Given the growing popularity of plant-based diets, this study investigated the dietary habits and self-reported health outcomes of health-conscious adults consuming plant-based diets.
A cross-sectional online survey (n = 315) was distributed to members of Plant-Based Health Professionals UK, a community interest company. Dietary intake was assessed through a food frequency questionnaire. Data were summarised descriptively. Dietary habits among respondents following a whole food plant-based (WFPB) and vegan diet were compared using hypothesis tests.
Respondents reported following a WFPB (61%), vegan (28%) and semi plant-based (11%) diet. Median time on current dietary pattern was 5 years. Daily or more frequent consumption was reported for the following foods: fruits 77%, berries 51%, green vegetables 48%, cruciferous vegetables 45%, other vegetables 64%, beans/legumes 41%, whole grains 62%, nuts and all seeds 63%. Consumption of ultra-processed foods and plant-based meat alternatives was low. About 93% of those on a WFPB or vegan diet supplemented with vitamin B and 61% with vitamin D. The median body mass index was 22.4 kg/m. Fifty per cent of participants reported weight loss after adopting a plant-based diet, with a median loss of 6.4 kg. Thirty-five per cent reported reversing or improving an underlying health condition, and 15% were able to stop or reduce prescribed medication use as a result of dietary changes.
This study suggests that a well-planned plant-based diet is achievable and sustainable in a community setting and can be associated with health benefits. How to best encourage such sustainable diets among the broad population requires further research.
鉴于植物性饮食越来越受欢迎，本研究调查了食用植物性饮食的注重健康的成年人的饮食习惯和自我报告的健康结果。
一项横断面在线调查（n=315）分发给英国植物性健康专业人员社区利益公司的成员。通过食物频率问卷评估膳食摄入量。数据以描述性方式进行总结。使用假设检验比较遵循全食物植物性（WFPB）和纯素食饮食的受访者的饮食习惯。
受访者报告遵循 WFPB（61%）、纯素食（28%）和半植物性饮食（11%）。当前饮食模式的中位数时间为 5 年。报告以下食物的每日或更频繁的消费：水果 77%、浆果 51%、绿色蔬菜 48%、十字花科蔬菜 45%、其他蔬菜 64%、豆类/豆类 41%、全谷物 62%、坚果和所有种子 63%。超加工食品和植物性肉类替代品的消费较低。约 93%的 WFPB 或纯素食者补充维生素 B，61%补充维生素 D。中位数体重指数为 22.4kg/m。50%的参与者报告在采用植物性饮食后体重减轻，中位数减轻 6.4kg。35%报告逆转或改善潜在健康状况，15%因饮食变化能够停止或减少规定的药物使用。
本研究表明，在社区环境中，精心计划的植物性饮食是可行和可持续的，并与健康益处相关。如何在更广泛的人群中最好地鼓励这种可持续饮食需要进一步研究。
