Now softdrinks are good for you: "Fizzy soft drinks may rot your teeth but new research suggests the sugary refreshments also boost the memory. Contrary to conventional health messages, which have branded the high-sugar drinks as unhealthy, researchers in Scotland found that people who consumed 50g of sugar - just over the amount in one can of soft drink - could boost memory retention by almost one-fifth. Neuroscientists from Glasgow Caledonian University said the effects might also help combat dementia in the elderly - and might eventually lead to better ways of treating memory problems in old age".
