Palm oil is everywhere. It’s in your peanut butter, your shampoo, and even your favourite chocolate bar. But lately, this ubiquitous ingredient has been under fire, with headlines screaming, “Palm Oil Cause Cancer!” and “Is Your Cooking Oil Killing You?” It’s enough to make you want to toss out every product in your pantry. But before you do, let’s take a deep breath and ask the real question: Does palm oil really cause cancer?
To get to the bottom of this, I spoke with Dr. Emily Carter, a board-certified oncologist with over 15 years of experience in cancer research. Her insights might just change the way you think about palm oil—and maybe even ease your mind a little.
What Is Palm Oil, Anyway?
Palm oil is a type of vegetable oil derived from the fruit of oil palm trees. It’s cheap to produce, has a long shelf life, and is semi-solid at room temperature, making it a favourite for food manufacturers. It’s also used in cosmetics, cleaning products, and even biofuels.
But here’s the kicker: palm oil is everywhere. According to the World Wildlife Fund (WWF), it’s in nearly 50% of the packaged products in your supermarket. That’s a lot of palm oil.
The Cancer Controversy: What’s the Deal?
The concern about palm oil and cancer stems from a few key factors:
- Processing Methods: When palm oil is refined at high temperatures, it can form harmful compounds called glycidyl fatty acid esters (GEs). These compounds break down into glycidol during digestion, which has been classified as a probable human carcinogen by the International Agency for Research on Cancer (IARC).
- Saturated Fats: Palm oil is high in saturated fats, which have been linked to heart disease and, in some studies, certain types of cancer.
- Environmental Concerns: While not directly related to cancer, the environmental impact of palm oil production—deforestation, habitat destruction, and climate change—has made it a controversial ingredient.
But here’s where things get tricky. Just because something can cause cancer in a lab doesn’t mean it will cause cancer in real life. As Dr. Carter explains, “The dose makes the poison. We need to look at how much of these compounds people are actually consuming and whether that amount is enough to pose a real risk.”
What Does the Science Say?
Let’s break it down:
- Animal Studies: Some studies on rodents have shown that high doses of glycidol can cause tumors. But humans aren’t lab rats, and the amounts used in these studies are far higher than what you’d typically consume.
- Human Studies: The evidence in humans is less clear. While some studies have suggested a link between palm oil consumption and certain cancers, others have found no significant association. According to Dr. Carter, “The data is inconclusive. We don’t have enough evidence to say definitively that palm oil causes cancer in humans.”
- The Bigger Picture: Cancer is a complex disease influenced by genetics, lifestyle, and environmental factors. Blaming a single ingredient oversimplifies the issue. “It’s not just about palm oil,” says Dr. Carter. “It’s about your overall diet and lifestyle. Eating a balanced diet, exercising, and avoiding smoking are far more important than worrying about palm oil.”
Should You Avoid Palm Oil?
Here’s the thing: completely avoiding palm oil is nearly impossible unless you’re willing to give up most processed foods and personal care products. And even if you could, Dr. Carter cautions against overreacting.
“The key is moderation,” she says. “If you’re eating a diet rich in whole foods—fruits, vegetables, whole grains, and lean proteins—you’re probably not consuming enough palm oil to worry about. But if your diet is heavy on processed foods, palm oil might be the least of your concerns.”
She also recommends looking for sustainably sourced palm oil. “The Roundtable on Sustainable Palm Oil (RSPO) certifies products that meet certain environmental and ethical standards. Choosing these products can help reduce the environmental impact of palm oil production.”

Living in Fear vs. Living Well: A Doctor’s Perspective
Let’s be real: reading about cancer is scary. It’s easy to feel overwhelmed by all the conflicting information out there. But here’s a little perspective: life is full of risks. You could spend your days worrying about every little thing—or you could focus on the big picture.
As Dr. Emily Carter puts it, “I’ve seen patients who’ve done everything ‘right’ and still get cancer. I’ve also seen patients who’ve lived what you might call ‘unhealthy’ lives and never get sick. Cancer doesn’t play fair. But that doesn’t mean we should live in fear.”
So, instead of stressing over palm oil, why not take a step back and look at the bigger picture? Eat your veggies, go for a walk, and maybe swap out that bag of chips for an apple. And if you’re really worried about palm oil, check the label and opt for products with sustainable sourcing.
Palm Oil and Cancer: What You Really Need to Know
Does palm oil cause cancer? The answer isn’t black and white. While there are some legitimate concerns about its processing methods and potential health risks, the evidence isn’t strong enough to say it’s a direct cause of cancer in humans.
As Dr. Carter wisely reminds us, “Cancer is complicated. It’s not about one ingredient or one lifestyle choice. It’s about the cumulative effect of many factors over time. So, instead of fixating on palm oil, focus on living a balanced, healthy life.” And if you’re still worried? Well, there’s always dark chocolate. Just make sure it’s not the kind with palm oil.
