Dairy vs non dairy
If you are vegan you can opt for the nondairy category as it contains all kinds of cheeses and milk (soya, almond, rice etc…)
Lactose intolerant individuals require non dairy products but can have dairy items low in lactose (if they are intolerant to lactose) such as lactose free cow milk, camel milk/cheese,sheep dairy products or goat milk/cheese.
If you are casein (cow milk protein) intolerant then it is best to avoid cow derived dairy products and opt for plant and nut milk along with goat,sheep and camel dairy products.
