CHICAGO (AP) -- Many packaged meals and snacks for toddlers contain worrisome amounts of salt and sugar, potentially creating an early taste for foods that may contribute to obesity and other health risks, according to a new government study.About seven in 10 toddler dinners studied contained too much salt, and most cereal bars, breakfast pastries and snacks for infants and toddlers contained extra sugars, according to the study by researchers at the federal Centers for Disease Control and Prevention. They advise parents to read food labels carefully and select healthier choices.The researchers analyzed package information and labels for more than 1,000 foods marketed for infants and toddlers. Results appear in the journal Pediatrics on Monday.The study notes that almost one in four U.S. children ages 2 to 5 are overweight or obese - and that almost 80 percent of kids ages 1 to 3 exceed the recommended maximum level of daily salt, which is 1,500 milligrams. Excess sugar and salt can contribute to obesity and elevated blood pressure even in childhood, but also later on.\We also know that about one in nine children have blood pressure above the normal range for their age
