Obviously Strict vegeterian diet is recommended in sattic ahar. Except vegetables milk is allowed. I saw few to take[atap rice] rather than ordinary ones. Then there is restriction for excessive masalas,spices,oil,etc
I think it is best to prepare food without them..all things should be properly cleaned before they are cooked
You also cannot take factory foods and things inedible[out of date].
