Iron
Iron 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 Iron does
Iron plays a role in:
- making hemoglobin, which carries oxygen in red blood cells
- supporting myoglobin, which helps move oxygen into muscles
- contributing to normal oxygen transport around the body
- supporting the production of some hormones
Iron intake
Intake targets vary across life stages. Age, sex, eating patterns, food variety, and day-to-day routines can all influence how much iron appears in a person’s diet.
Tracking can help you compare your usual food pattern with the foods that commonly provide iron.
Common food sources of Iron
Food sources of Iron may include:
- lean red meat
- seafood
- poultry
- beans and lentils
- iron-fortified breakfast cereals and breads
The amount can vary depending on the food, serving size, preparation method, and brand.
What can affect Iron intake
A person’s intake may vary due to factors such as:
- food preferences and usual food choices
- restricted or low-variety diets
- appetite changes or small meal sizes
- digestive tolerance that limits foods such as meat, legumes, or cereals
- lifestyle habits and meal routines
Why intake may be lower in some people
Some people may find it harder to get enough Iron from food alone because of:
- low intake of meat, seafood, fortified grains, or legumes
- limited meal variety over time
- poor tolerance of some common iron-containing foods
- 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 Iron intake
Tracking your food intake can help you see whether your diet regularly includes foods that provide iron and whether your overall dietary pattern changes over time.
- see whether your diet includes foods that provide Iron
- spot patterns over time
- identify possible gaps in overall dietary variety
- prepare clearer information for discussion with a healthcare professional
