WHY DOES THE BRAIN CONSUME THE MOST OXYGEN AND CALORIES ?

The brain contains up to 60% fat. It is the fattest human organ.

It makes up less than 2% of our body, but consumes about 20-30% of the calories in our food intake. Also the brain consumes 20% of all the oxygen entering our body.

For normal functioning of our brain, a person must breathe fresh air.
