Theres plenty of nutritional alternatives to be had instead.
But certainly cutting out dairy is advantageous rather than not.
Im doing this for the health benefits rather than some vegans who do so for animal rights etc, though watched latest country file and that was saying hiw veganism is now starting to have a positive impact on the dairy market.
As a plus, hazelnut milk in coffee is quite nice so thats good
But if you like junkie food, you can still eat like that whilst being a vegan
