Enlightening if unsurprising. I have certainly found that eliminating meat from my diet has been an order of magnitude easier than eliminating dairy. Very frustrating.

Dairy really is the triple whammy of harms: terrible for the environment and animal welfare, and probably unhealthy too. This last claim is controversial but it shouldn’t be: humans do not have much evolutionary preparation for imbibing milk as adults, let alone the milk of another species. This is a weird modern habit unique to humans.
