Summary
This cross-sectional study, published in Nutrients in 2014 by Clarys and colleagues, examines nutrient intake profiles across a spectrum of dietary patterns ranging from veganism to omnivory, likely drawing on dietary recall or food frequency questionnaire data from a Belgian sample. The paper provides a comparative analysis of macro- and micronutrient adequacy across diet groups, highlighting where plant-based diets may confer benefits (e.g. fibre, certain vitamins) and where nutritional gaps may arise (e.g. vitamin B12, iron, calcium). It is a commonly cited reference in nutrition research examining the health implications of plant-based dietary choices.
UK applicability
Although the study was conducted in Belgium, the dietary patterns and nutrient gaps identified are broadly applicable to UK populations adopting plant-based diets, and the findings are relevant to UK dietary guidelines and public health nutrition policy on vegetarian and vegan diets.
Key measures
Dietary nutrient intakes (macro- and micronutrients); energy intake (kcal/day); protein, fat, carbohydrate, fibre, vitamin B12, iron, calcium, zinc, and omega-3 fatty acid intakes by diet group
Outcomes reported
The study measured and compared dietary nutrient intakes across multiple diet groups including vegans, vegetarians, semi-vegetarians, and omnivores. Outcomes likely included macro- and micronutrient adequacy, energy intake, and potential nutritional deficiencies or surpluses by diet type.
