The International Fruit and Vegetable Juice Association disagreed with the classification of reconstituted fruit juices as ultra-processed foods (UPF) in a Lancet series article by Carlos Monteiro and colleagues on ultra-processed foods and human health[1]. The association asked the authors to re-evaluate this classification given in panel 1 of the overview of the mentioned article. The correspondence was sent in response to scientific findings regarding the link between ultra-processed foods and damage to major organ systems in the human body[1]. The article concerns the contradiction between the scientific classification of foods according to the NOVA system and the position of the industry that produces fruit juices[6]. Reconstituted fruit juices are foods made from concentrate or dried fruit dissolved in water, which places them in the category of processed products[2]. This correspondence is an example of the debate between scientists and industry about how to properly classify foods based on their degree of processing and health impact.
