How do you create a food item with a bonus effect for sims for ps2?

Pink hearts:
#One Suggestion is Lobster, Tuna & Passionfruit
#To get energy boost effect: Select ingredients with high energy content
#For repulsive/nauseous meal: Use fish especially eel and squid


Pink hearts mean that when you interact with someone, you will be in love
Mode. Therefore, romantic socials will be enabled for you to use.

Black hearts mean that when you interact with someone, you will be in
Enemy mode. You are most likely to offend that person and reduce the
Relationship points.

Rain drops mean that the food will heavily deplete your bladder. Rush to the
Toilet!

Green stuff coming from the food means you have just created a repulsive
Meal which can have a nauseous effect like instant vomitting.

Stars mean your Sims get +3 skill points in all skills until it wears off.
It's an easy way to get a fast promotion as in get the stars before leaving
In the carpool.
