Home cooking programs are an increasingly popular approach to nutrition education and have the potential to promote diet quality among pediatric cancer survivors. A cornerstone of many programs is the use of fresh fruits and vegetables, which may support increased intake of many food components, including carotenoids, to improve survivor health. However, most dietary carotenoids in the United States currently come from processed vegetables, and it is unclear if the emphasis on fresh fruits and vegetables common in cooking education programs is associated with the total carotenoid content of meals. The objective of this analysis is to examine the relationship between fresh produce usage, practices commonly taught in healthy home cooking classes, and the carotenoid content of prepared meals among 40 parents with school-aged children. This is a secondary analysis of an observational study examining the quality of home cooking practices using an evidence-based index of behaviors, the Healthy Cooking Index (HCI). Nutrition-optimizing cooking practices, as quantified by the HCI, were not associated with the carotenoid content of meals (r = -0.24, = 0.13). Further, total fruit and vegetable content of meals was not associated with total carotenoids (r = 0.14; = 0.38), indicating heterogeneity in the carotenoid profiles of foods used by this population. High-carotenoid meals tended to use more canned and/or frozen tomato and vegetable products, and carotenoid content was associated with meals with sugar (r = 0.32; = 0.04), and servings of refined grains (r = 0.49; < 0.01). Our findings indicate an opportunity to educate pediatric cancer survivors and families on the incorporation of high-carotenoid food products while reducing refined grain and sweetener intake through a tailored home cooking intervention.
家庭烹饪课程是一种越来越受欢迎的营养教育方法,有可能提高儿科癌症幸存者的饮食质量。许多项目的基石是使用新鲜水果和蔬菜,这可能支持增加许多食物成分的摄入量,包括类胡萝卜素,以改善幸存者的健康。然而,目前美国大多数膳食类胡萝卜素来自加工蔬菜,尚不清楚烹饪教育计划中常见的新鲜水果和蔬菜的强调是否与膳食的总类胡萝卜素含量有关。本分析的目的是研究新鲜农产品的使用、健康家庭烹饪课程中常见的做法与 40 名学龄儿童家长准备的膳食类胡萝卜素含量之间的关系。这是一项观察性研究的二次分析,该研究使用基于证据的行为指数,即健康烹饪指数 (HCI),来检查家庭烹饪实践的质量。营养优化烹饪实践,如 HCI 所量化的,与膳食类胡萝卜素含量无关(r = -0.24, = 0.13)。此外,膳食的总水果和蔬菜含量与总类胡萝卜素无关(r = 0.14; = 0.38),表明该人群使用的食物类胡萝卜素谱存在异质性。高类胡萝卜素膳食往往更多地使用罐装和/或冷冻番茄和蔬菜产品,类胡萝卜素含量与含糖的膳食(r = 0.32; = 0.04)和精制谷物的份量(r = 0.49; < 0.01)有关。我们的研究结果表明,有机会通过量身定制的家庭烹饪干预,在教育儿科癌症幸存者及其家庭时强调使用高类胡萝卜素食品,同时减少精制谷物和甜味剂的摄入。
