It’s cheap, attractive and convenient, and we eat it every day – it’s difficult not to. But is ultra-processed food making us ill and driving the global obesity crisis?
Ultra-processed foods (or UPF) now account for more than half of all the calories eaten in the UK and US, and other countries are fast catching up. UPFs are now simply part of the flavour of modern life. These foods are convenient, affordable, highly profitable, strongly flavoured, aggressively marketed – and on sale in supermarkets everywhere.
You might say that ultra-processed is just a pompous way to describe many of your normal, everyday pleasures. It could be your morning bowl of Cheerios or your evening pot of flavoured yoghurt. It’s savoury snacks and sweet baked goods. It’s chicken nuggets or vegan hotdogs, as the case may be. It’s the doughnut you buy when you are being indulgent, and the premium protein bar you eat at the gym for a quick energy boost. It’s the long-life almond milk in your coffee and the Diet Coke you drink in the afternoon. Consumed in isolation and moderation, each of these products may be perfectly wholesome. With their long shelf life, ultra-processed foods are designed to be microbiologically safe. The question is what happens to our bodies when UPFs become as prevalent as they are at the moment.
Evidence now suggests that diets heavy in UPFs can cause overeating and obesity. Consumers may blame themselves for overindulging in these foods, but what if it is in the nature of these products to be overeaten?
