Protein is an essential macronutrient that provides structure and support to cells and protects the body from viruses and bacteria. It is found in all body parts, from our hair to our bones. A protein-deficient diet can have several negative effects on the body and its functions. While true protein deficiency is uncommon in the Western world, some people may experience low protein levels due to various factors such as malnutrition, pregnancy, eating disorders, liver disorders, kidney problems, and inflammatory bowel diseases. The effects of protein deficiency can range from hair and skin changes to more severe issues such as a weak immune system, muscle loss, and stunted growth.

Protein deficiency can cause hair and skin issues
Protein is an essential macronutrient that provides structure and support to cells and protects the body from viruses and bacteria. It is found everywhere in the body, including the muscles, skin, hair, bones, and blood. While true protein deficiency is uncommon in the Western world, some people get very low amounts from their diets, which can affect almost all aspects of body function and lead to various health problems.
Additionally, protein is needed to produce collagen, which is found in connective tissues and the skin. A lack of collagen can cause cuts, scrapes, and sprains to take longer to heal. It can also affect the skin's elasticity and contribute to wrinkles and premature aging.
A protein-rich diet can help prevent and address these hair and skin issues. Good sources of protein include fatty fish, lean meats, eggs, lentils, legumes, nuts, and low-fat dairy. However, it is important to maintain a balanced diet and not overdo protein intake, as too much protein can also cause problems.

It can lead to swelling, also known as edema
Protein deficiency can cause swelling, also known as edema. Edema is a condition characterised by swollen and puffy skin. It is a symptom of severe protein deficiency, which is unlikely to occur in developed countries. However, it is a common problem in developing countries where malnutrition is prevalent.
The body needs protein to produce albumin, a type of protein that circulates in the blood and helps keep fluid from building up in the tissues. When there is not enough protein in the diet, the body cannot make enough albumin, which leads to reduced oncotic pressure. Oncotic pressure is a force that draws fluid into the blood circulation. With low oncotic pressure, fluid accumulates in the tissues, causing swelling.
Edema typically occurs in the abdomen, legs, feet, and hands. It is also associated with kwashiorkor, a severe form of protein deficiency that often affects children in developing countries. Kwashiorkor is characterised by edema in the arms and legs due to low protein levels in the blood.
While protein deficiency is uncommon in Western countries, certain groups are at higher risk, such as older adults, especially those in long-term care facilities or receiving home-delivered meals. Additionally, individuals with malnutrition, pregnancy, eating disorders, liver disorders, kidney problems, or inflammatory bowel diseases may be more susceptible to protein deficiency and edema.
If you experience swelling or other symptoms of protein deficiency, it is important to consult a healthcare professional or registered dietitian for personalised advice and guidance.

It negatively impacts the immune system
Protein deficiency can negatively impact the immune system in several ways. Firstly, proteins are essential for the production of antibodies, which are required to fight off infections. Antibodies are produced by white blood cells, and a protein deficit can hinder this process, making it more difficult for the body to defend itself against pathogens.
Secondly, amino acids, which are the building blocks of proteins, play a crucial role in maintaining a healthy immune system. They are necessary for the proper functioning of neurotransmitters, which regulate mood and influence how the brain works. A lack of protein can result in low levels of neurotransmitters like dopamine and serotonin, potentially leading to mood changes, depression, or aggressive behaviour.
Additionally, protein deficiency can lead to muscle wasting, particularly in older adults. This is because the body tends to take protein from skeletal muscles when there is a shortage of dietary protein. As a result, individuals may experience muscle weakness and an overall decrease in strength, impacting their ability to fight off infections and maintain a strong immune response.
Moreover, protein deficiency can cause oedema, or swelling, especially in the abdomen, legs, feet, and hands. This is due to low levels of albumin, a protein that helps maintain oncotic pressure and prevents fluid buildup in tissues. Oedema can further compromise the immune system by affecting the body's ability to fight off infections and heal wounds effectively.
Finally, a protein-deficient diet often coincides with an overall poor diet and malnutrition. This can lead to deficiencies in other essential nutrients that are critical for immune function, such as vitamins A, C, D, E, B12, and minerals like zinc, selenium, copper, and iron. These nutrients work together with proteins to ensure a properly functioning immune system. Therefore, a lack of protein can have a cascading effect, impairing the absorption or activity of other nutrients and ultimately compromising the body's defence mechanisms.

It can cause weight gain
Protein is an essential building block of the body's system, and a deficiency can lead to various health problems. While true protein deficiency is uncommon in the Western world, some people do not get sufficient protein from their diets. A lack of protein can affect almost all aspects of body function.
Protein plays a key role in appetite maintenance and total calorie intake. If you are not consuming enough protein, your body will attempt to restore your protein status by increasing your appetite and encouraging you to eat. This may lead to the consumption of foods high in carbohydrates and fats to compensate for the lack of protein. However, foods high in carbohydrates and fats are not as satiating as high-protein foods. Over time, this may lead to the consumption of too many calories, resulting in unintended weight gain and obesity.
Research has shown that a diet high in protein keeps hunger at bay for longer compared to a meal consisting mostly of carbohydrates. A study published in the *American Journal of Clinical Nutrition* found that women who increased their protein intake to 30% of their total calories ended up eating 441 fewer calories per day. As a result, they lost an average of 11 pounds in just 12 weeks. Another study of 158 people conducted in 2008 found that ingesting whey protein helped increase fat burning while preventing muscle loss.
The amount of protein you need to consume per day depends on several factors, such as your age, level of physical activity, and fitness goals. Current guidelines recommend that adults aged 19 and older consume 10 to 35% of their daily calories from protein. This equates to about 200 to 700 calories from protein for a 2,000-calorie diet. Another way to calculate your daily protein requirement is to multiply 0.8 grams of protein per kilogram of your body weight. For example, this translates to 54 grams of protein for a 150-pound woman or 65 grams for a 180-pound man.

It can lead to muscle loss and weak bones
Protein is an essential macronutrient that provides structure and support to cells and protects the body from viruses and bacteria. It exists in every body part, from the hair to the bones. A protein-rich diet is particularly important for children, adolescents, and pregnant individuals, as it is critical for growth and development.
Protein deficiency is uncommon in Western countries, but it can present a wide range of symptoms. It can affect almost all aspects of body function and lead to various health problems. The body's largest reservoir of protein is in the muscles. When dietary protein is insufficient, the body takes protein from skeletal muscles to preserve more vital tissues and functions. This can lead to muscle wasting, reduced muscle mass, and muscle weakness. Research suggests that older adults are particularly susceptible to muscle loss due to protein deficiency. A study found that adults aged 65 and older who consumed more protein were less likely to experience bone fractures.
Additionally, protein is essential for bone health. A lack of protein can lead to weak bones and an increased risk of stress fractures. This is because bone tissue needs protein to maintain its strength and integrity.
If you suspect you are not getting enough protein, it is important to consult a healthcare professional or a registered dietitian. They can provide guidance and advice on how to increase your protein intake and improve your overall nutritional status.
