Earlier this year, a nonprofit group called the Clean Label Project released a report about toxins in protein powders. Researchers screened products for types of toxins and found that many protein powders contained heavy metals lead, arsenic, cadmium, and mercury , bisphenol-A BPA, which is used to make plastic , pesticides, or other contaminants with links to cancer and other health conditions. Some toxins were present in significant quantities. For example, one protein powder contained 25 times the allowed limit of BPA.
How could protein powder contain so many contaminants? The Clean Label Project points to manufacturing processes or the existence of toxins in soil absorbed by plants that are made into protein powders. Not all of the protein powders that were tested contained elevated levels of toxins. You can see the results at the Clean Label Project's website www.

For people it means that, for example, it is good to have some toast with your eggs because the grain proteins compliment the egg proteins in terms of available amino acids.
