PepsiCo Inc. (NYSE: PEP) today reported better-than-expected third quarter results, helped by strong sales of healthy snacks and robust growth overseas.

Net income rose 17% to $1.74 billion, or $1.06 a share, from $1.49 billion, or 89 cents, a year earlier. Sales rose 11 percent to $10.2 billion. Excluding a one-time gain, the Purchase, New York company's results beat Wall Street expectations by 3 cents.

"Our third quarter performance was very strong, with double-digit revenue and operating profit growth," said Indra Nooyi, the company's chairman and chief executive in the earnings release. "All of the Company's operating divisions successfully navigated through an environment of higher input costs in order to deliver balanced top- and bottom-line performance."

PepsiCo reiterated its previous guidance for full year earnings of at least $3.35 per share and slightly rose its cash flow from operations forecast to be at least $7 billion. Capital spending is seen at about $2.6 billion.

When I was writing about Jones Soda Co. (NASDAQ:JSDA) and their announced switch to sugar instead of high fructose corn syrup as sweetener, I didn't read all the way to the end of the Wall Street Journal [subscription required] story. I should have, though, as it's really the big news.

PepsiCo, Inc. (NYSE:PEP) funded a study on high fructose corn syrup, which indicates that sugar and high fructose corn syrup have nearly the same effect on the body, and found no difference in the way the two substances contribute to weight gain. (The study is being written up for submission to a journal by researchers at UC Davis.) Pepsi is promoting this study heavily and said in response to Jones' move, "To say cane sugar is healthier than HFCS just isn't true. Marketing a myth for a competitive advantage is irresponsible and short-sighted."

But. But! Pepsi is working on some versions of its most popular sodas, including Sierra Mist and Pepsi itself, that contain sugar instead of high fructose corn syrup -- along with the removal of some preservatives and artificial colors. This news, reported by Beverage Digest magazine, seems at cross purposes with Pepsi's spokesman's claim.

If Pepsi is so sure high fructose corn syrup is safe -- and so interested in making sure consumers believe it -- why would it even dream of converting? Something tells me we haven't heard the end of Pepsi's evaluation of HFCS.

Remember the 90s? Ahh, the 90s, when I was in high school and college and we all believed that (a) bagels and cereal were diet foods and (b) drinking a Diet Coke with your pizza was a good way of cancelling out the calories.

The Coca-Cola Company (NYSE:KO) has announced that it will be releasing a new calorie-burning soft drink called "Enviga" in November, just in time to balance out your Thanksgiving dinner I suppose. That's right, I said "calorie-burning." It could be that my pizza/diet soda strategy from 1992 could finally actually work!

Enviga uses green tea extract (EGCG, which has nothing to do with an EKG, much though my mind immediately leaps there), caffeine and calcium, and the company says it is actually proven to burn calories. Investors seem cautiously optimistic and have sent the stock up a bit, about 20 cents, since the announcement.

I don't know. First of all: the packaging looks to me like those alcoholic drinks -- totally the wrong association for Coke's target market. Second, I connect calorie-burning with the fen-phen troubles of the late 90s (yep, those darned 90s again). Third, as Sarah Gim from Slashfood points out, Enviga is only "proven" to burn calories in "healthy people with a lean to normal body type" -- those that don't really need to burn any more calories. Sarah, Sarah! Don't you know that customers don't read the small print??

It remains to be seen whether Enviga will crash and burn due to confusing packaging, or it will soon be on the desks of millions of lean-to-normal female high school and college students, who are certain that they're in need of losing just five more pounds. If I know anything about their collective psychology, I'd be betting on option #2.
