Oh, Mother's, what have you done?

San Diegan Shavonda Hawkins on January 21 filed a putative class action suit in federal court against Michigan-based Kellogg Co., the big cereal-maker.

Hawkins, represented by the Weston Firm, says she bought Mother's Cookies, a Kellogg product that contains partially hydrogenated oil, a trans fat.

Hawkins notes in her suit that last year, the Food and Drug Administration determined that partially hydrogenated oil is unsafe for use in food. A number of countries have banned it, according to the suit. She says she has been potentially damaged by ingesting artificial trans fat.

"There is a scientific consensus that trans fat is extremely harmful," says the suit. It claims that artificial trans fat can cause breast, prostate, and colorectal cancers; Alzheimer's disease and cognitive decline, organ damage, and type 2 diabetes.
