I over heard two guys talking at the gym about drinking a cup or two of dole pineapple juice a day to help the with muscle repair and it also has an helps with inflamation. They guy was like "dude google it, its all over google." I assume most of this is BS as I have never heard of this before and most juices are packed with sugar. IF it were true, and a big IF, I'd assume fresh pineapple would be better than canned juice
