An ultrasound of the carotid artery wall was then performed three years later. The results show that whereas the total consumption of dairy products, milk or cheese does not alter the thickness of the wall of the carotid artery, yoghurt consumption does.
Volunteers who consumed more than 100 g of yogurt per day showed a lesser carotid intima-media thickness compared with consumers of smaller quantities of yogurt. This relationship remained even after adjusting for various confounding factors.
