Can Green Tea Really Prevent Alzheimer’s Disease?

Green tea continues to rank among the smartest additions you could make to your day. Study after study seems to demonstrate just how healthful green tea can be. The most recent of these studies suggests that drinking green tea every day can help reduce your risk of developing dementia.

The study looked at 1,000 older adults, in China, who drank at least one cup of green tea every day for 7 years. This group was about 50 percent less averse to cognitive decline than others of the same age who did not drink green tea every day.

Furthermore, the study says that people who carry the APOE4 gene have even greater benefit. This sub-group was 85 percent less likely to show loss of brain function. And this is important, of course, because the APOE4 gene has been linked with increased risk for Alzheimer’s disease, among other forms of dementia.

Alzheimer’s disease is easily the most common form of dementia today. It is known for destroying the sufferer’s memories as well as degrading many mental functions. It is also known to slow or hinder the ability to remember places, people, faces, and other details. It can even lead to dramatic shifts in personality and mood.

Unfortunately, we still do not know what causes Alzheimer’s disease. We do know that it is a neurodegenerative disease that can start very early in life but not present for several decades. We also know, as mentioned, that certain genetic profiles might be more predisposed to it.

Indeed, Alzheimer’s Research UK Head of Research, Dr. Rosa Sancho, notes, “Alzheimer’s is a complex disease with many risk factors involved, the most critical being aging. There is a growing body of evidence indicating that there are differences between men and women when it comes to Alzheimer’s risk, but research is continuing around exactly what drives this.”

This data, though, does not surprise Dr. Yuko Hara. She is the acting director of the Aging and Alzheimer’s Prevention unit at the Alzheimer’s Drug Discovery Foundation. This organization evaluates food, vitamins, beverages, and other supplements for the quality of brain health promotion. She reports, “Overall, I think we have about 40 reports and green tea may be one of the most promising things we’ve analyzed for brain health so far. Based on what I’ve seen, green tea does look the most promising.”
