In these regions there are like National Beliefs, belief that when anyone hears them they sound outlandish...I dont know what they are but you all do...There are plenty of them...Instead, take 1 just 1 of them and replace it by this:

put in every corner of the city/country you know those soda machines that you got to put the dollar...Instead create soda machines but of Bananas....And put them in every corner/block of the whole city/country...Tell them that instead of believing in 1 belief to take: 5 cents or 10 cents place it in the banana soda machine and eat 1 banana....And if they ate 1 already and they have an extra nickle think of their child or parents...

It doesnt have to be every day it could be 3 times a week...Did you know in central America there is more coffe machines than banana soda-machines...

yet if you dont drink coffe every nothing will happen to you, yet if you dont eat fruits YOU WILL GET SICK...

Tell them that eating a banana every 2 days will determine if they die 5 years later when they are an elderly or 5 years before the day they were suppose to die when they are elderly....

Eating fruits everyday is like doing exercises, it has almost the same equivalent...

ON ANOTHER NOTE:

did people know that, Parasite Worms can give them diabetes???I remember reading it in my microbiology book...They can get into the bloodstream and burrow onto the pancreas, totally destroying it...
