Protein
Protein 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 Protein does
Protein plays a role in:
- building and maintaining bones, muscles, and skin
- supporting growth and tissue repair
- contributing to the production of enzymes and hormones
- providing energy when needed
Protein intake
Intake targets vary across life stages. Age, sex, eating patterns, food variety, and day-to-day routines can all influence how much protein appears in a person’s diet.
Tracking can help you compare your usual food pattern with the foods that commonly provide protein.
Common food sources of Protein
Food sources of Protein may include:
- meat and poultry
- fish and seafood
- eggs and dairy foods
- beans, lentils, and soy foods
- nuts, seeds, and some grains
The amount can vary depending on the food, serving size, preparation method, and brand.
What can affect Protein intake
A person’s intake may vary due to factors such as:
- food preferences and usual food choices
- restricted diets or low intake of protein-rich 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 Protein from food alone because of:
- low intake of meat, fish, eggs, dairy, legumes, soy foods, or nuts
- limited meal variety over time
- poor tolerance of some common protein 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 your food intake can help you see whether your diet regularly includes protein-rich foods from animal or plant sources and whether your intake pattern changes over time.
- see whether your diet includes foods that provide Protein
- spot patterns over time
- identify possible gaps in overall dietary variety
- prepare clearer information for discussion with a healthcare professional
