The fructose content of the high fructose corn syrup (HFCS) used in many popular soda brands has been sorely underestimated. Around 100 years ago the average American consumed a mere 15 grams of fructose a day, primarily in the form of fruit. One hundred years later, one fourth of Americans are consuming more than 135 grams per day, largely in the form of soda.
Fructose at 15 grams a day is harmless (unless you suffer from high uric acid levels). However, at nearly 10 times that amount it becomes a major cause of obesity and nearly all chronic degenerative diseases. Instead of consisting of 55 percent fructose and 45 percent glucose, many soda brands, including Coke, Pepsi and Sprite, contain as much as 65 percent fructose, nearly 20 percent higher than originally believed.
According to one study, the mean fructose content of all 23 sodas tested was 59 percent -- higher than claimed by the industry. When you consider that Americans drink an average of 53 to 57 gallons of soda per year (depending on the source of your statistics), this difference in actual fructose content could make a huge difference in your health.
