Would they eat rice? Goat meat? Fish? Bread? Pumpkin? Apples? And what would they drink? Water? Juice? Milk? Soft drinks?
I found this wonderful clip which shows families in their own homes with food for one week.
There is a cost estimate. But most of the information is in the pictures. Some families are large. Some eat fresh foods. Some eat very little. Some people seem to eat food from boxes. And the prices indicate not just the income of the family but cost of living in that region. Perhaps they indicate political and social factors. Who is healthy? Who will live longer?
