First, all canned goods are welcomed, as are many other non-perishable items, but please, please, please do not try to empty your own food stores of out of date items. As I've sorted though canned goods at the food bank I've found many items too old to give. Too much time is spent checking food usablability and safety. Give what you would serve your family.
My second suggestion is to give money. The Food Bank can buy food in lots big enough to receive large discounts. Money stretches their abilities farther than a bag of canned goods. A donation of $10 or $25 could actually buy ten times that in food. It's something to think about.
A third suggestion is to give your time. Whether you have 2 hours or two days to give, call and see how you can help. They often need office staff and have other jobs that don't require heavy lifting or dealing with the food donations.
My last suggestion is to give ALL YEAR ROUND. Spring, summer, fall or winter the need for food does not abate. Many people give during the Holiday Season, but the need is still there in July as well. Maybe a monthly check is something to consider.
Whether it's your family, your office, your neighborhood, or you alone, food banks have a big impact on the lives of many. Giving feels good!
