Vegetarian diets have low environmental footprints and are potential solutions to address climate change and the 2030 Agenda on the Sustainable Development Goals. Currently, there is no information regarding the nutritional quality of vegetarian diets in Portugal. As the trend for vegetarianism increases in the country, the aim of this study is to examine and compare nutritional and metabolic outcomes among vegetarian and non-vegetarian populations. We aim to implement a cross-sectional study that includes a total of 400 (distributed among the three diferent groups of omnivorous, lacto-ovovegatarians and vegans) healthy Portuguese adults aged 18-64 years. Blood and urine samples will be collected. Participants will be assessed for blood pressure, anthropometric parameters, micronutrient status, blood lipids, glicaemia and insuline resistance and will complete a validated food frequency questionnaire as well as a sociodemographic and lifestyle questionnaire. Dietary and nutrient analysis will be conducted to assess diet quality and nutritional inadequacies. The current proposal provides an unique opportunity to characterize and compare different population groups clustered by dietary behaviour and provide evidence that help achieve healthy and sustainable diets in Portugal.
