Vegetarian diets are associated with healthy mood states: a cross-sectional study in seventh day adventist adults.
Beezhold BL, Johnston CS, Daigle DR.
Abstract
BACKGROUND: The physical health status of vegetarians has been extensively reported, but there is limited research regarding the mental health status of vegetarians, particularly with regard to mood. Vegetarian diets exclude fish, the major dietary source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), critical regulators of brain cell structure and function. Omnivorous diets low in EPA and DHA are linked to impaired mood states in observational and experimental studies.
METHODS: We examined associations between mood state and polyunsaturated fatty acid intake as a result of adherence to a vegetarian or omnivorous diet in a cross-sectional study of 138 healthy Seventh Day Adventist men and women residing in the Southwest. Participants completed a quantitative food frequency questionnaire, Depression Anxiety Stress Scale (DASS), and Profile of Mood States (POMS) questionnaires.
RESULTS: Vegetarians (VEG:n = 60) reported significantly less negative emotion than omnivores (OMN:n = 78) as measured by both mean total DASS and POMS scores (8.32 +/- 0.88 vs 17.51 +/- 1.88, p = .000 and 0.10 +/- 1.99 vs 15.33 +/- 3.10, p = .007, respectively). VEG reported significantly lower mean intakes of EPA (p < .001), DHA (p < .001), as well as the omega-6 fatty acid, arachidonic acid (AA; p < .001), and reported higher mean intakes of shorter-chain alpha-linolenic acid (p < .001) and linoleic acid (p < .001) than OMN. Mean total DASS and POMS scores were positively related to mean intakes of EPA (p < 0.05), DHA (p < 0.05), and AA (p < 0.05), and inversely related to intakes of ALA (p < 0.05), and LA (p < 0.05), indicating that participants with low intakes of EPA, DHA, and AA and high intakes of ALA and LA had better mood.
CONCLUSIONS: The vegetarian diet profile does not appear to adversely affect mood despite low intake of long-chain omega-3 fatty acids.

El estado de salud físico de vegetarianos ha sido extensamente relatado, pero la investigación es limitada en cuanto al estado de salud mental de los vegetarianos, en particular con respeto al estado emocional. Dietas vegetarianas excluyen el pescado, la fuente principal dietética de ácido eicosapentaenoic (EPA) y el ácido docosahexaenoic (DHA), los reguladores críticos de estructura de célula cerebral y función. Dietas omnívoras bajas en el EPA Y DHA guardan relación con estados emocionales perjudicados en estudios de observación y experimentales.

Conclusiones: El perfil de una dieta vegetariana no parece afectar desfavorablemente el estado emocional a pesar de la entrada baja de Omega de cadena larga 3 ácidos grasos.
¡Uf, salvados! jeje!
