A person’s intelligence is actually influenced by two main factors, namely genetics (genetic or congenital) or environmental factor. Parents whose children will tend to generally intelligent smart anyway, especially with the environment that supports the development of intelligence since still in the womb, infancy, and toddlers.
So even though both parents smart, but if the environment does not provide the basic needs for the development of intelligence, the intelligence potential can not develop optimally.
One of the basic needs of intelligence development is through nutrition received since the child still in the womb through the mother’s food intake. While after the baby is born, breast milk is rich in necessary nutrients to support brain growth process.
However, that breast milk contains all the necessary nutrients the child, the mother should eat a nutritious and balanced diet every day during pregnancy and lactation. Mothers also need to eat foods rich in protein, such as fish, meat, eggs, tempeh, tofu, and skim milk, and eat more vegetables and fruits.
Some of the nutrients in breast milk that play a role in brain growth, namely:
Essential fatty acids
Breast milk is a source of essential fatty acid, is a fatty acid that needs to be met from outside the body. Essential fatty acids in the baby’s body will be converted into DHA (dokosaheksanoat acid) and AA (arachidonic acid). Of fat in the milk serves as an energy source. In addition, a small portion of fat that serves as a micronutrient essential for growth and brain development. Lipids as micronutrients contained mainly in the form of phospholipids.
During pregnancy and early life has generated approximately 6-10 thousand synaptic connection between nerve cells. Basic material for the formation of this synapse is the essential fatty acids in breast milk. Therefore, mental development and intelligence of children depend on adequate supplies of essential fatty acids in the critical period.
If the baby’s body is getting enough DHA through her mother’s breast milk, then the process of brain formation and maturation of nerve cells in the brain will go well.
The basic components of proteins are amino acids that form the structure of the brain function. Several types of specific amino acids, ie taurine, tryptophan, and phenylalanine, a substance that serves as a conductor or messenger (neurotransmitter). Protein contained in milk, about 1.2 grams per 100 ml of milk.
Vitamin B Complex
Several types of B vitamins needed for brain growth is vitamin B1, vitamin B6, and folic acid (vitamin B9). When needs are not met, then there will be disruption to the growth and function of the brain and nervous system.
Choline is forming a kind of neurotransmitter, called acetylcholine. Choline is also part of lecithin, a phospholipid that is abundant in the brain as forming nerve cell membrane.
Iodine, iron, and zinc
Iodine is required for the formation of the hormone thyroxine, which kind of hormone that is needed in the formation of protein to aid the process of brain growth. While iron is needed in the process of myelin formation. Iron stored in a variety of brain tissue during the first 12 months since the baby was born. Zinc is part of the approximately 300 types of enzymes that help the cell division. Zinc deficiency in the brain may lead to impaired function of the brain called ADHD (attention deficit hyperactive disorder).
