Abstract
MARCHESINO, Mariana A et al. Modifications of the superoxide anion level in breast milk by the intake of flavonoids and carotenoids. Salud pública Méx [online]. 2017, vol.59, n.5, pp.526-531. ISSN 0036-3634. https://doi.org/10.21149/8403.
Objective:
To associate the intake of flavonoids and carotenoids with the breast milk level of superoxide anion, as an oxidative stress marker.
Materials and methods:
100 women from Cordoba (Argentina), who breastfed within the first postpartum 6 months, were studied during the 2013-2015 period, by evaluating their sanitary data, food intake and anion level in milk with multiple logistic regression.
Results:
The intake of flavonoids, provitamin A carotenoids and non-provitamin carotenoids was 72 (61) mg/d, 1813 (1 657) µg/d y 5427 (3 664) µg/d, respectively. The anion was associated with the intake of flavanols (OR=1.081; CI95 1.001-1.167) y flavanones (OR=1.025; CI95 1.001-1.048). This effect was not seen with other flavonoids and carotenoids.
Conclusions:
Intake of flavanols and flavanones increases milk oxidation risk, which is relevant to develop diet recommendations.
