A study reveals that an added sugar found in many foods can accelerate tumor growth

Sugar is everywhere—often in places we least expect it. While it’s common knowledge that excessive sugar consumption isn’t ideal for health, a new study has revealed something even more alarming: a widely used added sugar could fuel tumor growth in a surprising way.

The research focuses on fructose, a simple sugar naturally found in fruits. On the surface, it seems harmless—after all, fruits are considered healthy. But the concern isn’t about the fructose in whole foods; rather, it’s the added fructose, particularly in the form of high-fructose corn syrup, that has scientists raising red flags. Over the past century, fructose consumption has skyrocketed, particularly in processed foods and sugary drinks. In the U.S., intake levels have increased 15-fold, leading researchers to explore its deeper effects on the body.

A Surprising Link to Tumor Growth

Scientists at Washington University (WashU) in the U.S. recently investigated how fructose interacts with cancer cells. The results were striking: tumors grew at more than twice their usual rate in subjects consuming high amounts of fructose.

What’s unusual about this finding is that fructose doesn’t directly feed tumor cells. In a controlled lab setting, when researchers exposed isolated cancer cells to fructose, nothing happened. This contradicts the common assumption that tumors simply absorb nutrients straight from the bloodstream.

Dr. Gary Patti, a chemistry and medicine professor at WashU, explains: “People tend to think that when they eat something, tumors absorb it directly. But the human body is more complex. What you consume is often processed first by healthy tissues before tumors can use it.”

How the Liver Plays a Key Role ?

The missing link? The liver. When fructose enters the body, it is metabolized by the liver, which then releases compounds that indirectly fuel tumors. According to the study, liver cells exposed to fructose produce lysophosphatidylcholines (LPCs)—a type of lipid that circulates in the bloodstream. These lipids, in turn, are eagerly absorbed by cancer cells.

Why does this matter? Tumor cells need large amounts of lipids to build new membranes as they grow and divide. While they can synthesize these lipids themselves, it’s far easier to take advantage of free-floating LPCs in their environment. Essentially, fructose doesn’t feed cancer cells directly—but it primes the body to create the nutrients they need.

Could This Lead to New Cancer Treatments?

The implications of this study go beyond diet recommendations. Dr. Patti and his team found that various cancer types followed the same metabolic pathway, raising the question: could targeting the liver’s fructose metabolism slow tumor growth?

If scientists can develop therapies that block this process, they might be able to cut off an important nutrient source for tumors. This could complement existing cancer treatments, offering a new avenue for research in oncology and metabolic medicine.

What This Means for Your Diet ?

While more research is needed, one clear takeaway from this study is the potential risk of high fructose intake, particularly from processed foods and sweetened beverages. Dr. Patti advises that individuals with cancer—or those looking to minimize risk—should be cautious with added fructose.

“If you’re dealing with cancer, reducing fructose intake—especially in processed forms—could be a wise decision,” he notes. But as he acknowledges, avoiding fructose entirely is easier said than done, given its widespread use in the modern food industry.

For now, while fresh fruits remain a healthy part of a balanced diet, cutting back on high-fructose corn syrup and ultra-processed foods may be a smart step toward reducing unnecessary cancer risks. With ongoing research, we may soon understand even more about how our diet influences cancer development—and how we can better protect our health.
