There’s a new warning for hardcore human carnivores: Red meat may increase your chances of kidney cancer, while vegetables might work as a protective agent.
The researchers at the University of Florida also discovered that people who ate large amounts of white bread and white potatoes were at greater risk than their peers who ate those foods less frequently.
"Foods that have a high glycemic index are known to affect insulin resistance and also insulin-like growth factors," Suzanne Dolwick Grieb told Reuters Health in an interview. "Those two things have been implicated in other cancers.” They reported their findings in the latest edition of the Journal of the American Dietetic Association.
Grieb said that cancer is on the rise in the United States and that the best risk factors for the disease are obesity and cigarette smoking. So far, “studies on diet and renal cell carcinoma – which accounts for 85 percent of kidney cancers – have had ‘inconclusive’ results,” Reuters reports.
Grieb’s research group studied which foods might influence the risk of renal cell carcinoma by comparing 335 people with renal cell carcinoma with 337 healthy people.
“While eating spinach and other greens, as well as tomatoes, reduced cancer risk in all study participants, especially men, white potatoes — including both fried and non-fried — increased it, the researchers found, with the strongest effects seen in women.”
