Vitamin B-12 is of singular interest in any discussion of vegetarian diets because this vitamin is not found in plant foods as are other vitamins. Many of the papers in the literature give values of vitamin B-12 in food that are false because as much as 80% of the activity by this method is due to inactive analogues of vitamin B-12.
在任何关于素食饮食的讨论中，维生素B-12都有着独特的意义，因为这种维生素不像其他维生素那样存在于植物性食物中。文献中的许多论文给出的食物中维生素B-12的值都是错误的，因为用这种方法检测到的高达80%的活性是由维生素B-12的无活性类似物所致。
