Why zinc is present in non vegetarian sources?

Zinc is present in non-vegetarian sources primarily because it is an essential mineral found in animal tissues. Animal proteins, especially red meats, poultry, and seafood, are rich in zinc due to the mineral's role in various biological processes, including immune function and protein synthesis. Additionally, the bioavailability of zinc from animal sources is higher compared to plant sources, making it more easily absorbed by the body. As a result, non-vegetarian diets typically provide a more concentrated and accessible form of zinc.
