Rice is a staple food for millions worldwide, but a new approach to enhancing its nutritional value is offering a potential solution to address both diabetes and hidden hunger. Researchers in India have developed a new, fortified variety of rice designed to improve public health and combat malnutrition.
While rice provides energy and contains essential macronutrients and micronutrients, its high starch content and low levels of protein, fiber, and key nutrients have long been a concern for health experts. This carbohydrate-rich composition can also lead to rapid spikes in blood sugar levels. To address these challenges, scientists at the Council of Scientific and Industrial Research – National Institute for Interdisciplinary Science and Technology (CSIR-NIIST) in Thiruvananthapuram have created what they call “designer rice.”
Unlike genetically modified crops, this innovative rice is produced using advanced food processing techniques, rather than genetic engineering. The process involves breaking down traditional rice into its core components – starch, protein, and fiber – and then reassembling them in a way that boosts the grain’s nutritional profile.
A key aspect of this innovation is the utilization of broken rice, often considered a low-value byproduct of the milling process. Scientists grind the broken rice into flour, then mix it with added protein and essential micronutrients like iron, folic acid, and vitamin B12. The mixture is then processed and reshaped into grains resembling ordinary rice.
According to researchers, the resulting “designer rice” offers several potential health benefits. It has a lower glycemic index – below 55 – meaning it releases glucose into the bloodstream more slowly, which could be particularly beneficial for individuals managing diabetes. The new variety also boasts a significantly higher protein content, exceeding 20 percent compared to the 6 to 8 percent found in regular rice, thereby increasing its nutritional value.
The concern surrounding traditional white rice stems from its high carbohydrate content, which can cause a rapid increase in blood sugar levels after meals. This is particularly relevant in India, which has one of the largest populations of people with diabetes globally. Simultaneously, millions of Indians suffer from hidden hunger, a condition where individuals consume enough calories but lack essential nutrients like protein, iron, and vitamins.
Because rice is so widely consumed, improving its nutritional value has the potential to significantly impact public health. The developers emphasize that the designer rice maintains the familiar taste, texture, and cooking properties of conventional rice, making it easier for consumers to adopt.
What is Designer Rice?
Researchers at CSIR-NIIST have developed a new type of rice with higher protein levels and a lower glycemic index than traditional rice.
Why is traditional rice a concern?
The enhanced rice is fortified with iron, folic acid, and vitamin B12, essential nutrients for preventing anemia and other nutritional deficiencies. This innovation offers a promising approach to addressing widespread nutritional gaps and improving public health outcomes.
What are the benefits of Designer Rice?
The newly developed rice provides several potential health benefits:
Lower Glycemic Index
The designer rice has a glycemic index of less than 55, meaning it releases glucose into the bloodstream slowly. This may help reduce blood sugar spikes, making it beneficial for people with diabetes.
Higher Protein Content
While regular rice contains about 6 to 8 percent protein, the new variety can contain more than 20 percent protein, significantly enhancing its nutritional value.
Micronutrient Enrichment
The rice is fortified with iron, folic acid, and vitamin B12, essential nutrients for preventing anemia and other nutrient deficiencies.
