You may have
read or heard about the article on protein drinks, published in the July 2010
issue of Consumer Reports magazine.
Alarmed? You should be, but not about the dangers of protein drinks. You should
be alarmed about the hack job that Consumer
Reports printed on this inept, one-sided investigation.
If you have no
idea what I'm talking about, visit: http://pressroom.consumerreports.org/pressroom/2010/06/investigation-tests-reveal-contaminants-in-many-protein-drinks.html
Let me start by
addressing the most ridiculous claim in the report: too much protein is
dangerous. If you wonder why the authors didn't cite any research to support
this bold statement, it's because none exists. In fact, several studies have
been done that show the exact opposite -- that high protein intake is not only
safe but also effective for building muscle size and strength, as well as
losing bodyfat.
Consumer Reports goes on to interview so-called health
and fitness experts on the supposed dangers of consuming too much protein. But
these "experts" are merely dieticians, not researchers in the field of sports
nutrition. One source is Kathleen Laquale, PhD, who says: "The body can break
down only 5-9 grams of protein per hour. Any excess that's not burned for
energy is converted to fat or excreted, so it's a ridiculous waste to be
recommending so much more than you really need."
Since I hadn't
heard of Laquale, I looked her up. Apparently, she's a professor in athletic
training at Bridgewater State College in Massachusetts. While I'm sure
Bridgewater State College is a fine school, it's not really a powerhouse in the
field of exercise science or sports nutrition. But even if it was, you should
know that athletic training deals with sports injuries, not sports nutrition.
Although Laquale is credited as a nutritionist, Pubmed does not contain a
single paper that she has published in a peer-reviewed scientific journal on
nutrition or any other research topic. Yet suddenly she's an expert on protein
utilization.
The problem is
that protein utilization is dependent on variables such as an individual's body
size, how long between meals, any activity (like exercise) he or she has
performed prior to the meal and the type of protein consumed. Laquale's blanket
statement is ridiculous and irresponsible, and it demonstrates that she has
little knowledge about sports nutrition.
Consumer Reports should have gone to real experts in the
field of protein research like Dr. Robert Wolfe. His research, conducted at the
University of Texas Medical Branch (Galveston), is pivotal to our understanding
of how critical protein is before and after workouts. In fact, our own
contributing writer Tabatha Elliott, PhD, did her postdoctoral work in Wolfe's
lab. I have spent time in Wolfe's lab learning techniques for studying protein
utilization to apply to my own research. Elliott and Wolfe could've told Consumer Reports that their research
actually shows that the more protein you consume, the more protein synthesis is
activated. Protein synthesis is the way that muscles grow bigger. In other
words, it takes more protein to build bigger and stronger muscles, and protein
drinks consumed at critical time periods in the day (such as before and after
workouts) are more effective for building muscle than whole-food protein
sources. To have random academics refuting what world-renowned experts in
protein research have shown to be true speaks volumes about how far out of
their depth the reporters were when they put this hack job together.
Then there's the
silly case report of poor little Scott Baker and his tummy aches. Baker's
dietician and personal trainer Erin Palinski claims that Baker experienced
diarrhea as a result of eating too much protein. Apparently Consumer Reports neglected to mention
that Palinski is also a gastroenterologist. She must be if she can diagnose
disorders of the intestinal tract. Again, Consumer
Reports includes comments from someone who's unqualified to make them.
But what about
the dangerous levels of heavy metals and other contaminants that Consumer Reports discovered in protein
drinks? Let's weed through the sensationalism of this report and remember this
statement, which comes early in their own article: "For most drinks we tested,
levels of those contaminants were in the low to moderate range, when we could
detect them at all." That's right, almost all the protein drinks and powders
tested didn't contain dangerous levels of contaminants.
But what about
the products that did contain high doses of contaminants? Let's examine the
findings. For starters, Consumer Reports
never discloses the methods used. NSF International, "The Public Health and
Safety Company" -- which is the world leader in standards development, product
certification, education and risk management for public health and safety, and
designated a collaborating center by the World Health Organization for Food and
Water Safety and Indoor Environment -- has issued a statement that refutes the Consumer Report findings:
NSF International cannot comment on the
test results reported in the July 2010 Consumer Reports
article on protein drinks. It omits critical information about the laboratory
that performed the test and its accreditation qualifications. ISO 17025
accreditation is critical for any laboratory testing for heavy metals in
dietary supplements and nutritional products. The article also omits the test
methods used, analytical preparation, sample size, the basis of their risk
assessment, detection limits, quality control data and instrumentation used for
this report.
The NSF
International statement further reads: Muscle
Milk Chocolate and Muscle Milk Vanilla Crème have been certified to NSF/ANSI
Standard 173. The samples analyzed met the maximum acceptable limits of the
standard based upon our validated test methods.
In other words,
NSF International, the world leader in such testing, has already found these
products to meet their standards. Yet Consumer
Reports somehow found levels of contaminants that NSF failed to find yet
did not disclose their method of finding them. Really?! This is yet another
claim by Consumer Reports that's just
ridiculous.

International's full report, go to:

If you're
wondering why any amount of arsenic, lead or mercury is in protein drinks, you
can't blame the supplement companies. The contaminants come from the whole-food
sources from which the protein drinks are made. It's almost impossible for food
not to contain trace elements of such contaminants. And yes, we consume low
levels of them whenever we eat whole foods. So if you want to completely avoid
these contaminants, you need to avoid a lot more than protein drinks. You'll
also need to avoid much of the food you eat on a daily basis. For some reason, Consumer Reports fails to mention that.
The bottom line
is that Consumer Reports was
obviously biased against protein drinks and the supplement industry when it
embarked upon this report. They neglected to interview any qualified protein
experts, didn't investigate any existing reports about protein powders' safety
and then they disregarded their own findings.
If this
"investigation" does anything, it should anger you. After all, they're supposed
to be the watchdog that protects your rights and safety. But this time, they
dropped the ball in favor of some easy reporting and junk science. If M&F relied on this kind of shoddy
research in our articles, we would've been out of business a long time ago.
