One way in which the public can be educated about diet and nutrition is to know, what exactly is the composition of the various foods that they eat. In the West, where one can easily assess the food intake, eg., two slices of white bread, one apples, a slice of pizza and so on as most of the food is standardised. In India, on the other hand the way the food is prepared is very complex and hence it is extremely difficult to quantity what we have eaten.
