you might think that why not you self pack your food for holidays, but such solution will not work in your favour as in what way you pack, its definite that eatables will get contact with air and might be to dust particles too which can destroy the nutrition and freshness level of food and here too you will have chance to get ill, so again is the only solution that is . packed food
In market too, you have seen several packed eatables and I am sure at least one of such you have used which might be in form of packed wheat, packed flours, packed grams, packed pulses etc. Even junk food also comes in packed form and is flooded in market. Such packed eatables are now widely recommended by nutritionists too and the prime reason behind such recommendation is the nutrition level which is kept preserved in such food by packing in proper way.
