Nestle is the world's largest food company, with a market capitalisation of $172 billion. They are four times bigger than Kraft ($40bn) and over ten times bigger than Heinz ($13bn). For the record, Unilever, who is very prominent in the food industry, has a market cap of $86bn.
Walmart isn't a food company, it's a retailer, so is irrelevant to the question (though out of interest, they are bigger than all of these companies, at $209bn).
Note - while some of the above companies are listed on non-US stock exchanges, the above valuations are all USD.
