You may have seen a lot about our need for fats because the brain is made up of mostly fat. What are the myths, and what is the science (i.e. the facts) here? 

Yes, when you take out the water- what is left in the brain, called the dry weight, IS made up mostly of fats- about 60%. It is considered to be a high fat organ. 

So….that makes fat really important, right? 

Well….except for the fact that the brain is about 80% water, depending where you read. The dry weight is one thing- but our brains are not dry and do not function in a dry environment. Being 80% water means…actually, they are mostly made up of water, not fat at all.
