For years, we’ve been told that sugar is the primary enemy in our modern diets. We meticulously check labels for grams of sugar and feel guilty about dessert. But what if this intense focus on a single ingredient is causing us to miss the bigger, more complex picture? You clicked here because you suspect there’s more to the story, and you’re right.
It’s important to start by saying that the concern over excessive sugar consumption is valid. Diets high in added sugars, particularly from sources like sugary drinks, candy, and baked goods, are linked to a host of health problems. These sugars provide “empty calories” with little to no nutritional value, can contribute to weight gain, and lead to sharp spikes and crashes in blood sugar levels.
The American Heart Association recommends limiting added sugar to no more than 25 grams (6 teaspoons) per day for women and 36 grams (9 teaspoons) per day for men. Yet, the average American consumes significantly more. So, sugar is certainly not a health food, and reducing our intake of added sugars is a positive step.
However, blaming sugar alone is like blaming a single leaky pipe for a city-wide flood. It’s a visible part of the problem, but it distracts from the systemic issue that’s causing the real damage. The true culprit is not just one ingredient, but the industrial process that combines it with many others.
The real villain hiding in plain sight is the category of foods known as ultra-processed foods, or UPFs. This is a term used by scientists and nutrition experts, like those using the NOVA food classification system, to describe industrial formulations of food-derived substances.
Think of it this way:
UPFs are the dominant source of calories in many modern diets, and they are the delivery mechanism for the vast majority of the sugar we consume. But the sugar is just one component of a much more problematic package.
The problem with UPFs goes far beyond their sugar content. It’s the unique combination of their characteristics that makes them detrimental to our health.
1. They Are Engineered for Overconsumption Food scientists design UPFs to be “hyper-palatable.” They find the perfect combination of sugar, unhealthy fats, salt, and artificial flavors to bypass your body’s natural fullness signals. This is why it’s so easy to eat an entire bag of chips (a UPF) but much harder to overeat on baked potatoes (a whole food). Products like Doritos or Oreo cookies are classic examples of this food engineering.
2. They Lack Essential Nutrients and Fiber The industrial processing strips away many of the beneficial components of the original whole foods, especially fiber. Fiber is crucial for gut health, slowing down sugar absorption, and promoting feelings of fullness. A sugary breakfast cereal like Froot Loops, for example, is stripped of the fiber found in whole grains, leaving you with refined carbohydrates and sugar that your body absorbs almost instantly.
3. They Contain Unhealthy Fats and Additives To achieve a long shelf life and specific textures, UPFs often contain industrial fats like hydrogenated or interesterified oils. They also include a range of additives, such as emulsifiers, thickeners, and artificial colors and flavors. While approved for consumption, emerging research suggests some of these additives may negatively impact gut health and inflammation over the long term.
4. They Displace Whole Foods Perhaps the most significant impact of a diet high in UPFs is that it leaves little room for nutrient-dense whole foods. Every time you reach for a packaged snack, a frozen pizza, or a fast-food meal, you’re missing an opportunity to nourish your body with the vitamins, minerals, and phytonutrients found in fruits, vegetables, and lean proteins.
Learning to identify UPFs is the most powerful skill you can develop for improving your diet. They are designed to look appealing and are often marketed with health claims like “low-fat,” “made with whole grains,” or “added vitamins.”
Here’s how to spot them:
The takeaway is simple: instead of obsessing over the sugar column on the nutrition label, shift your focus to the ingredient list. The goal isn’t to eliminate sugar completely but to reduce your consumption of ultra-processed foods, which will naturally lower your sugar intake and improve your overall health. By focusing on the true source of the problem, you can make more meaningful and lasting changes to your diet.
Is all processed food bad? No. There is a huge difference between processed and ultra-processed. Canned beans, plain yogurt, frozen vegetables, and whole-grain bread are all examples of processed foods that can be part of a very healthy diet. The key difference is that they are still recognizable as food and have short, simple ingredient lists.
What about natural sugar in fruit? The sugar in whole fruit comes packaged with fiber, water, vitamins, and minerals. The fiber slows down the absorption of the sugar, preventing the dramatic blood sugar spikes associated with added sugars in UPFs. Eating whole fruit is overwhelmingly beneficial for your health.
Can I ever eat ultra-processed foods? Of course. A healthy diet is about balance and overall patterns, not perfection. The goal is not to eliminate UPFs entirely but to make them a small part of your diet rather than the foundation of it. Focus on making whole, minimally processed foods the star of your meals.
