Colon cancer cases are increasing among young Americans, and one of the major risk factors could be the use of popular cooking oils in ultra-processed diets, a new US government-backed research, published in Gut Journal has found out.
In a striking discovery, the study analysed the tumors from over 80 colon cancer patients, and identified seed oils to be the potential culprits behind colon cancer, which has been one of the fastest-growing cancers in recent times.
These tumors were loaded with high concentrations of bioactive lipids, which are tiny greasy substances that were found to accumulate during the metabolic breakdown of seed oils.
Eating foods high in sunflower, canola, corn, and grapeseed could trigger inflammation in the body which could lead to the development of cancer. Chronic inflammation can also lead to heart conditions, arthritis, metabolic syndrome, or stroke.
Seed oils are refined vegetable oils that come from plant seeds, rather than the fruit. They are neutral in taste and have a high smoke point. Some common seed oils include:
Canola oil, Corn oil, Sunflower oil, Grapeseed oil, Safflower oil, Rapeseed oil, Soybean oil, Peanut oil, Linseed oil, and Castor oil.
Seed oils are often used in processed foods to provide flavor and shelf stability. While they can be a good source of omega-3 and omega-6, some research suggests that the trace amounts of omega-6 in seed oils are unlikely to harm health.
Seed oils are highly refined and processed with bleaching, deodorizing, and heating, which can lead to the creation of harmful compounds. When heated at high temperatures and used in deep-frying or cooking at high heat, they may undergo oxidation, producing potentially toxic byproducts like aldehydes.
These toxic compounds can damage tissues and contribute to aging and chronic diseases, increase the risk of cancer, and lead to insulin resistance. Besides, the refining process can also increase trans fat content which can lead to heart disease, high cholesterol, and high blood pressure. It can also lead to weight gain.
Findings of the study
The study probed 81 tumor specimens from individuals between 30 to 85 years old.
These tumor samples contained significantly higher levels of oil-induced lipids compared to those derived from healthier fats within their malignant growths.
These lipids are notorious for increasing levels of inflammation, aiding tumor proliferation, and hindering the body’s anti-cancer defenses.
This is the right oil to prevent colon cancer
The team of scientists has advised switching to oils with omega-3 fatty acids which are found in olive or avocado oil to prevent cancer risk.
A diet low in fibre, high red meat consumption, especially processed meats, being overweight or obese, alcohol consumption, smoking tobacco, inherited genetic risk and family history, inflammatory bowel disease such as Crohn’s disease, polyps, and having a previous diagnosis of bowel cancer are some of the common causes of bowel cancer.
