Food is the important aspect of life.

If you want to donate things for poor, Donating food is the best one and it has the power of healing your sins.
If you donate clothes or money to poor people, They will be happy and praise you to live long.

But if you donate food for poor/hungry people they will praise you from heart. Since you have cured their hunger.

So donate food whenever you notice deserving ones.

Thanks for the post.
