What Vegetables Have Zinc? Zinc is an essential mineral that plays a role in the immune system and wound healing. Zinc occurs naturally in many foods, especially organ meats, seafood, shellfish, nuts, beans and seeds. When buying vegetables, buy the fresh form instead of frozen or canned. Many of the beneficial nutrients are lost when vegetables are cooked or processed into canned or frozen varieties. Vegetables high in zinc include:
What Vegetables Have Zinc
The best mineral for enhancing immunity is zinc. For your fix, turn to these meals.
Have you heard that getting a sufficient amount of zinc in your diet has been linked to a stronger immune system and quicker healing of wounds? Getting enough zinc has additional advantages.
According to research, zinc may be beneficial in the following circumstances:
the duration of the common cold.According to a meta-analysis, zinc supplements used over the counter lessen the severity and length of the common cold.Zinc supplementation may potentially shorten the duration of the common cold by 2.25 days, according to a comprehensive review that was published in July 2020 in The American Society of Tropical Medicine and Hygiene.
Keep heart disease at bay.Researchers discovered that zinc may be crucial in controlling the heartbeat in a preliminary lab study that was published in July 2015 in the Journal of Biological Chemistry. This finding may help in the fight against arrhythmia-related heart failure. Before it is certain that consuming meals containing zinc will result in these consequences for individuals, more research in humans is required. For the study, researchers employed cardiac tissue from sheep hearts when observing these benefits. Although the study was small, with only 60 participants, and the authors noted that more research is required, it found that supplementing with zinc and magnesium for 12 weeks helped people with type 2 diabetes and coronary heart disease decrease insulin and fasting blood sugar levels and increase HDL (“good”) cholesterol.
Take care of hypothyroidism.In a small trial of overweight women with hypothyroidism that was published online in the Journal of the American College of Nutrition in 2015, researchers found that zinc had a favorable impact on thyroid function.
promote eye health.According to the National Institutes of Health, more zinc may specifically help decrease the progression of age-related macular degeneration. (NIH).
aid in the healing of wounds.As previously indicated, research highlighted in an article published in January 2018 in Nutrients suggests that zinc may speed up the healing of wounds by lowering inflammation and stimulating immune cells around the site of injury.
Can Adding These Foods to My Diet Help Prevent Illnesses Like the Novel Coronavirus?
However, it appears that if you do test positive for COVID-19, having a zinc deficiency could make your symptoms worse. According to a short study that was published in November 2020 in the International Journal of Infectious Diseases, many COVID-19 patients also had zinc deficiencies, and these individuals experienced more difficulties than those who did not. Nevertheless, additional research is required to determine the precise connection between a zinc shortage and COVID-19.
Unfortunately, it appears that starting to take zinc after a diagnosis will be ineffective. In a trial that was published in February 2021 in JAMA Network Open, zinc supplementation did not help patients who had been diagnosed with COVID-19 have fewer symptoms.
How Much Zinc Should You Take to See Benefits?
According to MedlinePlus, zinc is an essential trace mineral, meaning that our bodies only require a minimal amount of it to stay healthy. The recommended daily limit is 8 milligrams (mg) for adult women and 11 mg for adult men, according to the NIH. Do not undervalue the strength of this powerful mineral, even though only a small quantity may be required.
10 Best Sources of Zinc
Oysters Pack Zinc and Other Key Vitamins and Minerals
The US Department of Agriculture claims that this bivalve is a zinc powerhouse, with each raw oyster containing 5.5 milligrams of zinc. (USDA). Therefore, oysters are a fantastic supply of the element. According to the USDA, this mollusk is also low in calories, containing only 7 calories per oyster, and is rich with numerous essential vitamins and minerals, such as selenium and vitamin B12.
Oysters can be eaten raw, cooked, or on the half shell. You’re going to like them no matter how you serve them, and their zinc content may even help you have a stronger immune system.

Milk and Dairy Foods Help You Meet Your Calcium and Zinc Goals
Milk and yogurt are delightful and nourishing sources of zinc in addition to being rich sources of calcium. The USDA estimates that 1 cup of nonfat milk or low-fat milk provides 1.1 mg and 1.05 mg of the mineral, respectively. In the meanwhile, 1 cup of plain low-fat or nonfat yogurt is a fantastic source, providing 2.38 mg and 2.2 mg, respectively.
When making smoothies, cereal, oatmeal, or yogurt, use low-fat or fat-free milk. You can also try topping yogurt with granola and fresh fruit.
Again, if you cannot consume dairy, do not worry. This list demonstrates that there are several ways to obtain zinc without using animal products.

Try Decadent Dark Chocolate for a Zinc-Filled Dessert
Such a lovely surprise! The fact that dark chocolate contains zinc is yet another intriguing aspect of this treat. And it’s best if it’s darker: According to the USDA, cultivars of cacao that are 60 to 69 percent cacao typically yield some per ounce (almost 0.75 mg), while those that are 70 to 85 percent cacao have a little bit more (0.9 mg).
But that’s not all:Due to its flavanol concentration, dark chocolate may have certain vascular benefits, including decreasing blood pressure and enhancing blood flow, according to the Cleveland Clinic. Remember that there are other sources of zinc besides dark chocolate, even though it may be your favorite. Try to limit your intake to no more than 1 oz each day to control calories and sugar.
WHICH VEGETABLES ARE HIGH IN ZINC?
Eating vegetables has a lot of health benefits, and homegrown food is a great source of zinc and other important vitamins and minerals.
This mineral might be most frequently associated with fighting off colds, but what other functions does it serve in our bodies besides boosting our immune systems, and how can we increase our intake of it through home vegetable gardens?
What You’ll Learn
What Is Zinc?
Mineral, slightly brittle metal, and important nutrient, zinc can be found in nature.
Why does this matter? We must get it from our diets because our bodies cannot generate it and we require it for a number of vital processes.
For healthy adult males aged 19 to 50, the recommended daily limit is 11 milligrams, whereas for healthy adult females it is 8 milligrams. The daily need for pregnant women is 11 milligrams.
How It Functions
Because our bodies cannot store zinc, it’s crucial to get the recommended amount each day. In addition to promoting wound healing, DNA synthesis, protein synthesis, and cell division, it also supports our immune systems.
Additionally, it supports development and growth, particularly during pregnancy, childhood, and adolescence. It also helps to preserve the integrity of our skin and our senses of taste and smell.
At the onset of a cold, some people could use zinc supplements or other items that contain zinc.
If used as soon as symptoms appear, even though its efficacy has not been conclusively demonstrated, it may help shorten and lessen the severity of a cold. Zinc accomplishes this by joining forces with the cold virus prior to its cellular attachment.
Supplements can aid in the treatment of deficiencies or the prevention of colds, but for the average healthy person, food sources are sufficient.
Although fresh vegetables, nuts, seeds, legumes, and even fungi can give large amounts of this mineral, meat, poultry, and shellfish are often the principal sources of zinc in the diets of many people.
For those who eat a vegetarian or vegan diet, these sources are particularly crucial.
Homegrown Sources of Zinc
Whole grains, legumes, certain seeds, fungus, and some vegetables are examples of plant-based supplies.
Phytates are found in grains and legumes. These substances reduce the bioavailability of zinc when coupled with it. This indicates that the body will have a harder time absorbing it.
Fortunately, the majority of garden veggies and mushrooms don’t include phytates, so they’re a good alternative.
In order of highest to lowest amount per serving, these are my favorite locally cultivated sources of zinc:
1. Pumpkin Seeds
2.2 milligrams of zinc, or more than 25% of the daily value for males and 20% for women, are present in one ounce of pumpkin seeds.
More information on the health advantages of pumpkin seeds is available here.
My personal preference when choosing a pumpkin variety to cultivate is the traditional “Jack-O-Lantern.”
‘Jack-O-Lantern’ Pumpkin
It is a great choice for both carving and cooking, and provides plenty of seeds that you can scoop and save for snacking.
Seeds to grow your own are available from Burpee.
And you can learn how to grow pumpkins in our guide.
2. Shiitake Mushrooms
The mineral is present in many different kinds of mushrooms, but the shiitake kind has the highest concentration. One mg of zinc can be obtained from half a cup of cooked, chopped mushrooms.
If you regularly consume mushrooms or want to get your kids interested in eating fungi, growing your own is a good alternative.
Shiitake Mushrooms
Purchasing a starter kit gives you everything you need to get going.

3. Spinach
This leafy green is a nutritional powerhouse and is rich in vitamins and minerals. Cooked spinach has 0.7 milligrams of zinc per half cup.
To get the same mineral payout from raw spinach for a salad or sandwich, you would need a significantly bigger quantity. When spinach is cooked, it greatly condenses.
‘Bloomsdale Long Standing’ Spinach
When choosing a variety to grow in your garden, I like ‘Bloomsdale Long Standing.’ It yields large, dark green leaves that are full of flavor.
Seeds are available in a variety of packet sizes from Eden Brothers.
Don’t forget to read our growing guide for the best spinach harvests!
4. Peas
When I was a child, dinner always included sweet green peas. A half cup contains 0.5 milligrams of the potent mineral, which is a beneficial addition to your daily requirement.
Growing your own peas is often very easy. Try growing these “Garden Sweet” peas if you like a sweeter flavor or perhaps if you live with some picky eaters.
‘Garden Sweet’ Peas
They taste more sugary than other peas, but still contain all of those precious nutrients.
Seeds are available from Burpee.
