Beef is an excellent source of nutrients important for maternal health and fetal development. It is also true that the Mediterranean diet is beneficial for the health of both the mother and offspring; however, the relative value of fresh beef intake within Mediterranean diet patterns during pregnancy is unknown. The objective of this project was two-fold: (1) assess the relationship between beef intake and nutrient intake in a pregnant population; (2) assess the relationship between maternal beef consumption among varying degrees of Mediterranean diet adherence with maternal risk of anemia and infant health outcomes. This is a secondary analysis of an existing cohort of pregnant women ( = 1076) who participated in one of two completed clinical trials examining the effect of a docosahexaenoic acid supplementation on birth and offspring outcomes. Women were enrolled between 12 and 20 weeks of gestation and were followed throughout their pregnancies to collect maternal and infant characteristics, food frequency questionnaires [providing beef intake and Mediterranean diet (MedD) adherence], and supplement intake. Women with the highest fresh beef intake had the highest intake of many micronutrients that are commonly deficient among pregnant women. Fresh beef intake alone was not related to any maternal or infant outcomes. There was a reduced risk of anemia among women with medium to high MedD quality and higher fresh beef intake. Women in the medium MedD group had 31% lower odds of anemia, and women in the high MedD group had 38% lower odds of anemia with every one-ounce increase in fresh beef intake, suggesting that diet quality indices may be misrepresenting the role of fresh beef within a healthy diet. These findings show that beef intake increases micronutrient intake and may be protective against maternal anemia when consumed within a healthy Mediterranean diet pattern.
牛肉是营养丰富的食物，对产妇健康和胎儿发育都很重要。地中海饮食也有益于母婴健康；然而，在怀孕期间，地中海饮食模式中新鲜牛肉的摄入量相对价值尚不清楚。本项目的目的有两个：（1）评估孕妇群体中牛肉摄入量与营养摄入量之间的关系；（2）评估不同程度地中海饮食依从性下的产妇牛肉摄入量与产妇贫血风险和婴儿健康结果之间的关系。这是对现有孕妇队列（=1076）的二次分析，这些孕妇参加了两项已完成的临床试验之一，以研究二十二碳六烯酸补充对分娩和后代结局的影响。女性在妊娠 12 至 20 周时入组，并在整个孕期内进行随访，以收集产妇和婴儿特征、食物频率问卷（提供牛肉摄入量和地中海饮食[MedD]依从性）和补充剂摄入量。新鲜牛肉摄入量最高的女性摄入了许多在孕妇中普遍缺乏的微量营养素。单独的新鲜牛肉摄入量与任何产妇或婴儿结局均无关。中等到高度 MedD 质量和较高新鲜牛肉摄入量的女性贫血风险降低。中 MedD 组的女性贫血风险降低 31%，高 MedD 组的女性贫血风险降低 38%，每增加一盎司新鲜牛肉摄入量，这表明饮食质量指数可能无法准确反映新鲜牛肉在健康饮食中的作用。这些发现表明，牛肉摄入量增加了微量营养素的摄入量，并且当在健康的地中海饮食模式中食用时，可能有助于预防产妇贫血。
