Caloric density, different from nutrient density, is an important
means that is used to keep us coming back for more.
Food For Freedom Review The caloric density
or energy density of a particular food is a measurement of the average
calories per unit (gram or ounce or bite) of that food. All foods
contain nutrients. Unlike calorie dense foods, nutrient dense foods are
high in nutrients for the number of calories per unit (gram or ounce or
bite) they contain. Foods that are energy or calorie dense have a high
concentration of calories per bite. Some common everyday processed foods
that are energy dense are the packaged snack foods, frosted cakes with
filling, cookies, and candies. Traditional fast foods such as
cheeseburgers, fried chicken, and French fries and bakery items like
doughnuts are legendary for their energy density. Junk foods are
considered empty calorie foods because they are low in nutritional
density and high on calories per ounce or bite. These high energy dense
or high calorie dense foods offer a high concentration of calories per
bite, and are associated with high pleasure by the brain These foods are
designed to be tasty (i.e. potato chips) and not filling. Because junk
foods are low in satisfaction value, people tend not to feel full when
they eat them. This low satisfaction experience almost always leads to
over eating. Junk food is characteristically high in palatability, high
in fat, and high in calories, but low in fiber and volume.
Low
energy dense foods, in contrast to high energy dense foods, tend to be
highly nutrient dense. In general they are moist and juicy. Low energy
dense foods have a high percentage of fiber that retains their natural
water. Most vegetables, fruits, and legumes are examples of low energy
dense foods.
