Overconsumption of refined carbohydrates like white rice can raise triglyceride and blood glucose levels, which are major risk factors for obesity, type 2 diabetes (T2D), and cardiovascular diseases. This is expected to be a huge health problem in countries where white rice is their major staple food mostly in south Asian countries such as Bangladesh, India, Pakistan, and Thailand, east Asian countries such as China, Japan, and Taiwan, and west African countries such as Nigeria and Ghana. There is a high intake of white rice in these countries, and the prevalence rate of T2D is high in these countries. White rice, both long grain and short grain, is really a kind of polished/refined rice, during the refining process, the bran and germ of the whole rice grain are separated, leaving only the carbohydrate-rich endosperm of the rice grain. This procedure deprives white rice of vital vitamins, minerals, and dietary fiber, brown rice which is an unrefined rice is rich in vitamins, minerals, and dietary fiber. White rice is a high glycemic food because of its high starch content and its ability to release glucose rapidly.
Lots of individuals from Asia and west Africa consume about four servings of white rice daily, but individuals from Europe and North America consumes <5 servings a week. The more ratios of white rice an individual consumes per day, the more the risk of developing T2D which is associated with lifestyle behavior, overweight, and obesity, there is a 10% increase in the risk of developing T2D for each increase in the ratio of white rice consumed per day. Eating more than three cups of white rice per day significantly increased the risk of T2D when compared with eating lesser quantity, this was the outcome of the multinational, multiethnic Prospective Urban Rural Epidemiology research. Individuals residing in south Asian nations are the most consumers of white rice and consequently have the highest chances of developing T2D. People who ate more than three cups of white rice per day which is >450 g per day had a 20% greater risk of developing T2D when correlated with people who ate <1 cup per day which is equivalent to 150 g of cooked white rice. South Asians who ate an average of 630 g of white rice daily had 61% higher chances of developing T2D compared to those who ate <150 g per day. Higher consumption of white rice, ≥5 servings per week as against <1 per month, was linked with a greater risk of T2D in US adult men, whereas higher consumption of brown rice, ≥2 servings per week as against <1 per month, was associated with a lesser risk of T2D. Replacing 50 g/day of raw white rice, which is equal to one-third serving per day, with the same quantity of brown rice was associated with a 16% decreased in the risk of T2D.
India has a large number of people with T2D, and India is the second after China in the risen incidence of T2D, and epidemiological data show that higher consumption of white rice contributes immensely to India's increased prevalence of T2D. However, replacing white rice with brown rice in a typical Indian daily diet could lessen this disease burden to a significant level. In India, nearly 70%–75% of the food intake comprises carbohydrates in the form of refined white rice, if this could be reduced to 45%–50% and the protein consumption can be upgraded to 20% by adding vegetables and some fruits, the daily diet will be healthier and considerably decreases the occurrence of T2D in India. High consumption of white rice substantially escalates the risks of T2D in Japanese and Chinese people., Substituting brown rice for white rice was active in reducing blood glucose levels among Nigerian adults.
In animal and human experiments, a high consumption of carbohydrates with a high glycemic index, which is a comparative measure of the incremental glucose response per gram of carbohydrate, increases insulin resistance than the consumption of low-glycemic-index carbohydrates. Replacing high-glycemic-index carbohydrates such as white rice with low-glycemic-index carbohydrates such as refined cereal products in patients with T2D improves glycemic control and decreases hypoglycemic episodes among diabetics treated with insulin. The consumption of unrefined whole grain is linked to a reduced risk of T2D, at least two servings of whole grain daily should be used to replace white rice to minimize the risk of T2D.
Brown rice has more fiber and antioxidants, as well as more essential vitamins and minerals than white rice, while white rice is rich in calories and carbohydrates. Substituting brown rice for white rice showed a possible advantage on glycated hemoglobin in individuals with metabolic syndrome and increased body mass index, it also reduced inflammation.w12]
In conclusion, there is a need for extensive community health education and promotion on the benefits of consuming brown rice in south Asian and west African countries, mostly among inhabitants in the rural areas. White rice has a high glycemic index, implying that it can trigger spikes in blood glucose levels, and there is a strong connection between the intake of high glycemic index foods with increased risk of T2D. Excess white rice consumption can lead to postprandial glucose rises, these rises, in turn, causes hyperinsulinemia, which is a homeostatic mechanism to maintain a normal concentration of glucose in the blood, however, with time the β-cells becomes weakened, resulting in β-cell malfunction and failure, subsequently leading to T2D.
