Researchers achieve significant progress in addressing global health concern, enhancing vitamin B1 content in rice without compromising yield.

In a groundbreaking development, a team of researchers has successfully developed a biofortified rice line aimed at combating vitamin B1 deficiency, a prevalent health issue affecting millions worldwide. Led by scientists from the University of Geneva (UNIGE), in collaboration with teams at ETH Zurich and Taiwan's National Chung Hsing University (NCHU), the initiative marks a crucial advancement in the fight against malnutrition associated with rice-based diets.

Vitamin B1, an essential micronutrient critical for nervous and cardiovascular health, is often lacking in rice, particularly due to processing methods such as polishing, which strip away vital nutrients. This deficiency contributes to a myriad of diseases, posing a significant public health concern in regions where rice is a dietary staple.

The research team, led by Professor Teresa Fitzpatrick of UNIGE's Department of Plant Sciences, targeted the enhancement of vitamin B1 content specifically in the endosperm of rice grains, the primary edible portion. Previous efforts had focused on increasing vitamin B1 levels in leaves and bran, but had not addressed the deficiency in the final rice product.

Through meticulous research and innovative techniques, the scientists succeeded in significantly boosting the vitamin B1 content in rice endosperm while maintaining agronomic yield. This breakthrough holds immense promise in addressing chronic deficiencies and improving overall nutritional outcomes, particularly in regions heavily reliant on rice consumption.
