You might think you’re making smart choices when you grab that granola bar or pour yourself a morning glass of orange juice. We’ve all been there, convinced we’re doing our bodies a favor by choosing what seems like the healthier option. Honestly, I’ve fallen for the same tricks too.
The thing is, some of these so-called “healthy” foods might not be quite what they appear to be. Let’s be real: the food industry has gotten pretty clever at making products seem nutritious when they’re actually loaded with stuff we’d rather avoid. Recent research from the past few years has started pulling back the curtain on foods that nutritionists themselves are now questioning.
Ultra-Processed Protein Bars and Shakes
Multiple nutritionists agreed in late 2024 that ultra-processed protein bars and shakes should be left behind, especially those with artificial sweeteners and inflammatory ingredients. Here’s the thing about these convenient snacks: they might promise a quick protein fix, but what else are you getting?
Nearly 60% of the calories Americans consume come from ultra-processed foods, and recent research published in the British Medical Journal suggests that diets high in these foods are linked to dozens of health problems, including heart disease, Type 2 diabetes, cancer and mental health conditions. Think about that for a second. A 2024 review of 45 metanalyses, covering nearly 10 million study participants, found convincing evidence that a diet high in ultra-processed foods increases the risk of death from cardiovascular disease by 50% and the risk of anxiety by 48%.
Ultraprocessed foods typically contain a long list of ingredients, most of which are not used in home cooking and would be more familiar in a chemistry lab. When you check the label on that protein bar, you’re probably seeing words you can’t even pronounce. They contain ingredients you wouldn’t find in a typical kitchen, like emulsifiers, colorings, flavor enhancers, bulking agents, gels, and tend to be higher in saturated fat, higher in salt and higher in sugar.
Flavored Yogurt
Walk down the yogurt aisle and you’ll see rows of colorful containers promising fruity deliciousness. Seems innocent enough, right? Not exactly. Nutritionists warned about flavored yogurts due to added sugars and flavorings, with one serving potentially having the equivalent of five to six added teaspoons of sugar.
Let me put that into perspective for you. That single serving of strawberry or vanilla yogurt you’re eating for breakfast could be packing more sugar than you should consume in an entire day. The problem isn’t the yogurt itself – it’s what manufacturers add to make it taste like dessert.
The new dietary guidelines take a strict position on sweets, noting that no amount of added sugars or non-nutritive sweeteners is recommended or considered part of a healthy or nutritious diet. Nutritionists recommend trying plain yogurt with fresh fruit instead. Sure, it takes a bit of getting used to, but your body will thank you.
Artificially Sweetened Diet Products
I know what you’re thinking – surely diet soda and foods with artificial sweeteners are better than their sugary counterparts, right? Well, that’s where things get complicated. Although artificial sweeteners have zero calories, they may have the opposite effect on weight loss goals due to multiple factors including gut health and insulin response, potentially altering the gut microbiome which affects nutrient absorption, metabolism, and regulation of glucose.
High consumption of artificial sweeteners has been associated with increased risks of metabolic disorders, cardiovascular diseases, certain cancers, and paradoxically weight gain, with studies including the Women’s Health Initiative linking artificially sweetened beverages to an elevated risk of stroke, coronary heart disease, and mortality, independent of established risk factors. This is pretty shocking when you consider how many people switch to diet products thinking they’re making the healthier choice.
Some research on long-term, daily use of artificial sweeteners suggests a link to a higher risk of stroke, heart disease and death overall, though other things people do, or healthy habits that people don’t do, may be the cause of the higher risk. Concerns extend to gut health, where artificial sweeteners like saccharin have been linked to inflammatory bowel diseases, gut microbiota disruption, increased intestinal permeability, and dysbiosis, leading to metabolic disturbances such as impaired glucose tolerance, insulin resistance, and heightened systemic inflammation. Your gut bacteria basically don’t know what to do with these synthetic compounds.
Store-Bought Fruit Juice
Here’s one that might surprise you. While you may think 100% fruit juice is healthy, it may spike your blood sugar and remove one of the fruit’s greatest benefits: fiber, turning the perfect food into something more like sugary soda in terms of the biochemical effects on metabolism. Yeah, you read that right – fruit juice can be just as problematic as soda.
An eight-ounce serving of juice and cola both contain about 30 grams of sugar on average, almost eight teaspoons, and most commercial juice eliminates wholesome fruit parts like skin and pulp, which are important sources of fibre and nutrients. It might take the juice of five or six oranges to fill a cup, resulting in a lot of sugary fluid, which can cause an immediate spike in blood sugar levels. Think about how many whole oranges you’d actually sit down and eat – probably just one, maybe two.
Processing and storing 100% fruit juice reduces its fibre, vitamins and other antioxidant contents and transforms intrinsic sugars in the whole fruit into free sugars, with the nutrient composition differing significantly from whole fruits, particularly being high in free sugars. The high sugar and low fiber content of juice means that it can spike blood sugar levels and increase your appetite, and over time, this combination can lead to weight gain.
Foods with “Natural Flavors”
Foods with the words “natural flavors” in their ingredient lists were flagged by nutritionists, as despite the name, natural flavors are often just as processed as artificial ones, created by flavorists who are scientists hired to craft and manipulate flavors in a lab, and while they may sound better, natural flavors can still mess with your gut, trigger cravings and offer no real nutritional benefit.
Let that sink in for a moment. The word “natural” on a label doesn’t actually mean what you think it means. These flavor compounds are engineered in laboratories to make processed foods taste better and keep you coming back for more. Natural flavors are vague and can be highly processed.
Some “healthy” foods may contain high amounts of hidden unhealthy fats, sugars and sodium that could lead to weight gain, high blood pressure and high cholesterol, and it’s essential to be aware of these potential culprits and make informed choices when it comes to food products marketed as ‘healthy.’ The marketing teams know exactly which buzzwords to use to make you feel good about buying their products.
Organic Packaged Snacks
Cookies, chips and other snacks labeled as “organic” may give the impression that they’re healthier than they are, but these items are often just as high in sugar, unhealthy fats and calories as non-organic versions, and they also likely lack essential nutrients, like vitamins, minerals and fiber. I hate to break it to you, but organic junk food is still junk food.
Annie’s Organic Cheddar Bunnies contains 140 calories per 51 crackers with 260 milligrams of sodium, 6 grams of fat and 18 grams of carbs, while Pepperidge Farm’s Goldfish Original crackers have 140 calories per 55 crackers with 6 grams of fat, 230 milligrams of sodium and 20 grams of carbs. See what I mean? The nutritional profiles are remarkably similar.
The organic label tells you about how the ingredients were grown, not whether the food itself is good for you. Many packaged foods make claims like low-sugar, high-fiber, plant-based or organic that seem to suggest healthfulness, but these items are sometimes not actually nutritious, and many of these terms give the packaged food a health halo, but when you look closer at the ingredient list and nutrition facts panel, it may reveal that it is not a nutritious choice after all.
So what’s the takeaway here? Nearly all health experts try to replace items like cookies, crackers and deli meats with vegetables, fruits and whole grains, really trying to do a whole foods approach, with the rule that if having dinner or lunch, trying to make everything not come out of a package, such as chicken breasts with broccoli and rice. It’s not about being perfect – it’s about being aware and making better choices when you can. Did these revelations catch you off guard? What do you think about the foods on this list?
