New ZOE Score Redefines Ultra-Processed Food Risks, Challenging Traditional Classifications
New research from ZOE, led by Professor Tim Spector and Professor Sarah Berry, is challenging the traditional NOVA classification of ultra-processed foods (UPFs) by introducing a more nuanced 'Processing Food Score.' While the NOVA system broadly classifies 60% of U.S. and UK diets as UPF, the ZOE score identifies only about 25% of calories consumed as 'high-risk' processed food. This new score incorporates three key features: the number and potential health risk of additives, the energy intake rate (how fast food is eaten), and the hyperpalatability index (the 'bliss point' of fat, salt, and sugar combinations). The ZOE research indicates that not all processed foods are equally detrimental; for instance, some dark chocolates, nutty granolas, and whole-grain cereals previously classified as UPF under NOVA are deemed low-risk by the ZOE score. This distinction is crucial because the NOVA classification, while useful for broad research, often over-demonizes many foods that may not pose significant health th...
