Q&A: What are ultra-processed foods?
Nearly every day, there's a headline about ultra-processed foods, which have been linked to harmful health effects despite lacking a universally accepted definition. These foods are the subject of numerous proposed regulations, but they are not easy for consumers to avoid because they are common and often cheaper and more convenient than healthier alternatives.
Ultra-processed foods are a subject of much discussion and regulation, but few people truly understand what they are. These foods, defined by the presence of industrial additives like dyes, preservatives, and artificial ingredients, are common in our diets and often cheaper and more convenient than healthier alternatives. Kristina Petersen, an expert in nutritional sciences, sheds light on this topic in a Q&A session.
Petersen explains that ultra-processed foods include items like candies, cookies, chips, and processed meats. These items are distinct from foods processed for safety or longer shelf life, such as canned vegetables with added salt or pasteurized milk. The evidence shows that consuming more ultra-processed foods is linked to a higher risk of various health issues, including obesity, heart disease, type 2 diabetes, and certain cancers. Clinical trials also suggest that diets high in these foods can lead to overeating and weight gain.
Identifying ultra-processed foods can be tricky. While long, complex ingredient lists can raise suspicions, they can be misleading due to scientific names for harmless ingredients. Instead, Petersen recommends paying attention to the nutrition label, which highlights the amounts of added sugars, saturated fat, and sodium. If a product is high in these, it's advisable to seek healthier alternatives.
The prevalence of ultra-processed foods in the U.S. is significant, with children consuming over 60% of their daily energy from these foods and adults just over 50%. This high consumption, combined with the prevalence of diet-related chronic diseases and emerging research, has sparked calls for the food industry and government to limit these products.
Currently, the federal government is working on defining ultra-processed foods due to varying definitions among groups. Some states are also implementing regulations to limit ultra-processed foods and additives in school meals.
Food companies are responding to these pressures by reformulating products to eliminate additives, driven by the need to meet state-specific regulations while maintaining a broad market presence. This reformulation effort has led to products labeled as "no artificial colors," among others. Despite growing public interest in nutrition, driven by government attention, cost remains a barrier to healthier eating. Ultra-processed foods are often cheaper and more convenient, making them difficult to avoid.
Petersen advises that a healthy diet, rich in vegetables, fruits, whole grains, legumes, and nuts, should limit foods high in added sugars, saturated fat, and sodium. Ultra-processed foods, which include many junk foods like cookies, candies, sugary drinks, pizza, and processed meats, should be consumed sparingly as occasional treats.
Recognizing the barriers to a healthy diet, Petersen suggests that small, incremental improvements are more sustainable than drastic changes. Choosing fresh fruits and vegetables, even if they're more expensive or have additives, is preferable to skipping them altogether. Ultimately, even modest changes can lead to a healthier diet.
