1. From Great Grandma to You! Susan Murphy, a researcher at Duke University, studies links between a mother’s diet and chemical exposures during pregnancy with the child’s later health. She and others have established that the womb is the antithesis of Las Vegas; what happens there not only doesn’t stay there, it can influence a child’s health for life. Now animal studies and a smattering of human data suggest prenatal effects could reach farther down the family tree. The vices, virtues, inadvertent actions and accidental exposures of a pregnant mother may pose health consequences for her grandchildren and great grand children, and perhaps even their offspring. Scientists have long known that radiation or certain chemicals can cause typos in a developing fetus’s genome – his or her genetic instruction book. Such mutations can get passed along to future generations in the DNA of sperm or egg cells. While exposure to sex hormones or a high fat diet in the womb doesn’t directly change or damage DNA, those sorts of exposures can induce scribbling in the genomes margins that can be passed down.

The resulting health effects are not produced by altering DNA itself.

When those changes are inherited, scientists have found the implications can be staggering. Part of your risk of disease may be determined by what your great grandparents ate, not just the genes they have passed on. Some researchers even believe that the long lasting effects of these chemical marks helped shape human evolution.

2. Diagnosing the Wrong Deficit Vatsal G. Thakkar, a clinical assistant professor of psychiatry at the N.Y.U. School of Medicine, states that many theories are thrown around to explain the rise in the diagnosis and treatment of A.D.H.D. in children and adults. According to the Centre for Disease Control and Prevention, 11 percent of school-age children have now received a diagnosis of the condition. I don’t doubt that many people do, in fact, have A.D.H.D.; I regularly diagnose and treat it in adults. But what if a substantial proportion of cases are really sleep disorders in disguise? For some people - especially children - sleep deprivation does not necessarily cause lethargy; instead they become hyperactive and unfocused. We all get less sleep than we used to. The number of adults who reported sleeping fewer than seven hours each night went from some 2 percent in 1960 to more than 35 percent in 2011. Sleep is even more crucial for children, who need delta sleep — the deep, rejuvenating, slow-wave kind — for proper growth and development. Yet today’s youngsters sleep more than an hour less than they did a hundred years ago. And for all ages, contemporary daytime activities — marked by nonstop 14-hour schedules and inescapable melatonin-inhibiting iDevices — often impair sleep. A number of studies have shown that a huge proportion of children with an A.D.H.D. diagnosis also have sleep-disordered breathing like apnea or snoring, restless leg syndrome or non-restorative sleep, in which delta sleep is frequently interrupted. One study, published in 2004 in the journal Sleep, looked at 34 children with A.D.H.D. Every one of them showed a deficit of delta sleep, compared with only a handful of the 32 control subjects. But it’s also possible that A.D.H.D.-like symptoms can persist even after a sleeping problem is resolved. Consider a long-term study of more than 11,000 children in Britain published last year, also in Pediatrics. Mothers were asked about symptoms of sleep-disordered breathing in their infants when they were 6 months old. Then, when the children were 4 and 7 years old, the mothers completed a behavioral questionnaire to gauge their children’s levels of inattention, hyperactivity, anxiety, depression and problems with peers, conduct and social skills. The study found that children who suffered from sleep-disordered breathing in infancy were more likely to have behavioural difficulties later in life — they were 20 to 60 percent more likely to have behavioural problems at age 4, and 40 to 100 percent more likely to have such problems at age 7. Interestingly, these problems occurred

even if the disordered breathing had abated, implying that an infant breathing problem might cause some kind of potentially irreversible neurological injury.

3. Quick food Facts It seems many Australians enjoy a glass of milk. The average consumption per person is 230kg. That is almost THREE times the world average and more than twice that of New Zealand! Our Kiwi neighbours eat more vegetables than the average Australian – more than 200kg of starchy root and other vegetables compared with our 153kg! Prawns aren’t the only sea creatures Australians throw on the Barbie. Seafood consumption is about 25kg per person per year, above the world average of 17kg but less than half that of Japan.
