Imran Khan should contact Danone of France to set up Yogurt pasteurization and manufacturing plants all over Pakistan. It is a tasty way to provide calcium to even children in villages.
Dr. Yunus of Grameen Bank set up these plants all over Bangladesh, the yogurt is distributed by individuals using insulated bulk packs (to keep them cooler) who carry them to poorer neighborhoods for sale. Pricing is extremely low.
The Yogurt is also sold commercially in retail supermarket packs.
There are a variety of other conglomerates who have introduced yogurt products in the market after Grameen did some ten years ago. After All - sweet yogurt has been a Bengali staple for the last two thousand or so years, maybe more.
