NY Times Editorial - Beware Claims About Foods

Snake Oil for Breakfast

More than a century after President Theodore Roosevelt signed the Pure
Food and Drug Act, deception is still a far too popular marketing tool
for food makers.

The Federal Trade Commission barred Kellogg’s last year from running ads
saying Mini-Wheats are “clinically shown to improve kids’ attentiveness
by 20 percent.” To claim “benefits to cognitive health, process or
function provided by any cereal or any morning food or snack food,” was
a no-no, unless the claims were true. But the F.T.C.’s order covered
only cognitive abilities. So just as it was signing its consent,
Kellogg’s was starting a new campaign in which “Snap, Crackle and Pop”
called out to parents from the Rice Krispies box promising to help
“support your child’s IMMUNITY.”

Last week, the F.T.C. said that it had closed that loophole, reaching an
agreement with Kellogg’s that would bar the company from making any
claims about the health benefits of their food unless they were backed
by scientific evidence and not misleading.

Businesses have been making dubious claims about their products at least
since the 17th century, when the British clergyman Anthony Daffy sold
Daffy’s Elixir as a cure for scurvy as well as agues, gout, rheumatism,
rickets, worms and other ailments. Hucksterism — no matter how
implausible the claim — lives on.

In 2004, the F.T.C. barred KFC from saying its fried chicken was
compatible with low-carbohydrate weight-loss programs — because such
diets specifically advise against breaded, fried foods. The Food and
Drug Administration sent letters to 17 food companies in March warning
them about misleading product labels. Dreyer’s claimed there is no
trans-fat in its ice cream but forgot to mention it has lots of
saturated fat. POM Wonderful claimed its pomegranate juice helps treat,
prevent or cure hypertension, diabetes and cancer.

This might be par for the course for an era of swift-boating political
ads and a torrent of television commercials plumping for myriad wonder
drugs (sudden death may result). It leaves the consumer in a quandary:
what part of the label can be believed?

Protein Drinks May Be Harmful



A study by Consumer Reports found that most people do not need to add a protein supplement to their diet and that some protein drinks contain contaminants and metals that can cause serious health problems.

Manufacturers of protein drinks once marketed only to body builders, athletes and health fanatics, however in recent years they have aimed promotion of these supplement products to busy professionals, working mothers, pregnant women, young adults and even children. Some protein drinks entice consumers with advertising claims including weight loss, muscle building, energy boosting or anti-aging. They encourage consumers not only to supplement their daily diet with these products, but also to use them to replace meals.

The Consumer Reports investigation sent fifteen protein drinks to an independent laboratory for analysis, reviewed government documents and interviewed health experts, fitness experts and consumers. They found that most people get enough protein in their regular diet and do not need these supplements. Consumer Reports recommends that people who need more protein, can find it in healthier, cheaper sources such as milk, eggs and chicken breast.

The results of the laboratory analysis found that all fifteen of the protein drinks tested contained one or more of the contaminants arsenic, cadmium, lead and mercury. Three of the products tested raised particular concern because consuming more than three servings per day could expose the consumer to levels of these contaminants that are above recommended limits:

- Eas Myoplex (Arsenic and Cadmium)
- Muscle Milk Chocolate (Cadmium and Lead)and;
- Muscle Milk Vanilla Crème (Lead)

“It is our company mission to do everything possible to ensure that our products are superior in quality, reliability, authenticity and safety,” said Greg Pickett, Founder of CytoSport, Inc. who manufactures Muscle Milk. “Additionally, our products are rigorously tested by both us and independent third party agencies including NSF International to ensure their safety and efficacy.”

The article detailing the study appears in the July 2010 issue of Consumer Reports Magazine. The non-profit consumer organization Consumers Union publishes the monthly periodical.

Watch the Early Show on CBS as they take a hidden camera into nutrition stores in New York City where salespeople failed to warn of dangers and even said taking more than the recommended doses would cause no harm.

“What we're concerned about here is the chronic low level exposure of a heavy metal. And what people should know, is that heavy metals, once they come into our bodies, once they're metabolized, they tend to stay there for a long period of time,” Urvashi Rangan of Consumer Reports told
CBS
. According to the American Heart Association, people who have an excess of protein in their diet may be at higher risk of kidney and liver disorders, and osteoporosis. While everyone can suffer adverse health effects from exposure to heavy metals, children, growing teens, pregnant women and their unborn children are especially at risk.

Lead exposure can cause developmental problems such as damage to the brain and nervous system or slowed growth in growing children and teens. In adults, it can cause reproductive problems, high blood pressure and hypertension, nerve disorders, effect memory or concentration or cause muscle and joint pain. Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels and a sensation of “pins and needles” in hands and feet. Cadmium is a known carcinogen, meaning cancer causing. Ingesting cadmium can damage kidneys and bones. Exposure to mercury can permanently damage the brain and kidneys. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing and memory problems.

“The results of this analysis aren't alarming,” Andrew Shao of the Council for Responsible Nutrition told CBS. “The heavy metals that were found are well below the limits FDA Food and Drug Administration) would be concerned about, so they don't pose a health risk to consumers at all.”

Chocolate Milk is a 'Natural' for Post-Exercise Recovery

New research suggests drinking chocolate milk after a workout offers advantages for post-exercise performance and muscle repair

BALTIMORE (June 2, 2010) – One of the best post-exercise recovery drinks could already be in your refrigerator, according to new research presented at the
American College of Sports Medicine conference this week. In a series of four studies, researchers found that chocolate milk offered a recovery advantage to help repair and rebuild muscles, compared to specially designed carbohydrate sports drinks.

Experts agree that the two-hour window after exercise is an important, yet often neglected, part of a fitness routine. After strenuous exercise, this post-workout recovery period is critical for active people at all fitness levels – to help make the most of a workout and stay in top shape for the next workout.

The new research suggests that drinking fat free chocolate milk after exercise can help the body retain, replenish and rebuild muscle to help your body recover. Drinking lowfat chocolate milk after a strenuous workout could even help prep muscles to perform better in a subsequent bout of exercise. Specifically, the researchers found a chocolate milk advantage for:

Building Muscle – Post-exercise muscle biopsies in eight moderately trained male runners showed that after drinking 16 ounces of fat free chocolate milk, the runners had enhanced skeletal muscle protein synthesis – a sign that muscles were better able to repair and rebuild – compared to when they drank a carbohydrate only sports beverage with the same amount of calories. The researchers suggest that "athletes can consider fat-free chocolate milk as an economic nutritional alternative to other sports nutrition beverages to support post-endurance exercise skeletal muscle repair."1

Replenishing Muscle "Fuel" – Replacing muscle fuel (glycogen) after exercise is essential to an athlete's future performance and muscle recovery. Researchers found that drinking 16 ounces of fat free chocolate milk with its mix of carbohydrates and protein (compared to a carbohydrate-only sports drink with the same amount of calories) led to greater concentration of glycogen in muscles at 30 and 60 minutes post exercise.2

Maintaining Lean Muscle – Athletes risk muscle breakdown following exercise when the body's demands are at their peak. Researchers found that drinking fat free chocolate milk after exercise helped decrease markers of muscle breakdown compared to drinking a carbohydrate sports drink.3

Subsequent Exercise Performance – Ten trained men and women cyclists rode for an hour and a half, followed by 10 minutes of intervals. They rested for four hours and were provided with one of three drinks immediately and two hours into recovery: lowfat chocolate milk, a carbohydrate drink with the same amount of calories or a control drink. When the cyclists then performed a subsequent 40 kilometer ride, their trial time was significantly shorter after drinking the chocolate milk compared to the carbohydrate drink and the control drink.4

Why Chocolate Milk?

Chocolate milk's combination of carbohydrates and high-quality protein first made researchers take notice of a potential exercise benefit. The combination of carbs and protein already in chocolate milk matched the ratio found to be most beneficial for recovery. In fact, studies suggest that chocolate milk has the right mix of carbs and protein to help refuel exhausted muscles, and the protein in milk helps build lean muscle. This new research adds to a growing body of evidence suggesting milk can be just as effective as some commercial sports drinks in helping athletes refuel and recover.

Milk also provides fluids for rehydration and electrolytes, including potassium, calcium and magnesium lost in sweat, that both recreational exercisers and elite athletes need to replace after strenuous activity. Plus, chocolate milk is naturally nutrient-rich with the advantage of additional nutrients not found in most traditional sports drinks. Penny-for-penny, no other post-exercise drink contains the full range of vitamins and minerals found in chocolate milk.
