Got omega? Dannon and Yoplait aren't the only folks to offer yogurt with a nutritionally interesting addition or two.

Now, from Iowa's Wells Dairy, we have Blue Bunny Light Omega 3 low-fat yogurt. It's sweetened with Sucralose, Neotame and acesulfame K so it has fewer calories than regular low-fat yogurt. And, as does all Blue Bunny yogurt, it contains a probiotic culture said to benefit regularity and the immune system. But the notable additive is flaxseed oil, a source of omega-3 fatty acids, said to reduce the risk of coronary artery disease.

Like many nutritionally enhanced yogurts, these tubs contain 4 ounces of yogurt, not 6 ounces.

News from the dark side Has it been only a week since Mr. Tidbit noted the debut (again) of Hershey's Special Dark "mildly sweet" chocolate chips? It has.

And that, combined with Mr. Tidbit's attempt to swear off mentioning every new-product hiccup from Hershey, should have been enough to keep him from mentioning yet another kind of Hershey semisweet chocolate chips. It wasn't.

New Premier Extra Dark chips have 6 grams of sugar per tablespoon instead of 8, an extra half gram of fat, and 60 percent cacao content. (Mr. Tidbit doesn't know how much cacao is in Hershey's regular semisweet chips, but it's clearly lots less than that.)

Although he saw it selling for the same price per bag as other Hershey chips, and the bag looks on first glance to be the same size, it's really an 8-ounce bag, not a 12-ouncer, so the new chips are 50 percent more expensive per ounce.

And how are they? Mr. Tidbit's verdict: A little smoother and lots darker in flavor than regular Hershey's chips. But (like Nestlé's pricey Chocolatier chips) worth the difference only if regular semisweet chips cause you to ask, in the pattern established by Clara Peller and Walter Mondale, "Where's the cacao?"
