Epidemiology regarding raw milk and its protective effect on allergies and asthma is more likely to be true than vegetable epidemiology because it is harder to identify confounding factors like healthy user bias.

“when i look at epidemiology like this regarding raw milk and its protective effect on allergies and asthma the first thing i think is well maybe it's being on the farm maybe more people on the farm are drinking raw milk and this is a type of healthy user bias but in the abstract they say they have control for this and that people who are not on farms also see a benefit associated with raw milk so i can't come up with a more compelling hypothesis for why raw milk is protective for humans than the fact that it is actually protected for humans because of the probiotics in the milk”
