Objective:

studies have been published in Europe comparing the mean macronutrient and micronutrient intake values of the general population with those of the vegan population, but none has been conducted in a country that mainly follows the Mediterranean diet. Therefore, the aim of this study was to carry out this comparison in Spain.

Methods:

a cross-sectional study of a sample of Spanish vegans was designed in 2015. To compare the distribution of nutrients with those of the general population, we used data from the Spanish Agency for Food Safety and Nutrition, which was considered to be normally distributed as it was a large population with biological parameters. All participants were asked about their dietary intake for the previous day (24 hour reminder) and the nutrients were calculated using specialized software. The distributions were compared using the Kolmogorov-Smirnov test.

Results:

the sample comprised 102 vegans, 67 of whom were women. The vegan population consumed more carbohydrates and fiber, less total fat (women only), fewer saturated fatty acids, and more polyunsaturated fatty acids. They had much lower cholesterol intake, lower calcium and iodine intake, higher iron and folic acid intake, and much lower intake of vitamins B12 and D.

Conclusions:

Spanish vegans had nutritional deficiencies compared to the general population and should therefore ensure their diet includes the necessary supplements.
