experience Food Insecurity - the people living in these households are
not able to meet their nutrient needs every day. These people may be
forced to base their food choices mainly on cost
-When it comes to preparing food, time is often limited; because of this,
the foods that people choose to have changed over the years (research
shows that Americans now want to spend less than 15min preparing a
meal). As a result, supermarkets have changed the kinds of foods they
sell, as well as how the food is presented
-Convenience also influences food choices because foods that are right
in front of us are more likely to be eaten (In 1970s, Americans spent
about 25% of their total household food budget on eating out. Compare
that with almost 45% today.)
