Energy and its measurement

To measure weight, we use the units of gram or kilogram. For distance we use kilometer. Similarly, for energy the units of kilocalories are most commonly used. Note that 1 Calorie (with a capital ‘C’) equals 1000 calories (or 1 kilocalorie). Technically 1 Calorie is the amount of energy required to heat up 1 kilogram of water by 1 degree centigrade. Lets not bother about the technical details. For the purposes of this blog it is sufficient to know that energy of foods is most commonly represented in Calories.

What makes up our food?

carbohydrate-richFood can be classified into 3 major components – Carbohydrates (e.g. wheat and rice), Proteins (e.g. pulses and meats), and Fats (e.g. oils and ghee). One gram of fat contains about 9 Calories of energy, whereas one gram of either carbohydrates or proteins contains about 4 Calories of energy. protein-richThus, fats are much more energy dense than carbohydrates or proteins. Other than these 3 major components, there are vitamins and minerals, that are important for normal functioning of the body, but do not have any energy values associated with them.
Thus, Calories, Carbohydrates, Proteins, Fats, Vitamins, and Minerals – these are the basic terms we will keep using in our discussions on nutrition. These are also the terms that are found on the ‘nutrition facts’ label on most of the food products. As an example, here is a label from Parle-G biscuit, which provides very basic nutritional information.

parleGThis label is very basic and does not provide a breakup of sugars as part of carbohydrates. Sometimes such selective reporting may be deliberately used to trick consumers. For those who might be interested, here is a recent case study of one of the misleading nutritional claims to make a product seem healthy.
