food shortage in America?

According to a Slate article, New York City food banks are even turning people away due to shortages this winter. Here's an excerpt:

Well, the results are in: Turns out that people actually do need the food that they aren't getting and no, charity is not making up for the shortfall. Bryce Covert at ThinkProgress reports on how the cuts to SNAP have created a surge in demand on food banks, causing the food banks to run short on food and even turn people away. Food Bank NYC surveyed the food charities of New York City and found that 85 percent of food pantries and soup kitchens are reporting a surge in visitors asking for food. In fact, the number of people turning to food banks is higher now than it was in the aftermath of Hurricane Sandy. Nearly half of food pantries and soup kitchens don't have enough food to assemble proper meals. More than a quarter have run so low on food that they've had to turn people away.

But on another side of the internet, Professor Barry Eichengreen of U.C. Berkeley, an economist interviewed at Davos, predicts 300,000 new American jobs per month in 2014 and 3% economic growth. He does express caution and note that the headline unemployment rate is deceptively low (the interviewer clarifies that this is due to the low worker-participation rate).
