A nutritional analysis was conducted on the dietary intake of a group of 6 vegan children aged 7 to 14 who had been living on a vegan diet including brown rice for from 4 to 10 years, and on that of an age-matched control group. In addition, their serum vitamin B12 levels and other data (red blood cell count, hematocrit, hemoglobin, etc.) were determined in the laboratory. In vegans' diets, 2-4 g of nori (dried laver), which contained B12, were consumed daily. Not a single case of symptoms due to B12 deficiency was found. There were no statistically significant differences between the two groups with respect to any of the examination data, including B12 levels (p < 0.05). Therefore, consumption of nori may keep vegans from suffering B12 deficiency.
对一组6名7至14岁的纯素食儿童进行了饮食摄入的营养分析，这些儿童食用包括糙米在内的纯素饮食已有4至10年，并与年龄匹配的对照组进行了比较。此外，在实验室中测定了他们的血清维生素B12水平和其他数据（红细胞计数、血细胞比容、血红蛋白等）。在纯素食者的饮食中，每天食用2 - 4克含有B12的紫菜（干海苔）。未发现一例因B12缺乏引起的症状。两组在包括B12水平在内的任何检查数据方面均无统计学显著差异（p < 0.05）。因此，食用紫菜可能使纯素食者避免B12缺乏。
