A study published in Nature Medicine found that ultra-processed foods (UPFs) could obstruct weight loss efforts, even when diets align with national healthy-eating guidelines. The research highlights a gap in the UK's dietary recommendations regarding UPFs. High salt and sugar levels contribute to their unhealthiness, but processing methods may also play a role. UPFs account for over half of the average diet in the UK, with affordability influencing their consumption, particularly among low-income populations. The study involved 55 adults following a UPF diet based on UK guidelines.
Ultra-processed foods (UPFs) may inhibit weight loss despite adherence to national healthy-eating recommendations, highlighting a lack of focus on their impact in dietary guidelines.
More than half of the energy in the average diet in the UK comes from UPFs, with socioeconomic factors playing a significant role in dietary habits.
The study revealed that unhealthy diets are often a result of an unhelpful food environment rather than a lack of effort in trying to eat healthily.
This trial is significant as it represents the longest-ever study of UPF diets in a real-world setting, incorporating everyday behavioral influences.
