Pineapple juice is a popular tropical beverage.

Many cultures use the fruit and its juices as a traditional folk remedy to treat or prevent various ailments.

Modern research has linked pineapple juice and its compounds to health benefits, such as improved digestion and heart health, reduced inflammation, and perhaps even some protection against cancer. Meanwhile, not all evidence has been conclusive.

Pineapple juice may contribute to a stronger immune system.

Test-tube studies suggest that bromelain, a mixture of enzymes naturally found in pineapple juice, may activate the immune system.

Bromelain may also improve recovery from infections, such as pneumonia, sinusitis, and bronchitis, especially when used in combination with antibiotics.

However, most of these studies are dated, and none have examined the immunity-boosting effects of pineapple juice in humans. Therefore, more research is needed to confirm these results.

Some research suggests that pineapple juice may contribute to a stronger immune system. It may also help increase the effectiveness of antibiotics.

However, more studies are needed before strong conclusions can be made.
