I'm sure most of you have seen those commercials recently brought to you by the Corn Refiners Association heralding the safety of high fructose corn syrup. My favorite is this one -
There are so many reasons why this commercial rules. Besides the fact that there is no way that two teenagers would be bullshitting over breakfast about the merits of high fructose corn syrup. And then the one who became indignant about it. He starts rattling off information like bullet points. I guess he has to though because the crux of the commercial is that the one kid doesn't know dick about what he's talking about and for that reason, and that reason alone HFCS has no ill effects. Love it. Anyway, if some of you out there know that HFCS isn't too good for you but feel like that idiot who didn't know dick, here is an enlightening article I found on Huffington Post. The guy gets a little heavy-handed for my tastes but the information he passes on is valuable.
Sugar Maybe Bad But This Sweetener Is Far More Deadly
By Dr. Joseph Mercola 
Study after study are taking their place in a growing lineup of  scientific research demonstrating that consuming high-fructose corn  syrup is the fastest way to trash your health. It is now known without a  doubt that sugar in your food, in all it's myriad of forms, is taking a  devastating toll. 
And fructose in any form -- including high-fructose corn syrup (HFCS)  and crystalline fructose -- is the worst of the worst!
Fructose is a major contributor to:
• Insulin resistance and obesity
• Elevated blood pressure
• Elevated triglycerides and elevated LDL
• Depletion of vitamins and minerals
• Cardiovascular disease, liver disease, cancer, arthritis and even gout
A Calorie is Not a Calorie
Glucose is the form of energy you were designed to run on. Every cell in  your body, every bacterium -- and in fact, every living thing on the  Earth--uses glucose for energy. 
If you received your fructose only from vegetables and fruits (where  it originates) as most people did a century ago, you'd consume about 15  grams per day -- a far cry from the 73 grams per day the typical  adolescent gets from sweetened drinks. In vegetables and fruits, it's  mixed in with fiber, vitamins, minerals, enzymes, and beneficial  phytonutrients, all which moderate any negative metabolic effects. 
It isn't that fructose itself is bad -- it is the MASSIVE DOSES you're  exposed to that make it dangerous. 
There are two reasons fructose is so damaging:
1. Your body metabolizes fructose in a much different way than  glucose. The entire burden of metabolizing fructose falls on your liver.
2. People are consuming fructose in enormous quantities, which has  made the negative effects much more profound. 
Today, 55 percent of sweeteners used in food and beverage  manufacturing are made from corn, and the number one source of calories in America is soda,  in the form of HFCS.
Food and beverage manufacturers began switching their sweeteners from  sucrose (table sugar) to corn syrup in the 1970s when they discovered  that HFCS was not only far cheaper to make, it's about 20 percent  sweeter than table sugar.
HFCS is either 42 percent or 55 percent fructose, and sucrose is 50  percent fructose, so it's really a wash in terms of sweetness.
Still, this switch drastically altered the average American diet. 
By USDA estimates, about one-quarter of the calories consumed by the  average American is in the form of added sugars, and most of that is  HFCS. The average Westerner consumes a staggering 142 pounds a year of sugar! And the very products  most people rely on to lose weight -- the low-fat diet foods -- are often the ones  highest in fructose.
Making matters worse, all of the fiber has been removed from these  processed foods, so there is essentially no nutritive value at all.
Fructose Metabolism Basics
Without getting into the very complex biochemistry of carbohydrate  metabolism, it is important to understand some differences about how  your body handles glucose versus fructose. I will be publishing a major  article about this in the next couple of months, which will get much  more into the details, but for our purpose here, I will just summarize  the main points. 
Dr. Robert Lustig[i] Professor of Pediatrics in the Division of  Endocrinology at the University of California, San Francisco, has been a  pioneer in decoding sugar metabolism. His work has highlighted some  major differences in how different sugars are broken down and used:
• After eating fructose, 100 percent of the metabolic burden rests on  your liver. But with glucose, your liver has to break down only 20  percent.
• Every cell in your body, including your brain, utilizes glucose.  Therefore, much of it is "burned up" immediately after you consume it.  By contrast, fructose is turned into free fatty acids (FFAs), VLDL (the  damaging form of cholesterol), and triglycerides, which get stored as  fat.
• The fatty acids created during fructose metabolism accumulate as  fat droplets in your liver and skeletal muscle tissues, causing insulin  resistance and non-alcoholic fatty liver disease (NAFLD). Insulin  resistance progresses to metabolic syndrome and type II diabetes.
• Fructose is the most lipophilic carbohydrate. In other words,  fructose converts to activated glycerol (g-3-p), which is directly used  to turn FFAs into triglycerides. The more g-3-p you have, the more fat  you store. Glucose does not do this.
• When you eat 120 calories of glucose, less than one calorie is  stored as fat. 120 calories of fructose results in 40 calories being  stored as fat. Consuming fructose is essentially consuming fat! 
• The metabolism of fructose by your liver creates a long list of  waste products and toxins, including a large amount of uric acid, which  drives up blood pressure and causes gout.
• Glucose suppresses the hunger hormone ghrelin and stimulates  leptin, which suppresses your appetite. Fructose has no effect on  ghrelin and interferes with your brain's communication with leptin,  resulting in overeating.
If anyone tries to tell you "sugar is sugar," they are way behind the  times. As you can see, there are major differences in how your body  processes each one. 
The bottom line is: fructose leads to increased belly fat, insulin  resistance and metabolic syndrome -- not to mention the long list of  chronic diseases that directly result.
Panic in the Corn Fields
As the truth comes out about HFCS, the Corn Refiners Association is scrambling to convince  you that their product is equal to table sugar, that it is "natural"  and safe.
Of course, many things are "natural" -- cocaine is natural, but you  wouldn't want to use 142 pounds of it each year.
The food and beverage industry doesn't want you to realize how truly  pervasive HFCS is in your diet -- not just from soft drinks and juices,  but also in salad dressings and condiments and virtually every processed  food. The introduction of HFCS into the Western diet in 1975 has been a  multi-billion dollar boon for the corn industry.
The FDA classifies fructose as GRAS: Generally Regarded As Safe.  Which pretty much means nothing and is based on nothing.
There is plenty of data showing that fructose is not safe -- but the  effects on the nation's health have not been immediate. That is why we  are just now realizing the effects of the last three decades of  nutritional misinformation.
As if the negative metabolic effects are not enough, there are other  issues with fructose that disprove its safety:
• More than one study has detected unsafe mercury levels in HFCS[ii].
• Crystalline fructose (a super-potent form of  fructose the food and beverage industry is now using) may contain  arsenic, lead, chloride and heavy metals.
• Nearly all corn syrup is made from genetically modified corn, which comes with its  own set of risks.
The FDA isn't going to touch sugar, so it's up to you to be proactive  about your own dietary choices. 
What's a Sugarholic to Do?
Ideally, I recommend that you avoid as much sugar as possible. This is  especially important if you are overweight or have diabetes, high  cholesterol, or high blood pressure. 
I also realize we don't live in a perfect world, and following rigid  dietary guidelines is not always practical or even possible.
If you want to use a sweetener occasionally, this is what I  recommend:
1. Use the herb stevia.
2. Use organic cane sugar in moderation.
3. Use organic raw honey in moderation.
4. Avoid ALL artificial sweeteners, which can damage your  health even more quickly than fructose.
5. Avoid agave syrup since it is a highly processed sap  that is almost all fructose. Your blood sugar will spike just as it  would if you were consuming regular sugar or HFCS. Agave's meteoric rise  in popularity is due to a great marketing campaign, but any health  benefits present in the original agave plant are processed out.
6. Avoid so-called energy drinks and sports drinks because they are  loaded with sugar, sodium and chemical additives. Rehydrating with pure,  fresh water is a better choice. 
If you or your child is involved in athletics, I recommend you read  my article Energy Rules for some great tips on how to  optimize your child's energy levels and physical performance through  good nutrition.

Uh, feel like an idiot who doesn't know what? *smiles* How are you feeling? I did indeed know about this. Unfortunately, it is in practically everything. The real answer is probably to ditch most processed foods and cook the whole foods way not to mention from scratch using healthy ingredients. Very informative post.
ReplyDeleteThanks! I'm doing ok. How are you?
ReplyDeleteSame old same old. I miss you man! It has been too long. We should talk sometime. OK?
ReplyDeleteThanks for a fantastic article. Do you mind if I post a link from our farm's Facebook page? We're old school certified organic (since 1991) but new at the Facebook thing etc. Corn syrup is disgusting and it's in everything.
ReplyDeletePlease do!
