Talking exactly about the how healthy South Indian foods are, I must say from my personal experience after eating these foods since so many years in Doha fromdosa-street[dot]com that, these foods items are not only tasty but also healthy for intestine microbiota.Rich in probiotics, particularly idli, dosa, uttapam, etc. Fermentation improves digestibility, enhances B vitamins and boosts the immune system. You must try these foods items. Try it, you will love it. I'm sure.Thanks!
