HYDERABAD: Data confirms an association between excess white rice intake with incident (new onset) type 2 diabetes, thanks to Prospective, Urban Rural Epidemiological Study (PURE study) published online in the American Journal Diabetes Care. Higher intake of white rice, (450 gms per day compared to &150 gms per day) was associated with an increased risk of diabetes. However, the highest risk was seen in South Asia where the rice intake was the highest, followed by other regions of the world, which included South East Asia, Middle East, South America, North America, Europe and Africa and China. 

How bad is it?
The association of white rice with incident diabetes was strongly correlated to the amount of white rice consumed. In South Asia, where the consumption of rice was 630g/day, the highest risk was seen, followed by South East Asia where the mean consumption was 239 g/day. 

Commenting on the results, Dr. Bhavadharini Balaji, first author of the paper, said that, “This is the largest study on white rice intake and incident diabetes ever done. It is also one of the first to be done across different countries and confirms that white rice intake is one of the contributors to the diabetes epidemic in South Asia”.

Dr.V.Mohan, second author of the paper, who conceived the study, added, “Excess white rice consumption was also associated with new onset (incident) diabetes in South India, particularly in Chennai. However, this study adds to the evidence because it was conducted on a much larger sample size, (n=132,2371 participants) across 21 countries and with a longer period of follow up. What comes out clear in the study is that, it is the amount of white rice consumed which is important. Clearly in India, the consumption of carbohydrate is too high in Southern and Eastern and North Eastern parts of the country it is mainly rice consumption which predominates, while in the North and West of India, wheat consumption is more. 

Earlier studies from our group have shown that refined carbohydrates like white rice have a very high glycemic index which contributes to a high glycemic load in the diet. This is correlated not only with increased risk of diabetes, but also of metabolic syndrome including high serum triglyceride levels and low HDL cholesterol concentrations. These characteristics of what is called as the ‘Asian Indian phenotype’ or the ‘South Asian phenotype’ could be largely contributed at least partly by excess rice intake.

What is the solution?
The solution for this is to reduce the amount of rice consumed or to change to healthier varieties of rice like brown rice. Also, by including legumes and pulses like Bengal gram, green gram, black gram, rajma etc, the protein and fiber content in the diet can be increased and the glycemic load can be reduced. This would help in making the diet healthier. In India, almost 70 – 75% of the diet consumed consists of carbohydrates in the form of polished white rice or refined wheat. 

If this can be brought down to 45-50 % and the protein intake can be increased up to about 20% by including vegetable protein and if healthy fats like mono unsaturated fats are increased along with plenty of green leafy vegetables and some fruits, this would make the Indian diet much healthier and reduce the incidence of type 2 diabetes and other non-communicable diseases in India”.

    It's not because of the white rice.... It's because of the mordern rice mills ... Polishing the rice tat peels off all the fibre content leaving only dense carbohydrates. This is a scam targetting the people to get this disorder
