Plant-based dietary patterns are associated with chronic disease risk reduction, prevention, and reversal. As such, the Nutritarian diet is a dietary plan grounded in the daily consumption of micronutrient-dense, plant-rich foods that satisfy nutrient needs with a corresponding improvement in overall health. The Nutritarian Women's Health Study was a fully-online intervention that included supportive, automated email messages, with participants self-reporting dietary adherence and anthropometric measurements quarterly. Changes in Body Mass Index (BMI) were not significant. The groups with the lowest baseline Waist-to-Height-Ratio (WHtR) showed an initial increase followed by a decrease. Responses related to dietary adherence showed that most participants easily consumed greens, beans, onions/garlic, berries, and seeds, avoided animal products, alcohol, and refined foods, but had difficulty with regularly consuming mushrooms and tomatoes. A midpoint questionnaire revealed participants consumed an overwhelming amount of their meals/snacks according to the dietary plan and about half found it easy/very easy to eat strictly Nutritarian. A large majority reported a positive change in health from participating in the study. The barriers to following the dietary plan include a busy lifestyle and the opposing views/pressures from friends, family, co-workers, and/or spouse/partner. It is important to evaluate this fully-online approach when considering future interventions.
以植物为基础的饮食模式与降低、预防和逆转慢性病风险相关。因此，营养主义饮食是一种基于每日食用富含微量营养素、植物性食物的饮食计划，这些食物能满足营养需求并相应改善整体健康状况。营养主义女性健康研究是一项全在线干预措施，包括支持性的自动电子邮件，参与者每季度自行报告饮食依从性和人体测量数据。体重指数（BMI）的变化不显著。基线腰高比（WHtR）最低的组最初有所增加，随后下降。与饮食依从性相关的反馈表明，大多数参与者很容易食用绿叶蔬菜、豆类、洋葱/大蒜、浆果和种子，避免食用动物产品、酒精和精制食品，但难以经常食用蘑菇和西红柿。一份中期调查问卷显示，参与者按照饮食计划摄入了绝大多数餐食/零食，约一半的人发现严格遵循营养主义饮食很容易/非常容易。绝大多数人报告称参与该研究后健康状况有积极变化。遵循饮食计划的障碍包括忙碌的生活方式以及来自朋友、家人、同事和/或配偶/伴侣的反对意见/压力。在考虑未来的干预措施时，评估这种全在线方法很重要。
