Energy Density of Food and Portion Size
What are the three factors that influence the energy density of food?
-dietary fat -fiber -water
int eh Combo study, what were the 4 factors that influenced energy intake
-energy density of the meal -taste of the foods -portion sizes -how hungry the person is
how many kcals do very low energy dense foods have?
0-0.6 kcals/g
how many kcals do low energy dense foods have?
0.6-1.5 kcal/g
how many kcals do medium energy dense foods have?
1.5-4.0 kcals/g
how many kcals do high energy dense foods have?
4.0-9.0 kcal/g
which group in the Ello-Martin study reported less hunger?
RF+increased fruits and veggies (they ate large quantities of food)
Which is more important in determining energy intake: amount of food or energy density?
amount of food
how does dietary fat influence energy density?
fats are the most dense (by way of kcals)
how does fiber influence energy density?
fiber increases food volume but does not contribute to kcals
what is the best way to preload?
large, low energy dense preload like a salad
when adults are informed they are eating low energy dense foods, do they compensate and eat more kcals?
no
How does water influence energy density?
the more water, the less dense the food is.
how have portion sizes changed over the years?
they have increased -the more people are served, the more they will eat
What is the formula for calculating energy density of food?
total kcals/ total grams
can you get enough protein by only eating low energy dense foods?
yes
