Step-by-step explanation:
The MyPlate food group that contains the most nutrient-dense sources of zinc is Protein.
Protein-rich foods such as meat, poultry, seafood, beans, peas, nuts, and seeds are excellent sources of zinc. These foods provide the body with essential amino acids and are highly nutritious.
