Acai (pronounced ah-sigh-ee) berries are one of the healthiest berry varieties in the world along with blueberries, strawberries, raspberries and others. They are about 1-inch (2.5-cm) round that grow on acai palms in the Amazon rainforests. Their dark purple skin and yellow flesh cover a large seed, while the pits are similar to those of apricots and olives.
Technically acai berries are drupes but are still considered a part of the berry family. They are high in antioxidants, vitamins and minerals that are necessary for the body and are also known to aid weight loss, reduce bad cholesterol, and promote a healthy heart.
Acai berries are usually soaked to soften their outer skin and mashed to form a dark purple paste. The shelf-life of fresh Acai berries is a small window, hence these are largely exported in puréed or powder form to add to meals, smoothies and more.
