Coconut oil improves memory by supporting the health of brain neurons. It provides energy to neurons so that they can work.
Coconut oilalso helps protect neurons by reducing inflammation and oxidative stress. There's a lot of talk right now about coconut oil being good for the brain.
The main argument is that coconut oil is rich in medium chain triglycerides, or MCTs, which are metabolized a little differently than most types of fat. The MCTs in coconut oil break down into ketones, which can be used by brain cells as fuel. The idea is that supplying the brain with a little extra fuel could make it work better. Coconut has been called a “potential cognitive enhancer” when it comes to Alzheimer's disease, and it's all due to those ketones.
Some believe that coconut oil may act as an alternative energy source for the brain. However, there is not enough scientific evidence to know if this is the case. Coconut oil is extracted from coconuts, but you can see that it's different from other vegetable oils, as it's a white solid at room temperature. This means that simply adding coconut oil to the diet would not provide brain cells with an alternative energy source.
Researchers believe that the brain cells of people with dementia have problems with the way they produce energy from glucose, which led to the theory that coconut oil could compensate for this situation. There have been some claims that coconut oil could be used as a treatment, or even a cure, for Alzheimer's disease. Not enough people were enrolled in the trial for researchers to fully understand if coconut oil has any benefits for people affected by dementia. That said, if the reason for using coconut oil is to lower high cholesterol levels, other options, such as fish oil, may be a better option.
There is currently no evidence to show that coconut oil plays any role in preventing or treating dementia or its symptoms. In fact, most (65%) of the fat in coconut oil is a mix of different “medium chain triglycerides” (MCTs). Since most studies find that coconut oil involves the use of virgin coconut oil, it seems that this particular type of coconut oil may offer some distinctive health benefits. Coconut oil is used to allow a slightly higher level of carbohydrate intake, which makes it a little easier to follow a very strict diet, but it still prevents the body from using sugar from carbohydrates as its main source of energy.
So, just because coconut oil supplies ketones doesn't necessarily mean that the brain uses them for fuel. In addition, the entire diet must be taken into account when deciding if coconut oil is going to be useful or harmful to health, since both things can be depending on other types of fats that are consumed. This is another possible use of coconut oil for the brain, again due to its metabolism into ketones.
