High fructose corn syrup (HFCS)
High fructose corn syrup (HFCS) is a sweetener derived from cornstarch, created through a chemical process that converts some glucose into fructose. It is distinct from table sugar (sucrose) which contains equal parts glucose and fructose. HFCS gained widespread popularity in the United States during the 1980s, primarily due to economic advantages, as corn prices fell due to agricultural subsidies, making HFCS a cheaper alternative to cane sugar. This shift led to a significant increase in HFCS consumption, aligning with rising obesity and diabetes rates, which have sparked debate among experts regarding a potential link between these health trends and HFCS intake.
Despite extensive discussions, no definitive conclusion has been reached about the health implications of HFCS, leading to a market shift towards beverages sweetened with cane sugar. Critics of HFCS have raised concerns about its higher fructose content and its potential effects on appetite regulation and overall health. Furthermore, the Corn Refiners Association's attempt to rebrand HFCS as "corn sugar" was rejected by the FDA to avoid misleading consumers. Recent studies have explored HFCS's connections to various health issues, including cancer, yet the results remain inconclusive. Consumption of HFCS has been on a decline in recent years, reflecting evolving consumer preferences and health consciousness.

High fructose corn syrup (HFCS)
High fructose corn syrup (HFCS) is a chemically modified sugary substance used as a sweetener in many food and beverage products. HFCS is not table sugar; table sugar (scientifically known as sucrose) consists of an equal balance of two simpler sugars, glucose and fructose, whose molecules have bonded. HFCS is manufactured in laboratories by converting cornstarch into syrup, which is then engineered to transform some glucose into fructose. HFCS is frequently used in place of sucrose as a flavored sweetener in soft drinks, fruit juices, cereal, yogurt, pasta sauce, peanut butter, and ketchup. Since the early 2000s, medical experts and scientists have debated the health effects of HFCS consumption.
Overview
HFCS was first produced in 1957, although it did not come into significant use until the 1980s, when it gradually replaced table sugar as the most common sweetener used in food products. The shift from sucrose to HFCS in the United States was largely driven by economic factors. Namely, the price of sugar was increasing while government subsidies to the agricultural industry dramatically lowered the price of corn. This allowed food and beverage manufacturers to generate greater profits without increasing prices by substituting low-priced HFCS for higher-priced sucrose. Coca-Cola switched to HFCS in 1980; Pepsi followed suit shortly thereafter. During the twenty-year period between 1970 and 1990, consumption of HFCS in the United States increased more than 1,000 percent.
The rates of obesity and diabetes in the United States have increased exponentially since HFCS came into widespread use, causing some scholars and health experts to question whether these trends were connected to consumption of HFCS. By 2013, no definitive scientific answer had been reached one way or the other, even as the debate between representatives of the table sugar and corn industries continued. Because of the ongoing and often contentious debate, carbonated, "natural" beverages sweetened with pure cane sugar (and not HFCS) became popular among the public.
Fueling the discussion were anti-HFCS activists who claimed HFCS was connected to weight gain and that consumption of HFCS increased a person’s risk for developing diabetes. This negative publicity led the Corn Refiners Association, an organization of HFCS producers, to lobby the Food and Drug Administration (FDA) to switch the name of their product to corn sugar. The FDA rejected this proposal in May 2012, claiming that calling HRCS "corn sugar" would mislead consumers and could pose health risks to people who have adverse reactions to fructose. Critics of the Corn Refiners Association’s bid for a name change concurred with the FDA and added that such a move would imply that HFCS is a natural substance, when in fact it can only be manufactured, not grown.
A 2010 study conducted by medical researchers at the University of Southern California revealed that the HFCS in Coca-Cola, Pepsi, and Sprite drinks contained significantly higher levels of fructose than was previously thought, at a ratio of approximately 65 percent fructose to 35 percent glucose. Some experts have claimed that fructose prevents the body from producing leptin, a hormone that sends signals to the brain when the body is no longer hungry. Thus, some contend that higher levels of HFCS consumption leads individuals to overeat, which may be driving the growing obesity and diabetes rates in the United States. A 2012 joint study conducted by researchers at the University of Southern California and the University of Oxford that examined HFCS consumption patterns in forty-two countries found that nations in which HFCS was frequently consumed had diabetes rates that were 20 percent higher than nations in which HFCS was rarely or never consumed. The Corn Refiners Association criticized the validity of the study, however, claiming that the research did not prove that HFCS was the direct cause of the diabetes.
The US Department of Agriculture (USDA) reported in 2023 that the average per capita consumption of HFCS has decreased steadily between 1999, when it was 65.9 pounds, and 2021, when it was 39.5 pounds. In 2024, one National Institutes of Health research study suggested that fructose could accelerate the growth of cancerous tumors, but the study could not determine whether HFCS was causing cancer rates to increase.
