I have heard there is a link between eating that and obesity. Should I eliminate it from my diet if I am trying to lose weight? It is in everything–ketchup, bread, mayo and other processed food. Should I go on the non-processed food diet?
Prior to 1996, high-fructose corn syrup (HFCS) was virtually non-existent in Americans’ diets. When it came to sweeteners, the number one version on the market was sucrose, or table sugar. But that all changed after the invention of high-fructose corn syrup.
Made from corn starch through a complicated process, HFCS emerged as a cheaper, significantly sweeter, easy to transport and easy to use (especially in beverages, since it’s a liquid) alternative to sugar.
Whereas regular corn syrup is all glucose, HFCS is composed of half glucose and half fructose.
Fructose is absorbed differently [than other sugars]. It doesn’t register in the body metabolically the same way that glucose does.
When glucose is consumed, a set of reactions occur in the body allowing it to be used as energy, and production of leptin, a hormone that helps control appetite and fat storage, is increased.
When fructose is consumed, however, it appears to behave more like fat with respect to the hormones involved in body weight regulation. Fructose doesn’t stimulate insulin secretion. It doesn’t increase leptin production or suppress production of ghrelin. That suggests that consuming a lot of fructose, like consuming too much fat, could contribute to weight gain.
The first thing to do is to give up all soft drinks and other sweetened beverages that contain it. Then start checking labels meticulously. Even products that aren’t thought of as "sweet’ often contain it
Fortunately, as more and more consumers opt to stay away from HFCS, there are product alternatives out there. Organic pasta sauce and ketchup, for instance, are much less likely to contain HFCS than regular varieties.
