Experts recommend cold-pressed, organic, virgin, non-hydrogenated coconut oil for preventing Alzheimer's disease and providing improvement for patients who already have the disease, according to Alzheimers.net. A study from the University of Oxford suggested that the effects are temporary but do result in improved cognitive function.
One theory to explain the benefit of coconut oil for cognitive function is that the oil boosts the level of ketones in the body and that ketones are important for maintaining brain health, notes Alzheimers.net. It is important to keep coconut oil refrigerated as it becomes a solid between 65 and 75 degrees Fahrenheit. One way to ingest it is to stir it into a bowl of oatmeal or a cup of coffee, but it also works well in many recipes.
