Few epidemiological studies have been conducted that have incorporated clinical evaluations of Gulf War veterans with unexplained health symptoms and healthy controls. We conducted a mail survey of 2022 Gulf War veterans residing in the northwest United States and clinical examinations on a subset of 443 responders who seemed to have unexplained health(More)
Approximately 80,000 of the 697,000 American men and women who were stationed in SW Asia during the Gulf War (GW) report unexplained illness consisting of symptoms of persistent fatigue, cognitive difficulties, such as mild memory loss, diffuse muscle and joint pain, gastrointestinal symptoms, skin lesions, and respiratory problems, among others.(More)
About 80 per cent of perinatal deaths are associated with low birthweight. Mothers' prepregnancy weight for height is correlated with birthweight, but this is only a crude indication of the close connection between low birthweight and maternal consumption of energy, protein and a range of other nutrients before and around the time of conception.

The first dramatic effect of food shortage is upon fertility. The authors attribute the marked decline in fertility in Dresden following the second world war to a sudden reduction in food supplies from the formerly occupied territories following the fall of the German armies. There were also epidemics of low birth weight, miscarriage, and congenital(More)
British recommendations (DRVs and RNIs) include hardly any increments for pregnancy. British recommendations for protein are likely to cause unsatisfactory birthweight. What is the normal nutrient intake in pregnancy of healthy women? What evidence is there of special requirements for folate, iron, magnesium or iodine? New recommendations for nutrient(More)
British adults who were disabled by defective vision were estimated to number 1.668 million in 1988. Cataract is a most important cause of disability and blindness. Cataract develops earlier in life in populations with low income and inferior education. Cataract was shown to be associated with riboflavin deficiency in animals in the 1930s and subsequently(More)
Vitamin B12 deficiency damages nerve cells and aggravates nervous system disorders even in the absence of evidence of anaemia. Prevalence of B12 deficiency increases with age especially over 65 and is frequently associated with Alzheimer's disease. Recent American surveys record a higher prevalence of B12 deficiency and of undiagnosed and untreated(More)
7.2 per cent of babies born in England and Wales in 1986 had birthweights below 2,500 g. Low birthweight and hypertension are associated. European trials have reported that oral supplementation with physiological amounts of magnesium during pregnancy reduces pregnancy hypertension and also miscarriage, preterm birth and fetal growth retardation.
