Acai berries stem from a palm tree in the rainforest of Brazil.

Acai

This tiny, dark, round fruit is about the size of a blueberry (with a large, inedible seed) and tastes like chocolate and wildberries. Acai (pronounced ah-sigh-ee) is enjoyed mostly as juice in health drinks and smoothies or dried and mixed with granola. Called a "superfood", acai is rich in anthocyanins (responsible for its royal purple color) and essential fatty acids, both believed to provide many health benefits.
