Things you might not have known about pineapples.
Pineapples contain bromelain which breaks down protein therefore the juice can be used as a marinade or meat tenderiser.
It can also be used as an anti inflammatory agent.
As I have stated, Bromelain helps to digest protein. There is some evidence that bromelain supplements may reduce swelling, bruising, inflammation and pain after surgery and injury
Digestion
Bromelain is a popular natural digestive aid due to it's ability to
digest proteins. It's used for bloating, gas and other digestive
symptoms and for conditions such as irritable bowel syndrome. Bromelain
is often used alone or in combination with other enzymes such as
lipase, which digests fats, and amylase, which digests starch. There is
little research, however, on the safety or effectiveness of bromelain
for digestion.
