Nutritional information corresponds to the last level of semantic recognition - level 5 out of 5 - of the LogMeal Images API. The information provided at this level is based on the dish recognition applied on the third level, either provided through the single dish recognition or the several dishes recognition. This means that only after a recognition procedure has been applied on a certain image the nutritional information can be accessed. The same behaviour is required for accessing to the ingredients information service.
The information provided consists of 42 nutritional indicators calculated with respect to the ingredients information provided on the previous level. Even though, one can always change the total quantity consumed for a specific dish through the /confirm/quantity endpoint. Some examples of nutritional indicators provided are: carbs, energy, cholesterol, calcium, iron, fiber, potassium, sodium, etc.
