A new study from the Harvard School of Public Health shows that people who eat lots of white rice may significantly raise their risk of developing type 2 diabetes. The study looked at rice consumption in more than 352,000 people in China, Japan, U.S. and Australia. CBS reports: 

People who ate the most white rice were more than 1.5 times likely to have diabetes than people who ate the least amount of rice. What’s more, for every 5.5 ounce-serving of white rice – a large bowl – a person ate each day, the risk rose 10 percent.

“This applies for both Asian and Western cultures, although due to findings suggesting that the more rice eaten the higher the risk, it is thought that Asian countries are at a higher risk,” the researchers wrote in the study, published in the March 15 issue of the British Medical Journal.

What should people do? Researchers say dial back on the rice consumption: “Eating white rice one to two times per week is fine.”
