An article from the New York Times on how income effects diet. Not only on how generally healthier foods are more expensive but also the fact that some families can not afford to buy new foods for their children to try in case they do not like it. Leading to the families having to spend even more money on food to replace the food that the children refuses to eat.
If you combine this article with several of the other reposted articles included on this site on how much nutrition has an impact on mental health and performance in all aspects of life you can see how this is a real issue for lower income families.
A further article below from the Guardian highlights the staggering statistics that 25% of of children in poorer areas are obese compared to 11% in affluent areas. Further proving the link between income and eating habits.
