While I don't go around telling people soda is "bad," I don't think it's good: it's full of sugars or sugar substitutes; some kinds of soda, namely colas, contain phosphoric acid, which, according to some studies, may harm bones. That said, I don't always avoid soda: now and then, I'll order one to have with a burger or with popcorn at the movies. I usually order a Diet Coke. Why? For years, I drank tons of diet soda-and that's what my taste buds grew to like. Seltzer is a great healthy alternative to soda. But when it comes to diet soda versus regular soda, what's really the better choice? I decided to weigh the pros and cons of each.

The Cons of Regular Soda

Con: It's full of added sugars, usually in the form of high-fructose corn syrup. High intakes of added sugars are linked with high blood pressure and high triglyceride levels, risk factors for heart disease-which is why the American Heart Association (AHA) recommends limiting all sugars to no more than about 6 teaspoons a day if you're a woman, no more than 9 teaspoons if you're a man. A 12-ounce can of cola has about 8 teaspoons-which translates to about 130 calories. So one soda won't make or break your diet, particularly if you make room for it by cutting out something else, but if you drink too many, these calories can add up to major weight gain. Side note: One of my college friends lost 20 pounds in about six months just by eliminating sodas. (He'd been a big soda drinker.)


The Pros of Regular Soda

If you're trying to avoid artificial sugar substitutes, you won't find them in there. Yes, I know that some people consider HFCS a chemical akin to the artificial sweeteners found in diet sodas; if you're among them and crave a soda, you could consider a variety sweetened with cane sugar.

The Cons of Diet Soda

It contains sugar substitutes, which some people prefer to avoid. Some studies show that consuming no-calorie sweeteners may actually make you hungrier. But, in other research, scientists didn't find artificial sweeteners to stoke appetite, so the jury's still out on that.

The Pros of Diet Soda

Sodas with no-calorie sweeteners don't directly add calories to your diet; they also may be better for your teeth, since bacteria can't live on artificial sweeteners-they need sugars.

So which is better? Only you can decide. Personally, looking at this pro/con list makes me thirsty for… some seltzer.
