Consumer Education Remains a Challenge in Sodium Reduction

Wednesday, June 27th, 2012

Despite the food industry’s concerted efforts in the last few years to reduce sodium in foods, consumers still have many misconceptions about sodium’s impact on health. As moderator John Ruff, IFT President-Elect, said in his introduction to the “Stimulating Sodium Reduction and Overcoming Technological Challenges” late-breaking session held Wednesday morning, June 27, only 50% of consumers are aware of the link between sodium and high blood pressure. With 31% of deaths in America caused by cardiovascular diseases and the majority of Americans consuming way more than the recommended daily intake of sodium, it is apparent that the challenge to educate consumers is a vital one.

Part of this education needs to entail communicating with consumers about where the majority of their sodium is coming from. According to Ruff, 77% of sodium comes from processed foods, and only 11% comes from cooking and adding salt at the dinner table. However, when consumers think about making an effort to cut down on their sodium, they often forgo the salt shaker at meal time. In addition, “consumers think that salty snacks are the main source of sodium in their diets,” said Ruff, “when in reality, out of processed foods, breads contain the most sodium.”

There are obvious and known challenges to decreasing sodium in such processed foods. As MaryAnne Drake, North Carolina State Univ., explained to attendees, salt is a very functional ingredient in food products. It provides microbial stability, structure/texture, and flavor. And with salty taste being a main driver of liking, reformulating products to lower sodium needs to be done cautiously. “The products have to taste good and similar to their traditional full-sodium counterparts,” explained Drake.

“Very few consumers are willing to give up taste for health benefits,” said Barbara Davis, Health Focus International. In fact, even when faced with a serious illness or heart-related disease, only 17% are willing to sacrifice taste for health. Davis went on to say that in order to drive home the point that consumers need to reduce their sodium intake, the messaging need to be relevant to them. And sometimes, this is not a health message. For example, while 37% of women respond to medically driven concerns surrounding sodium, almost as many (26%) respond more to concerns over sodium causing bloating and water weight gain.

Davis also believes that instituting a new method for labeling sodium on food packaging might help consumers keep tabs on their daily allotment. “Milligrams don’t mean much to consumers when they are looking at the Nutrition Facts Panel,” said Davis. She proposes a point system for sodium, in which one point would be equal to 100 mg of sodium. Similar to the Weight Watchers Points program, consumers would know that, if they are healthy, they should consume 23 points or under a day, and if they are at risk, they would have 15 points/day.

So obviously there are still hurdles to overcome for the food industry to market low-sodium foods and have them accepted by consumers. However, it is clear we are moving in the right direction. “More than 50% of consumers say that reduced-sodium products taste better than they used to,” said Davis. And as Ruff said in his introduction, a step-wise approach to modifying food products is necessary in order for consumers to get used to lower levels of sodium in foods.

The Bacteria in Beef That ‘Don’t Behave’

Tuesday, June 26th, 2012

BY DAVID DESPAIN

Beef producers have become quite successful at detecting and preventing contamination of E. coli 0157:h7 in their raw beef products—that’s thanks to years of experience after the Shiga toxin-producing bacterial strain (STEC) was first declared as an adulterant in raw beef in 1994.

However, the USDA Food Safety and Inspection Service (FSIS) has now expanded the adulterant list to include six non-0157 strains (026, 045, 0103, 0111, 0121, and 0145). The new rule had producers and scientists at the IFT Annual Meeting on Tuesday, June 26, warning that these bacteria “don’t behave” like you’d want them to.

“With 0157, we’ve had years and years of testing. We haven’t had those years of experience in the lab with these,” said food safety and public health professor Mindy Brashears of Texas Tech University.

The rule, in place as of June 4, 2012, (an extension from March 5, 2012), was in response to an October 2009 citizen’s petition. According to research microbiologist Christopher Sommers, the petition came after recent outbreaks and a CDC study that showed that these “big six” accounted for more than 70% of non-0157 STEC infections from 1983 to 2002.

A couple of companies—Costco and Beef Products Inc. (BPI)—already have food safety systems in place for non-0157 STEC strains. Director of food safety and quality assurance at BPI, Craig Letch, said that the company developed a system using “robust sampling” (n=167) and has spent well “over a million dollars” in outsourcing 100% of the testing for non-0157 STEC strains. Costco Wholesale’s program for testing for non-0157 STEC strains has been in place since June 2010, according to director of food safety and quality assurance Christine Summers.

“Obviously, we don’t want to make any of our customers sick,” she said, noting that the company produces about 160 million pounds of ground beef annually.

However, she added that there are problems with the rule. “There is a diversity of STECS. It would be beneficial to identify the virulence genes that cause human illness. Knowledge needs to be gathered.”

Despite challenges, Brashears is optimistic that the methodologies are sure to continue to improve as testing progresses and more baseline data is collected. Ultimately, she said, interventions pre- and post-harvest will be key to reducing STECs and protecting the beef supply. 

The FSIS has issued methodology for detecting the “big six” at www.fsis.usda.gov/PDF/mlg_5b_02.pdf.

Changing the Conversation About Food Science

Tuesday, June 26th, 2012

It’s no secret that food science and processed foods are under fire on many fronts—by activists, marketers, and consumers themselves. To figure out ways to help change that situation, a group of Annual Meeting attendees gathered Tuesday afternoon for a workshop session titled “The Scapegoat That Is Food Science: How Do We Save the Discipline That Is Feeding the World?”

Presenters including Fergus Clydesdale of the University of Massachusetts and Guy Johnson of Johnson Nutrition Solutions helped set the stage for the conversation.

“From my perspective, I think we have a crisis on our hands with respect to food science,” said Johnson.  “Food science is being skewered not only by consumers, but by people who should know better—people in the academic community, people in the research community. We really need to do something about it.”   

“We’re getting attacked with emotionalism, and we’re responding with facts, and it isn’t working,” said Clydesdale.

Author Michael Pollan, an outspoken critic of processed foods, says that “food is what your great-grandparents ate,” said Clydesdale, adding that he hopes that is not the case because what our grandparents ate wasn’t always optimal. Consider Ireland in the mid-19th century, for example; when the potato blight struck, millions died or were forced to emigrate.

“I really think the media should look at just how good were the good old days,” said Clydesdale. “We have to approach it on an historical level with real data.” He pointed out that many people today are losing touch with some of the benefits of food science because they’ve rarely encountered a spoiled food and “therefore they don’t understand how a food stays stable and safe and why they should be concerned about it.”

After hearing opening remarks, session attendees divided up into groups to brainstorm strategies for helping to improve the image of food science. Participants came up with a long list of suggestions, including those that follow.

• Build messages around the culinary aspects of food science because consumers are favorably inclined to celebrity chefs.

• Think about using universities to disseminate information that consumers will perceive as credible and unbiased.

• Work on finding ways to communicate scientific data in ways that target consumers’ emotions.

• Help consumers realize that most food is processed in one way or another.

• Attempt to attract a growing pool of students to the food science discipline, and educate their parents about the potential for careers in food science.

Taylor Wallace of the Council for Responsible Nutrition wrapped up the session with a few thoughts and recommendations. “We really have to rally as a scientific community,” said Wallace. He acknowledged that communicating scientific information is complex because “science is gray; it’s hardly ever black and white.” He stressed that “consistent communication to consumers” is critical. “We need to seek common ground. How can we get aligned with consumers if we can’t get aligned ourselves?”

IFT Kicks Off Campaign to Counter Misconceptions about Food Science

Tuesday, June 26th, 2012

The Institute of Food Technologists (IFT) today launched a new public education  campaign called ”A World Without Food Science” (www.worldwithoutfoodscience.org) that will aim to generate greater awareness of the role food science plays in ensuring a nutritious, safe and abundant food supply. The campaign is a multimedia, national initiative featuring a series of videos that highlight how food science has responded to major food issues and provided positive solutions on a global scale.

The overarching kick-off video, unveiled during the keynote session at IFT’s Annual Meeting & Food Expo in Las Vegas, accurately depicts what a grocery store would be like without the existence of food science. The black and white footage shows empty shelves, rotten fruit, insect-infested grain and spoiled meat to show the realities of a world without food science. The scene changes to color when the voiceover explains how dedicated food science professionals make it possible to have food that is safe, flavorful and nutritious. The concepts of the video are based on an IFT scientific review titled “Feeding the World Today and Tomorrow: The Importance of Food Science and Technology” published in the peer-reviewed journal, Comprehensive Reviews in Food Science and Food Safety.

The campaign also includes five separate video segments that feature interviews with experts from various food science disciplines to show the positive impact of food science on the public. The first two video segments of the series were presented during the keynote address at the IFT’s Annual Meeting & Food Expo. The first video highlights the challenges surrounding availability of food and how we will need to feed approximately 9 billion people by 2050. The second video focuses on food safety and the important role of food science in ensuring that the food we eat is safe.

“As a scientific society, education is at the core of our mission as we advance the science of food. It’s especially important for the public to understand where their food comes from,” said IFT President Roger Clemens, DrPh. “This campaign tells the story of food science in a new visual way so that consumers understand the role of food science in their daily lives.”

In addition to consumer education, another goal of this campaign is to reach and inspire students to pursue food science careers. Food science incorporates concepts from many different fields including microbiology, chemical engineering, biochemistry and more. The ever-expanding field of food science encompasses a wide range of careers in areas such as food production and processing, quality assurance and control, food product development, food science research, and regulation and enforcement of food laws. IFT.org has information on becoming a food scientist, as well as lesson plans and activities for teachers.  IFT also produced the Day in the Life of Food Scientist videos to help people understand what it’s like to walk in the shoes of a NASA food scientist, a product developer at Disney Consumer Products, and a food packaging professional at a multinational food packaging and processing company.

As part of the World Without Food Science campaign, three more videos will be released within the year. Topics include Nutrition, Environmentally Responsible Food Production, and Developing Food Products for Specific Populations. Each video will be distributed nationwide and featured along with facts and additional resources on www.worldwithoutfoodscience.org. The videos complement IFT Food Facts, a multimedia website created to show the practical applications of food science for consumers, such as food safety in the farmer’s market, how to store leftovers and understanding expiration dates. For more information, please visit iftfoodfacts.org for more information.

This video campaign was produced thanks to funding from the following IFT Divisions—Product Development, Quality Assurance, Citrus, Food Microbiology, Nutraceuticals, and Refrigerated & Frozen Foods.

Science News Gets to the Point

Monday, June 25th, 2012

Today’s media sources cover more than just politics, crime, civic events, and sports; developments in food and consumer issues receive daily coverage as well. But how can the food profession ensure that the information reporters distribute and consumers receive is credible, accurate, and current? In Session 060, “Beyond Published Results: The Importance of Communicating Science,” speakers will provide guidelines and tips for communicating science to the media. During this session, food professionals can learn how news stories are generated and how news and information get transferred. Speakers will also discuss translating technical information for non-technical audiences, the best way to market research to influential stakeholders, and preparing for media interviews.

What makes food science news resonate with the public? What is the fine line between a story being too scientific (i.e., boring) or being trendy yet factually incorrect? Speakers David Schmidt, Robert Gravani, and Catherine Adams-Hutt will analyze various approaches to convey factual information about food and food science by examining examples of media successes and failures and analyzing stories for factual integrity and pop appeal on Tuesday, June 26, at 1:30 p.m. in room N208.

Dr. Regina Benjamin Defines a Role for Food Science

Monday, June 13th, 2011

by Toni Tarver

Dr. Regina Benjamin at IFT11For the Beacon Lecture series on Monday, June 13, Dr. Regina Benjamin, U.S. Surgeon General, laid out her goal for the health and wellness of U.S. citizens. Food science and the food industry play significant roles in her vision. “As America’s doctor, I really want to provide the best scientific knowledge” to make the lifestyles of Americans healthier, she said. And the best time to provide that knowledge is before illness strikes: a strategy for prevention. Food is an important part of this strategy, and Dr. Benjamin emphasized the role that the food industry can play in the prevention of food-related disease.

Dr. Regina Benjamin and Dr. Robert Gravani at IFT11The U.S. Dept. of Agriculture’s MyPlate icon emphasizes the dietary elements necessary for a healthy lifestyle: at least half a plate of fresh fruits and vegetables. “We are working on getting fresh produce into neighborhoods where there are no grocery stores,” Dr. Benjamin said. And as part of the First Lady Michelle Obama’s Let’s Move campaign, several food companies—including The Coca Cola Company, ConAgra, Kellogg Company, and Kraft Foods—have committed to trim 1.5 trillion calories from their food products by 2015. The food industry can also direct their efforts to offering more healthy food products that mirror the 2010 Dietary Guidelines for Americans.  These endeavors will ensure that consumers have the tools necessary to make healthier lifestyle choices that can lead to healthier lives.

While the role of the food industry is significant, perhaps that of the medical industry is even more important. “We need to move from a system based on [treating illness] to one of preventing illness,” Dr. Benjamin said. This may mean changing the curriculum at medical schools so that it includes more courses on food science and nutrition. Hopefully, once physicians, food scientists, and food manufacturers are armed with the same information, consumers will gain more access to resources for maintaining good health and preventing food-related diseases.

Food Science & Technology Under Attack

Monday, June 13th, 2011

The promise of a better future through technology was a major theme of the original television series Star Trek in the 1960s. However, this philosophy is seemingly being rejected and replaced by the wistfulness of another 60s TV show “Green Acres.” Gentleman farmer Oliver and space scientist Mr. Spock are not simply television characters; they represent the opposing issues in the current debates on food technology. For nearly 40 years, many of the most significant technological advances in food science and technology (e.g., biotechnology, irradiation, fortification, packaging, artificial sweeteners, and nanotechnology) have met and continue to be hindered by a lack of consumer acceptance. The public is being led to believe that the food industry deals in a sea of toxic chemicals that are causing everything from cancer to obesity. Public policy on health and foods is often made in an environment where science-based evidence takes a back seat. Members of professional societies like IFT need to realize that every negative headline undercuts public trust in their profession; every politically expedient decision lessens public confidence in science; and every hyperbolic claim weakens the credibility of scientists.

On Tuesday morning from 8:30–10:00 am in Room 292, Session 228 Star Trek or Green Acres: The Future Roles of Chemistry and Technology in the Food Industry, Regulatory Policy, and Human Health: Part 1 – Where Are We and How Did We Get Here? will examine the evidence of how the public views science and scientists. The session will include discussions on the consequences of public attitudes (particularly on the acceptance of new food ingredients, processes, and technologies) and how scientists and professional societies can change negative attitudes into positive outcomes.

Part 2 (Session 257) of this symposium will subsequently take place from 10:30 am–12:00 pm in Room 292.

Clemens to Food Scientists: Make a Difference

Saturday, June 11th, 2011

by Mary Ellen Kuhn

Roger ClemensSpeaking Saturday night, June 11, at the Awards Celebration, IFT President-Elect Roger Clemens called on food scientists to help build a better, more nutritious food supply—for consumers in the United States and throughout the world.

“Our mission to supply safe, abundant nutritional food should compel us to develop ideas and strategies to reconcile the U.S. food supply with the Dietary Guidelines for Americans,” said Clemens.

“There are many products that we can develop using whole grains, less sugar, and seasonings other than salt, while assuring a safe and nutritious food supply. Consumer demand is moving away from shelf-stable products, so perhaps we need to reduce our focus on extending shelf life and allocate more attention to maintaining freshness,” he suggested.

As a member of the 2010 Dietary Guidelines Advisory Committee, Clemens was instrumental in supplying science-based recommendations to help shape the guidelines.

“As scientists, we have significant roles to play here,” said Clemens. For example, he pointed out that “we have the opportunity to use science to help bridge the gap between what the Dietary Guidelines recommend and the amount of fresh produce available. We can enhance existing technologies such as vertical farming, hydroponics, and aeroponics or develop new ones to increase our capacity to grow, harvest, and deliver fresh produce.”

Clemens also turned his attention to the state of Americans’ diet and health, noting that there has been an “alarming increase in the number of people with health problems linked to poor dietary choices and lifestyles.”

While the basic approach to a healthier lifestyle is fairly straightforward—eating well, maintaining a healthy weight, and getting adequate exercise—the process of developing dietary recommendations that work for everyone can be complicated. Clemens noted, for example, that “if consumers skip or limit eggs, milk, and butter to avoid saturated fat and cholesterol, they end up with insufficient intakes of choline and vitamin D and numerous other nutrients. … Those consequences could contribute to significant public health issues, particularly among populations at risk.”

Clemens also raised another major challenge confronting those charged with improving Americans’ collective public health. “Healthy food is not nutritious unless it is eaten,” he said. “Clearly, getting consumers to make healthier food choices requires more than issuing new recommendations every five years, putting up a website, and placing healthier choices on the shelves of supermarkets.”

To this end, he noted, “as a follow-up to the release of the Dietary Guidelines, IFT has recommended that we initiate a multi-disciplinary dialogue among key stakeholders from academia, government, and industry, to identify potentially effective interventions to enhance short- and long-term weight management, better understand what drives food behaviors and behavioral economics, and assess the impact of time allocation and constraints as related to food choices.”

Clemens brought his remarks to a close with words of thanks and tribute to the members of IFT. “You membership and volunteerism ensure the strength and relevancy of this organization,” he said. “Our collective expertise makes us the premier authority in food science and technology. Our knowledge makes us the best individuals to ensure that our food resources are capable of meeting current and future Dietary Guidelines, and that we continue to provide a safe and abundant food supply worldwide.”

An International Collaborative Approach to Food Science

Saturday, June 11th, 2011

by Toni Tarver

Finding solutions to complex issues is often more productive with collaboration. Consequently, the link between food safety and nutritional quality can benefit greatly from a global cooperative approach. Session 066 Internationalization of Food Science Education and Research through Collaboration Across Academia, Industry, and Government will describe how the two issues can be addressed effectively through unified global approaches to improving education and targeted research. Speakers from the United States and China will discuss topics related to this cooperative effort. Jian Chen of Jiangnan University will discuss the world-renowned food science program at Jiangnan University and its cooperative programs with U.S. institutions of higher learning. Perry Ng of Michigan State University will present creative ways to develop dual-degree food science programs between the United States and China. Pingfan Rao will discuss specific collaborative efforts between major Chinese universities and multinational food companies. Bruce Hamaker of Purdue University will cover the recruitment efforts to attract international food science students. And Hongda Chen of the National Institute of Food and Agriculture will discuss the U.S. Dept. of Agriculture’s cooperative strategies with China for food science research and education. Session 066 will be on Sunday, June 12, from 1:30-3:00 pm in room 398.

Michael Specter to Defend Science

Saturday, June 11th, 2011

by Mary Ellen Kuhn

Michael SpecterHis book is titled Denialism, but there’s no denying that when New Yorker writer Michael Specter takes the stage during the Annual Meeting Keynote Session on Sunday morning, June 12, his presentation promises to be provocative.

A former New York Times correspondent, Specter writes frequently about science, technology, and public health. In his book, he argues that too many consumers are adopting anti-science attitudes, rejecting childhood vaccines and genetically modified foods, for example, while rushing to embrace organic foods, dietary supplements, and natural cures. Repudiating scientific inquiry—or embracing “denialism”—takes us down a dangerous path, Specter contends, and it gets in the way of global priorities like eliminating famine and preventing the spread of dangerous diseases.

Denialism book coverThe book’s subtitle—“How Irrational Thinking Hinders Scientific Progress, Harms the Planet, and Threatens Our Lives”—further clarifies Specter’s position. Americans’ mounting suspicion of science stems from a variety of causes, Specter theorizes. These include our poor grasp of history and the difficulty of accepting a reality that used to be taken for granted: that some risk is an inevitable accompaniment to progress.

In addition to his keynote address, Specter will participate in a panel discussion with leading food industry experts on the topic, “Delivering Food Science: Changing the Image of Food Science in the Marketplace.” Martin Cole, Chief of CSIRO Food and Nutritional Sciences, and Mary K. Wagner, Senior Vice President, Global Research & Development, Starbucks Coffee Co., will also take part in that discussion. Linda Eatherton, Partner, Director Global Food & Nutrition, Ketchum, will moderate the conversation.

The Keynote Session, which will take place Sunday from 8:30–10:15 a.m. in the La Nouvelle Ballroom of the Morial Convention Center, will also feature remarks by Executive Vice President Barbara Byrd Keenan, IFT President Bob Gravani, and Martha Rhodes Roberts, Chair, Feeding Tomorrow. A year-in-review video and presentation of the IFT Food Expo Awards are also on the agenda for Sunday morning. The session is sponsored by the Corn Refiners Association.
