Dietary diversity and its determinants among women of reproductive age residing in the urban area of Nouakchott, Mauritania.

Background: The intake of nutrient-rich foods from diverse diets ensures adequate nutrition for women. This study aims to determine dietary diversity among women of reproductive age (WRA) using the MDD-W indicator and how it relates to their socio-economic characteristics in the city of Nouakchott, Mauritania.

Methods: A community-based cross-sectional study was conducted on 240 women of reproductive age, aged 15-49 years.

Fatty acid distribution in muscle, liver, and gonads of rays (Dasyatis marmorata, Rhinobatos cemiculus, and Rhinoptera marginata) from the East Tropical Atlantic Ocean.

If a great number of rays are fished in the Tropical East Atlantic Ocean for their caudal fins, only a small amount of ray flesh is processed. Among them, three species of rays, Dasyatis marmorata, Rhinobatos cemiculus, and Rhinoptera marginata, from the Mauritanian coast have been investigated for the fatty acid composition of their lipids. Gas chromatography and gas chromatography-mass spectrometry allowed identification of 50 molecules from muscles, livers, and gonads of these fishes.
