Revolutionary New Method for Classifying Processed Foods: What Scientists Discovered

Recent years have sparked a lively debate about processed foods. People are more curious than ever about how these foods affect our health, but researchers have found it challenging to pinpoint exactly which processing factors matter most.

A new system from WISEcode aims to change that. This team has developed a way to classify processed foods based on their health impacts, helping consumers make informed choices.

Richard Black, PhD, a key figure at WISEcode, explained, “Our method is more detailed and objective than older systems. It gives consumers a clearer way to assess processed foods.” This app allows users to compare products easily, making healthier choices even amid a sea of processed options.

The common classification system known as Nova, introduced in 2009, sorts foods into four categories. While it helps raise awareness about food processing, it lumps many products together. For example, a candy bar and a sugar-free breakfast cereal can end up in the same category. This makes it tough to assess a specific food’s health impacts.

Black noted that “Nova’s broad definitions don’t reflect the complexity of modern food. Some processed foods might be harmful in the long run, but others could actually fit into a healthy diet.”

To address this challenge, WISEcode’s scoring system assesses three components: the health risks of ingredients, the percentage of calories from added sugars, and any known health concerns associated with specific ingredients. This approach offers more distinction among ultra-processed foods, which is where many health concerns lie.

In tests comparing over 650,000 foods, WISEcode showed clearer differences than Nova could provide. Foods are now categorized into five levels of processing: minimal, light, moderate, ultra, and super-ultra. Surprisingly, 16–23% of foods fall into each of these categories, revealing a mix in the ultra-processed group.

Looking ahead, Black emphasized that this work is still evolving. “Our system is built to adapt as we learn more about ingredients and processing,” he said. This ongoing research will keep information current, providing valuable insights for consumers and researchers alike.

In parallel, data from recent studies highlights growing concerns about processed foods. A survey by the Centers for Disease Control and Prevention (CDC) found that nearly 40% of U.S. adults consume junk food daily, emphasizing the need for better classification systems to guide healthier choices.

As debates continue, tools like WISEcode can empower consumers and help food producers understand the link between ingredients and health risks.
