FDA seeks input on issues related to dietary fiber

You might think that fiber simply refers to components of food plants that cannot be digested by human enzymes and are excreted in feces.

No such luck.

Like everything else in nutrition, fiber is complicated, not least because intestinal bacteria can digest some of those components and produce nutrients we can use.

In May, the FDA said that naturally occurring dietary fibers such as those found in fruits, vegetables and whole grains—and 7 specific isolated or synthetic fibers—could be declared on the label under “Dietary Fiber.”

The FDA defines fiber as (no, I’m not kidding):

non-digestible soluble and insoluble carbohydrates (with three or more monomeric units), and lignin that are intrinsic and intact in plants; isolated or synthetic non-digestible carbohydrates (with three or more monomeric units) determined by FDA to have physiological effects that are beneficial to human health.

The isolated or synthetic non-digestible carbohydrates said to have beneficial effects are:

  1. [beta]-glucan soluble fiber
  2. psyllium husk
  3. cellulose
  4. guar gum
  5. pectin
  6. locust bean gum
  7. hydroxypropyl methylcellulose

 

Cows and termites can digest cellulose.  We can’t.  But the FDA has evidence that they do other good things, for example, like lowering cholesterol.

The makers of processed foods love using these fiber additives for their various texturizing properties—and also because they can claim them as fiber on the label.

Now the FDA wants help in understanding whether 26 other kinds of isolated and synthetic fibers qualify as “Dietary Fiber” on food labels and, if so, what their beneficial effects on health might be.

The mind boggles.  This is another reason to stick with fruits, vegetables, and grains.

The comment period for the Request for Information opens on November 23, 2016 and will be open for 45 days.

FoodNavigator-USA’s Special Edition: Food allergy and intolerance

FoodNavigator.com does occasional “special editions” in which they collect articles on particular topics from the perspective of their food-industry audience.  This one is on food allergies and intolerances, about which remarkably little is known.  If you are allergic or intolerant, the best you can do is hope for an accurate allergy test or do everything you can to avoid the food that triggers reactions.  Good luck with that since allergies are hard to diagnose and allergenic ingredients sneak into a great many foods and are not always revealed on labels.

Rethinking nutrition policy in developing countries

I recently coauthored an editorial on international development.  It appeared first in French, and now in English in Ideas for Development, a blog coordinated by the French Agency for Development.

Rethinking nutritional policies in developing countries taking into account the double burden of malnutrition

By , Marion Nestle, and

The world now experiences two forms of malnutrition which may seem contradictory: “undernutrition” (which includes micronutrient deficiencies) and “overnutrition” (obesity and its health consequences).The problem of malnutrition in developing countries is approached by most aid bodies (donors, international organisations and NGOs) and governments solely from the angle of undernutrition. And yet in these countries, the complex and multi-faceted challenge which malnutrition now presents can justifiably be called the double burden of malnutrition. In addition to the continuing problem of undernutrition there are now major issues linked to overnutrition and its associated illnesses.

Rapid nutrition transition

The stereotyped image of skeletal young children with protruding bellies saved by souls of goodwill in sub-Saharan Africa is still too widespread. Severe acute malnutrition still persists of course, especially among the victims of extreme poverty, natural catastrophes and wars. Naturally, this deadly disease must continue to be addressed and treated, as numerous NGOs are doing.

The treatment of malnutrition should focus not only on severe malnutrition in children. Less severe malnutrition, going back to life in the foetus and resulting from malnutrition in women even prior to their pregnancy, continues to contribute to stunting, which affects 23.8% of all children under the age of 5 throughout the world.

In parallel with acute and chronic undernutrition, the “nutrition transition” in low-income countries, driven by globalisation, urbanisation and technological progress and linked to “overnutrition,” leads to a swift increase in obesity and other chronic diseases – mainly diabetes and cardiovascular diseases. Nutrition transition is the term used to describe the progressive Westernisation of eating patterns, typified by a sharp increase in the consumption of animal fats and processed foods all over the world, combined with an increasingly sedentary lifestyle. It is easy to see how this transition encourages the increase in overweight and obesity.

Today, undernutrition alone is not the major issue; the greatest problem is the double burden of undernutrition and overnutrition. According to estimates from 129 countries with available data, 57 experience serious problems of both undernutrition in children and overweight in adults[i]. And Africa is not exempt from this double burden where undernutrition and overweight are undeniably linked. In West Africa, 50% of women of child-bearing age are anemic while at the same time 38% are overweight and 15% are obese. For the whole of sub-Saharan Africa, 40% of children have stunted growth characteristic of chronic undernutrition, while 7.5% of adults suffer from obesity. Malnutrition early in life increases the subsequent risk of chronic diseases in places where obesity is encouraged by the environment. Obesity is now on the increase among children in all developing countries. The World Health Organization (WHO) reports that between 1990 and 2015 the number of overweight or obese African children doubled from 5 to 10 million. 

The responsibilities of the industrial food system

It is often said that communication aimed at changing food habits is the best way to prevent obesity, a problem reserved for rich people in low-income countries. This cliché contains three errors:

  • The first is the claim that preventing nutrition-related chronic relies entirely on the capacity of individuals to make appropriate choices regarding food, physical activity or lifestyle. This claim ignores the well-documented effects of the food system and the socio-cultural factors which play a determining role and which influence the choice of individuals.
  • The second error is to believe that significant changes cannot be made to the eating practices of limited-income groups in the absence of an increase in resources. Yet several studies show the opposite, whether they are about exclusive breastfeeding for the first six months of life and improved complementary feeding, or else hygiene measures and supplies of drinking water.
  • The third error is to consider that obesity continues to be only a problem of the rich in low-income countries. Obesity is escalating and affecting growing numbers of not so well-off people, particularly in cities.

When analysing the impact of the food system, it is necessary to account for the agri-food industry (Big Food). On a world-wide scale Big Food is primarily responsible for the nutrition transition” towards processed food. “Globalised” industrial food is gradually replacing traditional cooking and locally produced foods, with ultra-processed foods’ (food-like substances as Michael Pollan calls some of them) undeniable appeal for city-dwellers and young people as these products are strongly associated with Western-style fast food and heavily promoted by the media. This appeal is reflected in profound changes in consumption trends in developing countries. Global sales of highly processed foods increased by 44% from 2000 to 2013, but only by 2% in North America as opposed to 48% in Latin America and 71% in Africa and the Middle East.

So what is the problem? Industrial food products (and drinks) are often a nutritional disaster: rich in calories, sugar, fat and salt, but low in essential nutrients and fiber. Even more, these products are relatively inexpensive, often less expensive than more nourishing local food products.

Changing the food environment

What is the explanation for the popularity of these “globalized” food products? Part of the answer lies in extremely effective advertising. Anyone travelling in Africa, for example, will see campaigns to promote salty stock cubes to replace traditional spices and vegetables. “Social marketing” efforts to change eating behaviour must be as forceful as these adverts, with commensurate budgets.

One idea is to impose a tax on soft drinks or other highly processed foods and use the revenues to finance cutting-edge nutrition education campaigns. This is what the United Kingdom has recently decided to do by taxing soft drinks.

It is especially important to rethink the nutrition programs created by NGOs and financed by international aid. Correcting the nutrition of malnourished mothers or children is only part of the problem.

A wider vision is needed to recognize the threat to world health posed by nutrition-related chronic diseases.

To cope with this new challenge, it will be important to address many determinants of health – education, social disparities, housing, and culture – as well as the food environment. The latest report on global nutrition1 points out the excellent return on investment of nutrition interventions (16 for 1), and challenges governments and decision-makers to identify and implement strategies that target the double burden of malnutrition. If this is not done, it will be difficult to reach the nutrition objectives set by the WHO for 2025 (see below). Solutions do exist, however, as can be seen from places such as Ghana, Brazil, or the state of Maharashtra in India, which have had encouraging results in fighting malnutrition in all its forms.

Global nutrition targets for 2025

  • Reduce the number of children with stunted growth by 40%
  • Reduce and keep the prevalence of acute malnutrition in under-five children (low weight) under 5%
  • Avoid any increase of overweight in children
  • Reduce the prevalence of anemia in women of child-bearing age by 50%
  • Increase exclusive breastfeeding for babies less than 6 months old by 50%
  • Reduce low birth weights by 30%
  • Avoid any increase in the prevalence of overweight, obesity and diabetes in adults.

What does “healthy” mean (on food labels)?

As it promised in response to a petition from the KIND fruit-and-nut bar company (as I discussed in a previous post), the FDA is now asking for public comment on what “healthy” means on food package labels.

You might think that any food minimally processed from the plant, tree, animal, bird, or fish would qualify.

But “healthy” is a marketing term for processed food products (not foods).  

As Politico Morning Agriculture reminds us, things got complicated when KIND, which makes products from whole nuts, said its bars deserved to be called “healthy.”

In 2015, KIND received a warning letter from FDA arguing the company violated federal rules by using “healthy” on its packages. KIND then petitioned the agency, and, after an exchange about why the current definition is outdated, FDA decided to reverse course. For example, it requires that a food be low-fat to be labeled “healthy,” a standard that a nut-based bar doesn’t meet, while products like fat-free puddings do.

The FDA’s rules now say:

The term “healthy” and related terms (“health,” “healthful,” “healthfully,” “healthfulness,” “healthier,” “healthiest,” “healthily” and “healthiness”) may be used if the food meets the following requirements: 21 CFR 101.65(d)(2)

OK.  I know you can’t read this (you can look for it here). The point is that to qualify as “healthy,” a product has to be low in fat, saturated fat, and cholesterol; relatively low in sodium; and contain at least 10% of the Daily Value per serving for vitamins A or C, calcium, iron, protein, or fiber (with some exceptions).  There are also rules for levels of nutrients added in fortification.

The FDA wants input on whether all of this makes sense in the light of the 2015 Dietary Guidelines and the KIND petition.

In its inimitable FDA-speak:

While FDA is considering how to redefine the term “healthy” as a nutrient content claim, food manufacturers can continue to use the term “healthy” on foods that meet the current regulatory definition. FDA is also issuing a guidance document stating that FDA does not intend to enforce the regulatory requirements for products that use the term if certain criteria described in the guidance document are met.

If I correctly understand the meaning of “does not intend to enforce the regulatory requirements,” the FDA, while waiting for your comments, will allow manufacturers to call products “healthy” as long as the products:

(1) Predominantly contain mono and polyunsaturated fats regardless of total fat content; or

(2) Contain at least ten percent of the Daily Value (DV) per serving of potassium or vitamin D.

In other words, if your food product is made with a low saturated fat oil and contains potassium or vitamin D, it is by definition “healthy.”

Correction, September 29: An FDA official wrote to say that I didn’t quite get this right.  

Actually, if a food exceeds the low fat requirement currently in our definition, we will not take any enforcement or compliance action as long as the food meets all of the other requirements in the definition, namely that it is low in saturated fat, cannot exceed the specified levels of cholesterol and sodium, and contains at least 10 percent of the daily value for beneficial nutrients.  

Second, we are not saying that foods must contain potassium or vitamin D to be labeled as “healthy.”  We are simply indicating that potassium and vitamin D can be substituted for the beneficial nutrients now listed in the current regulations, in line with the new Nutrition Facts label regulations.

My apologies to the FDA for misunderstanding the notice.

The FDA’s request is good news for KIND bars.

But it smacks of “nutritionism”—the use of these two single nutrients (as well as others on the short list of beneficial nutrients) as indicators of quality in processed food products (and don’t get me started on vitamin D, which is a hormone, not a vitamin, and best obtained by getting outside in the sun once in a while).

Understand: this effort is not about semantics; it is about marketing.

Would you like to weigh in on what you think qualifies a food as “healthy?”  Here’s how:

McDonald’s joins the food movement???

McDonald’s ran a full-page ad in yesterday’s New York Times:*

“At McDonald’s we’re on a journey: What’s important to you is important to us.”

The ad says McDonald’s is taking these actions [with my comments]:

  • Removed artificial preservatives from Chicken McNuggets and other items [Fine, but no big deal in my book.]
  • Removed high fructose corn syrup from hamburger buns [And replaced it with what?  Sugar?  This matters? I’m guessing the price of HFCS must be close enough to the price of sugar to make this possible.]**
  • Committed to only source chickens that have not been treated with antibiotics [OK.  Now we’re talking important.  For this alone,  McDonald’s deserves high praise.  My only question: by when?]*** 

The ad also summarizes the company’s additional actions, done and promised:

  • Burgers are 100% beef
  • Eggs are freshly cracked
  • Salads feature baby spinach, kale, Tuscan red leaf lettuce, and carrots
  • Buttermilk chicken uses real buttermilk
  • Milk is sourced from cows not treated with rbST
  • 2 billion sides of fruit were served (including 59 million clementines)
  • Espresso beans are Rainforest Alliance Certified
  • Eggs will be cage-free by 2025

Amazing, no?

It’s worth a field trip to see how all this works in practice.  I’m on it.

Additions, corrections, and updates

*Jill Cornish writes that the ad also appeared in the Washington Post.

**I get a Bingo for this one.  Martijn Katan writes: “The price of beet sugar fell below that of HCFS in April 2015. By June 2016, 1 lb of HFCS-55 cost $0.412 as opposed to $0.297 for beet sugar.”  He even sends a reference: www.cornnaturally.com/Economics-of-HFCS/price-calculator.aspx

***Andy Smith points out that “In 2015, McDonald’s announced that it would stop buying chicken raised with non-therapeutic, medically-important antibiotics by 2017– but a few weeks ago announced that it had already done so.”  He too provides a reference: See QSR. “McDonald’s Eliminates Antibiotics From Its Chicken,” QSR Magazine, August 2, 2016.

Guest blog for Scientific American: the new food label

The FDA’s new rules for food labeling are finally here

The changes are a step toward better health and less obesity, especially in children

By Marion Nestle on May 24, 2016

The FDA’s announcement of final rules for its overhaul of labels on food packages is a signature accomplishment of Michelle Obama’s Let’s Move! campaign to end childhood obesity within a generation.

In 2010, in setting the agenda for Let’s Move!, the White House Task Force on Childhood Obesity called for improving the clarity, accuracy, and consistency of food package labels to enable parents and children to make healthier food choices.  The Task Force noted that more than half the adult public used food labels to decide what to buy, but that the current labels had hardly changed since the FDA’s regulations of 1993.

The FDA actually began work on revising the food label in 2005 with a request for public input on updating serving sizes, and it began formal rulemaking in 2008.  The FDA proposed rules and issued its last call for comments in 2014.

I attribute this nine-year process to details and politics.

First, the details. The Federal Register notice on the food label takes up 943 pages, and it takes another 170 pages to explain the changes in serving sizes.

FDA’s fact sheet on the changes explains the politics.  Most changes are relatively uncontroversial: the greater emphasis on calories, the removal of calories from fat, the requirement for “dual column” labels for “per serving” and “per package,” the updating of serving sizes to more closely reflect actual intake, and the rewording of the Daily Value footnote.  As Michelle Obama put it, ”you will no longer need a microscope, a calculator, or a degree in nutrition to figure out whether the food you’re buying is actually good for our kids.  So that’s a phenomenal achievement.”

Indeed it is, especially in light of a political climate in which the food industry and Congress do all they can to undermine public health measures in school food and child nutrition programs.

Mrs. Obama alluded to the ongoing political controversy: “most important of all, this label will tell you how much sugar in your snack was added during processing, and how much of it comes from ingredients like fruit.”

The new food label distinguishes between intrinsic sugars in food and those added in manufacturing; it also sets a Daily Value for the maximum amount of sugars recommended for diets of 2,000 calories a day.  I credit the Center for Science in the Public Interest for this accomplishment; it petitioned FDA for these changes in 2013 (its first added sugar petition was in 1999).

The Washington Post got right to the core of the controversy: “Why the sugar industry hates the FDA’s new Nutrition Facts label.” Americans consume roughly twice the amount of sugar recommended for good health, and sugars are rampant in processed foods.  All it takes is one 16-ounce soft drink to reach the 50-gram daily maximum.

The Sugar Association, the trade group for producers of sugar cane and sugar beets invokes science as the reason for its intense opposition: “We are concerned that the ruling sets a dangerous precedent that is not grounded in science, and could actually deter us from our shared goal of a healthier America.”

The Association argues, correctly, that the sugars that occur naturally in fruits are biochemically identical to those added in manufacturing.  But this argument misses how added sugars dilute the nutritional value of food products.  Much research supports the health benefits of eating fruit, whereas added sugars raise risks for obesity and other chronic conditions.

The Sugar Association does not really care about science.  It cares about what will happen to sales if people read labels and reject products with added sugars.  This, of course, is one of the purposes of Added Sugars on food labels.

The Association has reason to worry.  Since 1999, per capita consumption of sugars has fallen in the United States, although it still exceeds the 10 percent of calories recommended by the World Health Organization last year.  The new label should accelerate that downward trend.

An even greater worry is that labeling added sugars might encourage manufacturers to reduce the amounts in their products.  The FDA’s listing of trans-fatty acids on food labels in 2006 led to an immediate reductionin the use of hydrogenated oils as ingredients in food products.  I expect to see grams of sugars decline by the time these rules take effect in May 2018 (small food producers get until May 2019).

I see the new label as a political win for public health and Let’s Move!  But let’s keep this in perspective.  Healthful diets are based on foods, not food products.  We would all be healthier eating foods that do not come with Nutrition Facts panels, and saving most of those that do for once-in-a-while occasions.

Food-Navigator-USA’s Special Edition on Organics

This is one of Food Navigator-USA’s special editions in which this industry-focused newsletter collects several of its posts on particular topics—in this case, organics.

But first, take a look at the USDA’s summary of trends in organic food sales:

Special Edition: Where next for organics?

According to the Organic Trade Association, organic sales increased from $3.6 billion in 1997 to over $39 billion in 2014. But can the meteoric growth continue? And will organic ultimately replace the more nebulous ‘all-natural’ as consumers increasingly look for claims that are underpinned by consistent standards?
