A recent study published in a cancer journal tracked 30,000 women over twenty years and found a correlation between high intake of ultra-processed foods and the development of colorectal polyps. These polyps are considered a main precursor to early onset colorectal cancer, a condition that has been rising among young adults.

While the study highlights a potential link, researchers caution that it does not establish a direct cause and effect relationship. Medical experts recommend minimizing consumption of ultra-processed foods and opting for whole, fresh foods, as further research is needed to clarify the role of diet among other cancer risk factors.

Eating ultra-processed foods linked to early colorectal cancer

It's fast, it's easy, but ultra-processed food might be a major health threat. A new study published Thursday in a cancer journal looked at 30,000 women over two decades. It found a link between eating a high level of ultra-processed foods and developing colorectal polyps. And these are the kinds of polyps that we believe are the main precursor lesion to the vast majority of early onset colorectal cancers. The lead researcher says the finding offers a key clue to what's behind an alarming trend – the rise in young adults developing colorectal cancer. We did expect that there might be some associations here, given that we are also seeing dramatic increases in our consumption of ultra-processed food. It's a big category of foods that are both highly processed and full of preservatives – items like mass-produced bread, many breakfast cereals or instant soup. So ultra-processed food is sort of that ready-to-eat, ready-to-heat type food. This Toronto oncologist praised the new study and said these products have long been known as less healthy options. They don't contain a lot of fibre, they have sort of the bad types of fats in them. Still this new finding isn't clear cause and effect. More research is needed to see where ultra-processed foods fit alongside other well-known cancer risk factors like obesity and a lack of physical activity. Joshua Kluskovec hopes scientists figure it out. The 34-year-old doesn't know what caused his stage 4 colon cancer, which has spread to his liver, lungs and bones. You're trying to stay as positive as you can, just hoping for a miracle to happen. After years of trying to lead a healthy lifestyle, he still has more questions than answers. You think, what else could I have done? Why am I now getting this diagnosis? Doctors and dieticians say one thing is clear, avoid ultra-processed foods as much as you can and when possible, choose whole, fresh foods instead. Lauren Pelley, CBC News, Toronto.
