Calories are the standard unit.
Nutrient Density
A human gets energy from the calories of food. how much energy the food molecules have
A calorimeter. Basically you burn food inside a box and then measure the energy you get out of it. You have to make sure that the energy does not get out of the box
how much energy the food molecules have
No, kilocalories measure the amount of energy in foods. There is between 4 and 9 kilocalories per gram in the digestible portion of any foods.
the temprature change tells t=you how much energy is being greated
The amount of energy that you can get from that food. We get our energy from calories. And when we burn energy, we burn calories. So, we measure calories to see how much energy we will get from that particular food. This tells us how much of that food we should eat, compared to how much energy we expend.
Nutrient Density
The amount of oxygen that's consumed when you burn your food is an indirect measure of the amount of energy that's released from the food. Bomb calorimeters are sometimes used to measure the energy content in food.
Food energy is usually measured in calories.
