Good and bad cholesterol and memory loss

Researchers from the French National Institute for Health and Medical Research and from University College, London have found that low levels of high-density lipoproteins (HDL or 'good' cholesterol) in middle age can increase the risk of memory loss and lead to dementia in later life. At 55 years old participants with low HDL cholesterol had a 27% higher risk of memory loss compared to those with high HDL. To raise HDL and lower low-density lipoproteins (LDL or 'bad' cholesterol) the American Heart Association recommends exercising regularly, eliminating hydrogenated fats from the diet, reducing saturated fats and eating more polyunsaturates.
