How the Fuel Value of Foods is Measured- Science Project Idea
Foods burned outside of the body furnish the same amount of energy as if they were burned within the body.The fuel value of carbohydrate, fat, and protein is therefore obtained by burning known amounts of these nutrients in an instrument called a calorimeter, so constructed that all the heat produced is used to heat a measured amount of water.The amount of heat necessary to warm a kilogram of water one degree Centigrade, is taken as the unit.This unit is called a calorie.A pound of pure starch, sugar, or protein will yield when burned about 1850 calories, and a pound of pure fat about 4220 calories. It can be seen that if the amount of these nutrients in a food are known, it is very easy to calculate the fuel value of the food.The following list, gives the amount of each of a number of common foods which will furnish 100 calories.
Science Project Idea Calculate the amount of calories you intake over a period of a week by taking a diary of your diet daily.Based on your BMI (body mass index) should you increase or decrease the amount of calories you intake?Give ideas and suggestions how you can improve your diet.
