Fructose & Glucose Differences

Taken from a Dr. Mercola article today:

Fructose is Metabolized to Fat

The digestive and absorptive processes for glucose and fructose are different. Unlike the glucose in other sugars, which the body uses, fructose is a relatively unregulated source of fuel for the liver to convert to fat and cholesterol. Fructose converts to fat more than any other sugar. It is also known to raise triglycerides significantly.

Most Fructose is Consumed as a Liquid

The fact that most fructose is consumed in a liquid form -- as soda -- significantly magnifies its negative metabolic effects.

Fructose Does Not Stimulate Insulin Secretion

Unlike glucose, fructose does not stimulate insulin secretion or enhance leptin, a hormone thought to be involved in appetite regulation, production. Because insulin and leptin act as key signals in regulating how much food you eat and body weight, this suggests that dietary fructose may contribute to increased food intake and weight gain.

Fructose Has no Enzymes, Vitamins or Minerals

Fructose has no enzymes, vitamins or minerals so it takes micronutrients from the body while it assimilates itself for use. However, eating a small piece of whole fruit, which contains natural fructose, is not likely to be a problem for most people -- because fresh fruits contain the enzymes, vitamins and minerals that are needed for the fructose to assimilate in the body.
