Scientists Demand Urgent Action Against Ultraprocessed Foods in U.S. Diets

A group of international researchers is urging governments to take swift action against ultraprocessed foods. These products now dominate supermarket shelves, accounting for over 70% of items in U.S. grocery stores. Studies have linked them to serious health risks, including diabetes, obesity, and heart disease. The call for stricter policies comes as the U.S. prepares to update its federal dietary guidelines. For the first time, these guidelines may address ultraprocessed foods directly. Researchers suggest measures like taxes on sugary drinks, warning labels on packaging, and bans on marketing such products to children. Schools and hospitals could also remove ultraprocessed options from their menus.

Some countries have already made progress. Chile's warning labels and marketing restrictions have proven effective. But in the U.S., industry pushback has slowed similar efforts. The researchers also stress the need to make whole and minimally processed foods more affordable, particularly for low-income families. Not all ultraprocessed foods are unhealthy, and some minimally processed items fall under the same category. However, the focus remains on reducing those linked to chronic illnesses. No country has yet introduced the strictest controls on sales or advertising of these foods.

The upcoming U.S. dietary guidelines could mark a turning point in addressing ultraprocessed foods. If adopted, proposed policies may reduce consumption and improve public health. The success of such measures will depend on affordability, accessibility, and overcoming industry resistance.
