Study Finds Orange Juice May Help Support Immune System

Orange juice is a good source of vitamin C, folate, and antioxidants. A new study has found that orange juice may help support the immune system and reduce oxidative stress and inflammation.

For their study, researchers from Southampton University reviewed almost 200 studies that examined vitamin C and folate in orange juice and their effect on the immune system, oxidative stress, and inflammation.

The researchers found that orange juice plays a role in protecting against infections and reducing the length of the common cold. They also found that consuming orange juice during a high fat-high carbohydrate meal helped reduce the post-meal inflammatory response. Daily consumption of orange juice was found to reduce markers of inflammation such as C-reactive protein and markers of oxidative stress.

The study was conducted by researchers from the University of Southampton. It was published online ahead of print on June 24, 2021, in the journal Frontiers in Immunology.
