Do we not rely enough on natural foods?

[Ayesha]

Though knowing processed foods are unhealthy,we rely on processed foods more than natural food. We know artificial ingredients of canned food or preservatives have negative effects on our body. Why? The possible answer might be that we are to much busy with life. We always don't have enough time to cook natural foods. But more appropriate answer might be that we got habituate with these easy foods.There's no hassle to cook and its time saving. We distribute all our times in so big assignments that we never get enough time for dispense on our little health!

Poor peoples who depends on food bank have no choice or option. They only think of fulling their belly with anything eatable. They are not concern of health . Food is more important to them than health. How can donors give natural foods to these people? is there any option to preserve natural foods for week or month long without preservatives?
Be practical my friend, goods of food bank comes from distant places. Without being canned or processed there's no other way to store food there.
