The underlying etiological causes of obesity, whether behavioral, environmental, genetic, or a combination of several of them, have not been completely elucidated. The obesity epidemic has been attributed to the ready availability, abundance, and overconsumption of high-energy content food. We determined here by Pearson¡s correlation the relationship between food type consumption and rising obesity using the loss-adjusted food availability data from the United States Department of Agriculture (USDA) Economic Research Services (ERS) as well as the obesity prevalence data from the Behavioral Risk Factor Surveillance System (BRFSS) and the National Health and Nutrition Examination Survey (NHANES) at the Centers for Disease Control and Prevention (CDC). Our analysis showed that total calorie intake and consumption of high fructose corn syrup (HFCS) did not correlate with rising obesity trends. Intake of other major food types, including chicken, dairy fats, salad and cooking oils, and cheese also did not correlate with obesity trends. However, our results surprisingly revealed that consumption of corn products correlated with rising obesity and was independent of gender and race/ethnicity among population dynamics in the U.S. Therefore, we were able to demonstrate a novel link between the consumption of corn products and rising obesity trends that has not been previously attributed to the obesity epidemic. This correlation coincides with the introduction of bioengineered corns into the human food chain, thus raising a new hypothesis that should be tested in molecular and animal models of obesity. Key Words: Obesity, food trend, corn product, genetically modified, bioengineered Introduction 11) It is estimated that, worldwide, approximately 937 million adults are overweight and 396 million are obese . This rising trend continues unabated both globally and in the United States, which claims the largest population of overweight and obese adults [2,3]. Various etiologic factors associated with obesity have been reported, including a number of genes identified from genome-wide scans and functional genomic studies as well as some viruses and bacteria [4-7]. The current prevailing hypothesis centers on the premise that the problem of obesity is one of energy imbalance, wherein total energy intake far exceeds energy output . In addition, the global epidemic of obesity has been attributed to heuristic observations of an increase in the...
