So far as veg food is concerned, it is also proved to be a healthy and nutritious diet, but has very few items which can provide us with proteins, but if you see non-veg food like eggs, chicken, and many more, such foods have a large content of proteins in them.

Man basically is herbivorous（食草的）. If we look at the animal kingdom
We can see that all the herbivorous animals have the similar dental（牙齿的）
structure, which clearly shows that the human being also ought to be vegetarian
by birth. It is only the living conditions that make man carnivorous（食肉的）.
The vegetarian foods are easily digestible.

Non-veg food items are better than veg items. A healthy person requires complete diet and veg+ meat makes the diet complete. The only caution that needs to be taken is not to have non-veg items on a daily basis. Once in a week or couple of weeks will be best.

When we eat non-veg, we are all veg by nature. The chicken that we eat feeds on grains, the mutton that we eat feeds on grass, and the fish that we eat feeds on simple plants. So non-veg food by logic（逻辑）is better and suited for hauman beings.

Non-veg food is equally important in our diet as it helps in many ways, especially fish and other seafood as fish contains omega 3 which makes our immune system（免疫系统）stronger. Do you know that most of the veg food put together does not contain as much omega 3 as fish alone contains!
