Meat, shellfish, and dairy have some of the highest sources of zinc, but what about the best plant sources of zinc? With so many people choosing to follow a plant-based diet, knowing which plant sources provide the best source of zinc is essential to health. Continue reading to find out the 17 Best Plant Sources of Zinc.
What Does Zinc Do for the Body?
Before we get to the best plant sources of zinc, let’s investigate why zinc is vital for our bodies. According to the National Institutes of Health (NIH), zinc is an essential nutrient. Therefore, our bodies do not make zinc, so we need to get it from the foods we eat.
Zinc is necessary for cellular metabolism or chemical reactions to maintain life. In addition to cellular metabolism, zinc is essential for immune function. Having a healthy immune system helps to fight off infections and prevent serious illness.
Another critical role of zinc is protein synthesis and promoting wound healing. As a registered dietitian, many of the people I work with have surgical procedures and may require additional zinc to help their bodies heal and repair. In addition, our skin holds 5% of the zinc content in our bodies and helps with cell growth and collagen formation, essential for wound healing.
After having surgery or having certain conditions or illnesses, some people may need to take zinc supplements if they cannot eat enough to get zinc from their foods. However, taking too much zinc can result in toxicity. So, speak with your physician or dietitian before taking zinc supplements. In addition, getting tested for zinc deficiency before taking zinc supplements is recommended.
Also, zinc is necessary for growth and normal development during pregnancy and in children and adolescents. During pregnancy, women need more zinc to help maintain their zinc levels and promote normal development, requiring 11 mg of zinc per day compared to 8 mg in non-pregnant women.
And did you know that zinc even helps us with our sense of taste and smell!
How Much Zinc Do You Need?
So that leads us to how much zinc do we need to have every day. As mentioned above, women at least 19 years and older need 8 mg per day, pregnant women need 11 mg, and lactating women require 12 mg of zinc daily. The Recommended Daily Allowance for men is 11 mg per day.
However, if you are vegetarian, vegan, or do not eat much meat or seafood, you may require up to 50% more of the RDA. Plant foods high in zinc have decreased absorption due to the phytates in these foods. Phytates are in foods such as seeds, grains, and legumes. However, there may be evidence that vegetarians and vegans can adapt to lower zinc levels by increasing absorption and retaining more zinc.
How do vegans and vegetarians increase zinc absorption?
Some easy ways to increase absorption of zinc from plant sources include:
- Choosing yeast-leavened or sourdough bread instead of unleavened products like crackers since the leavening process partially breaks down phytates.
- Also, pre-soaking and rinsing legumes before cooking are helpful. Allowing them to soak until sprouts form or choosing sprouted grains and seeds can also help improve zinc absorption from legumes and grains.
- Taking iron supplements separately from meals because iron decreases the absorption of zinc.
- Eating high protein sources from beans, nuts, and seeds can help increase the absorption of plant sources of zinc as protein has a positive effect on absorption.
Best Plant Sources of Zinc
Ok, get ready to boost your health and immunity by adding more zinc to your diet. Here are 17 of the best plant sources of zinc.
