Just how bad for you is a can of soda?

Thanks to mercola.com for this article!

Soda is on my list of the five absolute worst foods and drinks you can consume.  The video above offers a compelling illustration of why I make this claim.

In it, reporter Yunji DeNies drinks a 20-ounce glass of cola, which contains the equivalent of 16 teaspoons of sugar in the form of high fructose corn syrup (HFCS). This is nearly three times the maximum daily sugar intake recommended by the American Heart Association.

HFCS typically contains a mixture of 45 percent glucose and 55 percent fructose (although recent investigations have found that many brand-name sodas actually contain 65 percent fructose!).

Once ingested, your pancreas rapidly begins to create insulin in response to the sugar. The rise in blood sugar is quite rapid. Here’s a play-by-play of what happens in your body upon drinking a can of soda:

  • Within 20 minutes, your blood sugar spikes, and your liver responds to the resulting insulin burst by turning massive amounts of sugar into fat.
  • Within 40 minutes, caffeine absorption is complete; your pupils dilate, your blood pressure rises, and your liver dumps more sugar into your bloodstream. As you could see in the report above, DeNies’ blood glucose level was 79 at the outset of the experiment, and after 40 minutes it had risen to 111!
  • Around 45 minutes, your body increases dopamine production, which stimulates the pleasure centers of your brain – a physically identical response to that of heroin, by the way.
  • After 60 minutes, you’ll start to have a blood sugar crash, and you may be tempted to reach for another sweet snack or beverage.

As I’ve discussed on numerous occasions, chronically elevated insulin levels (which you would definitely have if you regularly drink soda) and the subsequent insulin resistance is a foundational factor of most chronic disease, from diabetes to cancer.

Fructose Turns into Fat Far Faster than Other Sugars, and Fats

Lately, the media has finally begun reporting on the science of fructose, which clearly shows it is far worse than other sugars.

Fructose is processed in your liver, and unlike other sugars, most of it gets shuttled into fat storage. This is why fructose is a primary culprit behind obesity—far more so than other sugars. According to the news report above, drinking two bottles of soda per day can make you gain a pound of fat per week!

Aside from the weight gain, eating too much fructose is linked to increased triglyceride levels. In one study, eating fructose raised triglyceride levels by 32 percent in men! Triglycerides, the chemical form of fat found in foods and in your body, are not something you want in excess amounts.

Intense research over the past 40 years has confirmed that elevated blood levels of triglycerides, known as hypertriglyceridemia, puts you at an increased risk of heart disease.

Meanwhile, one of the most thorough scientific analyses published to date on this topic found that fructose consumption not only leads to insulin resistance but also decreases leptin signaling to your central nervous system. Leptin is responsible for controlling your appetite and fat storage, as well as telling your liver what to do with its stored glucose.

When your body can no longer “hear” leptin’s signals, weight gain, diabetes and a host of related conditions may occur. So, as you can see, fructose contributes to poor health through a number of mechanisms…

Oh, those ads that say corn syrup is natural and healthy- yeah right!

Thanks to Dr. Mercola for another terrific article:

http://articles.mercola.com/sites/articles/archive/2008/11/13/corn-syrup-s-new-disguise.aspx

According to the Corn Refiners Association, high-fructose corn syrup contains the same amount of calories as cane and beet sugar, is metabolized by the body the same way as these sweeteners are, and is an all-natural product.

Their current ad campaign insists that high-fructose corn syrup is just like honey, which is made by enzymes in a bee’s abdomen — as opposed to the enzymes and acids in centrifuges, ion exchange columns and liquid chromatographers used to make high-fructose corn syrup.

High-fructose corn syrup could be all-natural, if cornstarch happened to fall into a vat of alpha-amylase, soak there for a while, then trickle into another vat of glucoamylase, get strained to remove the Aspergillus fungus likely growing on top, and then find its way into some industrial-grade D-xylose isomerase.

High-fructose corn syrup is indeed similar to cane sugar in that it is about 50 percent fructose and 50 percent glucose. The American Medical Association issued a statement explaining that “high-fructose syrup does not appear to contribute more to obesity than other caloric sweeteners” … but they also said that “consumers [should] limit the amount of all added caloric sweeteners to no more than 32 grams of sugar daily.” Most sodas contain about 40 grams of high-fructose corn syrup.

Dr. Mercola’s Comments:

By now you’re probably familiar with the advertisements claiming that high fructose corn syrup (HFCS) is “no worse for you than sugar.” What gets me about this campaign, run by the Corn Refiners Association, is this: What decent food product has ever needed to spend up to $30 million to convince consumers it’s inherently safe to eat?

The mere fact that these ads are defending corn syrup as a natural, healthy, and safe sweetener should be a tipoff to all that something is missing from the picture.

Where are the ads defending the use of sugar? Where are the ads defending salt? Both of these have obvious health ramifications if consumed in excess, but no one has ever needed to spend millions to convince you they’re no worse than something else, and that it’s okay to keep consuming them.

The Truth about High Fructose Corn Syrup

The truth is, scientists have linked the rising HFCS consumption to the epidemics of obesity, diabetes and metabolic syndrome in the U.S., and medical researchers have pinpointed various health dangers associated with the consumption of HFCS compared to regular sugar. This is why the corn industry is now scrambling to save face and profits – NOT because it’s really okay to consume an average of 59 pounds a year of this stuff.

The American Medical Association issued a statement on June 17, 2008, stating that “high-fructose syrup does not appear to contribute more to obesity than other caloric sweeteners.” However, they also recommend you limit the amount of ALL added caloric sweeteners to no more than 32 grams of sugar daily, which, by the way, comes out to just over 25.5 pounds of sugar per year.

The AMA’s recommendation is over five-and-a-half-times less than the current yearly sugar consumption of the average American – which currently weighs in around 142 pounds a year — but is still five times higher than my own recommendation of 5 pounds of added sugar per year.

Their evaluation that HFCS is not a major contributor to obesity is puzzling, considering the fact that the number one source of calories in America is soda, which contains about 40 grams of HFCS per can – more than the AMA’s recommended daily maximum for ALL caloric sweeteners.

And that’s without adding in all the corn syrup now found in every type of processed, pre-packaged food you can think of. In fact, the use of high fructose corn syrup in the U.S. diet increased a staggering 10,673 percent between 1970 and 2005, according to the latest USDA Dietary Assessment of Major Trends in U.S. Food Consumption report (whereas sucrose consumption declined by 38 percent), far exceeding changes in intake of any other food or food group.

And what kinds of foods account for more than 90 percent of the money Americans spend on their meals? You guessed it: processed food.

All in all, according to the USDA’s report, about one-quarter of the calories consumed by the average American is in the form of added sugars – the majority of which comes from high fructose corn syrup.

Folks, this is a prescription for disaster.

Why High Fructose Corn Syrup IS Worse For You than Sugar

If you need to lose weight, or if you want to avoid diabetes and heart disease, fructose is one type of sugar you’ll want to avoid, particularly in the form of high-fructose corn syrup.

Part of what makes HFCS such an unhealthy product is that it is metabolized to fat in your body far more rapidly than any other sugar.

According to Dr. Elizabeth Parks, associate professor of clinical nutrition at UT Southwestern Medical Center, and lead author of a recent study on fructose in the Journal of Nutrition:

“Our study shows for the first time the surprising speed with which humans make body fat from fructose. Once you start the process of fat synthesis from fructose, it’s hard to slow it down. The bottom line of this study is that fructose very quickly gets made into fat in the body.”

How does this happen?

Well, most fats are formed in your liver, and when sugar enters your liver, it decides whether to store it, burn it or turn it into fat. Fructose, however, bypasses this process and turns full speed ahead into fat.

It’s basically sneaking into the rock concert through the fence,” Dr. Parks said in a previous interview with Science Daily. “It’s a less-controlled movement of fructose through these pathways that causes it to contribute to greater triglyceride [i.e. fat] synthesis.”

Ironically, the very products that most people rely on to lose weight — low-fat diet foods — are often those that contain the most fructose! Even “natural” diet foods often contain fructose as a sweetener.

How You Can Drastically Improve Your Overall Health

If you want to drastically improve your health, the answer is quite simple. To lose weight and reduce your risk of developing metabolic syndrome, diabetes, and heart disease, STOP drinking soda and processed fruit juices that are sweetened with about eight teaspoons of fructose per serving! Switch to pure water as your beverage of choice and you will be well on your way to better health.

Genetic factors clearly play an important role in the development of obesity. However, the rapidity with which the current epidemic of obesity has hit the United States and the rest of the world makes diet and lifestyle a far more likely explanation.

To preserve your health you need to focus your diet on whole foods based on your personal biochemistry, and, if you do purchase packaged foods, become an avid label reader and severely limit your consumption of goods that contain corn syrup as a main ingredient.

When in a Pinch, Choose Your Poison

However, like most areas in life, when presented with two poisons, choose carefully.

Even though HFCS is clearly something you want to avoid, it is not as bad as artificial sweeteners, which damage your health even more rapidly than HFCS. (I spent several years researching artificial sweeteners for my book Sweet Deception, which goes into these issues in great detail).

So, for example, if you have to choose between soda sweetened with HFCS (regular soda) or artificial sweeteners (diet soda), choose HFCS.

The best and safest sweetener (although illegal to use as a food additive, according to the FDA) would be the herb stevia. Personally I use a liquid stevia to flavor my Tulsi tea and it is one of the most delightful drinks I have ever had.

Dr. Mercola tells it like it is, again!

“There is a growing lineup of scientific studies 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.”
