Some vegetables
In general, vegetables are poor sources of zinc but some of them have reasonable amounts of zinc. Vegetables like potatoes, sweet potatoes, kale, and green beans are one of the best sources of zinc for people who avoid meat and other animal sources of food. One large potato contain almost 1 mg of zinc which covers almost 9% of the daily value (DV) for zinc. Other vegetables like kale and green beans contain almost 3% of the daily value (DV) for zinc, which is quite less but still suffices the needs of vegans.
