A systematic review of laboratory studies suggests that luteolin, a natural compound found in foods like celery, parsley, and green peppers, may help reduce brain inflammation. The review looked at how luteolin affects microglial cells, the immune cells of the brain. When these cells become overactive, they can cause inflammation that contributes to conditions like Alzheimer's and multiple sclerosis.
The findings show that luteolin can suppress the overactivation of microglial cells and reduce the release of inflammatory signals. It also boosts the brain's own antioxidant defenses. These effects could potentially protect against damage from chronic inflammation.
However, this research is still early. The studies were done in cells and animals, not in people. Luteolin also has two major challenges: it is not easily absorbed by the body, and it has trouble crossing the blood-brain barrier. This means that even if it works in a lab dish, it may not reach the brain in high enough amounts to have an effect.
What does this mean for you? While luteolin-rich foods are healthy, there is not enough evidence to recommend supplements for brain health. More human studies are needed to know if luteolin can truly help with brain inflammation.
