(CNN) – Hispanics are one of the fastest growing ethnic groups in the United States.  By the year 2050, the U.S. Census Bureau projects Hispanics will compose 30 percent of the population.  Most are Mexican-American.  A new government study drills down on the changing way Mexican-Americans adults are eating and its effect on their health.

Researchers at the National Center for Health Statistics compared statistics from 1982-1984 and 1999-2006.

Among the findings:

• Obesity is up.  In the early 1980s 21% of Mexican Americans were obese.  By the middle of the last decade, the number had climbed to close to 35%.

• More Mexican-Americans also have diabetes.  Close to 14% have it now - versus just under 10% 25 years ago.

• The group’s consumption of carbs is also up from just under 46% in the 1980s to just over 51%.
