Individuals who consume food high in carbs and glycemic index are 4.5 times more likely to develop lung cancer, a new study shows.


According to a new study published in the Cancer Epidemiology, Biomarkers & Prevention, high GI food such as white bread, potatoes, and bagels, among others, could put one at risk of lung cancer.

A team of researchers from the University of Texas asked 1,900 individuals diagnosed with lung cancer and 2,400 healthy participants as the control group. The participants from both groups were asked about their diet and lifestyle, which were later compared for analysis.

The researchers have found that the individuals whose diets were high in carbs and GI have a 49 percent chance of developing lung cancer than those who consume less amount of high-GI food.

While the study shows the possible interaction between high GI diet and lung cancer, the same study does not establish causality. Still, smoking remains the leading factor in developing lung cancer.

In fact, no less than Dr. Xifeng Wu of the University of Texas told the Huffington Post that compared to smoking as a risk factor to lung cancer, the association of a high GI diet to lung cancer remains relatively small.

“The associations between glycemic index and lung cancer were still relatively small, particularly when we think of the impact of other risk factors such as smoking. It’s easy to lose some of the nuance of the study when conveying the overall message to the public,” Wu was quoted as saying by the Huffington Post.

According to the latest data from the Center for Disease Control and Prevention (CDC), lung cancer is the second most common cancer and the leading cause of death in the United States. The agency notes that the most important thing to remember is to avoid smoking and inhaling second-hand smoke.

Of the 210,828 Americans who were diagnosed with lung cancer in the U.S., more than half, or 111,395, are men; the remaining 99,433 are women. A total of 157,423 individuals have so far died of this condition, the CDC data shows.
