Abstract：
The Nutritious Eating with Soul study was a 24-month, randomized behavioral nutrition intervention among African American adults. This present study, which is a secondary analysis of the NEW Soul study, examined changes in dietary acceptability, restraint, disinhibition, and hunger. Participants (n = 159; 79% female, 74% with ≥ college degree, mean age 48.4 y) were randomized to either a soul food vegan (n = 77) or soul food omnivorous (n = 82) diet and participated in a two-year behavioral nutrition intervention. Questionnaires assessing dietary acceptability (Food Acceptability Questionnaire; FAQ) and dietary restraint, disinhibition, and hunger (Three-Factor Eating Questionnaire; TFEQ) were completed at baseline, 3, 6, 12, and 24 months. Mixed models were specified with main effects (group and time) and interaction effects (group by time) to estimate mean differences in FAQ and TFEQ scores using intent-to-treat analysis. After adjusting for employment, education, food security status, sex, and age, there were no differences in any of the FAQ items, total FAQ score, dietary restraint, disinhibition, and hunger at any timepoint except for one item of the FAQ at 12 months. Participants in the vegan group reported a greater increase in satisfaction after eating a meal than the omnivorous group (mean difference 0.80 ± 0.32, 95% CI 0.18, 1.42; P = 0.01). This is one of the first studies to examine differences in dietary acceptability, hunger, and other eating factors among African American adults randomized to either a vegan or omnivorous soul food diet. The findings highlight that plant-based eating styles are equally acceptable to omnivorous eating patterns and have similar changes in hunger, restraint, and disinhibition. These results suggest that plant-based eating styles can be an acceptable dietary pattern to recommend for cardiovascular disease prevention and may result in greater post-meal satisfaction.
摘要：
营养饮食与灵魂的研究是一个24个月，非洲裔美国成年人的随机行为营养干预。本研究,这是对新灵魂研究的二次分析，检查了饮食可接受性的变化，克制,去抑制,和饥饿。参与者(n=159；79%为女性，74％具有≥大学学历，平均年龄48.4岁）被随机分配到灵魂食品素食（n=77）或灵魂食品杂食性饮食（n=82），并参加了为期两年的行为营养干预。评估饮食可接受性的问卷（食物可接受性问卷；FAQ）和饮食限制，去抑制,和饥饿（三因素饮食问卷；TFEQ）在基线时完成，3、6、12和24个月。指定了具有主要效应（组和时间）和相互作用效应（按时间分组）的混合模型，以使用意向治疗分析来估计FAQ和TFEQ评分的平均差异。调整就业后，教育,粮食安全状况,性别,和年龄,任何常见问题解答项目都没有差异，常见问题解答总评分,饮食限制，去抑制,和饥饿在任何时间点，除了一个项目的FAQ在12个月。素食主义者组的参与者在进餐后的满意度比杂食性组增加更多（平均差异0.80±0.32，95％CI0.18，1.42；P=0.01）。这是第一批研究饮食可接受性差异的研究之一，饥饿,和其他饮食因素在非洲裔美国成年人中随机分为素食或杂食灵魂饮食。研究结果强调，植物性饮食方式同样可以接受杂食性饮食方式，并且在饥饿方面也有类似的变化，克制,和抑制。这些结果表明，以植物为基础的饮食方式可以是推荐预防心血管疾病的可接受的饮食模式，并且可能会提高餐后满意度。
