Should You Be Worried About Contamination in Greens and Whole Foods Products? February 20 2016
Contamination a Common Problem in Greens and Whole Foods Products According to ConsumerLab.com
White Plains, New York July 8, 2013
Greens and whole foods powders and pills, made from wheat grass, alfalfa, kelp, spirulina, leafy vegetables and other chlorophyll-containing ingredients, as well as fruits, were recently tested by ConsumerLab.com for potential contamination with heavy metals, microbes, and pesticides. ConsumerLab.com found that only 5 of the 11 products selected for testing met its quality standards. Powders that failed testing were contaminated with lead, arsenic, or bacteria, and a pill failed to properly break apart. Americans purchased $834 million worth of greens products in 2011 and the products represent an expanding market, according to Nutrition Business Journal.
Greens and whole foods powders and pills can provide a range of vitamins and natural antioxidants, and they tend to be high in fiber and low in fats, cholesterol and sodium,Â” said Tod Cooperman, M.D., President of ConsumerLab.com. However, being of made from plants and other natural ingredients, a product can be contaminated by the heavy metals or microbes that accumulate in those materials. It's not uncommon for a greens product to list more than a dozen plant-based ingredients -- if one is highly contaminated, it can spoil the entire product.
ConsumerLab.com found 6 mcg to 11.6 mcg of lead per daily serving in three products, representing significant and unnecessary exposure to lead, which is a toxin (All Day Energy Greens, Gary Null's Green Stuff, InnerLight Super Greens). One powdered product contained a high level of arsenic, a carcinogen (Vibrant Health Green Vibrance); a single serving of the powder (to be mixed in a cup or half-cup of liquid) contained 24.3 mcg of arsenic, which is more than twice the amount allowed by the U.S. EPA in a liter (4.3 cups) of drinking water. Another product contained a large amount of bacteria, suggesting unsanitary handling (The Ultimate Meal). A product in pill form failed to break apart properly in disintegration testing (Now Spirulina).
The cost per suggested serving of the "Approved" powders ranged from 37 cents (Swanson GreenFoods Green Max Powder) to $1.30 (Puritans Pride Lifes Greens). The only Approved pill, Juice Plus+ Garden Blend cost 65 cents per daily serving (2 capsules). Some of the most expensive products were those that did not pass testing, such as Gary Nulls Green Stuff at $2.24 per serving and Ultimate Meal at $4.75 per serving

Since ConsumerLabs were evaluating Greens and Whole Foods Products, they only tested the Juice Plus+ Garden Blend capsules.
It's no surprise that Juice Plus+ passed all their tests, but given the quality and proven effectiveness of Juice Plus+ it IS surprising that it is also one of the least expensive.
