The acai berry is said by many researchers to drastically increase your energy and endurance. Also, through many studies, it is shown that people from Brazil are among the most active and healthy among the whole world.
Do not be surprised to walk down a beach in Brazil and see that almost 90% of the people surrounding you will be slim (and usually showing it off too!). You will also see these people swimming, playing soccer, biking, running, surfing, all sports which make a person very healthy.
Now, as the acai berry has originated in Brazil, you will also see many people with big containers of the famous acai berry. So, it kind of seems obvious that the acai berry has a direct correlation with a person’s energy and endurance.
It is said that the acai berry boosts energy so much that warriors (Amazon warriors to be specific) used to consume it prior to going to fight/battle. Currently, it is a very popular fruit between people taking part in Jiu Jitsu. Many Jiu Jitsu pros recommend that their students regularly have acai berries, and they continue to do so. Most do, and it is evident from looking at that performance. Brazil has several successful Jiu Jitsu masters. Most of the people who eat the acai berry continuously stay in great shape, and maintain a phenomenal level of endurance.
