In the pursuit of a healthy lifestyle, the importance of macronutrients like protein cannot be overstated. However, recent warnings from experts shed light on the potential life-threatening consequences of consuming too much protein. From protein poisoning symptoms to long-term health risks, understanding the dangers is crucial.
PROTEIN POISONING: A HIDDEN THREAT
While proteins are essential for optimal body functioning, an excess of this macronutrient can lead to protein poisoning, a condition with severe consequences. Also known as rabbit starvation or mal de caribou, protein poisoning occurs when there’s an imbalance in the intake of proteins, fats, and carbohydrates over an extended period.
SYMPTOMS OF PROTEIN POISONING
Identifying the symptoms of protein poisoning is crucial for prompt intervention. Common signs include nausea, headaches, mood swings, weakness, constant fatigue, low blood pressure, insatiable hunger, recurrent diarrhoea, slow heart rate, and body cramps.
THE ROLE OF LIVER AND KIDNEYS
Excessive intake poses a risk to vital organs like the liver and kidneys, which play key roles in protein metabolism. Studies indicate that prolonged high protein consumption can elevate levels of ammonia, urea, and amino acids in the blood, potentially leading to organ damage.
RECOMMENDED DIETARY ALLOWANCE (RDA): STRIKING A BALANCE
To maintain a healthy intake, adhering to the Recommended Dietary Allowance (RDA) is essential. Adults generally need 0.8 grams per kilogram of body weight per day. However, individual requirements vary based on factors like activity levels, age, size, and weight.
RISKS OF EXCESSIVE INTAKE
Overindulging in proteins for an extended period carries significant risks, including kidney damage due to excessive nitrogen, heightened cancer risk (particularly breast and prostate cancer), and increased susceptibility to heart diseases, including high blood pressure.
DEHYDRATION DANGERS
Another consequence of excessive proteins intake is dehydration. The body expels fluids, potentially leaving individuals dehydrated despite not feeling unusually thirsty. To mitigate this risk, increasing water intake, especially for those with active lifestyles, is crucial.
TREATMENT AND PREVENTION
Addressing protein poisoning involves creating a balanced diet that considers not only proteins but also healthy fats and carbohydrates. Reducing intake to a maximum of 2.0 grams per kilogram of body weight, along with incorporating adequate fibre, promotes overall well-being and helps restore proteins levels to normal.
In the pursuit of a healthy lifestyle, awareness of the potential pitfalls of excessive intake is paramount. Striking a balance and embracing a well-rounded diet is the key to ensuring optimal health and mitigating the risks associated with proteins overconsumption.

TYPES OF PROTEINS
- Antibodies: Play a crucial role in the immune system, recognizing and neutralizing foreign substances.
- Contractile Proteins: Enable muscle contraction and movement.
- Enzymes: Catalyze biochemical reactions in the body, facilitating metabolic processes.
- Hormonal Proteins: Act as messengers, regulating physiological processes and communication between cells.
- Structural Proteins: Provide support and strength to cells and tissues.
- Storage Proteins: Store essential molecules or ions for future use.
- Transport Proteins: Facilitate the movement of substances across cell membranes or within the bloodstream.
TYPES OF PROTEINS BASED ON TERTIARY STRUCTURE
- Globular Proteins: Exhibit a compact, spherical shape; often involved in metabolic processes.
- Fibrous Proteins: Form long, thread-like structures; contribute to the structural integrity of cells and tissues.
- Membrane Proteins: Integral components of cell membranes, playing roles in transport and signalling.
TYPES OF PROTEINS BASED ON FUNCTION (ALTERNATIVE CLASSIFICATION)
· Enzymes: Facilitate biochemical reactions.
· Structural Proteins: Provide support and maintain the shape of cells and tissues.
· Transport Proteins: Assist in the movement of substances within the body.
· Regulatory Proteins: Control and coordinate various cellular processes.
· Hormones: Serve as signalling molecules, regulating physiological activities.
TYPES OF PROTEINS BASED ON SOURCE
- Animal Proteins: Derived from animal sources and considered complete proteins as they contain all essential amino acids.
- Plant Proteins: Obtained from plant sources and considered incomplete proteins as they may lack one or more essential amino acids.
