12 Kolkata: Doctors have warned against indiscriminate consumption of whey proteins from an early age by gym-going teens and youths keen on building six packs and biceps who then develop ailments that range from acne and gastrointestinal issues to more complex problems that impact organs like the heart, kidneys and liver.
A 20-year-old IT student who did not have acne issues during his teenage years began to suddenly develop skin pimples. As the problem persisted, he went to consult a dermatologist who promptly identified the cause after learning that he was a regular gym-goer. It was unregulated intake of whey protein supplements for months that had sparked acne growth.
"We are seeing an increasing number of youngsters with acne issues. The majority of them are gym-goers who have been taking whey protein in an unregulated manner. There is enough data to suggest that excessive intake of whey protein can cause acne issues. While these acnes might look harmless, in the long run, they can develop into scars," said dermatologist Abhishek De, senior consultant at Wizderm.
Doctors said that whey protein is promoted in gyms as it is a rich source of proteins and amino acids like leucine and glutamine. This nutritious supplement offers numerous benefits when consumed in moderation, in addition to building muscles. The problem occurs when more of this supplement is consumed.
Upal Sengupta, director of nephrology at Fortis Hospital, Anandapur, said, for individuals weighing 50-60 kg, a daily intake of 25-50 g is recommended to support muscle growth, recovery, and weight loss. However, excessive and unregulated consumption may lead to potential health issues, including kidney infections and elevated creatinine levels.
"Gym trainers may recommend additional supplements not approved by medical professionals, which can harm kidney and liver health. Unfortunately, whey protein is often mistakenly blamed for these adverse effects, when it is a combination of excessive whey protein and other unapproved supplements that may be the culprit," Sengupta added.
Experts have linked high-protein sources with higher levels of saturated fats, increased blood sugar levels, and higher blood acidity. Whey protein can affect heart functioning as well, leading to cardiac arrhythmia, cardiac arrest, and other heart issues. "While consumption of the required amount is good, the problem is when its consumption is unregulated," said CTVS consultant Amanul Hoque of BM Birla Heart Research Centre.
