Food Insecurity: An Introduction

"What Is Food Security?

Food security for a household means access by all members at all times to enough food for an active, healthy life. Food security includes at a minimum:

• The ready availability of nutritionally adequate and safe foods.
• Assured ability to acquire acceptable foods in socially acceptable ways (that is, without resorting to emergency food supplies, scavenging, stealing, or other coping strategies).

...and Food Insecurity?

Food insecurity is the limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire acceptable foods in socially acceptable ways."
