If you're a strict vegetarian or vegan, you're not getting enough zinc from your diet.
This is because the highest amounts of zinc are found in red meat and shellfish.
Another problem is most vegetarians eat a lot of whole grains and plant proteins. These foods are high in phytic acid, which interferes with zinc absorption. If you are like most vegetarians you may need up to 50% more zinc than non-vegetarians
Zinc is an essential trace mineral that's critical for growth and development. Your body also needs zinc for a healthy immune system, healthy skin, reproduction, blood clotting, vision, taste, smell, insulin and thyroid function, and to fight infections.
"The light-headed feeling of detachment that enshrouds some vegetarians can be caused by hidden Zinc hunger, rather than by some mystical quality of the brown rice or other food consumed."
- Carl C. Pfeiffer, Ph.D., M.D.
The Recommended Daily Allowance (RDA) depends on your age and sex.
|9-13||8 mg||8 mg|
|14-18||11 mg||9 mg|
|19 +||11 mg||8 mg|
The Daily Value (DV) for Zinc is 15 mg for both adults and children that are 4 and older. For strict vegetarians that eat a lot of fiber, grains and legumes, the requirement is 50% higher. This is because these foods are high in phytic acid, which interferes with your body's ability to absorb Zinc.
Symptoms of a mild Zinc deficiency include slow wound healing, loss of appetite, and a weakened immune system. Severe Zinc deficiencies are rare.
|Hemp Seeds (1 oz.)||3.2 mg|
|Crimini mushrooms (5 oz.)||1.56 mg|
|Spinach (1 cup)||1.37 mg|
|Pumpkin seeds (1/4 cup)||2.57 mg|
|Sesame seeds (1/4 cup)||2.8 mg|
|Cashews, dry roasted (1 ounce)||1.6 mg|
|Bran Flakes (1 cup)||2.0 mg|
|Wheat Germ (2 tablespoons)||2.7 mg|
|Adzuki Beans||2 mg|
|Granola (1/2 cup)||1.3 mg|
|Tempeh (1/2 cup cooked)||1 mg|
|Tofu (1/2 cup firm)||1 mg|
Whole grains are richer in Zinc than refined grains that have not been fortified. This is because most of the Zinc is found in the germ and bran portions of the grains. During the milling process these parts of the grain are lost, and so is up to 80% of the Zinc.
Most vegetarians can't get enough Zinc from their diets, so they eat foods fortified with it, or take a Zinc supplement.
There are different types of Zinc supplements, including Zinc gluconate, Zinc sulfate, Zinc acetate, Zinc picolinate, Zinc citrate, Zinc glycerate, and Zinc monomethionine.
There's no evidence that there's a difference in Zinc absorption or bioavailability between the different types of Zinc. But, some are easier on the stomach than others. So if you experience stomach upset, try a different type, like Zinc citrate.
Getting enough Zinc with plant sources is a challenge. But supplements and fortified foods can easily fill the gap.

Chia seeds are becoming popular with vegetarians mainly because it's the best source of Omega-3 ALA. But Chia has much more to offer. It's also high in vegetarian protein, fiber, vitamins and minerals.
Switching to a vegetarian diet doesn't necessarily mean that you'll lose weight. In fact, during my first six months as a vegetarian I actually gained ten pounds. Since then, I've lost the weight, and kept it off by following these vegetarian weight loss tips:
It's no coincidence that the same vegetarian foods that we need to stay healthy, also keep our skin youthful and beautiful. In fact, the right vegetarian diet can keep your skin moisturized, radiant, and wrinkle free.
