Celebrity chef and talk show host Rachael Ray has an advertising problem.

Despite claims on the label and on the product’s website that her Nutrish brand of dog food is “natural” and devoid of artificial flavors or preservatives, both wet and dry varieties contain chemicals and artificial ingredients, according to a recent class-action lawsuit against the makers of the Food Network star’s product.

At a time when consumers have been shown to project their own preference for natural food onto their furry friends with U.S. sales of pet foods marketed as “natural” exceeding $5 billion a year, the suit against Ainsworth Pet Nutrition alleges that it has “reaped enormous profits” at the expense of pet parents who paid a premium for the Nutrish dog food.

The suit points to several “chemicals and artificial and/or synthetic ingredients” — including L-Ascorbyl-2-Polyphosphate, Thiamine Mononitrate, and (to throw you a bone pronunciation-wise) caramel color — that it claims disqualifies more than a dozen Nutrish products as natural pet foods.

For its part, the Nutrish site features an “ingredient glossary” that defines L-Ascorbyl-2-Polyphosphate and Thiamine Mononitrate as both being “part of an essential blend of vitamins and minerals that helps support your pet’s overall health.” There is no entry for caramel color.
