There has not been found a significant difference in food energy intakes among poor and non poor families in the U.S., however there is a difference in the quality and nutritional value of the food consumed. Children living in poverty consume higher amounts of saturated fat, higher cholesterol consumption and a diet based mostly on carbohydrates. Although it is a steady diet, it is made up of low-nutrient foods, largely due to the fact that this type of food is less expensive.
