1. Understanding Protein: The Building Block of Life
Protein, a vital macronutrient, is essential for building and repairing tissues. It plays a crucial role in creating enzymes, hormones, and other essential compounds. Composed of amino acids, protein is the foundation for muscle growth, immune function, and overall well-being. Getting enough protein from your diet is important for optimal health. Protein from food comes from plant and animal sources such as lean meats, poultry, fish, eggs, dairy products, nuts, seeds, legumes and beans.

1.1. Amino Acids: The Components of Protein
Amino acids are the building blocks that make up proteins. About 20 different amino acids link together in different combinations. Your body uses them to make new proteins, such as muscle and bone, and other compounds such as enzymes and hormones. They can also be used as an energy source. Some amino acids can be made by your body – there are 11 of these and they’re known as non-essential amino acids. There are 9 amino acids that your body cannot make, and they are known as essential amino acids. You need to include enough of these in your diet so that your body can function.
1.2. Complete vs. Incomplete Proteins: A Nutritional Perspective
The nutritional value of a protein is measured by the quantity of essential amino acids it contains. Animal products (such as chicken, beef or fish and dairy products) have large amounts of all of the essential amino acids and are known as high-quality protein. Soy products, quinoa and the seed of a leafy green called amaranth (consumed in Asia and the Mediterranean) also have large amounts of all of the essential amino acids. Other plant proteins (beans, lentils, nuts and whole grains) contain all of the essential amino acids, but the amounts of one or two of these amino acids may be low. People following a strict vegetarian or vegan diet need to choose a variety of protein sources from a combination of plant foods every day to make sure they get an adequate mix of essential amino acids. If you follow a vegetarian or vegan diet, as long as you eat a wide variety of foods, you can usually get the protein you need. For example, a meal containing cereals and legumes, such as baked beans on toast, provides all the essential amino acids found in a typical meat dish.
1.3. How Much Protein Do You Need? Factors Influencing Protein Requirements
The amount of protein needed varies depending on several factors, including weight, gender, age, and activity level. Generally, adults need about 0.8 grams of protein per kilogram of body weight per day. Athletes and those engaging in intense physical activity may require more. The daily recommended serves of ‘lean meat and poultry, fish, eggs, tofu, nuts and seeds, and legumes/beans’ and ‘milk, yoghurt, cheese and/or alternatives (mostly reduced fat)’ for adults are shown as below:
| Person | Recommended average daily number of serves of lean meat and poultry, fish, eggs, nuts and seeds, and legumes/beans | Recommended average daily number of serves of milk, yoghurt, cheese and/or alternatives (mostly reduced fat) |
|---|---|---|
| Men aged 19–50 years | 3 | 2 1/2 |
| Men aged 51–70 years | 2 1/2 | 2 1/2 |
| Men aged 70+ years | 2 1/2 | 3 1/2 |
| Women aged 19–50 years | 2 1/2 | 2 1/2 |
| Women aged 51–70 years | 2 | 4 |
| Women aged 70+ years | 2 | 4 |
| Pregnant women | 3 1/2 | 2 1/2 |
| Lactating women | 2 1/2 | 2 1/2 |

6. The Benefits of a High-Protein Diet: More Than Just Muscle
A high-protein diet offers numerous health benefits beyond muscle growth and repair.
6.1. Weight Management
Protein can help you feel fuller for longer, reducing overall calorie intake and aiding in weight loss. Studies have shown that increasing protein intake can boost metabolism and promote fat loss.
6.2. Muscle Growth and Repair
Protein is essential for building and repairing muscle tissue, making it crucial for athletes and those engaging in regular exercise.
6.3. Bone Health
Adequate protein intake is important for maintaining bone density and reducing the risk of osteoporosis, especially as you age.
6.4. Improved Satiety
Protein has a higher satiety value than carbohydrates and fats, helping you feel satisfied and reducing cravings.
6.5. Blood Sugar Control
Protein can help stabilize blood sugar levels, making it beneficial for people with diabetes or insulin resistance.
7. Protein Deficiency: Recognizing the Signs and Symptoms
Protein deficiency means not getting enough protein in your diet. Protein deficiency is rare in Australia, as the Australian diet generally includes far more protein than we actually need. However, protein deficiency may occur in people with special requirements, such as older people and people following strict vegetarian or vegan diets.
7.1. Symptoms of Protein Deficiency
- Wasting and shrinkage of muscle tissue
- Oedema (build-up of fluids, particularly in the feet and ankles)
- Anaemia (the blood’s inability to deliver sufficient oxygen to the cells, usually caused by dietary deficiencies such as lack of iron)
- Slow growth (in children)
7.2. Who is at Risk?
- Older Adults: May have reduced appetite and difficulty absorbing nutrients.
- Vegans and Vegetarians: Need to ensure they consume a variety of plant-based protein sources.
- People with Certain Medical Conditions: Such as malabsorption disorders or kidney disease.
8. Protein and Aging: Maintaining Muscle Mass
From around 50 years of age, humans begin to gradually lose skeletal muscle. This is known as sarcopenia and is common in older people. Loss of muscle mass is worsened by chronic illness, poor diet and inactivity. Meeting the daily recommended protein intake may help you maintain muscle mass and strength. This is important for maintaining your ability to walk and reducing your risk of injury from falls. To maintain muscle mass, it’s important for older people to eat protein ‘effectively’. This means consuming high-quality protein foods, such as lean meats.
9. Protein Supplements: Do You Really Need Them?
Protein shakes, powders and supplements are unnecessary for most Australians’ health needs. According to the most recent national nutrition survey, 99% of Australians get enough protein through the food they eat. Any protein you eat on top of what your body needs will either be excreted from your body as waste, or stored as weight gain. The best way for you to get the protein you need is to eat a wide variety of protein-rich foods as outlined in the Australian dietary guidelines, as part of a balanced diet. But if you are still interested in using protein shakes, powders and supplements, talk to your doctor.
9.1. Types of Protein Supplements
- Whey Protein: A fast-digesting protein derived from milk.
- Casein Protein: A slow-digesting protein derived from milk.
- Soy Protein: A plant-based protein derived from soybeans.
- Pea Protein: A plant-based protein derived from yellow peas.
9.2. When Supplements Might Be Helpful
- Athletes: May need extra protein to support muscle growth and recovery.
- People with Dietary Restrictions: Such as vegans or vegetarians, may use supplements to meet their protein needs.
- Those with Medical Conditions: That affect nutrient absorption.
10. Protein and Exercise: Fueling Your Workouts
Soon after exercising, it’s recommended that you have a serve of high-quality protein (such as a glass of milk or tub of yoghurt) with a carbohydrate meal to help maintain your body’s protein balance. Studies have shown this is good for you, even after low to moderate aerobic exercise (such as walking), particularly for older adults. People who exercise vigorously or are trying to put on muscle mass do not need to consume extra protein. High-protein diets do not lead to increased muscle mass. It’s the stimulation of muscle tissue through exercise, not extra dietary protein, which leads to muscle growth. Studies show that weight-trainers who do not eat extra protein (either in food or protein powders) still gain muscle at the same rate as weight-trainers who supplement their diets with protein.
10.1. Protein Timing
- Pre-Workout: Consuming protein before a workout can help prevent muscle breakdown.
- Post-Workout: Consuming protein after a workout can promote muscle recovery and growth.
10.2. High-Protein Snacks for Exercise
- Protein Bar: A convenient and portable option.
- Greek Yogurt: Provides protein and probiotics.
- Nuts and Seeds: A handful of nuts and seeds offers protein and healthy fats.
11. Debunking Protein Myths: Separating Fact from Fiction
There are several myths surrounding protein consumption that need to be addressed.
11.1. Myth: High-Protein Diets Are Bad for Your Kidneys
Fact: For healthy individuals with normal kidney function, a high-protein diet is not harmful. However, those with pre-existing kidney conditions should consult a healthcare professional.
11.2. Myth: You Need to Eat Protein Immediately After a Workout
Fact: While consuming protein after a workout is beneficial, the timing is not as critical as once thought. Aim to consume protein within a few hours of your workout.
11.3. Myth: You Need to Eat a Lot of Meat to Get Enough Protein
Fact: There are plenty of plant-based protein sources that can provide all the essential amino acids you need.
11.4. Very High Protein Diets are Dangerous
Some fad diets promote very high protein intakes of between 200 and 400 g per day. This is more than 5 times the amount recommended in the Australian dietary guidelines. The protein recommendations in the guidelines provide enough protein to build and repair muscles, even for body builders and athletes. A very high-protein diet can strain the kidneys and liver. It can also prompt excessive loss of the mineral calcium, which can increase your risk of osteoporosis.
