Rice is considered the most important grain with regards to human nutrition and caloric intake, providing more than one-fifth of the calories consumed worldwide by humans, as previously mentioned. Here Rei Kurohi, StraitsTimes.com, reflects on two new studies regarding the risk of eating white rice daily and diabetes:

 

“Cutting down on white rice may not in itself lower a person's risk of getting diabetes, two new studies have found.

The risk depends on what the rice is substituted with and the overall quality of a person's diet, said Professor Koh Woon Puay, director of the Centre for Clinician-Scientist Development at Duke-NUS Medical School, a co-author of the studies.

Both studies used data from the ongoing Singapore Chinese Health Study, which was started in 1993 by the National University of Singapore (NUS).

This comes after a series of previous studies that linked white rice to diabetes. In 2016, Singapore's Health Promotion Board cited studies by the Harvard School of Public Health in the United States which showed that each plate of white rice eaten daily on a regular basis raises the risk of diabetes by 11 per cent in the overall population.

In one study, researchers from NUS and Duke-NUS Medical School found no link between the quantity of white rice consumed and the risk of Type 2 diabetes when controlled for other variables like age, sex and body mass index (BMI), and various other food intakes.

Type 2 diabetes is related to weight management, and is a result of blocked or reduced insulin receptors. Over 90 per cent of diabetics suffer from Type 2 diabetes.

“Even over a relatively wide range of rice intakes, from half a bowl to several bowls a day, we didn't see much of an increase in the risk of diabetes,” said Professor Rob Martinus van Dam, domain leader of epidemiology at the Saw Swee Hock School of Public Health in NUS and one of the study's co-authors.

Prof van Dam said the study showed that a person who eats less rice is likely to eat more of something else to maintain the same calorie intake.

But people who ate different foods in place of rice were affected differently.

For example, a person may choose more noodle dishes, which are often cooked in sauces that are high in salt and oil, he said. Others may eat more meat to feel full.

These increase their risk of diabetes.

Substituting rice with whole grains, on the other hand, decreases the risk.

Another study, also involving Prof van Dam and Prof Koh, used established diet quality indices to determine the overall “quality” of a person's dietary pattern.

They then measured the link between diet quality and diabetes risk.

A list of 165 food items and beverages were identified, covering an estimated 90 per cent of what is commonly eaten by the population in Singapore.

It is the first such study to examine local food specifically.

The researchers said the study found that whole grains, fruits, vegetables, nuts and a moderate amount of dairy were associated with lower risks of cancer, diabetes, heart disease and stroke, in line with other established dietary studies from mostly Western countries.”
