Breastfeeding and weaning in Late Holocene hunter-gatherers of the lower Paraná wetland, South America.
Daniel LoponteBárbara MazzaPublished in: American journal of physical anthropology (2021)
The results indicate that exclusive breastfeeding continued until the age of ~2 years, and weaning probably until 4 years of age. Supplementary foods included C3 plants and probably animal fats and C4 carbohydrates. A high fractionation of 4.9‰ in δ15 N values was recognized between breastfeeding infants and adult females, perhaps reflecting episodic hyper-protein diets in women linked to men's food provisioning during women's gestational/postpartum period. Additionally, male adults present a higher protein intake than females. Although this difference is not statistically significant with the current sample size, it could be a clue related to a sexual division in food procurement.
