In a weighty issue, just who tips the scales?

A profit-conscious food industry, lagging medical science and consumer indiscipline may be adding to our pounds.

Published March 19, 2006

It's tempting to blame big food companies for America's big obesity problem.

After all, they're the folks who Supersized our fries, family-portioned our potato chips and Big Gulped our sodas. There's also the billions they've spent keeping their products ever on our minds and in our mouths.

Likened by some to the way tobacco companies seduced smokers, such practices have made the food industry the target of lawsuits and legislation seeking to yank junk food from schools and curb advertising to children. But some experts say neither the problem nor the solution is nearly so simple.

"You don't have the collusion or the cover-up you had in smoking," said James Tillotson, a business and food policy professor at Tufts' Friedman School of Nutrition. "We want to blame somebody, but the thing is, we're all a part of it."

Sure, companies set the stage with cheap, calorie-dense foods.

But government also has propped up agribusiness, the medical community was slow to take on obesity and good nutrition, and consumers seem determined to move less and eat more, said Tillotson, a former food industry executive.

How much of that burden of blame belongs to the food industry can be difficult to answer.

Personal responsibility

The food industry emerged at a time when malnutrition was the nation's chief dietary concern. But at some point food became too plentiful, a change that altered the culture of the American diet.

Yale obesity expert Dr. David Katz says that's because companies aggressively peddle food to people who don't need it.

Food industry officials prefer to call it consumer choice. "We don't think the food industry has done anything particularly wrong in this regard," said Robert Earl of the Food Products Association, a lobbying group that prefers to indict sedentary lifestyles and poor choices.

Companies have tried to help people make better choices, he says, offering healthier products and more nutrition data. But people can't be forced to make the right choice and consumer disinterest doomed many of those products.

He's right. Consumers bear much responsibility for their weight and that two-thirds of Americans are overweight or obese. It's not the industry's fault that people don't get exercise, or that schools have cut physical education, or that people prefer the taste of Twinkies (500-million sold a year) to tofu (much less).

But some critics say Earl's assessment is disingenuous. Personal responsibility has limits in the face of a multibillion-dollar marketing whirlwind pushing countless high-calorie treats, they contend.

"They (food companies) are putting $36-billion into directing those choices," said Marion Nestle, a nutrition professor at New York University and critic of the food industry. "And their methods are very effective."

Meanwhile, efforts to market the healthier products Earl spoke of historically have been lackluster, acknowledges Brock Leach, an executive for new products at PepsiCo Inc.

As for nutrition data, it isn't always helpful. And attempts to standardize or clarify labeling still meet resistance.

Personal responsibility also falters when it comes to children, who are bombarded by junk food ads that can undermine parents. Everything from child-friendly merchandising of sugary cereals to cartoon ads is designed to give companies more sway over what children eat, said Dr. Susan Lynch, a child obesity doctor and wife of New Hampshire Gov. John Lynch.

Such tactics make it tougher to teach good eating habits to kids who equate food with entertainment, she said. "It becomes a marketing thing, a fashion thing," Lynch said. "You want to buy the food with the cartoons on the box or the toy."

The industry should have done more to direct the child obesity debate, agrees Pepsi's Leach. Much of the focus has been on getting junk food out of school vending machines, but Leach said that's just a tiny part of the solution.

He says food companies - including his own, one of the biggest losers in the vending machine fight - should have offered healthier vending options long ago, then redirected attention to other critical issues, such as getting physical education back in schools.

Science lag

In many ways the food industry is chasing a moving target. For years, food production was a better understood science than nutrition. And so whole grains were abandoned and hydrogenated fats embraced.

The medical community takes much of the blame, said Dr. George Blackburn of Harvard Medical School's nutrition division.

"We didn't even put nutrition in the medical curriculum except in the last 30 or 40 years," he said. "As soon as we got drugs, to hell with nutrition. We're just now getting it to be a professional responsibility to be sensitive to people's healthy eating."

Today, the food industry suffers from nutrition research overload, with tidal waves of new and sometimes contradictory health findings that strain its ability to produce appealing foods that are in sync with the latest science.

Even when companies succeed, they still are susceptible to scientific surprises that can break a business. When saturated fat was the enemy, companies reformulated their products, said Grocery Manufacturers Association spokeswoman Stephanie Childs. Only later did they learn that the trans fats they had replaced them with were even worse.

But the science lag can't explain the growing ubiquity of food or the ballooning portions of it, from bigger buckets of movie popcorn to McDonald's much vilified - and now defunct - Supersized burgers.

The industry again points to the consumer, saying that starting in the 1970s people demanded convenience and bargains. Smart companies launched family sizes and sold food everywhere from office supply chains to hardware stores.

"It's a tremendous way of getting people to buy more at lower cost to the producer," said Nestle, who said research has shown that the more food people have, the more they eat. "There's no question that that's an incentive to buy. Everybody loves a bargain."

This has changed how Americans eat. So-called portion distortion has contributed enormously to obesity. And overeating becomes even easier when food is everywhere, Nestle said. Meal time is all the time when everything from cars to backpacks to grocery carts are redesigned with snack food holders to accommodate constant munching.

But Nestle acknowledges it becomes a chicken-or-egg question. Lifestyles have changed and Americans want to eat big and on the run. Did that lead food companies to change, or did new products change Americans?

Engineering obesity?

Despite his criticism of the industry's practices, Yale's Katz acknowledges companies are in a difficult position. Ultimately, they sell food, and staying in business means selling the foods people want. Public health is secondary.

But what if those companies engineered their foods to make you eat more of them? Though he admits there is little evidence to support it, Katz said he believes companies do just that, much the way tobacco companies were accused of tinkering with nicotine. Research shows people eat more when faced with a variety of foods, or even a variety of flavors within a single food. For example, you are less likely to overeat plain baked potatoes than those drenched in butter, salt, sour cream and chives.

Sugary cereals, Katz said, have more salt in them than many potato and corn chips. Katz believes that's one way to make a cereal's flavor more complex and appealing to get people to eat more of it.

Industry officials dispute Katz's theory. Earl, of the Food Products Association, said he knows of no company that has knowingly manipulated ingredients as Katz suggests. Whatever the food industry's share of the blame, Tillotson, the Tufts professor, said obesity lawsuits are inappropriate and Congress is considering a measure to bar them. Food companies were asked to feed a hungry nation; suing now penalizes them for doing so, he said.

Industry officials say lawsuits divert resources from efforts to educate consumers and to produce healthier foods. Market demand and social responsibility are better catalysts for change, they say.

And some companies deserve real credit for living up to that.

General Mills Inc., the nation's No. 2 cereal maker, now makes all its cereals from whole-grain flour.

Kraft Foods Inc., the nation's biggest food manufacturer, says it's curbing snack food ads to children and will redesign packaging to flag its healthier products. The company also recently cut the fat in hundreds of products and stopped marketing snacks at schools.

PepsiCo Inc., which credits healthier products with two-thirds of its revenue growth, has launched various healthy eating education efforts and even has tied executive bonus programs to the development and marketing of healthier items.

The Coca-Cola Co. now labels some of its sodas with nutrition data for the entire bottle, not just one serving.

But while critics applaud the changes, they say industry goodwill and consumer demand aren't reliable enough. The realities of competition can push goodwill aside and consumers can't be counted on to want what's good for them. Leach acknowledges the industry tends to follow consumer demand, and that includes high-fat, high-sugar foods.

That's why Richard Daynard, director of the obesity and law project at Northeastern University School of Law in Boston, says lawsuits - some are pending, some were dismissed or settled - still are needed as part of a larger assessment of the obesity epidemic.

Ellen Van Gelder, an obese 41-year-old health care worker from Concord, N.H., doesn't need a lawsuit to make her diagnosis.

Though she disapproves of many of the food industry's marketing methods and wishes food companies would make it easier to eat healthier, ultimate responsibility for her weight is her own, she said.

"I would love to blame somebody else. The reality is it's each person's responsibility," said Van Gelder, who has battled her weight most of her life. "You put the food on your plate. You choose whether to eat it."
