Diamond of California Walnuts

In 2010, a class action was brought against Diamond Foods alleging that the company made false and misleading statements in its marketing material about the health benefits of eating walnuts. (Zeisel v. Diamond Foods, Inc., Case No. 3:10-cv-1192-JSW, N.D.Ca.)

Update:  In 2012, the parties settled this lawsuit.  Diamond agreed to provide $2.6 million to reimburse consumers who bought its walnuts.  If you purchased Diamond of California walnuts between 2006 and 2012, you may be eligible for a refund of $3.25 or $8.25.
