DNA, epigeneticsYou have had a long-standing deal with biology: whatever choices you make during your life might ruin your short-term memory or make you gain weight t or could hasten death, but they won’t change your genes — your actual DNA.

The answer lies beyond both nature and nurture. Bygren’s data — along with those of many other scientists working separately over the past 20 years — have given birth to a new science called epigenetics.

At its most basic, epigenetics is the study of changes in gene activity that do not involve alterations to the genetic code but still get passed down to at least one successive generation.

These patterns of gene expression are governed by the cellular material — the epigenome — that sits on top of the genome, just outside it (hence the prefix epi-, which means above). It is these epigenetic “marks” that tell your genes to switch on or off, to speak loudly or whisper. It is through epigenetic marks that environmental factors like diet, stress and prenatal nutrition can make an imprint on genes that is passed from one generation to the next.

But the potential is staggering. For decades, we have stumbled around massive Darwinian roadblocks. DNA, we thought, was an ironclad code that we and our children and their children had to live by. Now we can imagine a world in which we can tinker with DNA, bend it to our will.

It will take geneticists and ethicists many years to work out all the implications, but be assured: the age of epigenetics has arrived.

Baby boomers bounce badly into old age

November 14th, 2009

BABY boomers can expect to live long lives, but they won’t be healthy, according to new research showing they already suffer more disability than their elders did.

The study, to be published in January in the American Journal of Public Health, focussed on boomers aged 60 to 69 and found they displayed increasing disabilities over time.

In contrast, the researchers — with the University of California at Los Angeles and the University of Southern California — found that people between 70 and 79 years showed no significant increases in disability and, in some cases, exhibited fewer disabilities than did their parents.

The results, which will surprise many health-obsessed boomers, come on the heels of a study in The Lancet, reported last month in Weekend Health.

There, international researchers found that more than half the babies born since 2000 in developed nations such as Australia will live to 100 years or more if trends continue.

According to the leader of the California team, UCLA epidemiologist Professor Teresa Seeman, the findings hold “significant and sobering implications”.

She said: “If this trend continues unchecked, it will put increasing pressure on our society to take care of these disabled individuals.”

Live ten years longer - Summary - Article from:

WHETHER you’re a smoker or a stress-head, a few key lifestyle changes can reverse the health sins of the past.

If scientists developed a miracle pill that guaranteed to add 10 healthy years to your life, there would be a stampede from eager customers that would make January stocktake sales look tame.

Yet experts insist we already have the power to extend our life expectancy by more than a decade simply by tweaking our lifestyles, quitting bad habits and taking up positive measures.

There’s no magic-bullet solution. But simple changes can yield maximum results. And the good news is even after years of toxic living, you can make a big difference by acting now.

MAINTAIN A HEALTHY DIET (+3 to 13 years)

Good nutrition is vital to keep our DNA healthy and therefore stay alive longer, according to Dr Michael Fenech, principal research scientist at CSIRO’s Food and Nutritional Sciences in Adelaide.
GET SPIRITUAL (+4 to 7 years)

Research shows that those of us with a religion, faith or spirituality tend to live longer.


EXERCISE REGULARLY
(+4 years)

Regular  physical activity can boost your prospective lifespan by three or four years, Devlin says.

“For general health benefits, you need 30 minutes (of activity) a day,” she says.


STRESS LESS
(+3 years)

Relax and don’t sweat the small stuff - it can add up to three years to your life.
QUIT SMOKING (+13 years)

One of the most effective ways to add years to your life is to quit smoking - the earlier, the better, says Liz Devlin, director of the Centre for Health Advancement at NSW Health.
LOSE EXCESS WEIGHT (+7 years)
Staying within a healthy weight range is an established life preserver. This means maintaining a body mass index of about 18.5 to 25 for most adults.

Overweight or obese people can expect to die an average of seven years earlier than those of normal weight, warns Liz Devlin.

DRINK IN MODERATION (+10 to 15 years)
As most of us know, the odd glass of red wine can be beneficial to our health. But when that glass turns into a bottle, the effect is reversed.

Alcohol dependence can shorten our lives by a whopping 10 to 15 years by making us more susceptible to heart disease, cancer, accidents and suicide, according to a study published in the Journal Of Korean Medical Science last year.

EU rules fluoride a medicine

July 27th, 2009

By - Peter Morley

FLUORIDE opponents have been handed a new weapon in their fight to reverse the Bligh Government’s mass medication program.

The European Court has ruled that fluoridated water must be treated as a medicine and cannot be used in the manufacture of consumable products.

While the immediate impact is on Continental manufacturers it will also apply to Australian companies which supply Europe with goods.

To gain entry they will have to prove their product was made with water that was not fluoridated.

The trade impact is being assessed by Austrade. and a spokesman said further information was being sought from its London and Frankfurt offices in a bid to assess the Australian implications.

“But it would appear the law seems to be interpreted in a new way which suggests that fluoride should be classified as medicine,” he said. “That means it cannot he added to food or liquor products.”

Queenslanders for Safe Water spokesman~ MacQueen said the ruling could “bust this whole issue wide open”.

NB/ I wonder if this would also apply to crops grown using fluridated irregation water???

What’s Wrong With the Australian Health System

July 27th, 2009

54 per cent of adult Australians and one in four children are now overweight or obese.
. ………….
If the trend continues, nearly three-quarters of the Australian population will be overweight or obese by 2020.
…………………………………………..
They are at risk of developing chronic diseases like diabetes, heart disease and cancer.
—————————————-
Almost four in five Australians have at least one long-term or chronic health disease.
……….    …..
Chronic health problems take up nearly 70 per cent of total health funding for diseases.
……….
In 2006-07, Australia spent 8.7 per cent of GDP on health and that will rise to 12.4 per cent of GDP by 2032-33.
———-
. The life expectancy of Aboriginal and Torres Strait Islander men and women is shorter, on average by  11. 5 years and 9.7 years respectively.
——-
Too many diagnostic tests, medicines and procedures that are performed are unnecessary inappropriate,  and even sometimes harmful
………………………………….
The number of avoidable adverse events in the nation’s hospitals each year is the equivalent to 13 jumbo jets crashing and killing all 350 passengers on board.
…………………….
Almost 10 per cent of hospital stays potentially preventable if timely and adequate non-hospital health care had been provided to patients with chronic conditions.
……………………………………….
Australians are now older and they five for longer  and an ageing population will put significant additional
demands on our health and aged care systems.

Conclusions: Tackling Obesities: Future Choices – Project Report FORESIGHT

July 17th, 2009

In recent years, Britain has become a nation where being overweight has become usual rather than unusual. The rate of increase in overweight and obesity, in children and adults, is striking. Obesity threatens the health and well-being of individuals and will place an intolerable burden on the Exchequer in terms of health costs, on employers through lost productivity and on families because of the increasing burden of long-term chronic disability.

Obesity is a consequence of abundance, convenience and underlying biology. It might also be viewed as the perverse outcome of constantly expanding ‘choice’. What is certain is that this epidemic of ‘passive obesity’ is unlikely to come to a natural end, i.e. without intervention. Obesity presents society with a number of tough choices about the relative importance of different goals and aspirations.


Obesity, like climate change, is a complex problem, but it is not insoluble. At present, the best scienti? c advice suggests that solutions will not be found in exhortations for greater individual responsibility nor in short-term fragmented initiatives.
Tackling obesity is fundamentally an issue about healthy and sustainable living for current and future generations. This is only likely to be achieved if there is a paradigm shift in thinking, not just by Government but by individuals, families, business and society as a whole. There is therefore an urgent need for leadership, vision and, above all, sustained commitment. The case for action can be strengthened by identifying potential synergies and complementarities with other policy goals, such as climate change, to provide multiple bene? ts. Alignment with these other issues is crucial if the prospect of the majority of the UK adult population being obese in less than 50 years, with its attendant costs, is to be prevented from becoming a reality. The UK has the opportunity to build on existing work and pioneer a new long-term and integrated approach that sets a global standard for success.

Australisa: Survey on Complementary Medicine

July 17th, 2009

Some interesting information published by the Journal of Complementary Medicine (July/August Issue) regarding a Morgan poll conducted in 2008.

The poll found that there is an increased amount of Australian’s using Complementary Medicine, exactly three-quarters of the population in fact. The poll used past survey results for their comparison and showed there has been a consistent rise in consumption of these types of products over the past eight years.

The magazine states, “Vitamin/mineral consumption since 2001 has declined 6% to 63%, that of herbal supplements more than halved from its height of 48%, while the use of nutritional supplements had leapt from 19% to 42%.” The Journal also found that men “are surprisingly keen CM consumers, with about half of every age group…taking a vitamin or mineral. Nearly half of men aged over 45 took nutraceuticals.”

Magnesium Benefits Your Blood Pressure

June 10th, 2009
Magnesium may reduce blood pressure in people with high blood pressure, according to new findings. The study adds to data from epidemiological studies that have reported more magnesium, potassium and calcium may reduce your risk of hypertension.

Researchers recruited 155 people to take part in a double-blinded, placebo-controlled, randomized trial. The subjects were randomly assigned to receive either daily supplements of magnesium oxide or a placebo for 12 weeks.

At the end of the study, no significant differences were at first observed. However, when the researchers looked specifically at hypertensives, significant decreases in both systolic and diastolic blood pressure were observed in the magnesium group.

Can we get sufficient micro-nutrients from diet alone?

May 18th, 2009

Dr Brian Liebovitz, editor of the Journal of Optimal Health - comments -

“There is not a shred of evidence thar diet alone can supply enough micronutrients to attain any level of health above adequate.  I’ve never seen a single study to support the concept that you can get everything you need for optimal health from a well-balanced diet.  This is due in part, to our asking the wrong questions.  Instead of nutrient deficiencies, as we’ve studied for so long - and as many nutritionists still study - we need to focus on supplemental nutrients. For only though supplemental nutrients can we achieve optimal health.”

“Consumers should demand evidence of success.  If it consists primarily of testimonials or other anecdotal evidence, view the program with suspicion?  - THE FDA Consumer

The problem is Carbohydrates

May 18th, 2009

Extract by Gary Taubes

“The problem is is the carbohydrates in the diet, their effect on insulin secretion, and this the hormonal regulation of homeostatasis - the entire harmonic ensemble of the human body.  The more easily digestible and refined the carbohydrates, the greater the effect on our health, weight and well-being…Consuming excess calories does not cause us to grow fatter..expending more energy than we consume does not lead to long term weight loss.. Fattening is caused by an imbalance—a disequilibrium in the hormonal regulation of adipose tissue and fat metabolism..Insulin is the primary regulator of fat storage.

When insulin levels are elevated, we accumulate fat in our fat tissues. When insulin levels fall we release fat from our fat tissues and we use it as fuel. By stimulation insulin secretion, carbohydrates make us fat..The fewer carbohydrates we consume, the leaner we will be.”
