Which of the following is not a good source of zinc?

Zinc is an essential mineral that plays a critical role in various bodily functions, including immune response, protein synthesis, and DNA synthesis. Foods rich in zinc include red meat, shellfish, and poultry, which are excellent sources due to their high zinc content. These animal-based foods provide zinc in a form that is easily absorbed by the body.

Olive oil, while offering many health benefits such as heart-healthy fats and antioxidants, does not contain significant amounts of zinc. Plant-based oils generally lack this mineral because they are typically derived from the fat of plants and do not contain the nutrient-rich components found in meats and seafood.

Therefore, the best answer is that olive oil is not a good source of zinc, making it distinct from the other options that are recognized for their rich zinc content.
