Considering the rise of food prices in recent years, Tyson Foods (NYSE: TSN) might seem like an obvious pick. Moreover, Tyson's history of dividends goes back decades, but the payout level did not frequently change until 2012 when the company began to approve annual increases. So it calls into question whether the increases will continue, or will it stand pat (or even slash the dividend) and wait for business conditions and free cash flow to improve?
