Nutrient adequacy and environmental foot-print of Mediterranean, pesco-, ovo-lacto-, and vegan menus: a modelling study.

ABSTRACT:

Background

Consumer food choices are changing towards a more plant-based diet (PBD) due to growing awareness of their less detrimental effects on health and the environment. However, PBDs-particularly vegan diets-may lead to nutritional deficiencies compared to non-PBDs. These differences may, in part, be influenced by the typically lower caloric content of PBDs.

Objective

To compare the nutritional adequacy and environmental footprints of four 7-day menu models (~ 2,000 kcal/day) Mediterranean (omnivorous) diet, two vegetarian-like diets, and one vegan.

Methods

Menus were designed based on the recommendations of the Spanish Society for Community Nutrition (SENC) and Vegetarian Union (UVE), substituting animal-based foods with plant-based alternatives. Nutritional int
