U can change the way of cooking for nutrition value . Like soak pulses before boil . Cut vegetable on big pieces instead of small pieces . Dont put veggies in water for so much time . Dont over cook any veggies . Inastead of making veggies in pan use cooker .
Dont keep veggies in fridge a. For so long after cutting them, dont heat food again n again, dont put salt on evry fruit (if possible).
