"Introduction Ultra-processed foods, as defined using the Nova food classification system, encompass a broad range of ready to eat products, including packaged snacks, carbonated soft drinks, instant noodles, and ready- made meals. 1 These products are characterised as industrial formulations primarily composed of chemically modified substances extracted from foods, along with additives to enhance taste, texture, appearance, and durability, with minimal to no inclusion of whole foods. 2 "

What a vague definition that totally misses the specifics that matter. There's an overwhelming variety of food additives.

Do you know where they eat some of the most processed food in the world? Japan. Some of the highest life expectancy in the world.

What are they doing differently? Without knowing what exactly the commonalities are, there is no value to this study.
