Most Americans are concerned with their weight and are changing their food choices. Although losing weight remains a key priority for most adults, a surprising number of consumers are now less concerned about the amount of food they eat than they were a few years ago.

If these statements sound contradictory to you, it is because they are. Both food manufacturers and the health-care industry try hard to make sense of America’s eating habits. Not a week goes by without another survey reporting the discovery of new trends in consumers’ behavior. The picture is anything but clear.

It is true that many more Americans have become interested in healthy eating. Concerns about food safety have definitely increased, and for good reasons. In response to several outbreaks of food-related illnesses in recent years, there is now greater demand for organic food products, even if it means paying higher prices. But for most of the population, nutritional quality is still not a priority when it comes to food choices.

Most Americans don’t eat enough fresh fruits and vegetables according to the U. S. Department of Agriculture (USDA), which recommends five servings of each in its dietary guidelines. Milk and eggs are being consumed in lesser amounts, but cheese is more popular than ever. Meat, poultry and fish consumption continues to rise. The overall fat content in the average American diet is undiminished.

Americans love their snacks. According to USDA studies, almost 20 percent of daily calorie supply comes from snack food in this country. Half of younger adults skip breakfast on most days, a quarter goes without lunch and home-cooked dinners are becoming the exception rather than the rule, even among families with young children.

Kids especially suffer in growing numbers from malnutrition and weight problems due to unhealthy eating patterns.

Working men and women eat on average 25 percent of their meals away from home, but that doesn’t mean the other 75 percent are being made from scratch. Fast food, pizza, take-outs and frozen dinners are the preferred choices of those with busy lifestyles.

Pre-packaged meals, so-called “convenience foods,” became available in the 1950s, when women started to enter the work force in large numbers and being a full-time homemaker was no longer attractive or financially feasible.

The invention of the microwave, the omnipresence of fast-food chains and a growing appetite for cheap food to go all fed into these trends and continue to do so.

While many aspects of these lifestyle changes are positive, the downsides are quite devastating. We are in the midst of a national obesity epidemic that has reached crisis level. Childhood obesity has become, by far, the greatest health threat to the country’s future.

And yet, there is growing evidence that Americans are getting fed up with dieting and weight loss. Finding themselves ceaselessly barraged with often-contradictory information and expert advice, people become less enlightened and instead more confused and helpless. Others feel increasingly resentful about being lectured on what they see as their private business.

As important as good health may be to them, many Americans find it too arduous and time-consuming to follow suit in their diet.

The number of people who say they watch their food intake at least occasionally for weight management and fitness purposes is stagnant, according to reports by three leading weight-loss companies.

“People are just saying, ‘The hell with it. I’m going to eat whatever I feel like,’” said one spokesperson for Marketdata Enterprises, a research firm specializing in data gathering for the weight-loss market.

According to a survey conducted by the American Dietetic Association, more than 80 percent of Americans now rate nutrition as “only moderately important” to them.

Most experts agree that people are clearly moving away from being obsessed with being thin. Some have suggested that the aging baby boomers are at least one of the reasons: When folks get older, they are more set in their ways, which is also reflected in their eating habits.

“I think there is some cultural backlash to our societal urge to live forever,” said John Lyons, a psychologist at Northwestern University. “It’s like a realization of one’s limits and an acceptance, something you see in the 40s-to-50s age group. Maybe you just accept your lot and do the best you can.”

Not surprisingly, support groups for overweight people are emerging all over the country. Demand for better protection of the rights of the obese is getting louder and keeps gathering followers. Obesity has been stigmatized for far too long in our society, they say, and it’s time to question what counts as the ideal body image.
