Some ultra-processed foods increase the risk of developing cancer, heart disease and diabetes – but others are good for you, new research into the demonised foodstuffs suggests. |
A major new international study has found that regular consumption of meat products – such as sausages – and sugary drinks make it more likely that someone will get those diseases. |
But bread and cereals actually reduce someone’s risk of them – because they contain fibre – despite also being ultra-processed foods (UPF), the same researchers also concluded, in findings published in The Lancet. |
Similarly, sauces, spreads and condiments are also bad for human health, but not as much as animal products and soft drinks. |
However, several other major types of UPF previously seen as harmful: sweets and desserts, ready meals, savoury snacks and plant-based alternatives to meat products also got the all-clear. They are “not associated with risk of multimorbidity”, said the authors. |
Experts said the findings showed that regarding all UPF products as bad for health is unwise and unwarranted. |
Like several other recent research projects, the new study did conclude that UPF harms human health and makes it more likely that someone who consumes a lot of it would suffer a potentially fatal event, such as a heart attack or stroke. However, it also gives a more detailed picture of exactly which UPF products do and do not heighten that risk. |
The latest study is based on an analysis of the dietary history of, and illnesses experienced by, 266,666 people in seven European countries, including the UK. |
The authors said: “In this multinational European prospective cohort study, we found that higher consumption of UPF was associated with a higher risk of multimorbidity of cancer and cardiometabolic diseases.” |
People keen to lower their risk should replace some but not all UPF in their diet with “similar but less processed foods … for the prevention of cancer and cardiometabolic multimorbidity” or follow the Mediterranean diet, they said. |
Multimorbidity is when someone has at least two life-shortening diseases at the same time, such as cancer and heart disease. |
Heinz Freisling, a co-author of the paper and expert at the World Health Organization’s cancer research agency IARC, which also collaborated on the study, said: “Our study emphasises that it is not necessary to completely avoid ultra-processed foods; rather, their consumption should be limited, and preference be given to fresh or minimally processed foods.” |
