Our earliest ancestors lived in tropical and sub tropical climates which was prevalent throughout the world.
Humans ate mostly fruit year round.
Fruit is a very concentrated cocktail of healthy chemicals.
That is because fruit is the reproductive mechanism of many plant species.
Fruit is a great source of glucose.
Glucose is a simple form of sugar that serves as fuel for the body.
It is produced when carbohydrates are broken down in the digestive system.
Glucose makes up 60 of the brain.
And helps determine how we perceive reality in the neo cortex.
