When I was growing up, we used to climb a mulberry tree in our neighborhood. In Hindi, we call mulberries 'shehtoot'. Luckily, we can get dried black mulberries in USA. These are sweet in flavor. I soak them overnight and add them to breakfast bowls.
Where to buy them? See Berries: Where to Buy in USA?
Health benefits: As of Oct 2020, not much written by Dr Greger specifically about these berries. I found that mulberries are Iron Rich Berries.
