以纽约罗切斯特食品为代表的常用食品，对其总生育酚和α-生育酚含量进行了化学分析。在所获得的结果的基础上，Avg.人均维生素T消费量。美国的E估计为14毫克。D，α-生育酚(13IU.)每天。维生素T最丰富的饮食来源。我们确信这些植物油是可靠的。谷类食品和鸡蛋的营养重要性排在第二位。蔬菜在维生素T的每日摄入量中占很小的比例。E，都是因为它们的浓度较低。因为在大多数情况下，存在的生育酚中有很大一部分是相对不活跃的非α-生育酚。同样，动物产品也是维生素T的贫乏来源。E，因为它们的浓度很低，而且变化很大。然而，几乎所有的生育酚都是α-生育酚。生育酚浓度。动物产品中的维生素T含量可能与维生素T水平成正比。E与它们来自的动物的饮食有关，相反，与加工的严重程度和它们所受的储存时间有关。谷类产品作为维生素T来源的价值。E当然取决于它们在消费前所经历的研磨过程的程度和严重程度。
Commonly used foods, typified by those available in Rochester, N. Y., were chemically analyzed for their total tocopherol and alpha-tocopherol content. On the basis of the results obtained, the avg. per capita consumption of vit. E in the United States was estimated as 14 mg. of d, alpha-tocopherol (13 I.U.) daily. The richest dietary sources of vit. E are certain of the vegetable oils. Cereal products and eggs are next in order of nutritional importance. Vegetables supply very little of the daily intake of vit. E, both because of their low concn. of total tocopherols and because in most instances a large portion of the tocopherols present are the relatively inactive, non-alpha-tocopherols. Animal products, similarly, are rather poor sources of vit. E because of their quite low and variable concns. of total tocopherol, practically all of which, however, is alpha-tocopherol. The tocopherol concn. in animal products is probably directly proportional to the level of vit. E in the diet of the animals from which they come and, inversely, to the severity of processing and length of storage to which they are subjected. The value of cereal products as a source of vit. E certainly depends upon the extent and severity of the milling process which they undergo prior to consumption.
