Foods high in zinc - Dr. Axe

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.

This mineral (along with iron) is needed in small amounts every day in order 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. 

Zinc deficiency is now known to be a major malnutrition problem worldwide, and inadequate intake of zinc is one of the main 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 sources of zinc in your diet, or you have trouble absorbing zinc due to digestive disorders or very poor gut integrity. 

The good news is that if people consume good sources of zinc daily, like the top 17 sources listed below, they can prevent inadequate levels and reap the benefits of this essential mineral. 

Top 17 Foods High in Zinc

Animal products 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.

Research shows that this is due to the absence of compounds that inhibit zinc absorption in animal sources and the presence of sulfur-containing amino acids that improve zinc absorption, like cysteine and methionine.

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 daily to absorb what they need.

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 presoaked legumes.

The best way to achieve optimal zinc levels is to consume two to three servings of these zinc foods per day:

1. Oysters

3 medium-sized oysters: 16 milligrams (145 percent DV)

6. Chickpeas (Garbanzo Beans)

Benefits

Consuming good sources of zinc regularly is beneficial in the following ways:

  • Works as a powerful antioxidant: Zinc helps fight oxidative stress and decrease your chances of developing a number of serious diseases. In fact, zinc supplementation significantly lowered infection rates in participants ages 55 to 87 years in a randomized, controlled trial.
  • Boosts eye health: Zinc is needed to covert vitamin A into its active form in order to maintain proper vision. Adequate sources of zinc can help improve night vision and more. This is due to zinc’s ability to reduce oxidation and inflammation, which are associated with diminished eye function.
  • Enhances immune function: Studies have shown that humans needs zinc to activate T-cells, which are critical for proper immune function. That is why people who are deficient in zinc tend to more susceptible to a variety of illnesses from a weakened immune system, 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 reproduction: Zinc plays an important role in hormone production. It’s needed for the production of estrogen and progesterone in women, and it has shown to to increase 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: Studies have found that zinc plays a crucial role in cell division and cell growth, so it’s needed to maintain strength in the muscular and skeletal systems. Eating good sources of zinc daily also helps with the release of testosterone, growth hormone and insulin-like growth factor-1, all of which build muscle mass and help you maintain a healthy metabolism.
  • Aids in nutrient absorption: Zinc affects protein synthesis and is needed to use amino acids from food. It’s also involved in the breakdown of carbohydrates, which are some of the main sources of energy for humans. This is why a zinc deficiency can lead to low energy levels and contribute to adrenal or chronic fatigue.
  • Promotes cardiovascular function: Research has proven that zinc is needed to maintain the health of cells within the cardiovascular system, while also lowering inflammation and oxidative stress.
