U.S. adults, particularly Hispanics, are eating fewer fruits and vegetables and engaging in less healthy behaviors, a Gallup poll indicates. May typically begins the four strongest months of the year in overall healthy behaviors, but this year, Americans\' health habits did not increase in May and are worse compared with 2010. The Gallup-Healthways Well-Being Index, which tracks U.S. via daily interviews of no fewer than 1,000 adults, indicates Hispanics and young adults are the least likely to eat fruits and vegetables frequently. However, produce consumption was down among seniors and women as well. The Americans\' Healthy Behaviors Index score was 63.8 in May, down from 65.2 in May of last year. Respondents were asked if they ate healthy all day \"yesterday\" and on how many days they consumed five or more servings of fruits and vegetables in the last seven days. Fewer Americans reported eating healthily in May this year than did so last year, 66.2 percent versus 68.2 percent. The survey has a margin of error of 0.6 percentage points.
