Does White Rice Boost Diabetes Risk?
Study: White Rice Boosts Diabetes Risk
Health researchers said on Thursday they had found a troubling link between higher consumption of rice and Type-2 diabetes, a disease that in some countries is becoming an epidemic.
Further work is needed to probe the apparent association and diets that are notoriously high in sugar and fats should remain on the no-go list, they cautioned.
"What we've found is white rice is likely to increase the risk of Type-2 diabetes, especially at high consumption levels such as in Asian populations," Qi Sun of the Harvard School of Public Health told AFP.
"But at the same time people should pay close attention to the other things they eat.
"It's very important to address not just a single food but the whole pattern of consumption."
In the British Medical Journal, Sun's team said the link emerged from an analysis of four previously published studies, carried out in China, Japan, Australia, and the United States.
These studies followed 350,000 people over a timescale from four to 22 years. More than 13,000 people developed Type-2 diabetes.
In the studies carried out in China and Japan, those who ate the most rice were 55 percent likelier to develop the disease than those who ate the least. In the United States and Australia, where consumption of rice is far lower, the difference was 12 percent.
Participants in the two Asian countries ate three or four servings of rice a day on average, compared to just one or two servings a week in the Western countries.
White rice is the dominant form of rice eaten in the world. Machines produce its polished look by hulling and milling, leaving a grain that is predominantly starch.
Brown rice, by contrast, has more fiber, magnesium and vitamins, and a lower "glycemic index," a measurement of sugar content, than white rice. However, the glycemic index also takes in consideration the portion size. The glycemic index of a carbohydrate can be lowered by combining the carbohydrate with protein, some healthy fats, or raw vegetables.
Sun said the study did have limitations, including full details about what the volunteers ate in addition to rice.
"I don't think I can put forward a 100 percent confirmed case, given that this is a meta-analysis of four original studies," he said.
"But I see a consistency across these studies, and there is biological plausibility that supports the association between white rice consumption and diabetes."
He added: "More trial data are needed to corroborate or refute our observations."
Diabetes affects nearly 350 million adults worldwide, according to the Centers for Disease Control and Prevention.
One of the main risks to people, who are starting to show signs and symptoms of Type-2 diabetes, is the decrease in blood circulation. This usually shows first in the lower extremities with lack of blood flow to the toes. Left untreated, Type-2 diabetes begins a downward slide of high blood pressure, high lipids, and an increase in the dangerous visceral fat.
Diet is only one factor in Type-2 diabetes, a complex disease that involves high levels of blood sugar that cannot be processed by the hormone insulin. Obesity and lack of exercise are also cited as culprits.
The good news is that caught early, functional medicine healthcare providers have a variety of treatment protocols that can not only stop the progression of diabetes, but can reverse the harmful effects, and improve overall health.
