Lesson 2: Staying hydrated and ingesting fats will support your brain .

“Stay hydrated’’ is something we’ve probably heard more than once. And for a reason! The brain is made out of 80% water , and this special element is only one of the few ones allowed to pass the blood-brain barrier. In other words, water goes straight to your brain, as it is involved in the energy production process.

Not just that, but water is also responsible for the brain’s chemical reactions, for filling up the spaces between the cells, and for flushing out toxins. Drinking two liters per day can boost your brain’s performance by up to 30%! Therefore, make sure to invest in a quality water filter and stay hydrated.
