General Mills owns Cascadian Farm, and the name behind Kashi is Kellogg. Barbara's Bakery is owned by Weetabix, the leading British cereal company, which is owned by a private investment firm there. Mother's makes clear that it is owned by Quaker Oats (which is owned by PepsiCo). Health Valley and Arrowhead Mills are owned by a natural food company traded on the Nasdaq, Hain Celestial Group; H. J. Heinz owns 16 percent of that company.
The cereals sold under the Peace label are owned by Golden Temple, a for-profit company owned by a nonprofit group founded by the late Yogi Bhajan, who made his fortune from Yogi Tea, Kettle Chips and a company that provides security services.
Of the companies that made the cereals tested, only Nature's Path, a Canadian company, has no parent company.

So, while that's not the best of news, I do think it's important to note that Nature's Path isn't owned by anyone (yet.)
What we need is a good worker-owned cereal company...
