Résumé
The diverse polar lipids found in the milk fat globule membrane have been the subject of numerous studies demonstrating their nutritional interest for the general population or for certain targets with specific needs (seniors, infants, sportsmen and women, etc.). These polar lipids are concentrated in certain dairy co-products (buttermilk or butterserum for example) but are also dispersed in other dairy products. The bioactivity of the different components of dairy polar lipids (anticholesterolemic effect of phosphatidylcholine and sphingomyelin, antiviral effects and regulation of the microbiota induced by gangliosides, memory improvement effect or cognitive function of phosphatidylserine, etc...) will be presented and discussed in the light of the recent bibliography.
