A new study, published in the British Journal of Nutrition, claims to show that organic dairy and meat products in a mothers diet positively affect the nutritional quality of her breast milk by markedly increasing its content of beneficial fatty acids.

Specifically, a diet in which 90% or more of dairy and meat products are organic was correlated with measurably higher levels of conjugated linoleic acid (CLA). The study involved 312 breastfeeding women with one-month old infants from the Netherlands.
