The Importance of Protein

Table of contents

Eating enough protein is not just important for bodybuilders. Despite its popularity within the fitness world, protein is a major component of health and ensuring you get enough protein is essential.

What is protein?

Protein is an essential macronutrient found in every cell of the body, including muscle, bone, skin, and hair. Proteins are made up of long chains of amino acids, basic building blocks composed of nitrogen, carbon, hydrogen, and oxygen. There are 20 amino acids that make up the proteins in the human body; 11 which the body can make, and 9 which are considered essential and must be consumed through the diet.¹ Your body contains at least 10,000 different proteins which play an essential role in muscle growth and maintenance, energy production, cartilage structure, hormone regulation, and enzyme production.¹

Proteins are obtained from dietary sources, and the amount of protein you require is influenced by several factors: age, gender, activity levels, pregnancy, and special dietary requirements.


As we age, the body starts to process protein less efficiently which can lead to loss of skeletal muscle mass and an increased risk of falls, functional decline, and frailty.² Increasing your protein intake as you age is essential to preserve muscle mass, protect bone health and support your immune system,³⁻⁴ and spreading your protein intake throughout the day is thought to support muscle synthesis.⁵

Protein is also an essential nutrient for growing kids, as it provides the basics for building and repairing muscles, providing energy, and supporting strong bones.⁶ Many sources of protein also provide important nutrients like vitamin E, B, zinc, iron, and magnesium, which also have roles in essential functions all over the body.⁶

Generally, individuals with more muscle mass, higher recommended calorie intake, and larger bodies need more protein each day. However, both weight and activity level play an important role in protein requirements.⁷ Recommended protein intake depends on your training level and end goals, so a male and female of a similar size and weight who are both strength training towards similar goals would have similar recommended protein intakes.

If you train regularly, you should be aiming for 1-2g of protein per kg body weight, and this needs to be adjusted depending on the type of exercise, intensity, and frequency. If you don’t train, your recommended intake may be closer to 0.8-1g per kg.⁷


Adequate protein intake during pregnancy is essential to provide the building blocks for the baby’s cells and organs, and the development of skin, hair, fingernails, muscles, and bones.⁸ Protein also supports breast and uterine tissue growth, and plays a role in increasing the blood supply and ensuring adequate blood is supplied to the baby.⁸
Protein intake is especially critical during the second and third trimesters (week 13+), when the baby and mother are growing the fastest.⁹

Vegetarian and vegan diets

A common concern about vegetarian or vegan diets is that they may lack sufficient protein, and a poorly planned meat-free diet may leave you lacking in certain nutrients.¹⁰ However, many plant-based foods are great sources of protein and also provide great levels of essential vitamins and minerals.

When following a vegetarian or vegan diet, it’s important to eat protein from a variety of sources to ensure you consume adequate amounts of the essential amino acids.¹¹ Complementary food combinations are a great way to ensure you obtain all the essential amino acids, and great combinations which provide a complete amino acid profile include: whole wheat toast and nut butter, wholegrain pitta and hummus, beans and rice, oatmeal with peanut butter, and spinach salad with sunflower seeds.

For more information on adequate protein intake for a vegetarian or vegan diet, visit the Vegan Society.
