10-in-1 food parcels were rations prepared for by the United States Army intended to provide one meal for 10 soldiers during and after the 1945 planned attack of Japan during World War II. The attack never took place, leaving an over-abundance of surplus food. Through the form of CARE Packages, the humanitarian group CARE provided a means to transfer the ration surplus to those starving in Europe.

One 10-in-1 contained:

• one pound of beef in broth
• one pound of steak and kidneys
• 8 ounces of liver loaf
• 8 ounces of corned beef
• 12 ounces of luncheon loaf (similar to SPAM)
• 8 ounces of bacon
• 2 pounds of margarine
• one pound of lard
• one pound of fruit preserves
• one pound of honey
• one pound of raisins
• one pound of chocolate
• 2 pounds of sugar
• 8 ounces of egg powder
• 2 pounds of whole-milk powder
• 2 pounds of coffee
