Zinc
Zinc is an important nutrient that plays a role in normal body functions. This guide explains what it does, common food sources, what can affect intake, and how tracking your diet can help you understand your overall nutrient intake.
Recommended intake varies by age, sex, and life stage. Tracking what you actually eat can help you understand your overall dietary intake over time.
What Zinc does
Zinc plays a role in:
- supporting immune system function
- helping the body make DNA and proteins
- contributing to normal growth and development
- supporting wound healing and normal taste function
Zinc intake
Intake targets vary across life stages. Age, sex, eating patterns, food variety, and day-to-day routines can all influence how much zinc appears in a person’s diet.
Tracking can help you compare your usual food pattern with the foods that commonly provide zinc.
Common food sources of Zinc
Food sources of Zinc may include:
- oysters and other seafood
- meat and poultry
- eggs and dairy foods
- beans and nuts
- whole grains and fortified breakfast cereals
The amount can vary depending on the food, serving size, preparation method, and brand.
What can affect Zinc intake
A person’s intake may vary due to factors such as:
- food preferences and usual food choices
- restricted diets or low intake of seafood, meat, or whole foods
- appetite changes or small meal sizes
- digestive tolerance and limited food variety
- lifestyle habits and meal routines
Why intake may be lower in some people
Some people may find it harder to get enough Zinc from food alone because of:
- low intake of meat, seafood, eggs, dairy, beans, or whole grains
- limited meal variety over time
- poor tolerance of some common zinc food sources
- changing appetite or eating patterns
Dietary intake can vary a lot from one person to another. This page is about food intake and tracking, not diagnosis or treatment.
Tracking Zinc intake
Tracking your food intake can help you see whether your diet includes regular zinc sources and whether your overall food variety changes over time.
- see whether your diet includes foods that provide Zinc
- spot patterns over time
- identify possible gaps in overall dietary variety
- prepare clearer information for discussion with a healthcare professional
