Why your beef, bananas and coffee beans have gotten so expensive

For evidence that the cost of food in the U.S. remains hard to stomach for many households, look no further than the price of bananas, beef and coffee.

Banana prices were up 6.9% in September from a year ago, ground beef has risen 12.9% and roasted coffee has jumped an eye-watering 18.9%, according to the most recent Consumer Price Index data for September. And now for the bad news.

"One of the questions that I'm asked a lot is, when are prices coming down? And my answer is simple: never," Phil Lempert, food industry analyst and editor of SupermarketGuru, told CBS News. "The best that we can hope for is stabilization."

So what's behind the surging price of such foods? There are a mix of factors, ranging from the impact of climate change on crop harvests and U.S. tariffs on imports
