You should feel
perfectly safe to eat and drink everything and the tap water is safe. The health
services are good and you will be able to find an English-speaking doctor
easily. Residents of EU countries are eligible to receive free emergency medical
care. Medical insurance is always a good idea for additional cover for travelers.

I cut my foot very badly on the island of Kea and had to get stitches
at the local clinic. I was nervous of course but in the end it was
a very enjoyable experience after the initial trauma passed. And
it was Free! (and I was not a resident of an EU country, or at least they didn't know I was because they did not even ask) So if you
get hurt don't be afraid. But if you get seriously injured keep in mind that even though health-care is free for everyone, the members of the government and other wealthy people go abroad for serious operations. But there are clinics and hospitals on all the islands.
My brother had an emergency appendectomy on the island of Lesvos and survived, in fact he thought the doctor was pretty good even though the hospital itself was so run down he thought he was going to die there.
