Olive oil consumption can prolong life with dementia by 28%.

For the effect to manifest itself, you need to consume more than half a tablespoon of oil per day. Its action can be explained by the large amount of antioxidants in the composition. They can pass the blood-brain barrier - that is, affect the brain directly. There is also a version that the positive effect of olive oil indirectly affects the brain, healing the cardiovascular system.
