Coffee helps prevent Alzheimer’s disease

Drinking three cups of coffee daily could prevent people from having Alzheimer’s disease.

According to a study by American researchers, over 65-year-olds could avoid having the Alzheimer’s disease by keeping high blood caffeine levels by drinking coffee.

The research team examined the cognitive status of 124people aged between 65 and 88 who showed mild cognitive impairment (MCI) which is an early sign of the disease. Most of these individuals were expected to develop Alzheimer’s disease within a few years.

The MCI patients, with blood caffeine levels above 1,200 ng/ml, did not develop the disease over a 2-4 period with their main and wholly caffeine source being coffee.

Chuanhai Cao, a study lead author and neuroscientist, said: “These intriguing results suggest that older adults with mild memory impairment who drink moderate levels of coffee – about 3 cups a day – will not convert to Alzheimer’s disease – or at least will experience a substantial delay before converting to Alzheimer’s.

“The results from this study, along with our earlier studies in Alzheimer’s mice, are very consistent in indicating that moderate daily caffeine/coffee intake throughout adulthood should appreciably protect against Alzheimer’s disease later in life”.

However, Cao said that moderate coffee consumption will not completely protect people from Alzheimer’s disease.

He added: “However, we firmly believe that moderate coffee consumption can appreciably reduce your risk of Alzheimer’s or delay its onset”.

Since the past year, coffee has proven to be quite advantageous for human health.

In February, s study discovered that high caffeine levels in coffee could minimise the risk of advanced fibrosis in those with fatty liver disease.

Another study revealed that drinks full of caffeine could prevent the risks of womb (endometrial) cancer and diabetes.
