Consumption of ultra-processed foods and drink could increase the risk of developing colorectal cancer. This was the conclusion of a large study undertaken by the Barcelona Institute for Global Health (ISGlobal), a center supported by the “la Caixa” Foundation, based on questionnaires about food behaviors completed by around 8,000 people in Spain. The study, the first of its kind in the country, also analyzed the relationship between ultra-processed food and drink products and two other cancers; while no association was observed with prostate cancer, in the case of breast cancer a higher risk was observed in the sub-group of former and current smokers who reported a diet high in ultra-processed products.
