I knew a girl who lived in the US for a few years. She said that they had a program where she lived where they got given a box of food from the Government (every month, I think?), to supplement their grocery shopping.
I think it was this:http://www.fns.usda.gov/fdd/programs/csfp/csfp_faqs.htm
The Commodity Supplemental Food Program (CSFP) works to improve the health of low-income pregnant and breastfeeding women, other new mothers up to one year postpartum, infants, children up to age six, and elderly people at least 60 years of age by supplementing their diets with nutritious USDA foods.
CSFP food packages do not provide a complete diet, but rather are good sources of the nutrients typically lacking in the diets of the target population.
Food packages include a variety of foods, such as infant formula and cereal, nonfat dry and ultra high temperature fluid milk, juice, farina, oats, ready-to-eat cereal, rice, pasta, peanut butter, dry beans, canned meat or poultry or fish, and canned fruits and vegetables.
