(.@) :: Weight -> (Weight -> Food) -> Food

A simple operator so one can write the Weight value prefix to the food.

kcal :: Food -> Int

kcal takes a food item and gives back the kilo-caloric value. This value is calculated from the macro-nutrition values.

foodGenerator :: String -> (Protein, Carb, Fat) -> Weight -> Food

This function is a smart constructor to construct a food item. If no Weight is supplied, a food generating function for a specific food item is returned.

The prot, carb and fat functions return the value of the macro-nutrients in gram's.

fat :: Food -> Float

The prot, carb and fat functions return the value of the macro-nutrients in gram's.

carb :: Food -> Float

The prot, carb and fat functions return the value of the macro-nutrients in gram's.

addFood :: Food -> Food -> Food
