Ricotta is a traditional Italian cheese made from whey, a byproduct of other dairy processes, and is often associated with whole, unprocessed foods like pasta and pizza. You're not getting much actual food value from ricotta since it's essentially a concentrated liquid, but in moderation, it can be a decent source of protein and calcium.
Did you know
Ricotta means 'recooked' — it's made from whey left over from other cheese production.
