Resumen
Polyunsaturated Omega-3 fatty acids (ω-3 PUFA), particularly
docosahexaenoic acid (C22:6 ω-3, DHA), are critical nutrients
during pregnancy with a key role for visual and brain development.
Fish, especially oily fi sh, is an excellent dietary source of
DHA. However, its dietary consumption is low. Bioconversion
from alpha-linolenic acid (C18: 3 ω-3, ALA) to DHA is a limited
metabolic pathway in humans, however, it increases during
fertility and pregnancy. The chia seed oil (Salvia hispanica) is a
good vegetal source of ω-3 PUFA, containing a large proportion
(60-65% of total fatty acids) as ALA. The aim of this study was to
compare the acceptability of two different commercial oils: chia
oil (63% ALA) and canola oil (10% ALA) in a group of Chilean
pregnant women. A sample of 41 women was included. Each
participant performed: a) an assessment of the acceptability of
two commercial oils(hedonic scale), b) a dietary intake questionnaire
and, c) a test of knowledge related to ω-3 PUFAs.
Main results indicated that 57% of the participants properly
recognized food sources of ω-3 PUFA, and 12.2% met their
dietary requirements. The characteristics that had the highest
scores were the appearance of chia oil and the taste of canola
oil. However, there were no signifi cant differences between the
overall acceptability of both evaluated oils. It is concluded that
chia oil could be a new and useful alternative to increase dietary
ALA intake in pregnant women.
