　　FEED THE BRAIN , BUT LESS SUGAR

　　While no single factor has been identified as the cause of Alzheimer’s it is thought that lifestyle choices , Such as diet exercise and sleep habits can all have a significant impact on the risk . In fact , research by the Albert Einstein College of Medicine has , so far , suggested that lifestyle changes related to healthy ageing looks “more promising than drug studies”.

　　For the last decade or so , researchers have been exploring the link between our modern diets and the increasing prevalence of Alzheimer’s, specifically the connection between sugar and the disease. A study published in the New England Journal of Medicine demonstrated that even a mild elevation of blood sugar is associated with an elevated risk of dementia.

　　Previous research had shown a higher risk for diabetics in developing Alzheimer’s more recent research has shed further light on this, finding an intricate link between insulin resistance and the brain. Our bodies produce insulin that is necessary for the survival of brain cells , but this process goes awry when a toxic protein, called ADDL, removes receptors form these cells and renders them insulin resistant . As the ADDLs accumulate, our memory can begin to deteriorate.

　　So ,what should we be feeding our bodies ti give our brain the best change? A diet low in sugar and carbohydrates and high in healthy fats is essential . Opt for “real” food above processed options and try to keep added sugar levels to a minimum (ideally between 15 and 25 grams a day) . Add plenty of good fats like avocados, raw nuts and coconut and other nut oils to the diet and try a high-quality probiotic to optimize the flora in the gut.
