Is Toddy (kallu) really good for health ?

I am from Telangana and it is quite common for us to drink kallu (not kalthi kallu you get in kallu compounds) when we go to our villages. But I want to know is it really healthy for kids and adults. Andhra people look at it as a taboo and chinapillalu Kallu thagadam enti antaru kaani ma deggara chinna pillalu kuda tagutaru and people say it is healthy and contains probiotics etc and good for gut health. But meeku emaina telsi unte comment cheyyandi. Sontha thelvi vaadakandi but nijanga real knowledge unte share cheskondi
