As with most aspects of science, there is typically the protagonist and the antagonist. One of the great examples here is that of supplementation.

The argument used by many people in the conservative medical world is that if you consume a good diet, there is no need to supplement because you are not deficient in any of the vitamins, minerals and trace metals that you will obtain from natural, nourishing food.

Although, I totally agree that eating good quality food is an important principle of good health, there are a number of factors in our modern world pointing to the…


A study reported at an American Heart Association meeting in California a few years ago which was conducted in Utah in the United States examined the records of 62,000 people who suffered either a heart attack or stroke between 1999 and 2013.

The researchers reviewed whether they were taking statins and the dose and then monitored them for a period of three years or until their death.

Those patients who were prescribed statins had a reduced risk for a further event such as a heart attack, stroke, revascularisation or death by 25%. …


Recently, during one of my regular Melbourne radio segments, I received a call from a 47-year-old tradesman asking advice about his severe, knee osteoarthritis. After years of working on building sites, both his knees have severely degenerated to the point where he is now in considerable pain, but, like all of us – he has to earn a quid.

Because he is far too young, as it is suggested that knee replacements have around a 15 to 20 year use by date and also the fact that the recovery time for him to be able to get back to normal…


Despite being presented with scientific facts, not even debatable, there is still this lunatic fringe of anti-vaxxers and many people who remain vaccine hesitant, obtaining all of their information from some form of social media and not health experts who rely on science published in peer-reviewed journals.

All of the anti-vaxxers were not alive when children would die in infancy from serious illnesses such as diphtheria, whooping cough and tetanus, as a few examples or be permanently disabled from conditions such as polio.

The widespread vaccination programs of the last few decades have seen the vast majority of children kept…


With just over 3000 active cases from the Delta variant of the coronavirus in Australia at present, it doesn’t appear that this will be fizzling out, in the near future. Every day, we hear the statistics around the new cases which, although not markedly increasing, are staying concerningly around the 200 mark, but, thankfully over the past two days, the cases active in the community have only been in the 20s.

Some disturbing evidence from the CDC in the US has suggested that there is a 10 times higher viral load in the airways of people infected with the Delta…

As I write this article, half of Australia are in lockdown, which is approximately 12 million people. Hopefully, what I’m about to say will bring some calm and common sense to this crisis affecting so many people’s lives in our Australian community.

n New South Wales alone, it has become a communal habit at 11 am to listen to the “Gladys sweepstakes” on radio or television. We anxiously await the daily case numbers and continue to hear inflammatory language such as surging cases, the deadly virus etc., etc.

But, we must ask ourselves the question: are the cases really…


I am writing this article on Saturday, July 10 2021, mentioning the date purely because a week is a short time in the COVID-19 pandemic.

You’d have to be living under a rock not to be aware that a significant proportion of the New South Wales population is in a severe lockdown because of the recent outbreak of the Delta strain of the coronavirus.

Greater Sydney, the Central Coast, the Blue Mountains, Wollongong and Shellharbour are all in lockdown with stay at home orders, apart from the listed circumstances of buying food, exercise, attending medical appointments or different aspects of…

With the increasing rollout in Australia of the COVID-19 vaccine, evidence is emerging from around the world regarding potential problems with the vaccine. Unfortunately, this is not only fuelling the fire of the uninformed, unscientific anti-VAXXERS but is also increasing the number of people who are vaccine hesitant.

It is my opinion that either of the aforementioned groups are missing the point. Until either 70% of the population is either exposed to the coronavirus itself or vaccinated, we cannot possibly achieve herd immunity. Thus, without a widespread vaccination program, the more sick, vulnerable and elderly populations are still at risk…

Dupuytren’s (pronounced du-pwe-TRANZ) contracture is a hand deformity that usually develops over years.

It is more common in people from the north of Europe and those of Northern European descent and has been named “Viking disease” because it is more common in this population. The prevalence of diagnosed Dupuytren’s disease is 1% of the population but is seven times more common in surveys asking people about their hand pain (1). The contracture is three times more likely to affect men than women, and the age of the first presentation is usually between 50 and 70 years old (2).

There is…


The recent Royal Commission into Aged Care in Australia has released four basic recommendations.

Image source: Unsplash.com, Dominik Lange
  1. There is a strong need for a new Act that should determine the rights of older people, including their entitlement to care and support based on their needs and preferences.
  2. The system needs stronger governance to ensure the rights of the elderly.
  3. Age care workers need better conditions & training.
  4. More funds should be made available for the Aged Care sector.

Although I agree with all these recommendations, I believe this very expensive exercise of having the Royal Commission in the first place & then implementing…
