A Common Kitchen Ingredient Could Be an Unexpected Secret to Fighting the Flu

A recent study has revealed that mushrooms, a common ingredient in many dishes, may hold health benefits that go beyond expectations. While previous research has linked mushroom consumption to reduced risk of depression, improved brain cell growth, and prevention of certain types of cancer, this new study sheds light on a potential role mushrooms may play in combating the flu.

The study, conducted by researchers at McGill University in Canada, was carried out on lab mice and showed that fibers found in mushrooms—known as beta-glucans—helped reduce lung inflammation caused by the virus.

The research team observed that mice given doses of these fibers showed improved lung function and a decreased risk of severe complications or death.

Immunologist Maziar Divangahi, one of the study’s contributors, explained that beta-glucans are found in the cell walls of all types of fungi, including those that exist in or on the human body. He noted that the composition and levels of these fungi may influence how the immune system responds to infection.

Unlike traditional medications that directly target the virus, this study focused on how immune-boosting fibers can strengthen the body’s natural defenses—opening the door to new therapeutic possibilities that rely on stimulating immunity rather than solely depending on antiviral drugs.
