Abstract

Whole-food plant-rich dietary patterns have been shown to be associated with significant health benefits and disease-risk reduction. One such program, which has been gaining popularity, is the micronutrient-dense plant-rich (mNDPR) “Nutritarian” diet. The goal of this study is to determine the feasibility of implementing an online mNDPR “Nutritarian” intervention program and to determine the effectiveness of this program in reducing risk of chronic disease in women. The Nutritarian Women’s Health Study is a long-term online longitudinal hybrid effectiveness-implementation study. Participants are recruited through social media, medical professionals/offices, and nutrition-related events and conferences. Participants receive online nutrition education and complete regular self-reported questionnaires regarding lifestyle, nutrition practices, and health. The online intervention program appears to be feasible and effective. Some decline in dietary adherence, particularly for certain food types, was observed during the study. For groups at risk, based on body mass index or waist-to-height ratio, there were initial decreases in body mass index and waist-to-height that leveled off over time, in some cases returning to baseline measures. The study suggests the implementation of the Nutritarian dietary pattern, through an online intervention component, may be effective in reducing the risk of chronic disease, with implications for clinical and public health practice.
