However, this only works efficiently if the ratio between omega 3 (mainly in flaxseed, chia seeds) to omega 6 (mainly in sunflower oil) does not exceed 1:5. [97] Major vegan sources of the essential omega-3 fatty acid ALA include walnuts, flaxseeds and flaxseed oil, canola oil, algae oil, hempseeds and hempseed oil, olive oil, and avocado. [1]

Appropriately planned vegetarian diets are healthful and nutritionally adequate for all stages of the human life cycle, including during pregnancy, lactation, infancy, childhood, and adolescence. [1]
Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds).

Vegetarian diets generally exclude meat, poultry, and seafood, while vegan diets further eliminate other animal products like eggs and dairy. In this review, “vegetarian” encompassed all types.

Docosahexaenoic acid (DHA) is an omega−3 fatty acid that is an important component of the human brain, cerebral cortex, skin, and retina. It is given the fatty acid notation 22:6(n−3). [1] It can be synthesized from alpha-linolenic acid or obtained directly from maternal milk (breast milk), fatty fish, fish oil, or algae oil.
Deficiency in omega−3 fatty acids are very common. The average American has a dietry ratio between omega−6 fatty acids and omega−3 fatty acids of 20:1. When the two EFAs were discovered in 1923, they were designated "vitamin F", but in 1929, research on rats showed that the two EFAs are better classified as fats rather than vitamins. [8]
