Coffee is no longer the nutritional bad guy it used to be. There’s scientific talk that it might reduce the risk of diabetes; possibly also endometrial cancer. Apparently it can reduce the damage associated with a fatty liver, but the good news this week is that moderate coffee intake can significantly slow the onset of Alzheimer’s disease.
Mild cognitive impairment (MCI) is an early sign of Alzheimer’s disease. This study which is about to be published in the Journal of Alzheimer’s Disease looked at 124 people suffering from MCI (aged between 65 and 88). Normally a percentage of these would be expected to develop Alzheimer’s within a few years, however nobody in the group who maintained a blood caffeine level above 1,200ng/ml went on to develop Alzheimer’s over a 2-4 year period. Coffee was the main or only source of caffeine.
Neuroscientist, Chuanhai Caoa, says “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”.
