How Does High Fructose Corn Syrup Affect the Body?

High fructose corn syrup is a lab-created derivative of corn found in many processed foods, including soda, salad dressings and juice drinks. Its prevalence in our diet causes concern for how exactly the body processes this sweetener and how elevated levels of fructose can affect the body.

  1. Comparison to Sugar

    • Regular table sugar is equal parts glucose and fructose, while high fructose corn syrup is anywhere from 55 to 80 percent fructose with the remainder in glucose. The modification has chemical and hormonal effects on the body.

    Fructose and the liver

    • Fructose is only metabolized through the liver, while glucose breaks down in every cell in the body. A diet high in fructose can result in a fatty liver or even cirrhosis.

    Fructose and appetite

    • Since fructose does not go the brain or the stomach, the hormones that make you feel full (leptin and ghrelin) are not stimulated. Without feeling full, it's easy to overeat.

    Fructose and cholesterol

    • High fructose corn syrup can actually scar the internal walls of the arteries. The body produces cholesterol to heal the walls of the arteries, creating an ongoing cycle of damage to the arteries. This leads to heart damage.

    Fructose and copper

    • Fructose interferes with copper metabolism, which helps collagen and elastin production, two components of healthy, youthful-looking skin. Poor copper metabolism can affect the physical appearance of skin.

    Fructose and diabetes

    • Proven contributors to diabetes are overeating and a poor diet. Since fructose affects both areas, it can also contribute to the rise in diabetes.
