Women Who Eat Ultra-Processed Foods Face Higher Bowel Cancer Risk

According to a study funded by the Cancer Grand Challenges research initiative, women who consume high amounts of ultra-processed foods (UPFs) are at a significantly higher risk of developing early-onset adenomas, a type of growth that can potentially lead to bowel cancer. The study analyzed data from 29,105 women with an average age of 45, and identified 1,189 cases of these early-onset adenomas.

The findings reveal that women with the highest UPF consumption were 45% more likely to have these adenomas compared to those with the lowest UPF intake. Ultra-processed foods are commercially manufactured products that have undergone extensive industrial processing, often containing added sugars, oils, refined carbs, and various additives.

To help people understand and reduce their UPF consumption, Rosie Carr, a dietitian at the healthy eating plan Second Nature, provided some practical advice. She suggests starting with gradual, sustainable swaps, such as replacing breakfast cereal with porridge and fruit, or swapping crisps for a handful of nuts. Carr also recommends reading ingredient lists, preparing simple meals in advance, and choosing minimally processed convenience foods like tinned beans, frozen veggies, and pre-cooked rice.

The key is to focus on gradually increasing whole foods rather than strictly avoiding UPFs, as this tends to lead to more sustainable changes in eating habits. While completely eliminating UPFs may not be realistic for most people, even replacing 20% of them with whole foods can provide meaningful health benefits.
