High Fructose and Obesity

popsicle Soda is soda and a pop is a Popsicle in NYC, where I used to live. But when I moved to Kenton, Ohio at the tender age of 7, I ordered an orange pop but got an orange soda instead. The confused worker at the Dairy Freeze told me, “You ordered an orange pop, so drink it!” He thought I was just off the boat and gave me a scowl (something I would experience quite often in Ohio).

I told my neighbors about this, and they said, “No, you’re drinking pop.” I immediately turned in my application to move back to NYC, but my parents rejected it. Okay, fine. Soda is pop, pop is Popsicle, and aunt is pronounced “ant.” See if I care.

Well, I did care and refused to call soda “pop.” And my brother and I drank so much soda while growing up that I’m surprised out heads didn’t “pop” off. Can soda make you unhealthy and obese?

High-fructose corn syrup is in practically everything that is sweet nowadays. I was a Child of the Corn, sans the axe, growing up in Kenton, but I never predicted it would be added to so many foods! Fructose is naturally found in fruit and honey-that’s right, darling.

Initially, fructose was studied for its benefits, like not utilizing insulin in its metabolism. A revolution for diabetics!? Low doses work well with the liver to prevent high blood sugars. But as with everything, too much of a good thing turns sweet to sour.

High dose fructose is associated with Metabolic Syndrome X: insulin resistance (leading to glucose intolerance and Type II Diabetes Mellitus), poor cholesterol, increased body fat, and hypertension.

High fructose interferes with the insulin so that muscles don’t utilize sugar well. So the sugars go straight to fat or cholesterol. (Do not pass Go. Do not collect $200.) The Nurses’ Health Study of 1999 showed high fructose was associated with increased C-peptide levels (serum insulin levels are above normal all day long).

In mice, high fructose causes fat collections to increase like Marlon Brando’s later-in-life belly. And we all know that increased fat can cause high blood pressure, high cholesterol levels, and diabetes.

Three’s Company star Suzanne Somers said, “Sugar is the enemy,” which is true in some respects. Sucrose is what most people use as table sugar– two glucose sugar molecules. Fructose is a different type of simple sugar but doesn’t sate (satisfy) your appetite like glucose does. Animal studies have shown that they will eat less food sweetened with sucrose, but will eat like Jabba the Hut at a buffet with food containing high fructose. Maybe that’s why all these snacks and drinks that are sweetened with high-fructose corn syrup turn some people into Jaws.

I’ve always heard the folklore about children, “Oh, she just ate a bunch of sugar, so she is bouncing off the walls.”

I’ve never been a believer in that, but high fructose actually stimulates the sympathetic nervous system to give a high-as well as to increase insulin resistance.

Obesity as well as the use of high-fructose corn syrup has been increasing in the past two to three decades. In my practice, I see a lot of overweight and obese patients with 20-oz bottles of high-fructose-sweetened drinks under their arm. (I wonder if I can add to my “No Smoking” sign, “No high fructose”?) Giving up a bottle of sugared drinks, like sweetened tea, can help a person lose 10-20 pounds in a year. I’ve seen it work!

I drink too much diet soda, which probably isn’t good for me, but it’s my alternative to high fructose. Sometimes a spoonful of sugar does not make the medicine go down. Sorry if that sounds corny.

  1. Wow! I knew too much sugared drinks wasn’t good for you but I didn’t realize it put that much weight on a person. So I guess I should slack of the McDonalds famous sweet ice tea? So how much sugar in a bottle juice is too much? I guess to get myself in order I need to start drinking homemade fruit juices after I get another juicer.

  2. I have had patients who drank a 12oz soda or 12oz sweet tea a day - when they gave them up they lost 10-20 pounds in a year without even trying. Bottled juice that is not 100% juice has added sugar or fructose normally. A standard serving of say orange juice is <8 oz.

  3. It was intresting to read about pop and soda. I’m from Elyria Ohio and ran in to the same thing when I visited New Jersry as a child. I agree with you about sweetners but what about soy? My wife cannot eat soy and it’s even in vitamins.

  4. Elyria? I heard of Elvira (sp?) because I think my school used to compete with them.
    I’m Asian, of course I love soy! Sounds like she has an allergy though. I’ll have to write an article on soy allergies - though I don’t think it is to common. Let’s see.

  5. Heya Dr. Hong,

    Have you heard anything about the new diet Pepsi? I don’t drink much pop at all, but noticed this at the store — it’s aspartame, and acesulfame potassium; that’s supposed to work with the aspartame to intensify the sweetness. It also has an amino acid, phenylalanine. It’s seems like its somewhere between pop and an energy drink, except it comes in a 2 ltr instead of a $3 dixie cup. The only reason I noticed it is because it was available in Europe when I lived over there a long time back, but just came on the U.S. market this past year.

  6. The famous author LOST has blogged me? By the way, your book is really very good and intelligent. So to your question - no I have not heard about the new Diet Pepsi and the acesulfame K+. I’m curious to learn more about it. I hope it doesn’t like a 3rd eye to grow or something
