 grams of fat or less per serving, while “reduced-fat” means it has at least 25% less fat per serving than the standard version. But when manufacturers remove fat, they sometimes add sugar or starch to keep the taste and texture people like. What’s more, fat isn’t inherently unhealthy: certain types, including unsaturated fats from foods like nuts, seeds, avocados, and olive oil, can be part of a healthy diet.

Why health halos work so well

Health halos aren’t about willpower or how much you know about nutrition. They simply tap into normal shortcuts your brain uses to make fast decisions.

When you’re facing hundreds of choices in one aisle, your brain looks for quick signals. A single positive cue can shape your overall impression of a product. Researchers have studied this for years. A systematic review and meta-analysis published in the International Journal of Behavioral Nutrition and Physical Activity found that health-related claims on packaging have “substantial” influence on which foods people choose.

Halos may also affect how much we eat. In one small study published in Appetite, people ate about 35% more cookies when they were described as healthy than when the same cookies were described as indulgent. It was one experiment with a limited group, so it doesn’t prove this happens to everyone. Still, it hints at something many of us know from experience: When a food feels “good for you,” it’s easy to give yourself a pass on portions.

How to read labels more critically

You don’t need to give up your favorite packaged foods. You just need a few easy habits to decode them a little better.

Flip the package over.

Front-of-package claims are marketing. The nutrition facts label and ingredient list on the back give you the full story. Make that your first stop.

Use the % daily value as a shortcut.

The FDA suggests a simple rule: 5% Daily Value or less is low, and 20% or more is high. Aim higher for fiber, vitamin D, calcium, and potassium, and lower for sodium, saturated fat, and added sugars.

Check added sugars.

The label now listsadded sugars on their own line. TheAmerican Heart Association recommends no more than 25 grams of added sugar per day for women and 36 grams for men. This is especially handy for “natural” granolas, yogurts, and snack bars.

Check sodium.

Even foods that look healthy on the front of the package can pack in a lot of sodium. A quick glance at the % Daily Value can help you spot when a soup, snack, or frozen meal is much saltier than you might expect.

Look at the serving size

A snack can look modest until you realize the bag holds two or three servings. Compare the serving size to how much you’ll actually eat.

Scan the first few ingredients

Ingredients are listed by weight, from most to least. If sugar or refined flour shows up near the top, that tells you more than any front-of-pack claim.

Ask one simple question

Before you buy, ask yourself: “Would I still choose this without the claim on the front?” It’s a quick gut check that helps you see past the halo.

The bottom line

Labels like “organic,” “low-fat,” and “gluten-free” can be useful, but they rarely tell you the whole story about a food’s nutrition. Health halos work because they speak to real goals we all share, like eating well and taking care of our bodies.

You don’t have to be perfect, and you don’t need to fear packaged foods. A few extra seconds with the nutrition facts label can help you make choices that truly match your health goals, not just the marketing.
