Synopsis

Documentation

data Food Source

The Food data type consists of four things:

foodname A name of the food.
macros The macro nutrients of that specific food-item.
calories A calculated caloric value saved in kilo calories.
amount The amount of the actual food.

Constructors

Food
Fields foodname :: Name macros :: Macros calories :: Int amount :: Weight

Instances

Show Food	`Food` is an instance of the Show class, so it can be printed onto the screen.
Monoid Food	`Food` is an instance of the Monoid class. That leads to the possibility of combining foods to meals together.

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

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

kcal :: Food -> Int Source

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 Source

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.

prot :: Food -> Float Source

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

fat :: Food -> Float Source

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

carb :: Food -> Float Source

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

addFood :: Food -> Food -> Food Source

The addFood function does the combination of two foods into another one.
