Using a gas chromatograph, chemists burn a small sample of a food (or a thoroughly homogenized, uniform sample). The flame emitted by the burning sample emits light of various frequencies, corresponding to the individual elements and compounds present in the sample. The spectrum of light is analyzed to determine the chemical content of the sample.
Additionally, foods will be analyzed chemically, as what we call 'vitamins and minerals' in nutritional terms, we call organic proteins and acids, and inorganic metallic compounds. Each of these will have its own chemical properties which can be detected in a laboratory environment.
Usually, however, the values for complicated, prepared food items are estimated by calculating them mathematically from known values for basic food items.
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.

Nutrient Density
Nutrients for the calories it provides
There are several foods that contain a large amount of nutrients. The whole egg is one of the most common foods that contain the largest amounts of nutrients
Junk food would. It's just empty calories with no actual nutrition.
Storing food is not a function of nutrients because nutrients are derived from food.
Kilo joules are used to measure the amount of energy stored in food.
Well for that you will have to calculate the amount of food you eat and then put them in the right groups of the food pyramid to find out. you can go towww.mypyramid.gov and find out!!
Calorie (upper case C) refers to food calories, or kilocalories. It's used to measure the amount of energy foods or individual nutrients provide when consumed. calorie (lower case c) refers to energy in general, not food energy. It's used to measure the amount of energy needed to increase the temperature of 1 gram of water by 1 °C at standard atmospheric pressure (101.325 kPa)
Cal means calories. It is a measure of the amount of energy that a particular food has. So, if we eat that particular food, then we will obtain that amount of energy.
