Red Meat Linked to Increased Diabetes Risk
Large study finds higher consumption increases risk, but experts are at odds with findings

MONDAY, June 17 (HealthDay News) -- People who eat a lot of red meat increase their risk of developing type 2 diabetes, while those who cut down on red meat cut their risk.
Those are the findings of a large new study out of Singapore involving 149,000 U.S. men and women.
The researchers found that increasing the consumption of red meat can increase the risk of developing type 2 diabetes by 48 percent.
"There is no need to have more red meat on your plate; it increases the risk of diabetes," said lead researcher An Pan, an assistant professor at the Saw Swee Hock School of Public Health at the National University of Singapore.
"It is better to reduce your red meat consumption by replacing it with other healthy food choices, like beans, legumes, soy products, nuts, fish, poultry and whole grains," he added.
The report was published in the June 17 online edition of the journal JAMA Internal Medicine.
For the study, Pan's team collected data on three Harvard group studies: the Health Professionals Follow-up Study, the Nurses' Health Study and the Nurses' Health Study II. All the participants answered questions about their diet every four years, resulting in more than 1.9 million person-years of follow-up.
There were more than 7,500 cases of type 2 diabetes, the researches found.
Comparing diet with the cases of diabetes, Pan's group found that people who increased their consumption of red meat by 0.5 servings per day during a four-year period were 48 percent more likely to develop type 2 diabetes, compared with people who ate less red meat.
Moreover, people who cut their red meat consumption were 14 percent less likely to develop type 2 diabetes, they found.
Outside experts, however, argued about the findings.
"Epidemiological studies made by questionnaires are not accurate, and they never prove causation, no matter how big and how good the statistics are," said Dr. Joel Zonszein, director of the Clinical Diabetes Center at Montefiore Medical Center in New York City.
