ESPINOSA-MARRON, Alan et al. Nutritional imbalances in a Mexican vegan group: urgent need for country-specific dietary guidelines. Nutr. Hosp. [online]. 2022, vol.39, n.2, pp.473-478.  Epub 09-Mayo-2022. ISSN 1699-5198.


vegan diets exclude the consumption of animal-derived products, and health advantages have been reported when followed. However, heterogeneous eating habits, food availability, and sociocultural characteristics among regions could lead to different physiological results.

Case reports:

twelve patients following a strict vegan diet for an uninterrupted period of ≥ 3 years were subjected to clinical assessment. Patients significantly exceeded the suggested intake for sugar, presented six mineral deficiencies, and exhibited three vitamins below the recommended consumption. We further identified hyperglycemia, hypertriglyceridemia, subnormal serum vitamin B12 concentrations, as well as macrocytosis and microcytic anemia in several participants.


this Mexican vegan diet is strongly influenced by endemic and cultural adaptations that could limit the benefits reported in other populations. Professional guidance is required to avoid specific deficiencies with potential repercussions. We urge country-specific vegan guidelines considering local eating habits, food availability, and sociocultural perspectives around food.
