[Scientific consensus on whole grains and health (2021)].

Grains are an important basic component of diet, as well as an important food source of nutrients such as B vitamins, minerals, and dietary fiber. According to the degree of processing, grains can be divided into refined grains and whole grains. The whole grains are processed by retaining the endosperm, germ, bran and nutrients. It can be either a complete grain or products after simple processes, such as grinding, crushing and tablet pressing. Regular consumption of whole grains can help maintain healthy weight and reduce the risk of cardiovascular disease, type 2 diabetes, and intestinal cancer. The public should be encouraged to gradually change the consumption habit of refined grains and increase the proportion of whole grains in the dietary structure.谷物是膳食的重要基础组成部分，也是B 族维生素、矿物质、膳食纤维等营养素的重要食物来源。根据加工程度不同，谷物可分为精制谷物和全谷物。全谷物的特点是保留了完整谷粒所具备的胚乳、胚芽和麸皮及营养成分。它既可以是完整的谷物籽粒，也可以是碾磨、粉碎、压片等简单处理后的产品。经常食用全谷物，不仅可以有助于维持健康体重，还可以降低心血管疾病、2型糖尿病、肠道癌症等疾病的患病风险。应鼓励公众逐步改变“精、细、白”的主食消费习惯，提高全谷物在膳食结构中的比例。.
