Porphyra sp. (nori) is widely cultivated as an important marine crop. Dried nori contains numerous nutrients, including vitamin B, which is the only vitamin absent from plant-derived food sources. Vegetarian diets are low in iron and vitamin B; depletion of both causes severe anemia. Nori also contains large amounts of iron compared with other plant-derived foods and eicosapentaenoic acid, which is an important fatty acid found in fish oils. In nori, there are also many bioactive compounds that exhibit various pharmacological activities, such as immunomodulation, anticancer, antihyperlipidemic, and antioxidative activities, indicating that consumption of nori is beneficial to human health. However, Porphyra sp. contains toxic metals (arsenic and cadmiun) and/or amphipod allergens, the levels of which vary significantly among nori products. Further evidence from human studies of such beneficial or adverse effects of nori consumption is required.
条斑紫菜（nori）作为一种重要的海洋作物被广泛种植。干紫菜含有多种营养物质，包括维生素 B，它是植物性食物来源中唯一缺乏的维生素。素食中缺铁和维生素 B；两者的缺乏都会导致严重的贫血。与其他植物性食物相比，紫菜还含有大量的铁和二十碳五烯酸，这是一种在鱼油中发现的重要脂肪酸。紫菜中还有许多具有各种药理活性的生物活性化合物，如免疫调节、抗癌、抗高血脂和抗氧化活性，表明食用紫菜有益于人类健康。然而，条斑紫菜含有有毒金属（砷和镉）和/或十足目甲壳类动物过敏原，其含量在不同的紫菜产品中差异很大。需要进一步的人类研究来证实紫菜消费的这种有益或有害影响。
