- Hemp seeds
- Sunflower seeds
- Sesame seeds
- Brown rice
- Whole wheat products
- Mushrooms (especially shiitake and crimini mushrooms)
Tofu and Tempeh:
Tofu and tempeh are soy-based products that contain moderate amounts of zinc.
Zinc is often added to some plant-based meat substitutes.
Nutritional yeast is a common ingredient in vegan diets and is often fortified with zinc.
Breads and Cereals:
Zinc is often added to some whole-grain breads and cereals to increase their nutritional value.
Vegetables and Fruits:
While fruits and vegetables generally contain lower amounts of zinc, including a variety in your diet contributes to overall nutrition.
Certain types of seaweed, such as nori and spirulina, contain small amounts of zinc.
Tips to Enhance Zinc Absorption:
Soaking and Sprouting
Soaking and sprouting legumes, nuts, and seeds can help reduce the phytate content, potentially enhancing zinc absorption.
Certain cooking methods, such as fermenting and leavening, can also help reduce phytates and improve zinc bioavailability.
Consuming a variety of vegan foods rich in zinc can provide a broader range of nutrients and improve overall zinc intake.
If you have concerns about meeting your zinc needs on a vegetarian or vegan diet, or suspect a deficiency, it’s advisable to consult with a registered dietitian or healthcare professional.
