If you eat a lot of factory-processed foods, you might want to think about cutting back.
A new study has shown that for every 10% more highly processed food someone eats, there is a 12% bigger risk of them developing cancer.
Fizzy drinks, packaged breads and cakes, sweets, crisps, sausages, bacon, ham, instant noodles and frozen or chilled ready meals have all been linked to the disease.
The research, which was carried out by teams from the Sorbonne in Paris and the University of Sao Paolo, looked at 104,980 French adults with an average age of 43.
There was no major connection found between less processed foods (like canned vegetables, fresh bread and cheese) and cancer.
Foods like fruit, rice, pasta and fresh meat were associated with a lower overall risk of developing the disease.
