CBS’s “The Early Show” weighed in on baseball grub this morning for opening day, taking a look at some favorite snacks and their calorie content with the help of senior editor Matt Bean from Men’s Health magazine.

One of the biggest surprises was what to drink. Of course, water is a great option, but if you’re trying to decide between a beer or a soda, go for the brew. A 12-ounce beer is 139 calories; the cola, 155 calories (plus about 12 packets of sugar, according to Bean).

Also, 1½ cups of Cracker Jack (360 calories) is better than a large soft pretzel with cheese (593 calories). You’d have to walk up 37 flights of stairs to shed that intake, Bean said.

And you’re better off with a hot dog (280 calories) than cheese nachos (692 calories). You’d have to trek eight miles to do  penance for that indulgence.

None of these choices is exactly healthful. Bean suggested looking for alternatives, especially sushi. Given the turnover, the product should be fresh, he said.

But if I’m going to splurge on calories, I rather just head for Boog’s stand and get a great roast-beef sandwich with all the trimmings. That’s something to root for.
