Top 10 Paleo Foods that Contain Zinc

Zinc is an essential trace mineral that is needed for health.

Over 300 of the body’s enzymes require zinc to function and carry out reactions.

Zinc is not readily stored in the body, so the diet must supply adequate levels of this mineral.

There are also certain populations who are more at risk for zinc deficiencies.

Without enough zinc in your diet, the body cannot grow, develop or function.

Check out our list of top 10 Paleo foods that are rich in zinc. Be sure to give our zinc recipes a try, as well.

What is zinc?

Zinc is a trace mineral. Trace minerals, or microminerals, are ones that we need less than 100 mg of every day.

In contrast to other minerals like iron, zinc does not have any specific storage sites in the body. There is only a small, exchangeable amount of zinc found in the bone, liver and blood. If this minimal zinc pool is not replaced, then a zinc deficiency can result.

Zinc is needed to assist in enzymatic reactions, regulate genes, boost immunity, and aid in growth and sexual maturation. Additionally, zinc also supports antioxidant function, which protects the body from harmful invaders and lowers chronic disease risk.

Meat, fish and poultry are the best dietary sources of zinc because they are the most absorbable forms. Phytates found in vegetables, fruits or grains actually inhibit the absorption of zinc rendering them as insufficient sources.

What are the health benefits of zinc?

  • Boosts immune function
  • Fights off illness and infection
  • Needed for wound healing
  • Lowers inflammation
  • Helps with normal growth and development
  • Increases antioxidant function

Why is it good for the heart?

  • Zinc is an antioxidant that helps to fight off oxidative stress and inflammation
  • Zinc is needed to support healthy cardiac cells1
  • Adequate intracellular zinc is needed for normal nitric oxide levels and blood pressure regulation2
  • It has also been shown to reduce LDL cholesterol and triglycerides3
  • Increased intracellular levels of zinc are protective and are associated with a decreased risk of cellular damage following heart attack or ischemia1

How much zinc do we need?

The RDA’s for adults is 8 mg of zinc for females and 11 mg of zinc for males per day.

Who is most at risk for low zinc levels?

Pregnancy and lactation status increases zinc needs. Infants, children and adolescents are also at risk for zinc deficiency and thus need more.

Additionally, zinc absorption can be inhibited by non-heme iron food sources (i.e. plant based iron).

Signs of low zinc levels include increased illness and infection, hair loss, skin lesions, growth retardation.

Should I supplement?

If you don’t get enough zinc in your diet due to a lack of meat/ shellfish consumption or are pregnant or lactating, you may need to supplement.

Try our Zinc supplement for immediate support. 1 capsule provides a bioavailable 25 mg serving of zinc.

Another great option would be to try our Multi Vitamin with exceptional amounts of zinc and other nutrients for health. 4 capsules of our multi provide 25 mg zinc!
