Does White Rice Increase Your Risk For Diabetes?
White rice might be pleasing to the palate, but it could also significantly increases the risk of type 2 diabetes.A Harvard School of Public Health study has found evidence of the association between eating white rice and the risk of type 2 diabetes.
The study seeks to determine whether this risk is dependent on the amount of rice consumed and if the association is stronger for the Asian population, who tend to eat more white rice than the Western world.
The authors analysed the results of four studies: Two in Asian (China and Japan) and two in Western countries (US and Australia). All participants were diabetes free at study baseline, reports the British Medical Journal.
White rice is the predominant type of rice eaten worldwide and has high Glycemic Index (GI) values. High GI diets are tied with a greater risk of type 2 diabetes, according to a Harvard statement.
GI indicates how fast and how high a particular food can raise our blood glucose (blood sugar) level. A food with a low GI will typically prompt a moderate rise in blood glucose while a food with a high GI may cause our blood glucose level to increase above the optimal level.
The average amount of rice eaten varies widely between Western and Asian countries, with the Chinese population eating an average of four portions a day and those in the Western world eating less than five portions a week.
The results also show that the more white rice eaten, the higher the risk of type 2 diabetes: the authors estimate that the risk of type 2 diabetes is increased by 10 percent with each increased serving of white rice (assuming 158 grams per serving).
White rice has a lower content of nutrients than brown rice, including fibre, magnesium and vitamins, some of which are associated with a lower risk of type 2 diabetes. The authors report, therefore, that a high consumption of white rice may lead to increased risk because of the low intake of these nutrients.
