An elevated level of fructose, caused by the digestion of refined sugar and high-fructose corn syrup, is much more insidious than previously believed. It appears to be the root cause of a majority of cancers and other major chronic diseases such as heart disease, obesity, and type 2 diabetes.
To understand what it means to have an “elevated level” of fructose, it will be helpful for you to review “Do Not Try to Drink From a Fire Hose! (click to review), which describes what it means to have an elevated level of glucose in the bloodstream.
This post, Stop Insulin Resistance and Stop Cancer, describes what happens when too much fructose enters the bloodstream too quickly.
It is important to clarify that an elevated level of fructose from refined sugars is the villain, not fructose sugar itself.
The fructose sugar in fruits gives the fruit its sweet taste. Natural fruits, along with vegetables, provide valuable nutrients for our health. Major health authorities, such as the American Heart Association, the American Institute for Cancer Research, and the American Cancer Society, advise us to eat plenty of fruits and vegetables every day. They speak with one voice with this advice.
Fruits and vegetables have relatively small amounts of fructose that most bodies can handle quite well.
Fructose sugar is not a problem.
The presence of fructose can be compared to snowflakes or a light blanket of snow; they are refreshing. It is the avalanche that destroys. It is a high level of fructose in the bloodstream that destroys.
When fructose arrives in the bloodstream with volume and velocity, as it does in the digestion of refined sugars, that is when it does its damage. When too much fructose enters the liver, the liver cannot process it fast enough for the body to use it as sugar.
White refined sugar and high-fructose corn syrup are simple sugars composed of glucose bonded to fructose.
Glucose and fructose have different chemical structures and are metabolized differently. Therein lies the reason that fructose is singularly harmful.
Glucose is metabolized by the cells of the body. Our bodies are designed to run on the energy provided by glucose.
Fructose is metabolized by the liver. When you eat a plum, or an apple, or any fruit that is in its natural state, the liver receives the fructose from that fruit at a slow, steady rate. It is the speed with which the liver has to do its work that will affect how it metabolizes fructose.
It is certain; when too much fructose hits the liver too quickly, the liver will convert most of it to triglycerides – fat!
Researchers who study the mechanisms of insulin resistance now believe that insulin resistance is caused by the accumulation of fat in the liver. Marvin T. Samuel, M.D., who studies insulin resistance at Yale School of Medicine says: “when you deposit fat in the liver, that’s when you become insulin resistant.”
For glucose to enter the cells of the body, insulin must bind to the insulin receptors on the target cell and signal the cell to absorb the glucose. “The accumulation of fat in key tissues activates proteins that interfere with the insulin signal pathway. Thus, if there’s too much fat in the liver,”
explains Dr. Samuel, “the ability of insulin to activate those signals is impaired, making those cells resistant to insulin.”
Too much fructose consumption can lead to excess fat accumulation in the liver. This activates proteins that block insulin signaling.
What is the cause and what is the effect?
Excess Fructose………. causes……… Fat Accumulation in the Liver; then,
Fat Accumulation in the Liver.… causes……… Insulin Resistance; then,
Insulin Resistance…………….…causes………,Obesity, Heart Disease, and Cancer.
Excess fructose is the root cause.
Here Is the Good News.
If you want to eliminate insulin resistance and all that comes with it – particularly cancer growth and the higher risk of cancer recurrence – eliminate the cause. When refined sugar was eliminated from the diet of laboratory animals, the liver fat went away.
According to study results presented at the 2006 meeting of the American Diabetes Association, half of all Americans will develop insulin resistance, increasing their risk of developing diabetes, heart disease, and cancer. This condition is often reversed! Diet and exercise are the best ways to reverse insulin resistance.
