Obesity has quickly become one of the most talked-about health problems in the United States, and the issue could have some weighty implications for the food industry. Already manufacturers are offering health-related information on their Web sites, some have altered their advertising and marketing strategies, and product innovations are coming down the pipeline that address health concerns.

Businesses serious about socially responsibility are looking for ways to address America's problem with obesity. Some companies are looking at value-added services like nutrition education, which could ultimately win shoppers' loyalty. Others have suggested creating diet- or health-related displays that are easier to find.

From a legal perspective, corporations may soon be forced to develop health-related food programs, as lawsuits over health issues are becoming prevalent. Some observers have likened the food business to the tobacco industry, which became the target of lawsuits and high taxes as smoking came to be seen as a public health threat. If the similarity between the food and tobacco industries is maintained in the courts, it is likely that the heavy regulations placed on the tobacco industry will tax the food industry as well.
