While fish is the main dietary supply of the long-chain omega-3s eicosapentaenoic acid and docosahexaenoic acid, which have been shown to be essential in supporting brain health, low intake of eicosapentaenoic acid and docosahexaenoic acid in vegetarians won't adversely affect mood, based on a new study (Nutr J. 2010;9:26. DOI:10.1186/1475-2891-9-26).

A study team from Arizona State University conducted a cross-sectional study to compare the mood of vegetarians who never eat fish with the mood of healthy omnivorous adults.

A total of 138 healthy Seventh Day Adventist adults living in Arizona and California (64 vegetarians and 79 non-vegetarians) were enrolled in the study and completed a health history questionnaire, food frequency questionnaire and two psychometric tests, the Depression Anxiety Stress Scale and also the Profile of Mood States..

Vegetarians had significantly lower mean intakes of eicosapentaenoic acid, docosahexaenoic acid and also the omega-6 arachidonic acid; they had higher intakes of the omega-3 alpha-linolenic acid and the omega-6 linoleic acid.

"Seed oils are the richest sources of α-linolenic acid, notably those of rapeseed (canola), soybeans, walnuts, flaxseed (Linseed oil), clary sage seeds, perilla, chia, and hemp."

However, the vegetarians also reported significantly less negative emotion than omnivores in both psychometric tests. Mean total psychometric scores were positively in connection with the mean intakes of eicosapentaenoic acid, docosahexaenoic acid and arachidonic acid , and inversely associated with alpha-linolenic acid and linolenic acid intake.

The research team noted there is also the possibility that vegetarians may make smarter dietary choices and could generally be healthier and happier.
