Interestingly, there was not one certain tea that provided more benefits than the others. Researches found that health benefits weren’t limited to one specific tea.
The freshly brewed leaves of other herbal teas like black tea, green tea, and oolong tea, were all shown in this study to have neuroprotective effects.
Let’s take a dive into some of the most popular teas and discuss their brain-boosting benefits!
1. Green Tea
Green tea is derived from the leaves of the Camellia Sinensis plant. as one of the healthiest teas in the world. It contains antioxidants to promote healthy aging and reduce the risk of chronic disease.
Green tea also can boost your metabolism, promote fat loss, and fight fatigue.
Green tea has polyphenols to reduce inflammation in the body and improve cognitive function. It also contains L-theanine which helps relaxation without drowsiness.
Almost half of the green tea leaves are accounted for by catechins. The most abundant catechin in green tea is called epigallocatechin gallate (EGCG).
While some attribute EGCG in green tea to the decreased risk of cognitive decline or cognitive impairment, no studies have been done at this time to suggest this.
Although more studies should be done to have robust evidence, one systemic review of several cohort studies supported the hypothesis of green tea consumption reducing the risk for Alzheimer’s disease, mild cognitive impairment, or cognitive impairment.
2. Black Tea
Similar to green tea, black tea also comes from the Camellia sinensis plant and has compounds that may lower the risk of dementia.
It also has polyphenols, flavonoids, and other antioxidants that can fight free radicals that may be protective against chronic disease.
In addition to a lower risk of dementia, one study also found that black tea consumption lowered LDL cholesterol (the bad cholesterol!)
In fact, one study from England’s University of Newcastle found that both black tea consumption, as well as consumption of green tea, may lower the risk of Alzheimer’s disease.
3. Rosemary Tea
While many consider rosemary as a staple cooking ingredient, it also makes for a lovely cup of warm tea.
While more research is needed, some studies suggest that a low dose (750mg) of rosemary intake was associated with improved memory speed.
