That five-pound jar of protein powder on your kitchen counter looks totally hardcore, but you might want to think before you mix your next post-workout power shake: Consumer Reports says that some protein drinks may cause health problems over time, and the people selling them to you don’t want you to know about potential risks. In a hidden camera investigation of nutrition stores in New York City, not one employee warned undercover reporters about risks; in fact, one employee said that consuming more protein drinks will make you gain more muscle. Drinking too much protein can lead to dehydration, digestive problems, increased osteoporosis risk, and kidney problems.
When 15 different types of protein drinks were tested for heavy metals, they all contained arsenic, cadmium, and lead. Cumulative exposure over time could lead to a build-up of these toxic metals in the body, which is a definite health risk. The FDA needs to look more closely at these drinks and powders, which are commonly sold in health food stores, to determine if they pose more health problems than benefits.
