Ómega-3

O que é? Como funciona Aviso

O Ómega 3 é um tipo de ácido gordo essencial para o normal crescimento e desenvolvimento do organismo e que, por não ser naturalmente produzido pelo nosso organismo, tem de ser obtido exclusivamente através da dieta.
Os ácidos gordos Ómega 3 são polinsaturados (possuem duas ou mais ligações duplas) e caracterizam-se por possuir a primeira ligação dupla no terceiro átomo de carbono. Existem diferentes tipos de Ómega 3: o ácido docosahexaenóico (DHA) e o ácido eicosapentaenóico (EPA), que provêm ambos de fontes animais, e ainda o ácido alfa-linolénico (ALA), que provém essencialmente de fontes vegetais. O nosso organismo tem a capacidade de converter o ALA em EPA e DHA.

As melhores fontes de ómega 3 são:

Peixes gordos (atum, salmão, sardinhas, anchovas, truta, cavala)
Óleo de fígado de bacalhau
Óleo de canola e linhaça
Feijões de soja e tofu
Nozes e sementes (ex: linhaça e chia)
