• We evaluated maternal flaxseed oil intake during lactation on body composition, lipid profile, glucose homeostasis and adipose tissue inflammation in male and female progeny at adulthood. Lactating rats were divided into the following: control 7% soybean oil (C), hyper 19% soybean oil (HS) and hyper 17% flaxseed oil+2% soybean oil (HF). Weaned pups received a standard diet. Offspring were killed in PN180. Male HF presented higher visceral adipose tissue (VAT) and triacylglycerol, and female HF showed insulin resistance. Both male and female HF had hyperleptinemia, and only male HF had hyperprolactinemia. In VAT, male HF presented lower PPAR-γ expressions and higher TNF-α, IL-6, IL-1β and IL-10 expressions; in subcutaneous adipose tissue (SAT), they presented lower PPAR-γ and TNF-α expressions. Female HF presented higher leptin, as well as lower adiponectin, TNF-α, IL-6 and IL-1β expressions in VAT and lower TNF-α in SAT. Flaxseed oil during lactation leads to gender-specific effects with more adiposity and dyslipidemia in male and insulin resistance in female. Higher prolactin and inflammatory cytokines in male could play a role in these gender differences. We suggest that the use of flaxseed oil during lactation increases metabolic syndrome risk in the adult progeny. Changes found in male and female offspring at adulthood. [Display omitted]
