(AXcess News) Washington - A recent study by the University of Hawaii's, department of Geology and Geophysics, shows that the main ingredient in fast food Americans are eating is corn.  The problem is there's no requirement in the US to disclose the ingredients in fast foods, says Dr. Hope Jahren, who lead the study.

The Study, published in the latest edition of Proceedings of the National Academy of Sciences (PNAS) notes that $100 billion is spent annually by Americans on fast food and that the amount of both meat and calories consumed within the U.S. diet is 'disproportionate', according to Dr. Jahren.

In that Abstract, Dr. Jahren notes that the amount of corn found in french fries, beef and chicken - through those animals diets or in the case of french fries, through cooking oil - made up the bulk of those fast food ingredients.  Worse, fertilizer use was also evident when applied in heavy concentrations on certain field crops fit for animal feed (you guessed it, corn).

"Our results highlighted the overwhelming importance of corn agriculture within virtually every aspect of fast food manufacture," Dr. Jahren notes in his report.

The study noted that the level of isotopes identifying corn 'varied significantly' amongst restaurants' french fries, depending on the chain.  Wendy's clearly used only corn oil, whereas McDonald's and Burger King favored other vegetable oils. "This differed from ingredient reports," notes the Study's Abstract.
