You can’t detox your body. It’s a myth.

Posted 22 December 2014

From the Guardian  5 December 2014

So how do you get healthy?
There’s no such thing as ‘detoxing’. In medical terms, it’s a nonsense. Diet and exercise is the only way to get healthy. But which of the latest fad regimes can really make a difference? We look at the facts.

BMJ study blasts “Dr. Oz” and “The Doctors”

Posted 21 December 2014

Canadian researchers have concluded that the advice given on “Dr. Oz Show” and “The Doctors” is untrustworthy. [1] After evaluating 80 randomly selected statements made on each show, the researchers concluded:

  • For recommendations in The Dr Oz Show, evidence supported 46%, contradicted 15%, and was not found for 39%.
  • For recommendations in The Doctors, evidence supported 63%, contradicted 14%, and was not found for 24%.
  • “Believable” or “somewhat believable” evidence supported 33% of the recommendations on The Dr Oz Show and 53% on The Doctors.

BetterYou Transdermal Magnesium

Posted 07 December 2014

BetterYou Transdermal Magnesium, although a British company, is marketing their product in South Africa. They claim that using the product will assist relieving stress (sheer nonsense), and that the claims of transdermal absorption is supported by three studies. In fact, the first was conducted on dead pig’s ears, the second by the discredited test called hair analysis, and the third, a study that is pending and has not yet been conducted. Will the study confirm efficacy for the product’s absorption? Who knows, unlikely, but let us see the results.

However, in writing to the owner of the company, he stood by his website claims and did not allude to the fact that the UK ASA had received a complaint, had evaluated the evidence, and threw it out!

Yes, the UK ASA said the claims are not supported by the evidence!

The impact of the Consumer Protection Act on pharmacists

Posted 02 December 2014

This article was published in the South African Medical Journal (SAMJ). Although specifically addressing this issue to health professionals, and in particular with reference to pharmacists, it has pertinence to every consumer and hence we are reposting the article here.

There is some irony in that the one author, Prof K du Toit, supported the claims for Antagolin, a product containing ingredients that have never been shown to have influence on the claims being made, and that was tested on South African consumers without ethical approval or informed consent being obtained from those who were studied. A big mistake! The ASA ruled against the claims for the product.
