Ultra-processed foods (UPFs) have been a contentious topic with varying degrees of misinformation presented to consumers. Dr. Nicola Guess, a Nutrition Scientist at Oxford University, emphasizes that not all UPFs are inherently unhealthy and that the health impact of processed foods depends on the specific type of food. The Nova classification system in the UK categorizes foods into groups based on processing level, but solely focusing on processing to determine a food's healthiness can be misleading. Some UPFs, like plant-based meats and dairy alternatives, have been shown to have potential health benefits, contrasting with the traditionally viewed unhealthy UPFs like sugary snacks and high-fat meals.

A recent study published in The Lancet found that certain processed foods, such as plant-based meats, bread, and cereals, were not associated with an increased risk of diseases like type 2 diabetes and cardiovascular issues. This suggests that the health impact of UPFs varies greatly depending on the specific food, rather than the degree of processing. Dr. Guess advocates for a more nuanced and scientifically accurate approach to understand the health implications of processed foods, challenging the blanket vilification of all UPFs as unhealthy.
