Colon cancer could be caused by certain types of cooking oils, a new study has warned. Oils like sunflower, canola, corn and grapeseed have been highlighted as oils of concern. The piece published in the medical journal Gut analysed 80 patients with colon cancers in the US.

It found the cooking oils increased the risk of developing colon cancer in the patients aged between 30 to 85. The research found people should swap seed oils for oils that contain omega-3 fatty acids like olive and avocado oil. Seed oils are responsible for higher levels of lipids that produce fat compounds in the body – and more than 25% of the calories in our diets come from eight seed oils: rapeseed, sunflower, flaxseed, corn, grapeseed, soybean, rice bran, and safflower.

These oils also lead to inflammation in the body because they contain omega-6 and polyunsaturated fatty acids. Tim Yeatman, a professor of surgery and lead author of the study, told Good Health: ‘Eating excess omega 6s results in excess pro-inflammatory lipid [i.e. fats] mediators, which results in an immuno-suppressed environment of the colon cancer.
‘And I think it allows [the cancer] to grow and prosper and propagate.’. He suggests swapping to oils with more omega 3s, like olive or avocado oil, adding: ‘Olive oil has many proven health benefits and is a central component in the Mediterranean diet consistently shown to be the healthiest eating pattern.
