Drinking of pineapple juice doesn’t only ease the irritation caused by coughs but it also helps dissolve excess mucus. One study explored the treatments that can help patients with tuberculosis. Results showed that daily intake of a mixture of pineapple juice with honey, pepper and salt helps loosen up the mucus collected in the lungs.
Pineapple juice sold in stores often includes sugar and other unnecessary ingredients that can be harmful to your health. Processing involves heating, which can potentially destroy the bromelain contained in pineapples. If you want to get the most nutrients out of a pineapple, then it is best to prepare it raw.
