The Top 30 Foods High In Zinc

Last updated: August 25, 2023 Michael Joseph, MSc, ANutr

Zinc is an essential mineral with several important functions in the body.

However, where can we find the best dietary sources of the mineral?

This article presents thirty foods high in zinc from diverse food groups.

Why is Zinc Important?

Various foods high in zinc in a pile next to each other.

Zinc is a micronutrient that we need to obtain from the food we eat. Thus, it is classed as an ‘essential mineral.’

Among its functions, zinc plays a vital role in the immune system, DNA production, growth, and wound healing (1).

Zinc deficiency is relatively prevalent globally, particularly in developing countries. Based on data from 2012, it is estimated that approximately 17% of people globally have zinc deficiency (2).

High levels of zinc are present in foods such as meat, fish, shellfish, legumes, and whole grains.

How Much Zinc Do We Need?

Recommended Dietary Allowance (RDA)

The Food and Nutrition Board at the National Academies of Sciences, Engineering, and Medicine has set a recommended dietary allowance (RDA) for zinc. These RDA values vary depending on age and sex and are as follows (3):

Age Group and Life Stage	Male	Female
<6 months old (Adequate Intake*)	2 mg	2 mg
7-12 months	3 mg	3 mg
1-3 years	3 mg	3 mg
4-8 years	5 mg	5 mg
9-13 years	8 mg	8 mg
14-18 years	11 mg	9 mg
>19 years old	11 mg	8 mg
During pregnancy (age <18 years)		12 mg
During pregnancy (age >19 years)		11 mg
Lactation (<18 years)		13 mg
Lactation (>19 years)		12 mg

^{Table 1: Recommended dietary allowances (RDAs) for zinc intake by age and group}

*An adequate Intake (AI) is set when there is insufficient data to make an evidence-based RDA recommendation. However, the AI is assumed to provide an adequate amount of zinc.

Daily Values (% DV)

The US Food and Drug Administration (FDA) has also set a simple reference value for the amount of zinc that we should consume. This is known as a ‘daily value’ (% DV), and it is based upon a typical 2000-calorie diet.

The daily value for zinc is 11 mg (4).

Foods High In Zinc

The following list of zinc-rich foods shows how much of the mineral each food offers per 100 grams and per typical serving.

For each food, you can find the amount of zinc it contains per typical serving and per 100 grams.

The source of all nutritional data is the USDA FoodData Central database.

Listed daily values have been calculated using USDA data alongside the FDA’s published daily values.
