ALA es precursor de EPA y DHA y sus fuentes dietarias son limitadas. Aceites ricos en ALA (48–64%) son una alternativa para incrementar su consumo. En este trabajo se evaluó la conversión de ALA a EPA y DHA, y la relación (EPA+DHA/ALA) en tejidos de ratas macho Wistar alimentadas con aceites con alto contenido en ALA. Cuatro grupos (n=12/grupo) recibieron durante 21 días aceite de: a) maíz (CO, 3% ALA); b) soja (SO, 6% ALA); c) sacha inchi (SIO, 48% ALA) y; d) chía (ChO, 64% ALA). SO, SIO y ChO incrementaron ALA (p<0,05) en los tejidos. Solo SIO y ChO incrementaron el EPA y DHA, disminuyendo la relación n-6/n-3 (p<0,05). Se propone SIO y ChO como fuentes de ALA para incrementar EPA y DHA en los tejidos.
