Lunchables have concerning levels of lead and sodium, Consumer Reports finds

Lunchables — prepackaged boxes of deli meat, cheese and crackers — are not the healthiest option when it comes to picking snacks or lunches for kids, as they contain troublesome levels of lead and sodium, according to Consumer Reports.

The advocacy group tested Lunchables, made by Kraft Heinz, as well as similar lunch and snack kits from other manufacturers, finding cause for concern in the products popular for decades as a convenient snack or lunch for children.

"There's a lot to be concerned about in these kits," according to Amy Keating, a registered dietitian at CR. "They're highly processed, and regularly eating processed meat, a main ingredient in many of these products, has been linked to increased risk of some cancers."
