Low birth weight and brain disorders..

The prevalence of low is greater than in

1953

Last century, science and food policy focussed on protein and body growth.

H. Sapiens is about brain growth not body growth.

.

Note the similar sizes of the brain case of the 1 year old and his mother

Note the sizes of the hands.

The brain is the first priority on H. sapiens

Body = proteinBrain = lipids.

Priority for food policy is the brain specific lipid.

During the 1st trimester :

• significant correlation between BW and maternal intake of

many micronutrients, notably thiamin, niacin, Mg and Fe

• there was a strong social class gradient with both nutrient intakes

and birthweight.

diet and the dimensions of babies in a population of London Women. Nutr. Health 9: 303-315.

Mothers of LBW (<2.5kg) babies :

• had significantly lower intakes of almost all vitamins and

minerals than mothers of babies weighing 3.5-4.5kg

• had vitamin and mineral intakes well below the RNIs

• Lower the weight, the lower the plasma choline phosphoglyceride AA.

• Lower the gestational age the lower the DHA

• Both correlate with head circumference.

• The Bax – Little Foundation - European

Cerebral Palsy study using MRI at 4 years of

age showed the lesions were all prior to the

expected date of birth.

• Therefore they were not due to obstetric

mishap.

• 2o% had no MRI evidence of lesions and were

therefore due to connectivity as seen in the

neurogenesis study of DHA deficiency.
