High-fructose corn syrup in soda has much more fructose than advertised, study finds

High-fructose corn syrup is often singled out as Food Enemy No. 1 because it has become ubiquitous in processed foods over about the last 30 years – a period that coincides with a steep rise in obesity. One of the primary sources of HFCS in the American diet is soda – in fact, many public health advocates refer to soda as “liquid candy.”
That nickname is more apt than advocates realized, according to a study published online this month by the journal Obesity.
Researchers from the University of Southern California’s Keck School of Medicine went shopping in East Los Angeles and bought 23 cans and bottles of popular beverages. Then they sent them off to a laboratory in Massachusetts that used a technique called high-performance liquid chromatography to determine how much fructose, glucose and sucrose were in each sample. Each beverage was tested three times, and all samples were unlabeled.
Before we get to the results, let’s pause for a quick review on sugars. Fructose and glucose are simple sugars. Fructose is sweeter than glucose and has been shown to do more damage to your metabolism. Sucrose – better known as table sugar – is a 50-50 combination of fructose and glucose. The HFCS used in soda is supposed to contain no more than 55% fructose and 45% glucose, according to the Corn Refiners Assn. (Another popular formulation is 42% fructose and 58% glucose.) This slight difference is the reason why we here at Booster Shots frequently say that HFCS is just as unhealthy as “natural” sugar.
But it turns out that some of the stuff they put in soda isn’t HFCS, it’s RHFCS – Really High Fructose Corn Syrup.
The Keck researchers found that the sweeteners in Coca-Cola and Pepsi contained as much as 65% fructose (and only 35% glucose), and Sprite registered as much as 64% fructose (and 36% glucose).
“The type of sugar listed on the label is not always consistent with the type of sugar detected,” they wrote. “Considering that the average American drinks 50 gallons of soda and other sweetened beverages each year, it is important that we have more precise information regarding what they contain, including a listing of the fructose content.”
To make sure the high-performance liquid chromatography tests were accurate, the researchers also sent samples of pure fructose, pure glucose and pure sucrose. The test detected 9.9 grams of fructose in a 10-gram sample of fructose, 9.8 grams of glucose in a 10-gram sample of glucose, and 9 grams of sucrose in a 10-gram sample of sucrose.
The study included a few other surprises:
- Mountain Dew had 13% less sugar than advertised on the label, and Dr. Pepper had 8% less.
- Tested samples of Mexican Coca-Cola – which is supposedly made with cane sugar instead of HFCS – contained no sucrose, only fructose and glucose in a 52%-to-48% ratio.
- 17% of the sweetener in Red Bull was fructose, even though sucrose and glucose are the only sweeteners listed on the label.
Nestle continued: "At most, HFCS is supposed to be 55% fructose, as compared to the 50% in table sugar. Most foods and drinks are supposed to be using HFCS that is 42% fructose. A percentage of 55 is not much different biologically than 50, which is why the assumption has been that there is no biologically meaningful difference between HFCS and table sugar. This study, if confirmed, means that this supposition may need some rethinking."
The USC researchers pointed out that the U.S. Food and Drug Administration allows for some wiggle room on nutrition labels. Sodas are allowed to have as much as 20% more of a nutrient – including sugar and HFCS – than is indicated on the side of the can. Even Cokes and Pepsis with 65% fructose instead of 55% are only 18% higher than advertised.

So, Mexican Coke that the US market gets is not what we thought it was, beet or cane sugar?Don't worry, be happy. Meher Baba

Sorry if i dug this up. But it should be known that different bottlers in Mexico use different formulations for Coca-Cola. For example:
Coke from Tijuana has the best taste to me very even, not too sweet but yet not too bitter, Jalisco, Acapulco, Aguascalientes are also decent.
However Coke from Nogales, Mexicali, Zacatecas...is not so good.
It's also worth noting that 90% of the 12oz bottles I have found at Smart N Final, Costco, and other stores have been the more bitter Mexicali formula.
However I once saw some 12oz at Food 4 Less that was from Tijuana...only once in 5 years have I found that variant.
Always look at the cap to see which bottler it is, then note the taste associated with it, and you'll never fail picking the right one up next time.

There seems to be a time-relationship, too. I once kept an unopened 2-liter bottle of 7-Up refrigerated for several years, and then tested it to find that the sugar content had basically become 100% glucose. So, I guess there's a reaction that eventually breaks down the fructose into glucose. Possibly the latter is slightly more stable?
It would be interesting to test a bottle right off the production line. To account for how much better the sodas that start with sucrose taste, it might be that near 50/50 fructose/glucose mixtures are "special". Or maybe the enzyme process to produce fructose from corn syrup has a side effect that shifts the taste slightly? I'm guessing that *someone* has done research on this. Perhaps the soda companies before they first started using HFCS....
