Khaberni - A study prepared by the independent American Consumer Association "Consumer Reports" revealed that a number of protein powders available in the market contain high levels of lead, raising serious concerns about the safety of these products that are widely consumed.
According to the results of the study, published on Tuesday, more than two-thirds of the 23 protein powders tested contain amounts of lead exceeding the safe daily recommended limit (0.5 micrograms), with two products recording high levels that led the association to recommend not using them at all.
"Consumer Reports" clarified that the average concentrations of lead in these products have increased compared to previous years, warning of the health risks associated with the accumulation of heavy metals in the body.
The lead researcher, Tunde Akinleye, stated, "The results suggest avoiding the daily use of protein powders, as most of them contain levels of heavy metals with no nutritional justification," emphasizing that obtaining protein through natural food is sufficient to meet daily needs.
These results come at a time when dietary supplements rich in protein are increasingly popular in the United States and Europe, driven by beliefs about their role in enhancing muscle mass and the sensation of satiety, while nutrition experts believe that excessive consumption may do more harm than good.
