Compared to sugar, high-fructose corn syrup (HFCS) is worse for your health

Regular table sugar, or sucrose, (also called cane sugar) is made of equal parts of two simpler sugars, glucose and fructose. When digested, it immediately breaks down into these two components and that’s what your body absorbs: glucose and fructose. HFCS has the exact same constituents in a slightly different proportion: the most common HFCS, used in soft drinks, contains 55% fructose and 45% glucose (hence, high fructose). So, ingesting HFCS instead of table sugar gives you a wee bit more fructose and a wee bit less glucose. Big whoop. To listen to some people, HFCS is the end of civilization as we know it! Yet, many studies have been conducted comparing HFCS to table sugar, and they have failed to turn up any real difference in their effects on the body, including insulin, triglycerides, blood glucose, or appetite-related hormones.

The HFCS alarmists also overlook two interesting facts:

  • The most common type of HFCS, called HFCS 55 because it contains 55% fructose, is used primarily in soft drinks, and it is supposedly evil because it contains too much fructose. Yet, there is also HFCS 42, used in some beverages, baked goods, and processed foods) which contains 42% fructose and 53% glucose – more glucose than fructose. Somehow they are both equally evil, according to the alarmists, one because it contains too much fructose and the other because it contains – what, too little fructose? Oh please!
  • Honey, beloved of health food fans, contains more fructose, relative to glucose, than the worst HFCS – 38% fructose and 31% glucose, approximately. I don’t recall hearing about any anti-honey campaigns, do you?

This does not mean that HFCS is good for you! It just means that it is no worse than cane sugar. More and more evidence indicates that the problems with sugar are not the type of sugar you eat, but the amount. Overdoing it on organic honey is just as bad as eating too much of any other source of sugar.

What about taste? Some people claim that soft drinks made with cane sugar taste better than the HFCS versions, and they’ll go to great lengths to get it, such as driving to Canada to buy cane sugar Coke. I can’t tell the difference, but perhaps some people can.
