title: Tailoring Grain Storage Reserves for a Healthier Rice Diet and its Comparative Status with Other Cereals.
abstract: A global rise of diet-related noncommunicable diseases calls for a focus on diet-based nutritional intervention across the entire socioeconomic consumer spectrum. We review recent reports in the area of healthier rice aimed at developing rice grains with improved dietary fiber compositions (increased amounts of nonstarch polysaccharides and resistant starch), and less digestible starch (higher amylose and phospholipid complex in the endosperm) resulting in reduced glycemic impact upon grain consumption. We furthermore elaborate on the interconnections of elevated amounts of protein and a balanced composition of essential amino acids. The importance of a nutritious aleurone layer and its role in lipid storage and micronutrient composition is discussed briefly in the context of brown rice benefits. We identify gene targets for precision breeding that will facilitate the production of rice grains and rice-based products to mitigate the impact of nutrition-related preventable diseases.
