<P> Prior to the development of the worldwide sugar industry, dietary fructose was limited to only a few items . Milk, meats, and most vegetables, the staples of many early diets, have no fructose, and only 5--10% fructose by weight is found in fruits such as grapes, apples, and blueberries . Most traditional dried fruits, however, contain about 50% fructose . From 1970 to 2000, there was a 25% increase in "added sugars" in the U.S. After being classified as generally recognized as safe (GRAS) by the U.S. Food and Drug Administration in 1976, HFCS began to replace sucrose as the main sweetener of soft drinks in the United States . At the same time, rates of obesity rose . That correlation, in combination with laboratory research and epidemiological studies that suggested a link between consuming large amounts of fructose and changes to various proxy health measures, including elevated blood triglycerides, size and type of low - density lipoproteins, uric acid levels, and weight, raised concerns about health effects of HFCS itself . </P> <P> In the U.S., sugar tariffs and quotas keep imported sugar at up to twice the global price since 1797, while subsidies to corn growers cheapen the primary ingredient in HFCS, corn . Industrial users looking for cheaper replacements rapidly adopted HFCS in the 1970s . </P> <P> HFCS is easier to handle than granulated sucrose, although some sucrose is transported as solution . Unlike sucrose, HFCS cannot be hydrolyzed, but the free fructose in HFCS may produce hydroxymethylfurfural when stored at high temperatures; these differences are most prominent in acidic beverages . Soft drink makers such as Coca - Cola and Pepsi continue to use sugar in other nations but transitioned to HFCS for U.S. markets in 1980 before completely switching over in 1984 . Large corporations, such as Archer Daniels Midland, lobby for the continuation of government corn subsidies . </P> <P> Consumption of HFCS in the U.S. has declined since it peaked at 37.5 lb (17.0 kg) per person in 1999 . The average American consumed approximately 27.1 lb (12.3 kg) of HFCS in 2012, versus 39.0 lb (17.7 kg) of refined cane and beet sugar . This decrease in domestic consumption of HFCS resulted in a push in exporting of the product . In 2014, exports of HFCS were valued at $436 million, a decrease of 21% in one year, with Mexico receiving about 75% of the export volume . </P>
