Ultra-processed foods: nutritional complexity and health guidelines

The debate surrounding ultra-processed foods highlights a need for a nuanced understanding of food technology and nutrition. While the NOVA classification categorizes these items based on additives, food technologists note that this can lead to oversimplification. Some products labeled as ultra-processed may actually provide essential benefits, such as food safety, microbiological stability, nutrient fortification, and increased accessibility.

Experts suggest that not all processed foods are equal. For instance, certain plant-based or fortified products may fall into the ultra-processed category despite offering beneficial fiber, proteins, and micronutrients. Rather than focusing solely on the degree of processing, researchers emphasize evaluating the overall nutritional profile and context of use.

Regarding consumption limits, there is no universal threshold that guarantees zero risk. However, health guidelines, such as those from the French Assurance Maladie, recommend limiting ultra-processed foods to less than 15% of total caloric intake. Experts suggest prioritizing whole or minimally processed foods and maintaining dietary diversity to prevent nutritional imbalances.
