The next time you're out in public, take a look around you and imagine that one in five people you see can't afford to eat on a regular basis. That's the reality of a new poll that says a significant amount of Americans are having trouble putting food on the dinner table, reports Gallup.

The poll, based on the responses of 177,662 Americans from January to June, found that one in five adults didn't have enough money to buy food on more than one occasion in the last year. The data, which pinpoints the percentage of Americans with food security problems at 18.2 percent, is not much of an improvement from last year's results, when the percentage was 18.6 percent. 

Worse, droughts—which have wreaked havoc on crops and affected nearly 80 percent of agricultural land in the U.S.—make the horizon look bleak for food prices. The Huffington Post reports that by 2013, Americans can expect a four percent increase at the checkout line.
