Regular cane sugar (sucrose) is made of two-sugar molecules bound tightly together -- glucose and fructose in equal amounts. The enzymes in your digestive tract must break down the sucrose into glucose and fructose, which are then absorbed into the body.

HFCS also consists of glucose and fructose, not in a 50-50 ratio, but a 55-45 fructose to glucose ratio in an unbound form. Fructose is sweeter than glucose. And HFCS is cheaper than sugar because of the government farm bill corn subsidies. Products with HFCS are sweeter and cheaper than products made with cane sugar. This allowed for the average soda size to balloon from eight ounces to 20 ounces with little financial costs to manufacturers, but great human costs of increased obesity, diabetes and chronic disease.

Now back to biochemistry. Since there is there is no chemical bond between them, no digestion is required, so they are more rapidly absorbed into your blood stream. Fructose goes right to the liver and triggers lipogenesis (the production of fats like triglycerides and cholesterol). This is why it is the major cause of liver damage in this country and causes a condition called "fatty liver," which affects 70 million people. The rapidly absorbed glucose triggers big spikes in insulin -- our body's major fat storage hormone. Both of these features of HFCS lead to increased metabolic disturbances that drive increases in appetite, weight gain, diabetes, heart disease, cancer, dementia and more.

But there was one more thing I learned during lunch with Dr. Bruce Ames. Research done by his group at the Children's Hospital Oakland Research Institute found that free fructose from HFCS requires more energy to be absorbed by the gut and soaks up two phosphorous molecules from ATP (our body's energy source). This depletes the energy fuel source or ATP in our gut required to maintain the integrity of our intestinal lining.
