Eat your vegetables bait and switch

At the grocery this week and a new kind of pasta caught my eye -- instead of just tinting your tricolor pasta in different colors, they promise a full serving of vegetables.

But wait -- you have to eat 4 ounces of pasta to get that serving of vegetables.  That's a lot of pasta, as I know well because I weigh my pasta before cooking (I use between 4.5 and 5 ounces for two adults, when that's the only entree).  In fact, the "official" serving is just 2 ounces, as you can tell on the side of the box.

And here's another brand, same concept, same misleading display on the front of the box.

So why the bait and switch?  Why not just say "a half serving of vegetables in each serving of pasta"? That's good right there.

If your intention is to make it easy and appealing for people to eat more vegetables, then making them think they're getting more than they really are seems counterproductive.
