The Pros: HFCS is responsible for the increase in body mass of Americans
High fructose Corn Syrup (HFCS), is a sweetener commonly found in processed foods, beverages and other food products in the United States. Its use has increased dramatically in recent years, coinciding with a rise in obesity rates in the U.S. (Bray, Nielsen, & Poplin, 2004). The evidence supports the idea that HFCS plays a role in the increase in body weight among Americans.
Bray et.al. Bray and colleagues (2004) concluded that drinking HFCS in beverages is associated with an increased body weight, body mass index (BMI), and more body fat in adults as well as children. Study results suggested that fructose in HFCS could cause weight gain by increasing appetite and altering metabolism.
Also, foods high in calories, but low in nutrition value like sodas, sweets, and baked goods, are likely to contain HFCS. These foods are often cheaper and more accessible than healthier options, making them a more appealing choice for individuals on a limited budget (Goran & Tappy, 2006).
Although there could be many other contributing factors to rising obesity rates in the U.S. there is strong evidence that high HFCS intake is one of them. Strategies that reduce the consumption of HFCS and provide access to more healthy food choices may help to lower obesity rates in the U.S.
