Although the avocado is from South America, it has naturalized itself here , in south India. It is known as butterfruit here.The Aztecs considered it a fertility fruit. The avocado trees in the neighbourhood are now full of fruit. They don't ripen on the tree, but have to be plucked when mature, and ripened in the house.
Avocado lowers the LDL(bad) cholesterol, and triglyceride levels and increases the HDL (good) cholesterol levels.It has lots of potassium and vitamins, and fat.
In India, it is made into nutritious milk shakes.
An interesting thing about avocado is that squirrels don't attack it. Maybe, because it is mildly toxic to smaller animals.
