Research Suggests High Ultra-Processed Food Intake May Contribute to Rising Bowel Cancer in Young Women.
A recent study published in the journal Jama Oncology has found a link between high consumption of ultra-processed foods and an increased risk of abnormal bowel growths that can lead to cancer in women under 50. The research, conducted by Massachusetts General Hospital researchers, analyzed data from over 29,000 female nurses who had completed a food questionnaire every four years.
Ultra-processed foods, often considered ready-to-eat industrial products with little whole foods, fibre, and vitamins, are high in saturated fat, sugar, salt, and additives. Studies have previously linked these foods to various health issues, including heart disease and early death. The researchers aimed to investigate the connection between ultra-processed food intake and rising rates of bowel cancer in younger people.
The study found that women who consumed more ultra-processed foods had a 45% higher risk of developing conventional adenomas, a common type of bowel polyp, compared to those who ate fewer of these products. However, there was no significant association with the development of serrated lesions, another type of polyp.
Researchers believe several mechanisms may explain the results, including metabolic disorders linked to obesity and type 2 diabetes, chronic inflammation, and impacts on gut microbes and the gut lining. While the study did not directly measure cancer risk, it provides insight into how diet can influence early changes in the bowel that sometimes lead to cancer.
Cancer experts emphasize that while policy-level changes are necessary to make healthier diets more accessible, overall diet plays a more significant role in cancer risk than any single food type.
