Answer summary: Most animal food and plant food contain zinc.
Detailed explanation: Because zinc is an essential nutrient element for all animals and plants, it can be imagined that zinc exists in all grains, green vegetables and various animal foods with different contents.
Special examples:
1. The food with particularly rich content is oyster (note: oyster is a marine mollusk); Among plant foods, nuts containing more zinc are pumpkin seeds, peanuts, sunflower seeds, walnuts and so on; In grain, the zinc content of corn is higher.
2. Few foods such as white wine and white sugar and vinegar contain almost no zinc. Although all animal and plant foods contain zinc, these two sentences do not contradict each other, because white wine and white vinegar and sugar are not original ingredients.
