Introduction
Protein is one of the most talked-about nutrients in nutrition.
From protein shakes and protein bars to high-protein diets, it’s easy to get the impression that everyone needs to eat as much protein as possible. At the same time, some people believe protein is only important for bodybuilders or athletes.
In reality, protein is an essential nutrient that everyone needs.
Protein supports many important functions throughout the body, including maintaining muscles, repairing tissues, producing hormones and enzymes, and supporting a healthy immune system. Whether you’re physically active or not, your body relies on protein every day to function properly.
Like carbohydrates and healthy fats, protein is one of the three macronutrients that make up a balanced diet. Rather than focusing on eating excessive amounts, the goal is to consume enough protein as part of a varied and nutritious eating pattern.
At 1% Movement, we believe healthy eating should be practical and evidence-based. Understanding the role of protein can help you make informed food choices without falling for nutrition myths or marketing claims.
In this article, you’ll learn what protein is, why it matters and how to include it in a healthy eating pattern.
What Is Protein?
Protein is one of the three macronutrients your body needs in relatively large amounts.
Proteins are made up of smaller building blocks called amino acids, which are used throughout the body to build, repair and maintain tissues.
Unlike carbohydrates, which primarily provide energy, protein’s main role is to support the structure and function of the body’s cells and tissues.
Your body uses protein to:
- Build and maintain muscle.
- Repair body tissues.
- Produce enzymes.
- Produce hormones.
- Support immune function.
- Maintain healthy skin, hair and nails.
- Support normal growth and development.
Because the body is constantly repairing and replacing tissues, protein needs to be consumed regularly through food.
Why Protein Matters
Protein contributes to many important aspects of health.
It helps:
- Maintain muscle mass.
- Support recovery after physical activity.
- Promote normal growth and tissue repair.
- Produce antibodies that support immune function.
- Support healthy bones alongside regular physical activity and adequate nutrition.
- Contribute to feelings of fullness after meals.
Protein is important throughout every stage of life—from childhood and adolescence to older adulthood.
For people who are becoming more active, including those following our Beginner Movement & Strength or Walking & Cardiovascular Health programmes, consuming adequate protein alongside regular exercise helps support normal muscle maintenance and recovery.
Sources of Protein
Protein comes from both animal and plant foods.
Animal Protein Sources
Examples include:
- Fish
- Chicken
- Turkey
- Lean beef
- Eggs
- Milk
- Yoghurt
- Cheese
These foods generally provide high-quality protein together with several important vitamins and minerals.
Plant Protein Sources
Many plant foods also provide protein.
Examples include:
- Beans
- Lentils
- Chickpeas
- Tofu
- Tempeh
- Edamame
- Nuts
- Seeds
Including a variety of plant protein foods can contribute to a balanced eating pattern while also providing fibre and other beneficial nutrients.
For most people, both animal and plant protein foods can fit within a healthy diet depending on personal preferences, cultural practices and dietary choices.
Protein and Physical Activity
Protein is often associated with athletes and strength training, but it is important for everyone.
For people who participate in resistance training, walking or other forms of regular physical activity, protein supports the normal repair and maintenance of muscles after exercise.
However, exercise and protein work together.
Eating large amounts of protein without being physically active does not automatically build muscle.
Likewise, exercise without consuming enough protein may make it more difficult to support normal muscle maintenance over time.
Combining regular movement with balanced nutrition is one of the principles of Lifestyle Medicine and forms an important part of long-term health.
How Much Protein Do You Need?
Protein needs vary from person to person.
There is no single amount that is ideal for everyone because requirements are influenced by several factors, including:
- Age
- Body size
- Physical activity level
- Overall health
- Life stage (such as pregnancy or older adulthood)
For example, someone who regularly participates in strength training or endurance exercise may have higher protein needs than someone with a more sedentary lifestyle.
Most healthy adults can meet their protein requirements through a balanced diet that includes a variety of protein-rich foods throughout the day.
Rather than focusing on eating as much protein as possible, aim to include a source of protein with most meals as part of a balanced eating pattern.
Do You Need Protein Supplements?
Not necessarily.
Many people meet their protein needs through everyday foods such as:
- Fish
- Poultry
- Eggs
- Dairy products
- Beans
- Lentils
- Tofu
- Tempeh
- Nuts
- Seeds
Protein powders and ready-to-drink shakes can be convenient in certain situations, particularly for people with higher protein requirements or limited time to prepare meals.
However, supplements should not replace a balanced diet built around whole foods.
For most people, food should remain the primary source of protein whenever possible.
Can You Eat Too Much Protein?
Like any nutrient, protein should be consumed as part of a balanced diet.
Eating very large amounts of protein does not automatically improve muscle growth, athletic performance or overall health.
Instead of focusing on one nutrient alone, it’s more helpful to build meals that include:
- Protein
- Healthy carbohydrates
- Healthy fats
- Plenty of vegetables and fruit
This balanced approach provides a wider range of nutrients that work together to support overall health.
Building Balanced Meals with Protein
Including protein at meals can help create satisfying, balanced eating patterns.
Examples include:
Breakfast
- Greek yoghurt with fruit and oats
- Eggs with wholegrain toast
- Overnight oats made with milk and nuts
Lunch
- Grilled chicken salad
- Lentil soup with wholegrain bread
- Tuna sandwich with salad
Dinner
- Baked salmon with brown rice and vegetables
- Tofu stir-fry with wholegrain noodles
- Bean chilli served with rice
Combining protein with vegetables, whole grains and healthy fats creates meals that provide a wide range of nutrients while supporting overall health.

Common Protein Myths
Nutrition misinformation has led to many misconceptions about protein.
Let’s look at a few common myths.
Myth 1: Protein is only important for athletes.
No.
Everyone needs protein to support normal growth, tissue repair, immune function and overall health.
Myth 2: More protein always means more muscle.
No.
Building muscle depends on a combination of regular resistance exercise, adequate nutrition and sufficient recovery.
Eating excessive amounts of protein alone will not automatically increase muscle mass.
Myth 3: Plant proteins are inferior.
Not necessarily.
Many plant foods provide excellent sources of protein and can contribute to a balanced diet.
Eating a variety of plant protein sources helps provide a broad range of nutrients while supporting overall health.
Myth 4: You need protein supplements to be healthy.
No.
Most people can meet their protein needs through everyday foods without requiring supplements.
Protein powders may be convenient for some individuals but are not essential for good health.
