Abstract
BACKGROUND:

Omnivorous diets are high in arachidonic acid (AA) compared to vegetarian diets. Research shows that high intakes of AA promote changes in brain that can disturb mood. Omnivores who eat fish regularly increase their intakes of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fats that oppose the negative effects of AA in vivo. In a recent cross-sectional study, omnivores reported significantly worse mood than vegetarians despite higher intakes of EPA and DHA. This study investigated the impact of restricting meat, fish, and poultry on mood.
FINDINGS:

Thirty-nine omnivores were randomly assigned to a control group consuming meat, fish, and poultry daily (OMN); a group consuming fish 3-4 times weekly but avoiding meat and poultry (FISH), or a vegetarian group avoiding meat, fish, and poultry (VEG). At baseline and after two weeks, participants completed a food frequency questionnaire, the Profile of Mood States questionnaire and the Depression Anxiety and Stress Scales. After the diet intervention, VEG participants reduced their EPA, DHA, and AA intakes, while FISH participants increased their EPA and DHA intakes. Mood scores were unchanged for OMN or FISH participants, but several mood scores for VEG participants improved significantly after two weeks.
CONCLUSIONS:

Restricting meat, fish, and poultry improved some domains of short-term mood state in modern omnivores. To our knowledge, this is the first trial to examine the impact of restricting meat, fish, and poultry on mood state in omnivores.

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.

De paso me gustaría agregar algo con respecto al ánimo y nuestra dieta. El déficit de B12, entre otras cosas, puede empeorar nuestro estado de ánimo y llevarnos a la depresión. Así que si cuidamos eso será estupendo jejeje.

We will burn in hell.

El estudio se ha hecho con adventistas porque la mayoria son vegetarianos (o veganos) desde hace varias generaciones, por tanto es una población muy pura en ese sentido, muy apta para estudiar los efectos de una alimentación veg a largo plazo.

Ouch. Con lo mal que llevo yo los calores...

Eeexacto . Es por eso Sarmale. Es fácil pillar una buena población vegetariana entre los adventistas.

Nadie se anima a hacer un "short summary" del estudio ese?

Menos mal que Walkiria lo entendió. Estoy comenzando a pensar que no hablo castellano.

¿PERDÓN? No comprendemos sarmalés aquí...

Lo siento Sarmale. El problema soy yo, que en muchas ocasiones pillo las cosas demasiado literalmente.

Nekete, si saco un ratito hago un resumencillo.
