Drinking too many protein shakes can load you up with cancer-causing toxins like arsenic, lead and cadmium – the chemical used to make batteries.
We read about this study on the Consumer Reports website.
Store shelves are full of ready-to-drink protein shakes, and big canisters of protein powder. They’re all used to build muscle mass, get a fast energy fix or to replace meals. If you have a regular workout regime or you’re always on the go, these kinds of shakes can be a quick, easy way to pump yourself with protein.
But researchers say there’s poison along with the protein. Dr. Urvashi Rangan and a group of scientists tested 15 different types of protein shakes and found each one contained arsenic, cadmium, lead or mercury. In fact, drinking just 3 protein shakes a day can expose you to more of these metals than is safe to consume daily.
So if you live off protein shakes what can happen?
Once chemicals like arsenic or lead get in your body they metabolize and can stay in your system for a long time. They’re known to cause cancer, and lead can also damage your central nervous system, kidneys and blood cells.
And federal regulations don’t require protein drinks to be tested for contaminants.
So, what can you do to stay safe?
Eat your protein – don’t get it from a mix. A chicken breast, a glass of milk, and 2 scrambled eggs will give you more than enough protein for an entire day, over 60 grams.
