3. The Purpose of TROC Healthy Diet Lifestyle Healthy Diet Lifestyle various diet services found on/offline which theory do I follow?? how to know the healthiness of my own diet hard for amateur to calculate the nutrition facts

4. The Purpose of TROC Then comes TROC! Then comes TROC!{ 1 create your own recipes for daily diet; 2 have nutrition facts auto-calculated; 3 adjust recipe to healthize diet; 4 recalculate, if still unsatisfied GOTO line 3; 5 cook; 6 inject food; }

5. Design Principles Syntax: - Close to recipe convention Syntax: - Close to recipe convention |- Less ambiguous |- Smooth learning curve 20-Minute Beef Stew 3 pounds boneless beef, cut into cubes 1/3 cup flour 1 ½ cups wine 3 tablespoons oliveoil 1 onion, chopped 2 carrots, cut into pieces 1 pound potatoes, cut into pieces Salt and ground pepper Coat beef with flour, salt and pepper; Warm oliveoil with pressure cooker for 3 minutes; Add wine,beef,onion,potato and carrot into the cooker; Cook on high for 20 minutes; Serve. Dish 20_Minute_BeefStew { beefToBeStewed: 3 lb BonelessBeef; flour: 1/3 cup Flour; salt: 2 g Salt; pepper: 1 g GroundPepper; oliveOil: 3 teaspoon OliveOil wine: 1.5 cup RedWine; onion: 1 unit Onion; carrot: 2 unit Carrot; potato: 0.5 lb Potato; cut beefToBeStewed into cubes; chop onion; cut [carrot,potato] into pieces; coat beefToBeStewed with [salt, pepper, flour]; cook oliveOil with PressureCooker for 3 minute; cook [beefToBeStewed, onionToBeChopped, garlic, carrot, potato, wine, oliveOil] with PressureCooker mode HIGH for 20 minute; }

6. Design Principles Semantics:- Strongly Typed Semantics:- Strongly Typed e.g. Rule: Cook Ingredient with Cookware Cook Beef with PressureCooker Cook Beef with MixingBowl - Static Typing - Static Typing - Object inheritance - Object inheritance - Integrated Metric System - Integrated Metric System e.g. olvOil: 3 teaspoon OliveOil; equivalent to 0.5 oz OliveOil Translation done at compile time

7. Runtime Runtime Routine Calls Runtime Routine Calls - Program written in TROC is translated into java code which call functions in TROC run-time API Nutrition Facts Calculation Nutrition Facts Calculation - Embedded in the TROC API functions, based on the ingredients, tools and operations involved - Formula based on the online authentic nutrient database created and maintained by Nutrition.gov
