It’s Too Complicated.There’s no real evidence that a pizza made at home is better than a frozen store-bought one with the same ingredients.BloombergPublished22 Mar 2025, 05:47 PM ISTWhat Counts As Ultra-Processed Food? It’s Too Complicated. (Bloomberg Opinion) -- Ultra-processed foods, or UPFs for short, are suddenly the hot health concept — the new antihero in global diets. The topic is exploding both in scientific literature and on social media. There’s even an AI system to help consumers select less-processed foods while shopping. But once you get past the important and obvious idea that junk food is harmful, the concept of ultra-processed becomes hazy and confusing. There’s unprocessed, processed, culinary ingredients and ultra-processed. So, what’s the consumer supposed to do? NOVA, the most widely used system for categorizing food as ultra-processed, includes everything from doughnuts to frozen dinners. The unprocessed category includes fresh vegetables; culinary ingredients include things such as sugar, cooking oil and flour. Then there are the merely processed items, which include things like canned chickpeas, pasteurized milk and plain yogurt. Under this system, a frozen dinner made with healthy ingredients such as fish and broccoli might fall into the ultra-processed category, but not a homemade cake with lots of sugar. There’s no real evidence that a pizza made at home is better than a frozen store-bought one with the same ingredients. And if it’s the ingredients that matter, wouldn’t consumers be better off with a science-based guide to which ingredients are harmful? The ultra-processed classification system comes from Brazil, where Nestlé, sensing the market potential, flooded the country with packaged food. What followed was a corresponding increase in obesity and diabetes, although food industry executives justified the action by pointing out that the move decreased hunger. Telling people to avoid ultra-processed foods is a big improvement compared to simply advising them to avoid high-fat foods and eat low-fat versions of things like yogurt, ice cream, energy bars and cereal — which are usually high in sugar. Agreement on the dangers of a diet high in sugar is a rare area of common ground in the contentious science of nutrition. The medical community could go a long way in improving Americans’ health by helping them cut back in this area. From there, it’s important to keep studying which is the biggest threat posed by ultra-processed foods — whether it’s in the oils, the additives or the processing itself. Many ultra-processed foods are popular because they have a long shelf-life, tend to be cheaper and are convenient for people who don’t have time to cook. Scientists could help alleviate some chronic diseases and food insecurity by figuring out how to make the convenience foods we love healthier. More scientific research is also needed to determine which of the so-called ultra-processed foods are the worst for us. The best case against ultra-processed food comes from several studies that followed large populations and found correlations between the heavy consumption of these foods and poor health outcomes, including more heart disease and cancer. The same group also tends to have lower incomes, smoke, and lead more sedentary lifestyles, so epidemiologists must try to tease out all these factors. One of the most influential studies confined test subjects to a food lab for several weeks and monitored everything they ate. The results were mixed. People gained weight on higher-calorie ultra-processed foods — chicken nuggets, fries, sugary drinks — that are considered “hyper-palatable” because they taste good. They lost weight eating other ultra-processed foods like liquid eggs, flavored yogurt and oatmeal, turkey bacon, and burrito bowls with beans. The conclusion: The category of ultra-processed alone wasn’t enough to predict health outcomes, even in the short term. Another recently released study attempted to use brain scans to test the popular theory that ultra-processed foods are addictive and give people a dopamine surge similar to cocaine. The research found no such correlation, though the authors contend that this doesn’t disprove the addictiveness of foods. I was skeptical of the dogma that ultra-processed foods taste better than homemade — something that would obviously depend on the skill of the person doing the cooking. Everyone I know prefers homemade food, and home-cooked items always go first at potlucks I’ve attended. Dariush Mozaffarian, director of the Food is Medicine Institute at Tufts University agreed that homemade dishes are often tastier than the store-bought equivalents. But in some ways, they’re less satisfying, he said, and might therefore compel people to eat more not out of pleasure but some other impulse. He’s looking into the health effects of some of the ingredients that regularly show up in ultra-processed foods, such as artificial emulsifiers. These ingredients make ice cream and mayonnaise creamy but might also have a deleterious effect on our microbiomes — the bacteria that live in our guts. Others have pointed to the cheap fats used in ultra-processed foods — especially soybean oil. That’s been the subject of a longstanding war between epidemiologists, who say soybean oil is good for us, and some biochemists, who see excess amounts of these oils interfering with our body’s ability to use and incorporate healthy omega-3 fatty acids. The biochemists point to the dramatic rise in industrial oils in the 20th century and wonder if we’re still guinea pigs in an ongoing experiment. For years, we were told that the saturated fat found in many unprocessed foods such as whole milk, full-fat yogurt, cheese and meat caused heart disease. But several newer analyses of the scientific literature call that link into question. Mozaffarian points to new studies showing that people who eat full-fat dairy products are healthier than those who choose low-fat or nonfat versions. Another recent study showed an association between longevity and the consumption of vegetable oils and a slight decrease in longevity associated with butter, but only in people who were already unhealthy and not if the butter was used for cooking and baking. It was hard to know what conclusion to draw. Others are looking at the processing itself. Laszlo Barabasi, a network scientist at Northeastern University, said most plants and animals contain the same ratio of basic nutrients — fats, carbohydrates, protein and vitamins. In his theory, the more a food product deviates from that natural ratio, the more ultra-processed it is. Using that concept, his group trained an AI system to examine the proportions of 15 components listed on food labels to determine where they fall on an ultra-processed food spectrum. This could be useful in future studies but hasn’t yet been connected with specific health impacts. Food is personal, and scientists’ views get tied up in their environmental, ethical and spiritual feelings, especially on the choice between eating unprocessed meat and dairy and more processed meat substitutes. On the bright side, multiple lines of evidence show most of us would be healthier eating less sugar. That’s a good start. And then we need more and better research to sort out the rest.
