Ultraprocessed Foods Linked To Heart Disease, Diabetes, Mental Disorders and Early Death, Study Finds

Eating ultraprocessed foods raises the risk of developing or dying from dozens of adverse health conditions, according to a new review of 45 meta-analyses on almost 10 million people. From a report: 'We found consistent evidence linking higher intakes of ultra-processed foods with over 70% of the 45 different health outcomes we assessed,' said senior author Wolfgang Marx, a senior research fellow at the Food & Mood Centre at Deakin University in Geelong, Australia, in an email. A higher intake was considered about one serving or about 10% more ultraprocessed foods per day, said Heinz Freisling, a scientist in the nutrition and metabolism branch of the World Health Organization's International Agency for Research on Cancer, in an email.

'This proportion can be regarded as 'baseline' and for people consuming more than this baseline, the risk might increase,' said Freisling, who was not involved in the study. Researchers graded each study as having credible or strong, highly suggestive, suggestive, weak or no evidence. All the studies in the review were published in the past three years, and none was funded by companies involved in the production of ultraprocessed foods, the authors said. 'Strong evidence shows that a higher intake of ultra-processed foods was associated with approximately 50% higher risk of cardiovascular disease-related death and common mental disorders,' said lead author Dr. Melissa Lane, a postdoctoral research fellow at Deakin, in an email. Cardiovascular disease encompasses heart attacks, stroke, clogged arteries and peripheral artery disease.
