They often contain additives for flavor or preservation and are designed for convenience and long shelf life. The classification is part of the NOVA food classification system, which categorizes foods based on their level of processing.

What health risks are linked to these foods?

Consumption of ultra-processed foods is linked to various health risks, including obesity, heart disease, diabetes, and certain cancers. Studies suggest that diets high in these foods contribute to poor nutrition and chronic health conditions, as they often lack essential nutrients while being calorie-dense.

What percentage of calories come from these foods?

Recent reports indicate that more than half of the calories consumed by Americans—approximately 55%—come from ultra-processed foods. This statistic highlights a significant dietary trend that raises concerns about public health and nutrition.

How has consumption changed over time?
