I wanted to share the information I got from reading the translation of H. Maaruf bin Haji Abdul Kadir ( Malaysian nationals professor ) from the University of Massachusetts USA on research conducted by DR Stephen Carr Leon. This research is about the development of quality of life for the people of Israel of Jews.
Why The Jews, on average smarter ? Studies conducted to get the facts as follows :
Apparently, if a pregnant Jewish, then the mother immediately increase the activity of reading, singing and playing piano and listening to classical music. Not only that, they also soon begin to learn more math intensive and also purchase more books on mathematics, study it and if things are not well known, they did not hesitate to come to other people who know math to learn it. All of it did for her baby who was still inside the womb.
After the child is born, the mother is breastfeeding her baby, they choose to eat more nuts, dates and milk. During the day, eating bread with a fish without a head and a salad. Fish flesh is considered good for the brain and the head the fish should be avoided because they contain chemical that are bad for the child's brain growth. Besides the mother must eat a lot of fish oil ( code liver oil ).
