This work investigated the nutritional and mineral composition of three red seaweed species, Palmaria palmata, Porphyra umbilicalis and Chondrus crispus, and an in vitro assay was performed to determinate the effects of the intake of whole red seaweed on gut microbiota, short chain fatty acids production and metabolic pathways. The results obtained showed that 100 g of seaweeds contained essential minerals such as 28-107 % daily needs of Ca, 183-600 % daily needs of Fe and 18-54 % daily needs of Zn, whereas low content were found for Cu and I. Seaweed digestion fermentation showed beneficial effects of gut microbiota, as increases in beneficial species such as Akkermansia muciniphila, and in some seaweed, Bifidobacterium adoslescentis, Bacteroides ovatus or Lactobacillus ruminis. Metabolic pathways did only found little significant differences with respect to inulin fermentation. In view of the results, red seaweed showed prebiotic effects on human gut microbiota.
本研究调查了三种红藻（掌状红皮藻、紫菜和皱波角叉菜）的营养和矿物质成分，并进行了一项体外试验，以确定摄入完整红藻对肠道微生物群、短链脂肪酸产生和代谢途径的影响。所得结果表明，100克海藻含有钙（占每日需求量的28 - 107%）、铁（占每日需求量的183 - 600%）和锌（占每日需求量的18 - 54%）等必需矿物质，而铜和碘的含量较低。海藻消化发酵对肠道微生物群显示出有益作用，如嗜黏蛋白阿克曼氏菌等有益菌种数量增加，在某些海藻中，青春双歧杆菌、卵形拟杆菌或瘤胃乳杆菌数量也有所增加。代谢途径与菊粉发酵相比仅发现了微小的显著差异。鉴于这些结果，红藻对人类肠道微生物群显示出益生元效应。
