While we can’t control everything that affects our brain health, some interesting studies have pointed to a link between diet and our brain’s current and future health.
The Alzheimer’s Society UK suggests a diet that includes whole grains, fruits, vegetables, and fish. They emphasize that maintaining good health over a lifetime is probably the best strategy to reduce dementia risk.
Interestingly, some researchers have noted a two-way connection between gut bacteria and anxiety. Diets low in fiber yet high in sugar have been correlated with worse sleep quality.
Rosemary, which has been associated with improved blood circulation in the brain, could potentially be beneficial for cognitive health.
A compound in rosemary shows promise for better dementia outcomes in mice
A study published in a journal found a connection between a compound, carnosic acid, from rosemary and the elimination of Alzheimer’s-related proteins in mice.
Carnosic acid has previously been recognized for its protective effects on the brain, along with its anti-inflammatory properties, though it can be tricky to stabilize in its pure form.
To address this, researchers developed a more stable synthetic version known as diAcCA.
In tests on mice suffering from amyloid plaques associated with Alzheimer’s, the harmful proteins were notably reduced, and no negative side effects were detected.
The lead author expressed optimism, saying, “We conducted multiple memory tests, and all showed improvement with this drug. It didn’t just slow the decline; it allowed for nearly complete recovery.”
Other potential benefits of rosemary
A randomized trial in 2024 revealed that rosemary might help enhance memory, reduce anxiety and depression, and improve sleep quality in college students.
A 2020 study also indicated that Japanese men dealing with mood issues experienced improved mood and sleep after four weeks of rosemary extract.
Additionally, drinking rosemary tea appears to be linked to lower levels of depression and anxiety markers in healthy volunteers.
Moreover, a paper from 2021 connected aromatherapy with lavender and rosemary to better cognitive function and reduced anxiety in elderly diabetics.
More research is definitely required to define the ideal types and amounts of rosemary needed to harness these benefits, but for now, this surprisingly nutrient-rich herb might just enhance your mood and help with sleep and stress.
