I think that there are two issues here:
It is certainly true that (in the UK) poorer people are more efficient
in terms of caloric intake per penny than richer people. This is usually
because the food habits of poorer people usually predispose them to
eat foods that are high fat and energy dense. This is for a variety of
reasons to do including access (physical and economic), taste, being
'filling', and the need to be sure that food bought will not be wasted.
However I am not so sure that in terms of nutrients this efficiency
remains. Again, in the UK (and Europe), poorer people can often be
malnourished which would indicate that diet quality and variety is not
adequate. Similarly poorer people consume more processed foods for
reasons of cost. These data can be easily found in the National Dietary
and Nutrition Surveys undertaken by UK and other government.
