Ultra-processed foods (UPFs) are packaged products containing ingredients not typically found in a kitchen, created by food technologists in factories. They are high in fat, salt, and sugar, with long shelf lives. Consuming diets high in UPFs can increase the risk of various health conditions, including heart disease, obesity, and cancer. However, not all processed foods are unhealthy, as some minimal processing is necessary even in home-cooked meals.

There are myths surrounding vegan UPFs, with misconceptions about their health benefits and environmental impact. While some vegan meat alternatives may be categorized as UPFs, they often contain less fat and no cholesterol compared to animal-based products. It is essential to focus on a variety of whole plant foods with minimal processing to maintain a balanced vegan diet.
