原花青素（PAS）已被证明具有潜在的健康益处。然而，没有关于他们饮食摄入量的数据。因此，分析了来自美国的普通食品和婴儿食品中的PAS。根据我们的数据和1994-1996年美国农业部个人食物摄入量持续调查（CSFII）的数据，美国人口（>2岁）的PAS平均每日摄入量估计为57.7 mg/人。单体、二聚体、三聚体和三聚体以上的聚合物分别占总PAS的7.1%、11.2%、7.8%和73.9%。美国人饮食中PAS的主要来源是苹果（32.0%），其次是巧克力（17.9%）和葡萄（17.8%）。2- 5岁年龄组（68.2 mg/人）和>60岁的男性（70.8 mg/人）每天消耗的PAS比其他组更多，因为他们消耗更多的水果。根据美国儿科学会的建议，4至6个月大和6至10个月大婴儿的PAS每日摄入量估计分别为1.3 mg和26.9 mg。这项研究支持的概念，PAS占一个主要部分的总黄酮摄入西方饮食。
Proanthocyanidins (PAS) have been shown to have potential health benefits. However, no data exist concerning their dietary intake. Therefore, PAS in common and infant foods from the U.S. were analyzed. On the bases of our data and those from the USDA's Continuing Survey of Food Intakes by Individuals (CSFII) of 1994-1996, the mean daily intake of PAS in the U.S. population (>2 y old) was estimated to be 57.7 mg/person. Monomers, dimers, trimers, and those above trimers; contribute 7.1, 11.2, 7.8, and 73.9% of total PAS, respectively. The major sources of PAS in the American diet are apples (32.0%), followed by chocolate (17.9%) and grapes (17.8%). The 2- to 5-y-old age group (68.2 mg/person) and men >60 y old (70.8 mg/person) consume more PAS daily than other groups because they consume more fruit. The daily intake of PAS for 4- to 6-mo-old and 6- to 10-mo-old infants was estimated to be 1.3 mg and 26.9 mg, respectively, based on the recommendations of the American Academy of Pediatrics. This study supports the concept that PAS account for a major fraction of the total flavonoids ingested in Western diets.
