The Kroger Co. (NYSE:KR) and Costco Wholesale Corporation (NASDAQ:COST) can help investors sail through the volatility in the U.S. food retail market, which has been ramped up by severe drought, high inflation levels, and the global food crisis. Therefore, Kroger and Costco are good investment choices as they provide diversification benefits, steady growth, and stability to the investment portfolio amid rising food prices. There was a 13.4% jump in grocery costs over the prior year in August, per a WSJ report.
