Protein powders under scrutiny: Hidden health risks revealed
Scientists from Harvard in the United States warn of potential dangers associated with the use of protein powders, which may contain harmful substances.
Protein powders are a popular dietary supplement, particularly among physically active individuals aiming to increase muscle mass.
In addition to consuming high-protein foods such as chicken, steak, fish, and eggs, protein powders serve as a useful supplement to help achieve this goal. However, Harvard scientists highlight the hidden dangers linked to their consumption.
Kathy McManus, director of the Department of Nutrition, stresses that she does not recommend using protein powders unless in special circumstances and under supervision.
Research conducted by the non-profit organisation Clean Label Project has revealed that many protein powders contain heavy metals such as lead, arsenic, cadmium, and mercury, in addition to bisphenol-A (BPA), pesticides, and other contaminants associated with cancer and additional illnesses.
"People with dairy allergies or trouble digesting lactose [milk sugar] can experience gastrointestinal discomfort if they use a milk-based protein powder," says McManus.
In some cases, BPA levels exceeded acceptable standards by up to 25 times.
Alternatives to protein powders
McManus suggests there are various ways to provide the body with protein without relying on powders. Plant-based alternatives include lentils, chickpeas, tofu, and nuts.
However, for older adults recovering from cancer treatment or dealing with wound-healing issues, chemical-free protein powders might be beneficial.
Excessive protein in the diet can also strain the kidneys, especially for individuals with existing kidney conditions. Therefore, it is always advisable to consult a dietitian or doctor.
