Some Protein Powders are Unsafe: Study
We love ourselves a good smoothie, but did you know that even the healthiest of smoothies may be doing more harm than good for you? That scoop of protein powder that you’re adding may contain lead, cadmium, and/or BPA (an industrial chemical otherwise known as bisphenol-A).
Clean Label Project, a nonprofit focused on health and transparency in consumer product labeling, released the findings of a study on protein powders and the results are startling.
The 2018 study examined 134 protein powder products from 52 brands. Those products were tested for more than 130 toxins that included heavy metals, BPA, pesticides, and other contaminants with links to cancer and other health issues. We may think that what is on our shelves is safe to consume, and while the FDA has made significant strides to protect us consumers from foodborne illnesses, the USA lags behind countries such as France that have already boosted efforts to improve the quality and purity of foods fed to the nation. While the Clean Label Project is an American organization, many of the products tested can be found in Canada.
“We pulled over 130 of America’s best selling protein powders in accordance with Nielson data, the Amazon.com best seller list, and supplemented that list with top sellers in the natural/organic retail channel and consumer favorites mentioned on fitness blogs and websites,” stated the Clean Label Project website.
Contaminants found in protein powders are a result of sourcing and production practices, according to the Clean Label Project. “Contaminants can be found in soils because of pesticides and mining run-off and can be absorbed into plants just like nutrients. They can also be the result of the manufacturing process (BPA/BPS is using the lining of cans and containers and leach into the protein powder).”
Lead toxicity can cause infertility, nerve disorders, and cognitive difficulties while consuming unsafe amounts of cadmium can lead to kidney damage or cancer. BPAs have been linked to thyroid disfunction, heart disease, and metabolic syndrome.
Brace yourselves for some of the findings:
PLANT-BASED VS. NON PLANT-BASED
Of those protein powders tested, products with egg as a protein source tested cleaner.
Products that were plant-based as a protein source tested the worst.
A whopping 75% of plant-based products tested positive for lead.
ORGANIC VS. NON-ORGANIC
Non-organic protein powders contained up to 1.5x more arsenic than organic powders.
Non-organic protein powders contained up to 4.8x more cadmium than organic powders.
Non-organic protein powders contained up to 1.5x more lead than organic powders.
