Protein has become a key focus in fitness and nutrition, valued for its role in building muscle, supporting weight management, and promoting overall health. Despite these benefits, misconceptions about protein—particularly protein powders—remain widespread in India, causing unnecessary fear. In a viral Instagram video shared on 12 August, neurosurgeon Dr Arun L Naik addressed one of the most persistent myths: that protein powders harm the kidneys. He emphasised that this belief is scientifically incorrect and potentially dangerous, as it prevents people from meeting their daily protein requirements. Dr Naik stressed that adequate protein intake is essential for muscle maintenance, metabolism, and overall wellbeing, and supplements are safe for healthy individuals when consumed in moderation and alongside a balanced diet rich in natural nutrients.
Role of protein in repair, growth, and vital body functions
Protein is an essential macronutrient that supports almost every function in the body. It helps in repairing tissues, forming enzymes and hormones, and maintaining muscle mass. According to the Mayo Clinic, an average sedentary adult requires 0.8 grams of protein per kilogram of body weight to avoid deficiency.
Dr Naik explained in his video that protein should not be feared, even when taken through supplements like whey protein. Instead, it should be recognised as a necessary nutrient for muscle health, metabolism, and heart function.
He pointed out that the fear of protein supplements has been exaggerated by misinformation and cultural bias, leading many to believe they are harmful to the kidneys. But, as he clarifies, the science says otherwise.
Protein and kidney health myth: Why supplements are safe for healthy adults
Addressing the long-standing myth, Dr Naik began by quoting a familiar warning:
“Protein powders will damage your kidneys, and you don’t need much protein for your health. We doctors and your parents are saying this, right?”
He immediately followed with the truth:
“Wrong. This is a hoax that’s killing more Indians than protein ever will.”
According to Dr Naik, protein does not damage healthy kidneys. The kidneys are capable of processing protein efficiently, and consuming a reasonable amount through food or supplements poses no danger. The only situation where protein intake must be monitored is when a person already has severe kidney disease—a condition that affects a small fraction of the population.
In healthy individuals, protein supports vital processes such as muscle maintenance, brain function, and immune health. Dr Naik’s message is clear: protein is not the problem—ignorance about it is.
Indians and the problem of protein deficiency
One of the central points of Dr Naik’s video was that India is a protein-deficient country. He explained that traditional Indian diets once included a variety of protein-rich foods such as lentils, pulses, dairy, eggs, fish, and meat. However, over time, these have been replaced with refined carbohydrates like polished rice, white flour, and sugary foods.
Dr Naik explained:
“Our ancestors ate high-protein diets: lentils, pulses, dairy, meat, and fish. However, over the centuries, we have swapped that for polished rice, refined wheat, sugar, and unhealthy oils.”
This shift has led to widespread nutritional imbalance. As carbohydrate intake increased and protein consumption fell, Indians began to face rising rates of fat gain, insulin resistance, and chronic inflammation—a dangerous trio that contributes to heart disease, diabetes, and strokes.
Dr Naik argues that instead of blaming protein, people should look at sugar, refined carbs, and sedentary lifestyles as the real causes of health decline.
Protein and its impact on heart health
Dr Naik also drew attention to a global trend: countries with higher protein intake have lower rates of lifestyle-related heart disease. This observation, he said, is a clear indication that protein is beneficial, not harmful.
A diet rich in protein helps maintain lean muscle mass, improves metabolism, and stabilises blood sugar levels. It also supports a healthy balance between energy intake and fat storage. In contrast, excessive consumption of refined carbohydrates causes spikes in blood sugar, fat accumulation, and systemic inflammation—all of which strain the heart.
Dr Naik’s message is simple yet powerful: protein supports heart health, while refined carbs undermine it.
How balanced protein intake supports muscles, metabolism, and vital functions
While Dr Naik strongly defends the role of protein, he also clarifies that individuals with existing kidney disease need to manage their protein intake carefully, under medical supervision. For everyone else, however, protein is not harmful—even when consumed in the form of supplements like whey.
He stressed that balanced nutrition is key. Overconsumption of any nutrient is unhealthy, but moderate, consistent protein intake supports muscle repair, metabolism, and overall vitality. Dr Naik’s Instagram video serves as both a clarification and a call to action. He urges Indians to stop fearing protein and start addressing the real issues—high sugar intake, excessive carbs, and lack of physical activity.
He recommends restoring the balance that once existed in traditional diets by incorporating protein-rich foods such as pulses, paneer, eggs, yoghurt, and fish. For those who find it difficult to meet their daily protein requirements through food alone, protein powders can be a convenient and effective supplement.
Dr Naik concluded his message with a strong statement that has resonated with thousands online:
“Stop blaming protein. Blame the sugar, the refined carbs, and the sedentary lifestyle. Your heart, brain, and muscles are built on protein. Neglect it, and you pay the price.”
