摘要
从一万年前生长在Crescent 地区的野生草类首次被驯化,到了解到它们全面的潜在营养价值,谷类谷物对现代人类进展而言仍然是必不可少的。世界上十二种最主要的作物中,有五种谷类 — 大米、小麦、玉米、大麦、高粱,仅此五类就占世界人口消耗热卡的一半以上。科学机构已经开始了解到谷类食品在热量能源之外的重要作用。包含全谷类食品的平衡膳食的重要性不能被过分强调。全谷类食品是食物碳水化合物、微量营养素和植物固醇的来源。一个例子是谷物糊粉层,在许多植物甾醇方面尤其丰富,并有潜在的抗氧化性质。另一个例子是麸皮中的可溶和不可溶的细胞壁成分,它是食物纤维的重要来源。在文献中提供了证实高纤维和全谷物食品在保持身体健康和预防的严重疾病的科学证据。膳食因素被认为可以影响人的体重和人体的防病的总体状况。这个会议将会总结复合糖的关系,全谷类产品和防止某些疾病包括二型糖尿病和冠心病等疾病。
From the domestication of wild grasses in the Fertile Crescent 10,000 years ago, to the understanding of their fullpotential nutritional value, cereal crops continue to be essential in the advancement of human cultures. Of the twelve mostimportant crops in the world, five are cereals (rice, wheat, corn, barley and sorghum) which alone account for more than half thecalories consumed by the world's human populations. The scientific community has begun to understand the important role ofcereal foods beyond a source of calories. The importance of a balanced diet, which includes whole cereal grain foods, can't be overemphasized. Whole grain foods are a source of dietary carbohydrates, micronutrients and phytochemicals. An example would bethe aleurone layer of cereals, which is especially rich in a number of phytosterols, with potent antioxidant properties. Anotherexample is the soluble and insoluble cell wall components in the bran which is an important source of dietary fiber. Supportingscientific evidence of the beneficial effect of high-fiber and whole grain foods in maintaining good health and preventing seriousillness is available in the literature. Dietary factors are thought to affect body weight and the overall state of the body inpreventing illness. The relationships of complex carbohydrates, whole grain products and the prevention of some diseases,including type-2 diabetes mellitus and coronary heart disease are summarized.
