It was reported in the news today that scientists have found a gene in breastmilk called FADS2. It effects the way the body processes fatty acids in the diet.
Previous research has shown that long chain polyunsaturated fatty acids (Pufas) accumulate in the brain during the first months after birth. They are present in human breast milk, but not cow’s milk, and children.have recently been added to infant formulas, as the importance has become more recognised.
Scientists believe that Pufas are important to childhood brain development because they are essential for the efficient transmission of nerve messages and help to promote the growth of nerve fibres.
A long term study carried out in the UK and New Zealand shows that breast fed children can have IQ scores about 7 point higher than bottle fed children on average.
Studies followed the progress of more than 3,000 children in the UK and New Zealand. AOL news explains “One, the Dunedin Multidisciplinary Health and Development Study, tracked the health and behaviour of 1,037 children born in New Zealand from the age of three.
IQ was tested at ages seven, nine, 11 and 13 and DNA samples obtained from 97% of the participants when they reached adulthood.
The Environmental Risk (E-risk) Longitudinal Twin Study monitored the development of 2,232 British children, all twins, whose IQ was measured at age five. DNA was taken for analysis from 2,140 of the In the New Zealand study, 57 per cent of the children were breast-fed and IQ scores ranged from 55 to 147. A total of 48 per cent of the UK children were breast-fed. Their IQ scores ranged from 52 to 145.
The DNA samples revealed that 90 per cent of the children in the two study groups had at least one copy of the “C” version of FADS2 which yielded higher IQs if they were breast-fed. But breast-feeding had no effect on the 10 per cent of children who had “G” versions of the gene.
The findings appear in the journal Proceedings of the National Academy of Sciences. They go some way towards settling the “nature versus nurture” debate over what has the greatest influence on child intelligence.”
I am not convinced there really needs to be a ‘nature versus nurture’ debate. Surely a child’s intelligence is effected by both nature and nurture.
I have Sheila Kippley’s book on breastfeeding- see above. She explains the massive health benefits to both mother and child, benefits that have finally been recognised by the World Health Organisation. They now recommend breastfeeding a child until he is 2yrs if possible.

“…{Breastfeeding] benefits the child and helps to create the closeness and maternal bonding so necessary for healthy child development. So human and natural is this bond that the Psalms use the image of the infant at its mother’s breast as a picture of God’s care for man…”
Pope John Paul II

Kippley writes from the foundation of Pope John Paul the Great’s Theology of the Body and the Church’s teaching on the sanctity of marriage and the dignity of women. Her book is particularly useful because it offers practicle advice and encouragement along with the theology and scientific facts about breastfeeding.
It is not just that a mother’s milk is best for the child and actually changes and develops to give the changing and developing child the very best for that time; nor the fact that breastfeeding helps prevent breast cancer-but that it is part of the bond between mother and child.
And finally as my beloved husband points out-it’s free.
