“That’s not a difficult amount to get in your diet, if you include natural sources of protein such as legumes, nuts, low-fat dairy, fish, and lean meats,” says Siegel. Protein needs range from 0.4 to 0.6 grams of protein per pound of weight a day (that would be 64 to 96 grams per day for a 160-pound person). By comparison, a 5-ounce container of plain, nonfat Greek yogurt has around 17 grams of protein, and 3.5 ounces of chicken breast has 31 grams. Protein products typically contain between 15 and 25 grams of protein per serving (although some do contain more). However, the vast majority of people get plenty of protein from the foods they eat, says Maxine Siegel, R.D., who heads CR’s food testing lab. Given the number of protein powders and drinks on store shelves, you might think that Americans are woefully deficient in this nutrient. “When you have a protein supplement that is very, very clean,” he says, “that proves, to the companies with high levels of heavy metals, that it is possible to do better.”
Given this goal, he says, you have to measure how each product stacks up against the others. Bowen has one possible theory, though: The cacao plants used to make the chocolate in some flavored supplements are susceptible to absorbing heavy metals.ĬR’s Akinleye says it would be very difficult to create a system where protein powders contained absolutely no trace of any heavy metals. However, the vanilla aspect is more curious, and possibly coincidental. whey-based proteins and their differing absorption of toxins. The fact that the higher-scoring products are made with whey makes sense, in keeping with Callan’s theories on plant-based vs.

In its analysis, the Clean Label Project assigned each product a score for four individual elements: heavy metals, pesticides, contaminants like BPA, and nutrition.
“That probably has more to do with these products being plant-based than being organic,” says Callan. In fact, organic protein supplements had higher levels of heavy metals, on average, than nonorganic. Callan suspects the animals' digestive systems diffuse some of the toxins.Īlso important: Buying a product with an "organic" label did not reduce the chances of getting a contaminated product. Whey and egg proteins may have lower levels of heavy metals because the source of the contamination would likely be the feed given to the animals. Plant-based proteins may have higher contamination levels because the plants are especially prone to absorbing heavy metals from soil, says Sean Callan, Ph.D., a neuroscientist and director of operations at Ellipse Analytics, the lab that tested the protein products. For more on that and today's update, visit the Heavy Metal Machines site.Overall, the products made from sources of plant protein such as soy or hemp fared worse than those made from whey (milk) or egg, containing on average twice as much lead and measurably higher amounts of other contaminants. If you're of a competitive mood, prepare yourself for the fifth season of the Metal League, which kicks off one month from today, Aug. Oh, and he also "has now transformed into a Golem so that he may cheat death and stay in the hunt for all eternity." I guess he doesn't have to worry about his 401(k), then.
