Most high income nations have been overproduce food via subsidies for decades. For most countries, food security is part of national security. The obesity crisis is a side effect of that:
I think there's enough slack in the system we won't see food shortage. The lines at food banks are a different problem entirely. That's because people don't have jobs, and are afraid to spend what they do have in savings and unemployment.
There doesn't have to be a shortage for people to be hungry - just a breakdown in distribution, and we are already seeing that.
And....no, people aren't lining up at food banks because they are "afraid to spend what they have". They mostly don't have anything to spend. Free food means they can afford the electricity bill, not that they can leave savings untouched.
Not every necessity is deferred. Also, getting food from the food bank may mean saving money that you'll need to buy food on a day when you can't get to the food bank.
