“You deserve a snacking experience this good,” says the label of Planters new line of nuts (cashews, almonds, or peanuts) dipped in milk chocolate. “So treat yourself to the pleasure of Planters Nuts in Chocolate.”

The nuts come in recloseable bags that you can zip shut. Our advice: Keep them zipped.

According to the package, each serving (13 cashews or almonds or a quarter-cup of peanuts) has five grams of saturated fat–a quarter of a day’s worth. So much for Planters’ Web site’s advice to “substitute unsaturated fats for saturated fats in your diet,”

The chocolate industry has worked hard to convince consumers that its candy makes you healthier because it’s loaded with antioxidants that may help prevent cancer and heart disease. Never mind that the evidence is slim and that Americans aren’t. They’ve got a product to sell.

Of course, the first ingredient in the chocolate coating is sugar, which adds to each serving’s 220 calories. That’s assuming you stop at 13 nuts. The more you zip and unzip, the more those numbers start to climb.

Just because the bag is recloseable doesn’t mean your pants will be.
