The Early Christians ate rice, bread, meat products, few dairy products and drank wine or water. The Christians got punished by the Jews for putting rice (or dairy products) in the same bowl as meat.
If you eat both meat or dairy products and plants (fruits, veggies), then yes. If you don't eat meat/dairy products or only eat meat/dairy products, then no.

It's the basis of the avoidance of cooking meat and dairy products together, eating meat and dairy products together, and profiting from a combination of meat and dairy products.
We can eat dairy 30 minutes after meat, or meat six hours after dairy.
Jews dont.

Additionally, some Jews will only use products labeled 'chalav Yisroel', these are dairy items that have Jews directly involved in their production.
