Protecting against radiation and reducing cholesterol are well-known benefits of green tea. According to a recent study by Japanese scientists published in the weekly journal “Clinical Nutrition” (USA), drinking 2 to 3 cups of green tea daily may help prevent dementia in the elderly.
This study was conducted with individuals over 70 years old. The results showed that those who consumed 2 to 3 cups of green tea daily had memory performance that was twice as good compared to those who drank only 1 cup or none at all.

Researchers explain that this is linked to catechins, the primary component found in green tea. Catechins have antioxidant properties and eliminate some harmful free radicals in the body, effectively preventing and improving dementia in older adults.
Notably, green tea contains a significant amount of easily soluble carbolic acid that quickly increases. Therefore, once inside the body, the catechins can penetrate the physiological barriers, rapidly dispersing to the central nervous system and other organs, fulfilling their disease-preventing functions.
Not only for the elderly, but even for the general population, those who drink more than 3 cups of green tea daily show higher memory, concentration, and fluency compared to those who drink little or no tea. For instance, when comparing the number of elderly individuals with dementia globally, Japan has a significantly lower rate compared to Europe. This is largely due to the long-standing habit of drinking green tea among the Japanese, which helps them prevent this chronic disease early on.
It’s also essential to note that while black tea and oolong tea are also derived from tea leaves, they do not possess the same anti-aging effects on mental acuity in the elderly as green tea does.
