    Study links common cooking oils from corn and sunflower seeds to increased colon cancer risk


    The foods we eat might be influencing our body’s ability to fight off cancer, particularly colorectal cancer, according to a groundbreaking study published in Gut, the journal of the British Society of Gastroenterology.

    Researchers have identified a troubling link between high levels of omega-6 fatty acids in modern diets and an increased risk of inflammation that may promote tumor growth, especially in the colon.

    Omega-6 fatty acids, commonly found in seed oils like soybean, corn, and sunflower, are prevalent in ultra-processed foods that dominate the Western diet. These fats are essential for health, playing roles in skin and hair growth, metabolism, and bone health. However, when consumed excessively, omega-6s can be converted into molecules that promote prolonged inflammation—a key factor in cancer development.

    “Our bodies are constantly experiencing mutations in the gastrointestinal tract, and the immune system, with the help of molecules derived from omega-3 fatty acids, typically eliminates these threats,” Dr. Timothy Yeatman, senior coauthor of the study and surgical oncologist at the Tampa General Hospital Cancer Institute, said to CNN. “But when there is a chronic imbalance—too much omega-6 and too little omega-3—the body’s defenses falter, allowing mutations to take hold and tumors to thrive.”

    Modern diets aren’t helping
    The imbalance of omega-6 to omega-3 fatty acids is stark in many modern diets. Historically, humans consumed these essential fats in roughly equal proportions. However, the rise of industrialized food production has skewed this balance.

    Over the past half-century, the amount of omega-6 in American diets has surged by 136%, largely due to the widespread use of inexpensive seed oils in fried and packaged foods. Conversely, the intake of omega-3—found in fatty fish, flaxseeds, and walnuts—has diminished significantly, as dietary patterns shifted away from fresh, nutrient-rich foods.

    Cancer rates are rising
    The shift toward ultra-processed foods and away from traditional diets has had devastating consequences for public health. Colorectal cancer, once rare in younger populations, is now on the rise among individuals under 50. Millennials have twice the risk of colorectal cancer compared to those born in 1950, according to a 2017 study. Factors like rising obesity rates, reduced physical activity, and changes in gut microbiota due to processed foods all contribute to this trend.

    Mounting evidence suggests that ultra-processed foods, high in omega-6-rich oils and low in omega-3s, are a significant driver of this risk. “We’re not saying omega-6 is inherently bad,” Yeatman said to CNN. “The problem lies in the imbalance. Our ancestors’ diets provided the right proportion of these fats, but modern convenience foods have upset this delicate equilibrium.”

    How to reduce cancer risk
    To reduce cancer risk and promote overall health, experts recommend increasing omega-3 intake while moderating omega-6 consumption. The American Heart Association suggests eating two servings of fatty fish, such as salmon or mackerel, per week. Plant-based sources of omega-3, like flaxseeds and walnuts, can also help restore balance. Limiting ultra-processed foods and choosing whole, minimally processed options are key steps toward achieving a healthier dietary pattern.​


    Also not a surprise to anyone...

    The seed oil rabbit hole reached our sweet Invisy, dear lord help us before it ends us all. The fact that people are catching on to processed food being bad, in 2024, from the seed oil trend is crazy lol.

    The supposed goal is low saturated fat with a decent omega 3-6 ratio (between 1:1 to 1:4). You can see the insane ratios for Corn, soy, sunflower. Olive oil isn't even within the ideal ratio but it's not nearly as bad.

    In general for Omega 3, EPA and DHA are the prizes. Fatty fish, or algae supplements are the way.

    Most of the stuff I saw during the lockdown dealt with heart issues. This new stuff about colon cancer is harder to deny as "fringe"

    I've been sticking with olive and grapeseed oil for cooking. Not a fan of the coconut taste.

    I also love me some restaurant food so I'm mostly in deep with seed oil

    I think this trend at its base is just another branch of the carnivore / paleo groups. If concerned about heart issues, be weary of the saturated fat issue.

    My house literally just has regular olive oil for cooking and extra virgin olive oil for things like making guac or a salad.

    I find no other need for any other type of oil. I don't deep fry anything at home. My mom always cooked with olive oil since I was a kid which isn't normal for a Desi immigrant parent. She heard it was much healthier than canola oil which Desi parents use all the time when they cook. She was told this way back and it stuck with her so I'm lucky in that sense. So now out of habit I don't really use any other cooking oil.

    Things I will continue to not worry about:

    Seed Oils. If they are taking you down, you should really consider to the amount of oil you are ingesting.

    I've been only using olive oil for cooking since I turned 18. It's almost impossible to avoid soybean oil in this day and age though. Mayo? Ranch? Tarter? Sweet Baby Ray's BBQ Sauce? I think I saw some on the ice cream label.

    Olive oil and avocado oil for me. I use avocado oil when I need something with a really high burn point.

    Exact same here.

    Although many Avocado oils are adulterated apparently.

    It's high in linoleic acid, but it's not clear even that linoleic acid increases inflammation - in some studies it decreases. They don't fully understand what is going on here. But it's more complex.

    I love using sesame oil especially for things like stir-fry. I take Omega 3 supplements though.

    Sesame oil is a must for stir frying it's also a great emulsifier for other liquid flavors for chilled Asian salads.

    fwiw

    Burmese/Chinese/Koreans/Viets/Indonesian/Malays/Taiwanese don't cook with sesame oil; instead it is primarily used as a finishing oil,
    adding a rich, nutty flavor to dishes by drizzling it on at the end of cooking rather than using it for high-heat sautéing

    Sesame oil has and omega 6 to 3 ratio of about 40 to 1

    Sorry the chart doesn’t have everything (I occasionally use Walnut oil, for example which isn’t there), others have mentioned avocado, sesame. If one is curious you can search the fat contents on Google fairly easily for whatever you’re interested in.

    Butter: 70% saturated, 25%, mono, and 5% polyunsaturated (pretty much the same as the listed butterfat)

    Beef fat: 50% saturated, 45% mono, 5% poly

    Unlike a plant, the omega ratios for the two can vary quite a bit depending on the diets of the cow. An example with just beef:

    Lets fry all of our ultra-processed foods and blame the oils.

    Just keep your oils off the carbs.

    Big Corn is the culprit to many US health issues.

    And environmental. Like growing crops to turn into fuel is pretty dumb.

    We don't grow them to turn them into fuel. We grew them and then needed something to do with them. Corn farming welfare.
