Coffee – Yet More Good News!

Coffee protects the liver against alcoholic cirrhosis [1] and there is previous animal and limited human evidence that it preserves cognition in older age.[2] Data on this point have now emerged from ten years follow-up of nearly 6,500 enrolees in the Women’s Health Initiative Memory study.[3] Women consuming above median caffeine intake experienced about a 25% reduction in dementia (p=0.04) or cognitive impairment (p=0.005). Surprise, surprise, caffeine modulates synaptic plasticity, discussed previously in your News Blog.[4-6]
