Should preservatives be used in food !!

Should preservatives be used in food products. Do they help our health in any way, or are they used to make food last longer for the consumer? 🤔

for health most of them r bad in the long term but then the world has advanced .... preservatives r reqd for preserving the food.

if poss natural preservatives shud be used instead.
