“This is the science behind how UPF affects the human body: • The destruction of the food matrix by physical, chemical and thermal processing means that UPF is, in general, soft. This means you eat it fast, which means you eat far more calories per minute and don’t feel full until long after you’ve finished. It also potentially reduces facial bone size and bone density, leading to dental problems. • UPF typically has a very high calorie density because it’s dry, and high in fat and sugar and low in fibre, so you get more calories per mouthful. • It displaces diverse whole foods from the diet, especially among low-income groups. And UPF itself is often micronutrient-deficient, which may also contribute to excess consumption. • The mismatch between the taste signals from the mouth and the nutrition content in some UPF alters metabolism and appetite in ways that we are only beginning to understand, but that seem to drive excess consumption. • UPF is addictive, meaning that for some people binges are unavoidable. • The emulsifiers, preservatives, modified starches and other additives damage the microbiome, which could allow inflammatory bacteria to flourish and cause the gut to leak. • The convenience, price and marketing of UPF urge us to eat constantly and without thought, which leads to more snacking, less chewing, faster eating, increased consumption and tooth decay. • The additives and physical processing mean that UPF affects our satiety system directly. Other additives may affect brain and endocrine function, and plastics from the packaging might affect fertility. • The production methods used to make UPF require expensive subsidy and drive environmental destruction, carbon emissions and plastic pollution, which harm us all.”
