which is healthy either vegeterian food or nonvegeterian food?

Hi rajka. Well, neither of it is good. You need to eat a well-balanced type of food. Each types of food are need by body. We need about 40% carbohydrate, 40% protein, and 20% fat. So without protein you didn't have a balanced diet.

i prefer nonvegeterian food like meat.i love it.and i'm not a cow which just eating vegetable or grass

It is not as simple as non-vegetarian food or vegetarian food. Both vegetarians and omnivores can have a good or bad diet. I've known vegetarians live on fries and pizza and that isn't a healthy diet. I think a lot of people eat too much meat but they also eat a lot of other processed and refined rubbish which means that even the vegetarian aspects of their diet are poor.
