Seeds of amaranth (Amaranthus spp.), buckwheat (Fagopyrum esculentum and F. tataricum) and quinoa (Chenopodium quinoa) become popular foods due to their attractive health effects. Cell wall polysaccharides are the major components of dietary fiber and significantly contribute to diverse health effects of the grains. This review summarizes the chemical and physical structure, biological functions and food uses of the cell wall polysaccharides and fractions as fiber components from the 3 pseudocereals. The properties and uses of the polysaccharides and fractions are compared with those of fiber polysaccharides from common sources such as fruits and vegetables. Overall, the fiber polysaccharide composition of the pseudocereals is more similar to that of fruits and vegetables than to that of cereals. The fiber polysaccharides showed a range of biological functions such as antioxidation, anticancer and immunomodulation. The fiber polysaccharides of amaranth, buckwheat and quinoa have potential to be used in formulations of functional foods.

of菜（Amaranthus spp。），荞麦（Fagopyrum esculentum和F. tataricum）和藜麦（Chenopodium quinoa）的种子）由于具有诱人的健康功效而成为流行食品。细胞壁多糖是膳食纤维的主要成分，并且对谷物的多种健康影响做出了重要贡献。这篇综述总结了细胞壁多糖和作为3种假谷物纤维成分的级分的化学和物理结构，生物学功能以及食品用途。将多糖和馏分的性质和用途与来自常见来源（例如水果和蔬菜）的纤维多糖的性质和用途进行了比较。总体而言，假谷物的纤维多糖成分与水果和蔬菜的纤维多糖成分相比，与谷物的更为相似。纤维多糖显示出一系列生物学功能，例如抗氧化，抗癌和免疫调节。of菜的纤维多糖，
