Recent surveys of dietary supplement use indicate that about 20 percent of active duty personnel are using some type of protein powder. The percentage of users is likely higher among special operations personnel, and this is of concern given the July 2010 Consumer Reports® Alert on protein drinks. These powder products are typically mixed with milk, water, or another liquid to make a shake and promoted as a sure way to increase muscle mass. The products often come in different flavors, with strawberry and chocolate the mainstays.
The Consumer Reports® Alert indicated that most of the 15 protein drink products analyzed contained miniscule to concerning amounts of selected contaminants – arsenic, cadmium, lead, and/or mercury – each of which is toxic to various organs in the body. Military personnel commonly use several of the products noted in the report. These include EAS Myoplex Original Rich Dark Chocolate Shakes; Muscle Milk chocolate, vanilla crème, and nutritional shake beverages; MuscleTech Nitro-Tech Hardcore Pro-Series Vanilla Milkshake; selected GNC products, and BSN and Optimum Nutrition whey protein products.
It is important to note that if three servings of these products were taken per day, consumers could be ingesting amounts of these contaminants in excess of the maximum limits proposed by the United States Pharmacopeia, the authoritative standard for health products. Importantly, toxic effects have been reported from using these products and are of concern because the Food and Drug Administration does not require such products to be tested to confirm the absence of contaminants and other potentially dangerous products before they are sold.
Take Home Message: A chicken breast, three 8-oz glasses of milk, and three eggs are inexpensive sources of high quality protein, whereas protein powders are expensive sources of uncertain quality, and potentially contaminated, protein. It is both better and cheaper to eat real foods.
