High Fructose Corn Syrup

Before we get to high fructose corn syrup (HFCS), we will take a look at two other frequently used sweeteners, dextrose and maltodextrin.

Dextrose

Dextrose is more or less an industry term for glucose. Glucose isthe most prevalent sugar in the human and the only molecule that the brain can metabolize. Dextrose is refined from corn starch. It has a very high glycemic index (no surprise since it is glucose) and while it contains no fructose, it is still a simple sugar that is very readily absorbed. It is not as dangerous as sucrose but it still is a highly processed product that should be avoided.

Maltodextrin

Maltodextrin is also a refined product usually made from either corn or potatoes. It is multiple glucose units somewhat loosely hooked together (a polymer). Because the bonds between the glucose units are very weak, it is also very readily absorbed and has a very high glycemic index. Like dextrose it should be avoided as much as possible. It has been called a "sugar substitute"but that is based on a rather strict definition of sugar as "sucrose." It is a very common additive and I have found it in many packaged foods, including potato chips.

High Fructose Corn Syrup

High fructose corn syrup is made by treating corn (which is usually genetically modified corn) with a variety of enzymes, some of which are also genetically modified, to first extract the sugar glucose and then convert some of it into fructose, since fructose tastes sweeter than glucose. The end result is a mixture of 55% fructose and 45% glucose, that is called "high fructose corn syrup." Improvements in production occurred in the 1980's making it cheaper than most other sweeteners. I remember in the 1980's when the price of Pepsi dropped from about $3 for a sixpack to about $1.50. In 1966 refined sugar such as sucrose was the was the leading sweetener / additive. In 2001 corn sweeteners accounted for 55% of the sweetener market. Consumption of high fructose corn syrup went from zero in 1966 to 62.6 pounds per person in 2001. A 12 ounce soda can contain as much as 13 teaspoons of sugar in the form of high fructose corn syrup.

Once again, the dangerous combination: fructose and glucose.

When high fructose corn syrup breaks down in the intestine, we once again find near equal amounts of glucose and fructose entering the bloodstream. As covered in recent newsletters, the fructose short-circuits the glycolytic pathway for glucose. This leads to all the problems associated with sucrose. In addition, HFCS seems to be generating a few of its own problems, epidemic obesity being one of them. Fructose does not stimulate insulin production and also fails to increase "leptin" production, a hormone produced by the body's fat cells. Both of these act to turn off the appetite and control body weight. Also, fructose does not suppress ghrelin, a hormone that works to increase hunger. This interesting work is being done by Peter Havel at UC Davis.

Some of the problems associated with high fructose corn syrup:

Increased LDL's (the bad lipoprotein) leading to increasedrisk of heart disease.

Altered Magnesium balance leading to increased osteoporosis.

Increased risk of Adult Onset Diabetes Mellitus.

Fructose has no enzymes or vitamins thus robbing the body ofprecious micro-nutrients.

Fructose interacts with birth control pills and can elevateinsulin levels in women on the pill.

Accelerated aging.

Fructose inhibits copper metabolism leading to a deficiencyof copper, which can cause increased bone fragility, anemia, ischemic heart disease and defective connective tissue formation among others.

The list below is from The San Francisco Chronicle February 18, 2004

"How much is too much?

The list below shows how much sugar, mostly in the form of high fructose corn syrup, is in each of these single servings.

Sunkist soda: 10 1/2 teaspoons of sugar

Berkeley Farms low-fat yogurt with fruit: 10 teaspoons of sugar

Mott's applesauce: 5 teaspoons of sugar

Slim-Fast chocolate cookie dough meal bar: 5 teaspoons of sugar

1 tablespoon ketchup: 1 teaspoon of sugar

Hansen's Super Vita orange-carrot Smoothie: 10 teaspoons of sugar"

Today's health tip:

Cut down or stop any food or drink with high fructose corn syrup.

High fructose corn syrup is made from genetically modified corn treated with genetically modified enzymes.

Stop or limit all foods with either dextrose or maltodextrin.

Once again, read all your food labels carefully.

Consumption of the limited amounts of fructose that occur in fresh whole organic fruit is not a problem.

Women know more about men's health than men do themselves and that's a fact. Why is that? Is it because we find it hard to discuss these things? Is it because it's not macho! From the time that we are young, we are taught that boys have to act tough and shouldn't cry. You must have heard the saying "Big Boys don't cry!"

Most of us carry this thought process into adulthood and feel by showing concern for our health, it will be seen as a male weakness. I am guilty of that myself.

I know when my prostate troubles began, I knew absolutely nothing about the prostate. I was one of the 96%. Mainly because it didn't cross my mind that I'd ever have any problems.

In addition, the prostate is in a "private" area, and it wasn't something I wanted to examine. Many people, including myself, feel uncomfortable talking about the prostate, since the gland plays a role in both sex and urination.

I have had prostate troubles, survived a cancer scare and watched my sister die from Cancer. Believe me, when I say that when you think you are going to die, it concentrates your mind on what is really important. Suddenly your priorities get focused.

Due to my prostate troubles, I became interested in learning about the prostate and how it affected my health.

I cried the day they took a biopsy and I cried with relief the day I was told it was benign. I cried many times as I watched my sister die.

I got so frustrated having to get up every night 3-4 times due to my prostate troubles and then finding I couldn't get back to sleep.

What is prostate cancer?

Prostate Cancer develops by the growth of cancerous cells within the prostate gland. Prostate cancer occurs when some of the cells that make up the prostate gland escape from the normal controls on their growth and start to divide, grow and spread in an uncontrolled manner. In its advanced form, it can produce the same symptoms as BPH. (Benign Prostatic Hyperplasia)

Warning Signs

Early prostate cancer often does not cause symptoms. When symptoms of prostate cancer do occur, they may include some of the following problems:

A need to urinate frequently, especially at night; Difficulty starting urination or holding back urine; Inability to urinate; Weak or interrupted flow of urine; Painful or burning urination; Painful ejaculation; Blood in urine or semen; and/or Frequent pain or stiffness in the lower back, hips, or upper thighs.

Any of these symptoms may be caused by cancer or by other, less serious health problems, such as BPH or an infection (Prostatitis). Only a doctor can tell the cause. A man who has symptoms like these should see his family doctor . Do not wait to feel pain; early prostate cancer does not cause pain.

These are two other main prostate problems

1) BPH - (Benign Prostatic Hyperplasia) is the abnormal growth of benign prostate cells. In an enlarged prostate , the prostate grows larger and pushes against the urethra and bladder, blocking the normal flow of urine. BPH is often the result of prostatitis.

2) Prostatitis refers to prostate inflammation and infection, which can be brief or long-lasting, mild or severe symptoms can include frequent, urgent and painful urination, erectile problems or pain >during ejaculation.

Prostatitis is rampant in the US, affecting at least 80% of American men. Most is without major symptoms. Prostate enlargement, called Benign Prostatic Hypertrophy (BPH) is often the result of prostatitis.

Treatment for Prostate Cancer

The treatment given for prostate cancer depends on how advanced or widespread the disease is. If the cancer is small and only present within the prostate gland, it is possible to treat it with

surgery (radical prostatectomy) radiotherapy (either external beam radiotherapy or brachytherapy) hormone therapy
