What is Zinc?
Zinc is an essential trace mineral that plays a role in more than a hundred enzymatic reactions in the body, which is why consuming foods high in zinc is so important. Some include: playing a vital role in immune system response, wound healing, synthesizing proteins and DNA, and many other bodily functions.
You need this mineral in small amounts every day to maintain your health and perform important functions. Zinc benefits come from its presence within all bodily tissue — it’s needed for healthy cell division, and it acts like an antioxidant, fighting free radical damage and slowing the aging process.
Do you know that zinc deficiency is a major malnutrition problem worldwide, and inadequate intake of foods high in zinc is one of the chief causes. According to the World Health Organization, millions of people throughout the world may have inadequate levels of zinc in their diets. In fact, zinc deficiency is ranked the fifth-leading risk factor in causing disease worldwide. It occurs when you don’t have enough foods containing zinc in your diet, or you have trouble absorbing zinc from foods because of digestive disorders or very poor gut health.
The good news is that if people consume enough foods high in zinc, like the top fifteen sources listed below, they can prevent inadequate zinc levels and reap the benefits of this essential mineral.
Top 15 Foods High in Zinc
Animal foods are the best sources of zinc compared to plant foods, like vegetables, because zinc bioavailability (the fraction of zinc that’s retained and used by the body) is high in foods like animal meat and seafood.
Although there are plant-based zinc foods, they’re less bioavailable because of their high content of phytic acid (or phytates), which inhibits zinc absorption. Reports suggest that people who don’t eat meat or animal products, like people on a vegetarian or vegan diet, need up to 50 percent more zinc in their diets to absorb what the body needs.
However, the inhibitory effects of phytic acid on the absorption of zinc can be minimized with methods like soaking, heating, sprouting, fermenting and leavening. Research also shows that the absorption of zinc can be improved by using yeast-based breads and sourdough breads, sprouts, and pre-soaked legumes.
The best way to achieve optimal zinc levels is to consume two to three servings of these zinc foods per day:
3 ounces: 6.7 milligrams (45 percent DV)
Lamb is a rich source of many vitamins minerals. In addition to zinc, lamb contains vitamin B12, riboflavin, selenium, niacin, phosphorus and iron.

5. Chickpeas (Garbanzo Beans)
1 cup: 2.5 milligrams (17 percent DV)
Chickpeas, like all legumes, are complex carbohydrates that the body can slowly digest and use for energy. Studies show that chickpeas increase satiety and help with weight loss. They also improve digestion by flashing foods through the digestive tract.
1 cup: 2.5 milligrams (17 percent DV)
We know lentils for their health-promoting effects, as they are rich in polyphenols and micronutrients, including zinc. Lentils serve as a plant-based protein, making them an excellent zinc-rich food for vegetarians.
7. Cocoa Powder
1 ounce: 1.9 milligrams (13 percent DV)
Cocoa powder is a superb source of two flavonoids, epicatechin, and catechin, which function as antioxidants that help prevent inflammation and disease. Because of the presence of flavonoids in cocoa powder, it helps improveblood flow and lower blood pressure, too.
1 ounce: 1.6 milligrams (11 percent DV)
Cashews are rich in unsaturated fatty acids and high in protein. Cashews nutrition helps fight heart disease, reduce inflammation, promote bone health and support healthy brain function. These nuts help with weight loss or maintenance because they make you feel fuller and curb food cravings. Plus, cashews have good zinc to copper ratio, to help ensure that both of these minerals stay in balance.

Proven mushroom nutrition benefits include the ability to boost immunity due to its antioxidant activities, reduce inflammation, fight cancer, protect your heart and improve brain function.
1 cup: 1.4 milligrams (9 percent DV)
Spinach is one of the most nutrient-dense foods in existence. It contains special protective carotenoids that we believe to decrease the risk of many diseases, including heart disease, obesity, diabetes, neurodegenerative diseases and even cancer.
1 avocado: 1.3 milligrams: (8 percent DV)
If you’re looking for fruits that contain zinc, reach for an avocado. It’s known as one of the healthiest foods on the planet because it’s packed with essential nutrients. And research shows that avocado consumption is associated with better diet quality and nutrient intake.
100 grams: 1 milligram (7 percent DV)
In addition to the zinc present in chicken, it’s also a good source of B vitamins, including vitamin B12, niacin, vitamin B6 and pantothenic acid. The vitamin B12 in chicken helps maintain energy levels, boost mood, maintain heart health and boost skin health.

Top Health Benefits of Zinc and Foods High in Zinc
Consuming food sources of zinc regularly will help to improve your health in the following ways:
- Works as a powerful antioxidant: Zinc helps to fight oxidative stress and decrease your chances of developing several serious diseases, including cancer. The research found that zinc supplementation significantly lowered infection rates in participants ages 55 to 87 years.
- Boosts eye health: we need Zinc to convert vitamin A into its active form to maintain proper vision. Adequate intake of foods high in zinc can help improve night vision and symptoms of age-related macular degeneration, a leading cause of blindness. This is because of zinc’s ability to reduce oxidation and inflammation, which are associated with diminished eye health.
- Enhances immune function: The body needs zinc to activate T-cells, which are critical for proper immune function, and that is why people deficient in zinc tend to more susceptible to a variety of illnesses, including the common cold.
- Promotes wound healing: Zinc benefits the integrity of the skin and helps treat infections. Research shows that people who have delayed wound healing tend to have low levels of zinc.
- Balances hormones and supports reproductive health: Zinc plays an important role in hormone production. It’s needed for the production of estrogen and progesterone in women, and it increases testosterone levels and sperm quality naturally. Zinc is also needed to balance insulin, the main hormone involved in the regulation of normal blood sugar.
- Promotes muscle growth and repair: Zinc plays a crucial role in cell division and cell growth, so it’s needed to maintain strength in the muscular and skeletal systems. Zinc also helps with the release of testosterone, growth hormone and insulin-like growth factor-1, all of which build muscle mass and helps you maintain a healthy metabolism.
- Aids in nutrient absorption: Zinc affects protein synthesis and is needed by the body to use amino acids from food. It’s also involved in the breakdown of carbohydrates from foods, which are some main sources of energy from the body. Therefore, a zinc deficiency can lead to low energy levels and contribute to adrenal or chronic fatigue.
- Promotes heart health: we need Zinc to maintain the health of cells within the cardiovascular system, while also lowering inflammation and oxidative stress.
