Health claims for coconut water: water works really well

The big surprise in Michael Moss’s tough look at health claims on coconut water in today’s New York Times—worth looking at online for the terrific video—is this:

One Last Comparison

These days, coconut water’s big rival may be plain old water. How do they compare? Scientists are still wrestling with the question, and while their findings vary, water is starting to look just fine for most people. A 2012 study (funded by Vita Coco) in the Journal of the International Society of Sports Nutrition found that neither coconut water nor sports drinks were better than water in hydrating young men after hourlong workouts.

Really?  An industry-funded study that comes to a conclusion against the interest of the funder?

This requires a look at the original paper.

So a round of applause please for the authors who did this funded study, “Comparison of coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men,” and nevertheless came to this conclusion:

Our data indicate that both coconut water (natural, concentrated and not from concentrate) and bottled water provide similar rehydrating effects as compared to a carbohydrate-electrolyte sports drink.  Moreover, none of the beverages impacted treadmill exercise performance differently during the rehydration period.

Lest there be any ambiguity about what this means, their data clearly show that VitaCoco, a sports drink (not named but I’d bet on Gatorade), and coconut water from concentrate all rehydrated men who spent 60 minutes on a treadmill to the same extent.

In other words: for rehydration, water works just as well as coconut water or sports drinks.   No surprise, really.

VitaCoco must be disappointed, but it still has one thing going for it: coconut water tastes really good.

Last call for comments on proposed food label: more on Added Sugars

August 1 is the deadline for filing comments on FDA’s food label proposals.

Two were released yesterday, one for and one against.

The Union of Concerned Scientists (UCS) organized a statement in support of listing added sugars signed by 280 scientists, physicians, and public health officials (including me).

The press release says:

In a letter submitted as a public comment for the agency’s first label update since 1994, the signatories point out that sugar overconsumption contributes to diabetes, cardiovascular disease and other ailments….Many food and beverage manufacturers add excessive amounts of sugar to their products, including those that they market as healthy options. In our current food environment, many people are unknowingly and unavoidably consuming excess sugar. Given our soaring rates of chronic diseases and the link between sugar and these diseases, citizens have a right to know how much sugar has been added to their foods.

People who signed the letter include many from Healthy Food Action, a national network of health professionals founded by Dr. David Wallinga.  I am a co-author of the statement with UCS staff and Dr. Robert Lustig.

In contrast, the American Society for Nutrition (ASN), an organization of nutrition scientists to which I belong, produced a strong statement against labeling added sugars.

ASN also has concerns that the inclusion of added sugars on the label may divert attention away from total calories and other important contributors to weight gain. The inclusion of added sugars on the label may confuse consumers and create the perception that naturally occurring sugars are somehow more beneficial because they are “natural” and do not have health effects similar to added sugars…There is no supporting evidence that indicates that the inclusion of added sugars on the food label will translate into the American public reducing caloric intake from added or total sugars or total energy intake…it is important to consider potential unintended consequences of  reformulation as well. When sugar is removed from a solid food product…The replacement is often fat and/or starch which could lead to a product with higher calories per serving. ASN encourages FDA to carefully consider potential adverse consequences of this proposed determination, including gaining input from food scientists…An investment in consumer education… is likely to be most productive for consumer understanding relative to added sugars, and would assure that consumers do not experience increased confusion, which they may encounter if added sugars are declared on the Nutrition Facts label.

These comments, which read as though written by sugar trade association groups, were signed by the president of ASN.  Although the statement letter gives no indication of the process by which these comments were developed, I’m told it was prepared by ASN’s public policy committee.

If so, it would help to know whether members of the committee have financial ties to the sugar industry or to food companies that use sugar in their products.

I wonder how much of the ASN membership agrees with this position on Added Sugars.   I certainly don’t.

On deadline: comments on FDA’s food label proposals

The FDA is taking comments on its proposals to revamp the food label through August 1, 2014 (instructions are at bottom of post).

I’ve already filed comments on Added Sugars and on whether Vitamin D should be added to food labels.

And I just filed further comments on the FDA’s proposals for the Nutrition and Supplement Facts Labels.  If you would like to read what I said, click here.

I’ve also filed comments on the FDA’s Serving Size proposals.

These proposals are highly technical and tough to slog through, so I tried to deal with the big picture.

July 27, 2014

TO:                  FDA

FROM:           Marion Nestle, Professor of Nutrition, Food Studies and Public Health, New York University

RE:                  Comments: Serving size proposals, Docket No. FDA-2004-N-0258

In addressing the question of how to change serving size designations on food labels, FDA is faced with an impossible dilemma .  Serving sizes, which are supposed to be based on amounts typically consumed from packaged products, are invariably perceived as recommendations for dietary intake.

To comment on each of the bold-face, italicized points:

  • Typically consumed:  This information derives from dietary intake surveys which invariably underestimate actual intake, often by 30% to 40%.
  • Packaged foods: Food labels only appear on packaged foods.  RACC amounts on packaged foods are often much lower than amounts served in restaurants or fast-food places (pizza is an obvious example).  It is unclear whether amounts reported as consumed are from packages (with Nutrition Facts labels) or are from restaurants or fast-food places where portion sizes can be much higher than those for foods in packages.
  • Recommendation:  Substantial anecdotal information suggests that people view labeled serving sizes as what they should be eating.  They view the serving sizes as meaningless compared to the portion sizes of foods they are accustomed to eating.

What is well established is that overall calorie intake has increased since RACCs were established in 1993 and marketplace portion sizes have also increased.

Therefore, any increase in RACC runs the risk of being interpreted as a validation of current portion sizes and as a recommendation to eat more.

On the other hand, larger portions have more calories.  These must appear on the label.

To address this dilemma, FDA should:

  • Make dual-column labeling mandatory for all food and beverage packages likely to be consumed in one sitting.
  • Require total calories in the package to be displayed on the front of the package.
  • Include a footnote explaining that the serving size is not meant as a recommendation

Weekend thinking: NutraIngredients-USA’s special edition on cognitive health 

The role of specific nutrients in brain health isn’t something I think about much.  I’m of the opinion that a reasonably healthy diet takes care of health.  Stop worrying, be happy.

But I’m always interested in what the food industry is cooking up based on current research, and here’s a good sampling to ponder.

For this Special Edition, NutraIngredients-USA has a long hard think about cognitive health…

Cognition spans the lifetime, from development in the womb right through to old age. So, which ingredients have the best science? How are companies approaching this sector and what claims can they make? What’s all this about the gut-brain axis? And what’s happening with botanicals in this space?

FDA’s food label proposals: comments on Vitamin D

The FDA is taking comments on label proposals until August 1 (see info at end of post).  Here’s mine on voluntary vitamin D labeling.

July 17, 2014

TO:  FDA

FROM:  Marion Nestle, Professor, New York University

RE:  Proposed revision to Nutrition Facts Panel: VITAMIN D

This is to argue against permitting food companies to voluntarily label added “Vitamin” D on the Nutrition Facts panel.  Doing so will not promote—and may possibly harm–public health.

Rationale

  • “Vitamin” D is not a vitamin; it is a hormone synthesized by the action of sunlight on skin.  For this reason alone, it does not belong on the food label.
  • Vitamin D fortification must be understood as a form of hormone replacement therapy.   As such, it raises questions about efficacy, dose, and side effects that should be asked about all such therapies.
  • Fortification and supplementation provide hormone Vitamin D by the oral route.  This is not physiological.  Active vitamin D is synthesized in the body through a series of reactions that begin with the action of sunlight on skin.  Sunlight on skin produces ample Vitamin D, is regulated to promote synthesis as needed and avoid toxicity, and may lead to synthesis of other useful biological components; the unphysiologic oral route does not produce the same benefits.[i]
  • As a hormone, Vitamin D is found naturally in very few foods (e.g., fish); in them, it is present in small amounts.  It is present in most foods as a result of fortification.
  • Permitting Vitamin D to be listed on food labels will encourage fortification, undoubtedly of foods that would not otherwise necessarily be recommended.  To cite just one example: Yum Bunny Caramel Milk Spread fortified with vitamin D at 10% of the DV.  This product is half sugars by weight, marketed as “a good source of calcium and vitamin D,” and clearly aimed at children. See: http://www.yumbunny.com/about-us.   Whether such products should be considered “good sources” also deserves scrutiny.
  • The U.S. Preventive Services Task Force concludes that evidence is insufficient to determine how Vitamin D supplementation (and, therefore, fortification) affects fracture incidence.[ii],[iii],[iv] 
  • Data from the Women’s Health Initiative also are consistent with largely inconclusive findings about hormone Vitamin D supplements and bone health.[v]
  • The Institute of Medicine (IOM) does not consider deficiency of Vitamin D to be a serious problem in the United States, except among certain population groups.  Instead, because of widespread fortification and supplementation, it is concerned about the possibility of adverse consequences from overconsumption through supplementation or fortification.[vi]
  • Many scientific debates about hormone Vitamin D are as yet unresolved.[vii],[viii]  
  • The lack of compelling research has permitted Vitamin D to become “trendy.”  It is advertised on boxes of fortified cereals, has its own pro-supplement advocacy group, and generates millions in annual supplement sales.[ix]

In the absence of stronger evidence for benefit from fortification, and some evidence for possible adverse consequences, the FDA should not contribute to further commercialization of this misnamed hormone by permitting it to be listed on food labels.

The White House says “Drink Up,” meaning water

Living in New York as I do, I miss the fun in Washington, DC, of which there was much yesterday related to the First Lady’s “Drink Up” campaign with the Partnership for a Healthier America.   Here’s one of ObamaFoodorama’s tweets on the event.

Screenshot 2014-07-23 07.58.20

Listen to what the First Lady is saying in these selected quotes, some of which deal with the current furor over school meals:

  • When the Drink Up campaign was launched last year, it had one simple goal – to get kids and families excited about drinking water.
  • As Drink Up encourages more people to drink more water, we also want to help make choosing water an easier choice…water for more people wherever they are, whenever they want it, however they want it – be it tap, filtered or bottled.
  • In a number of school districts, participation in the lunch program has actually risen. And there’s a simple reason for that: It’s because those districts actually put some effort into marketing the new meals to the kids. They didn’t just sit back and say, well, the kids like junk food so let’s just give them junk food.
  • Instead, they embraced higher standards and more nutritious options, and they worked hard to get the kids excited about them. They did taste tests. They came up with new recipes. They did everything they could to make healthy eating fun.
  • Today, we’re seeing the results, especially among younger kids…They’re getting used to healthier food, and they’re developing healthy habits early on that will stay with them for the rest of their lives. And that’s our job as adults… And no matter what, we don’t give up on our kids. And we don’t give up on their health and their futures.
  • We need to keep pushing to market healthy products to children and families. We need to keep working together within industries and across industries to help our kids lead healthier lives.

Even better, The California Endowment announced that it will increase community access to water in South Kern County and the Eastern Coachella Valley by installing hundreds of taps and dispensers to fill reusable water bottles in schools and public places.

Let’s have more tap-water initiatives, please.

The more people drink tap water, the greater will be public support for maintaining the quality of municipal water supplies.

Addition, July 24:  The School Nutrition Association wrote the First Lady to complain that it found her remarks offensive.

Rest in Peace Mickey Stunkard

The Times’ obituary for Dr. Albert J. (“Mickey”) Stunkard, who died last week at the age of 92, describes his work on the genetics of obesity and quotes Dr. Walter Willett’s comment that genetics accounts for only a small part of the “legions of the obese.”

Stunkard was writing about the lifestyle and environmental determinants of weight gain, long before most of us had a clue.

I learned this in 2000 when Michael Jacobson and I were writing a paper on public health policy approaches to obesity prevention.[i]   We were arguing that policies aimed at preventing weight gain focused almost entirely on personal behavior but needed to focus on fixing the environment of food choice.

A peer reviewer scolded us for missing Stunkard’s work.

At last, we discovered Stunkard’s groundbreaking work.  In the published paper, we wrote:

The most notable exception [to the focus on personal responsibility] was the report of a 1977 conference organized by the National Institutes of Health (NIH) to review research and develop recommendations for obesity prevention and management.

In one paper, A.J. Stunkard thoroughly reviewed social and environmental influences on obesity.[ii]  As a result, the conference report included an extraordinarily broad list of proposals for federal, community, and private actions to foster dietary improvements and more active lifestyles.

These ranged from coordinated health education and model school programs to changes in regulations for grades of meat, advertising, taxes, and insurance premiums. Some of the proposals cut right to the core of the matter: “Propose that any national health insurance program…recognize obesity as a disease and include within its benefits coverage for the treatment of it.” “Make nutrition counseling reimbursable under Medicare.” And “Fund demonstration projects at the worksite.”[iii]

He was far ahead of his time and will be greatly missed.

This week’s reading: The GMO Deception

Sheldon Krimsky and Jeremy Gruber, eds.  The GMO Deception: What You Need to Know about the Food, Corporations, and government Agencies Putting Our Families and Our Environment at Risk.  Skyhorse Publishing, 2014.

I did a blurb for this one:

GMO Deception brings together essays by specialists in a wide range of fields united in skepticism about the benefits of GMOs for reasons grounded in in biology, social science, politics, and ethics.  If you do not understand why there is so much opposition to GMOs, nationally and internationally, this book is the place to start.
