Starting next month, the country's No. 3 soft drink company plans to roll out 10-calorie versions of five of its biggest soda brands: 7-Up, Sunkist, Canada Dry, RC Cola and A&W Root Beer. The drinks are an extension of Dr Pepper Ten, which was launched last year as a better-tasting alternative for men who don't like the image or taste of diet soda. But the new 10-calories sodas are being marketed to both men and women. Unlike traditional diet sodas that use only artificial sweeteners and have zero calories, Dr Pepper Snapple Group Inc. says its 10-calorie sweetener mix has just enough high-fructose corn syrup to overcome any reservations people might have about the weak or cloying taste of diet drinks. And by taking away most the calories â¿¿ a can of regular typically has about 150 calories â¿¿ the company is washing away much of the guilt. ___ FedEx says it can grow by cutting costs NEW YORK (AP) â¿¿ FedEx may be pessimistic about the U.S. economy, but it's confident about growing its earnings. The world's second-largest package delivery company, a bellwether for economic health because of the vast number and kinds of shipments it handles, lowered its economic forecast for the U.S., saying there remains a lot of uncertainty for the country. FedEx maintained its earnings forecast for the full fiscal year ending in May, counting on a massive cost reduction plan and a slightly more optimistic view of growth overseas. Shares rose $2.06, or 2.2 percent, to $94.42 in afternoon trading, even though its forecast for the current quarter, which includes the critical holiday season, falls short of Wall Street expectations.
