Researchers in 2005 proposed that Alzheimer's disease be classified as "Type 3 diabetes" based on similarities between the two conditions. Both involve insulin resistance - in Alzheimer's, insulin resistance occurs in the brain rather than peripheral tissues. A high-carbohydrate, high-sugar diet can lead to insulin resistance in the brain and increased risk of Alzheimer's through inflammation and brain cell damage over time. Extra virgin coconut oil, which contains medium-chain triglycerides, shows promise in reducing Alzheimer's risk by providing an alternative fuel for the brain and controlling insulin resistance.
