Is a serving of pasta 1 ounce or 2? Is a helping of peanut butter 1 tablespoon or twice that amount? The answers depend on whether you are reading the dietary guidelines published by the Department of THE Health and HuNUMBERS JO CRAVEN man Services MCGINTY and the Department of Agriculture online and on educational posters, or the Food and Drug Administration labels printed on food packages. They don’t match up. If that isn’t frustrating enough, the government keeps changing its mind about what constitutes healthy eating. The latest turnabout took place last month, when the Dietary Guidelines Advisory Committee declared that cholesterol and certain fats—once considered the bane of a healthy diet—aren’t so bad after all. Coffee and alcohol in moderate doses are also OK, according to the committee, whose recommendations will contribute to the 2015 Dietary Guidelines for Americans to be completed this year. Here’s a primer on what the government’s dueling servingsize numbers actually try to communicate, and why. The USDA and HHS dietary guidelines, as the name implies, aim to give consumers advice on what they should eat. They are revised every five years based on a review of the latest medical and scientific research by an advisory committee of outside experts. The resulting guidelines tell consumers how much to eat from each food group in a day to meet nutritional needs for good health. The FDA serving sizes printed on packaged foods, by contrast, are supposed to reflect how much consumers really eat, but the amounts are based on survey data collected in the late 1980s. Americans eat more than they used to, and the labels no longer accurately reflect consumer behavior. Here’s how this situation came about. Until the 1950s, USDA and HHS dietary guidelines didn’t clearly define serving sizes. In response to criticism, they developed measurements, defining a serving of fruit or vegetables as half a cup, a serving of grains as 1 ounce, and a serving of meat as 2 to 3 ounces. But visual guides published for consumers continued to express most of the recommendations as daily servings. In 1992, for example, the Food Pyramid recommended 6 to 11 servings or bread, grain or pasta each day. The problem was, people identified a serving as the amount of food on their plates, and it wasn’t clear from the pyramid that 1 serving was intended to equal 1 ounce. By that measure, about 3 cups of pasta would total 6 servings—the entire daily recommendation for many people. A half cup of pasta weighs about 1 ounce. I n 2005, the USDA and HHS dietary guidelines, seeking to end the confusion caused by the word “serving,” published new daily recommendations according to specific measurements, including ounces, cups and teaspoons, depending on the food. With this approach, the daily recommendation for bread, grain and pasta, was recorded as 6 ounces rather than 6 servings for a 2,000 calorie diet. “One muffin the size of your head, one bagel or one bowl of pasta is a 6-ounce equivalent,” said Lisa R. Young, a nutritionist and professor at New York University who stud- On Bread Alone The USDA considers 1 ounce of grain a serving—about a slice of bread—and recommends 6 ounces daily, preferably whole grain. FDA food labels allow consumers to compare the size and nutrition of slices, which vary greatly.

Fruits and vegeta- bles together cover half the plate. Protein—meat and poultry for most people—occupies less than a quarter of the space. “The plate was a huge step forward in really giving people education on what proportions are expected to come from fruit and vegetables, whole grains, and animal protein sources,” said Rafael Pérez-Es- OUTPUT Jacqueline Gonzalez of Pantropic Power recruits U.S. military veterans looking for work during a jobs fair in Miami last month.

As the unemployment rate falls, “we’re going to see a labor market that’s much stronger, which will spur wage and price growth.” The jobs figures showed Americans’ average workweek held steady at 34.6 hours for the fifth straight month. The number of hours worked is up slightly from a year ago. The job market has averaged 275,000 new jobs each month over the past year, the most since March 2000. The pace of hiring accelerated Composite Continued from Page One caveats: Wage growth remains tepid. The share of Americans working is near the lowest level since the 1970s. And more previously unemployed Americans left the labor market in February than found jobs. “There is a lot of slack left in the labor market,” said Megan Greene, chief economist at John Hancock Asset Management. “As long as you don’t have upward pressure on wages, you won’t have upward pressure on inflation.” The report showed few signs of a pickup in wages, one of the biggest missing pieces of the economic expansion. Average hourly earnings among private-sector workers last month rose 2% from a year earlier, a slightly slower year-over-year advance than January’s annual gain of 2.2%. The figure is at odds with robust hiring, but matches with strong growth in low-paid restaurant and retail jobs. Columbus Castings, an Ohio steel foundry, hired 175 workers in recent months to meet increased demand for the railway equipment it produces. The firm’s chairman, Joseph Haviv, said it has been a challenge to find workers in the Columbus region, which has an unemployment rate below 4%. But wages aren’t rising, in part because the company has expanded its search for employees to include those with criminal records and those on extended spells of unemployment, who often can’t command strong wages. “Our traditional process of hiring wasn’t working,” he said. “Our retention rate was very low.” The physically demanding foundry jobs, which start at $14 an hour, were unattractive for skilled workers. Mr. Haviv found inexperienced hires could do the job with some basic training. And by adding so many jobs at the bottom of the company’s pay scale, Columbus Castings’ average hourly wage has fallen this year. Many economists, including some Fed policy makers, expect While the overall job picture is solid, wage gains have failed to accelerate, labor-force participation remains near a three-decade low and the share of historically better-paying manufacturing jobs is sinking. 1980s ’90s 2000s ’10s THE WALL STREET JOURNAL. through most of last year, with the gains generally coinciding with better economic growth. The U.S. economy approached a 5% annual-growth pace in the second and third quarters of 2014. But output slowed to a 2.2% advance in the final three months of the year. Many economists forecast growth to have eased further early in 2015, but hiring persists. The broadly improving labor market has changed the type of job applicants seen by the Medical Weight Loss Clinic in Southfield, Mich. “People are changing jobs,” said Nick Welham, vice president at the chain of 33 clinics. He views that as a sign that workers have more leeway to look for the job they want. Hiring was strong across most industries, but particularly so in lower-paying fields. The leisure and hospitality sector added 66,000 jobs last month and retailers added 32,000 positions to payrolls. But better-paying professional and business-services firms added 51,000 jobs, despite a decline in temporary-help jobs, a typically low-paying category in the field. Manufacturers added just 8,000 jobs, the smallest seasonally adjusted gain in more than a year. That could show factories are facing headwinds from global economic turmoil and a stronger dollar. The mining category, which includes oil-and-gas extraction and related services, fell by 9,300. “The new jobs aren’t as good as the old jobs in terms of wages,” said Gary Chaison, an industrial-relations professor at Clark University in Massachusetts. “Manufacturing workers have become hamburger flippers.” The irony? Wage gains have been strongest in the lowest-paying fields. The leisure and hospitality industry, with average earnings of $14.23 an hour, saw wages grow 3.2% from a year earlier in February. Retail wages advanced 2.8%. In contrast, manufacturing pay rose just 1.3%. Those gains could support stronger consumer spending and cushion the economy from international risks. As well, a steep drop in oil prices has boosted consumers’ spending power despite modest wage gains. Evette Rowe’s hourly wage has nearly doubled to $13 an hour since she took a job in 2011 at Atwater’s, a Maryland chain of bakery cafés. She started as a dishwasher, a minimum-wage job she took after two years of unemployment. Now she’s handling invoices for the company’s production kitchen, a similar role to the office-manager job she lost at nonprofit during the recession. The additional income allowed her to purchase a used Oldsmobile and fix a leaky bathtub in her home. “I have a little more now,” the 42-year-old Baltimore resident said. “I can go to the hairdresser again and get that shirt I see in the window.” Trade Gap Shrinks Amid Cheaper Oil BY JEFFREY SPARSHOTT WASHINGTON—Cheaper U.S. energy prices and lower demand for foreign oil helped narrow the U.S. trade gap in January. The trade deficit shrank to a seasonally adjusted $41.75 billion in January, the Commerce Department said Friday, as crude imports fell. Overall, exports decreased 2.9% from December to $189.41 billion, and imports also fell 3.9% to $231.16 billion. The drop-off in both imports and exports reflects an array of factors, primarily the steep drop in crude prices, but also disruptions related to a West Coast port labor dispute, a firming dollar and the relative strength of the U.S. economy. Last month, the trade deficit for petroleum products fell to $10.69 billion, its lowest level since November 2003. Nonpetroleum imports registered at $168.99 billion on a seasonally adjusted basis, down from December’s $172.27 billion and the highest level on record.

Over time, real wages—those adjusted for inflation—are determined by productivity. Hourly wages have grown by an annual average of just 2% since the expansion began. In February, they rose just 0.1% from January, and 2% from a year earlier. Real wage growth has generally lagged behind productivity growth during the expansion. That has confounded economists and Federal Reserve officials. Most blame slack in the labor market that isn’t captured in the unemployment rate, such as the many people working part time who would like to work full time. Still, even if real wages do catch up with productivity, the scope for significant gains will be limited if productivity itself doesn’t pick up. Why has productivity performed so poorly? Faulty data may be partly to blame. Chris Varvares of Macroeconomic Advisers, a consulting firm, contends that data on workers’ hours are more accurate than data on how much they produce, and that revisions should boost both recent output and productivity. Productivity data are notoriously volatile. Both productivity and GDP were revised upward for 2013. Last year’s figures may have been depressed by unusual weather-related output losses in the first quarter. The severity of the financial crisis and recession is another possible explanation for weak productivity growth. The deep downturn may have crimped companies’ willingness to invest in the sorts of efficiency-enhancing equipment and software that raises productivity. Weak business investment has been one of the puzzles of the expansion so far. Mr. Varvares camilla, a professor at the Yale School of Public Health and a member of the Dietary Guidelines Advisory Committee. F DA food labels include nutrition information to help consumers compare similar products, but FDA serving sizes aren’t recommendations. Because the FDA’s food labels tell consumers how much they tend to eat from a bag, box or can, rather than how much they should eat, some FDA servings are double the size of those suggested by the USDA and HHS—and they are about to get bigger. The FDA is in the process of updating the labels to reflect the larger portions Americans now typically eat. When the new labels are implemented, the FDA serving size of ice cream will increase from a half cup to a full cup. The serving size for a muffin will increase from 85 grams to 110 grams. And products that are typically consumed in one sitting—a 20ounce bottle of soda, for example—will no longer be labeled as more than one serving. “That’s created some controversy,” said Mary Poos, acting director of the FDA’s Office of Nutrition, Labeling and Dietary Supplements. “Some people say we shouldn’t make them bigger because people will eat more.” estimates that capital—equipment, software and buildings— per worker has grown just 0.3% a year so far this decade, by far the worst in at least 40 years. Many new innovations are reliant on equipment and software. For example, a new computer might be necessary to take advantage of the latest computeraided design software. Thus, the reluctance to invest may have retarded the spread of innovations through the economy. If this diagnosis is correct, the best hope for a rebound in investment and productivity would be for the economic recovery to gather steam. The more confident that companies are in future sales, the more they will invest. That would elevate productivity, profits and wages, feeding back to spending in a virtuous circle. That already may have begun happening. An array of big firms ranging from Macy’s Inc. to Campbell Soup Co. have announced increases to their capital budgets. Yet the slowdown in productivity began before the recession, suggesting that more is at work than just the lingering effects of that slump on business confidence. Fifteen years ago, when the Nasdaq first topped 5000, firms were rushing to exploit the Internet with new communications and computing technology. They may not see the same potential now. In the past week, the Nasdaq returned to 5000, led by a new generation of technology stars. Its biggest, Apple Inc., has just been added to the Dow Jones Industrial Average. Many economists talk of another wave of innovations driven by consumer applications such as social media. Technology stocks are more sedate than they were 15 years ago, and high valuations of dubious business models are less common. That probably means a heart-stopping collapse isn't around the corner—nor is a return to the heady productivity growth that marked the first bubble.
