Some energy super fruits include Acai, Wolfberry and Camu-camu.
I have always found dark fruits and fruit juices very satisfying. particularly pomegranate, cranberry, raspberry, blackberry, blue berry and blood orange.
I'm really not familiar first hand with Acai, which is also a dark berry, but many swear by it for instant energy. Acai also helps support both the immune and the circulatory and system. Acai is also a potent antioxidant loaded with vitamins and trace minerals. But is it tasty? lol I really don't know.
The interesting thing i found is that all of my favorite fruits, including Acai (as well as purple grapes and bilberry), help promote a healthy heart, cardiovascular and circulatory system.
If you like fruit juices, there are some blends that come in fancy wine bottles like Mona-Vie
www.thegreatproduct.com/anne which includes 19 super fruits and will cost over $40 a bottle. The price to pay to return to the ancient traditions in a sophisticated modern world...
They say that when we crave a certain food or feel particularly quenched by it its because our body actually needs its nutritional properties. I always innately associated these fruits with human blood, primarily because of the juice's color. So i can't help to find it interesting that they do in fact have something to do albeit indirectly with the blood.
