High-fructose corn syrup versus table sugar.

Overall, Americans consume too much addedNUTRITION FACTS LABEL sugars from a variety of sources. By reducing the amount of sugar you consume, you will protect your immune system – which in turn will protect you from developing a wide variety of chronic diseases. The damaging effect of too much sugar in the diet contributes to weight gain, diabetes, impaired immune system and chronic diseases.

High-fructose corn syrup is a corn-based sweetener. It’s almost an equal blend of glucose and fructose and can be bought only by food manufacturers. The use of high-fructose corn syrup increased greatly around 1975 because of its low cost, and in the ensuing years it has replaced sucrose as the primary sweetener in processed foods.

High-fructose corn syrup and table sugar (sucrose) are similar in chemical composition. Both products are used as sweeteners. Both contain fructose and glucose and are metabolized in a similar way by the body. Each contributes the same amount of energy (four calories per gram or 16 calories per teaspoon).

Rather than basing all the focus on which sweetener is better or worse, it’s more important to know how to identify the amount of sugar found in, or added to foods. You must also consider your own dietary needs and restrictions by discussing with your physician.
