Many people are shocked to learn that some of the foods they rely on every day are labelled as unsafe under the NOVA classification system. This system, which sorts foods by the degree of processing, has become a popular guide for judging what is healthy and what is not. However, upon closer examination of how NOVA categorizes foods, it becomes clear that many foods classified as ultra-processed are not the villains they are often portrayed to be. In fact, many of these foods play a crucial and beneficial role in daily nutrition. Understanding this gap between classification and reality is essential for anyone who wants to make informed food choices.
Start with wholemeal bread as a base. NOVA categorizes most packaged breads as ultra-processed, primarily because they contain additives such as raising agents or emulsifiers. It gives the impression that these breads are harmful. The evidence tells a different story. Bread remains a significant source of fibre, iron, magnesium, and B vitamins in many national diets. Wholemeal bread, in particular, supports digestive health, provides slow-release energy, and contributes essential nutrients that many people struggle to get enough of. Labelling it unsafe because it is sliced and packaged ignores what really matters for health, which is the nutrient content and how often it is eaten.
Yogurt is another surprising example. Flavored yogurts, even those with added fruit or live cultures, are often categorized as ultra-processed. Yet, yogurt provides calcium, protein, and probiotic benefits that contribute to both bone health and gut health. It is also widely consumed by children and older adults, two groups that benefit greatly from its nutrient profile. Calling these yogurts unsafe based solely on processing steps overlooks their clear nutritional value.
Breakfast cereals also fall victim to this broad classification. Many cereals are fortified with vitamins and minerals that support public health goals. People who eat breakfast cereals often achieve better overall nutrient intake, including higher levels of iron, folate, and B vitamins. Yet NOVA groups these cereals together with foods high in sugar or low in nutritional value, creating confusion rather than clarity.
These examples highlight a critical issue. The NOVA system focuses on the presence of processing rather than the nutritional quality of the final food. This approach oversimplifies complex nutritional science and can mislead consumers into avoiding foods that support their health. What truly matters is the balance of nutrients in the diet, not whether a food is sliced, packaged, or fortified.
For a deeper, evidence-based look at how these misconceptions spread and why they matter, In Defence of Bread by Mike Gibney offers a clear and valuable explanation.
