10 Medical Myths We Should Stop Believing. Doctors, Too.

Researchers identified nearly 400 common medical practices and theories that were contradicted by rigorous studies. Here are some of the most notable findings.

By Gina Kolata  – New York Times – July 1, 2019

You might assume that standard medical advice was supported by mounds of scientific research. But researchers recently discovered that nearly 400 routine practices were flatly contradicted by studies published in leading journals.

Of more than 3,000 studies published from 2003 through 2017 in JAMA and the Lancet, and from 2011 through 2017 in the New England Journal of Medicine, more than one of 10 amounted to a “medical reversal”: a conclusion opposite of what had been conventional wisdom among doctors.

“You come away with a sense of humility,” said Dr. Vinay Prasad of Oregon Health and Science University, who conceived of the study. Read the rest

BMJ 2019; 365 doi: https://doi.org/10.1136/bmj.l2251 (Published 17 May 2019)

The UK has seen a sharp rise in cases of toxicity from 2,4 dinitrophenol (DNP)-an industrial chemical often marketed as a fat burning or weight loss supplement-with 20 recorded cases and six related deaths in 2018, the UK National Poisons Information Service (NPIS) has said.1

Although DNP is labelled “unfit for human consumption,” it is still available and sold to people attempting to change their appearance, such as body builders and those trying to rapidly lose weight.

The spike in cases has prompted Public Health England to send a national warning to all healthcare professionals, telling them to “remain vigilant” for cases of DNP poisoning, and advise any patients suspected of consuming the toxic chemical to “discontinue use immediately.”

The notice, which was sent out to NHS trusts, GP practices, and community pharmacies, outlined Read the rest

So it’s not the ‘herbs’ doing the work…

The labels promise miracles: Fast Weight Loss! Eliminates Hunger! Burns Calories!

Now new research highlights how hundreds of brands of dietary supplements deliver so much kick from a modest blend of vitamins and herbs. The answer is many labels leave out one important ingredient: a hidden payload of pharmaceutical drugs and experimental chemicals.

A new analysis of 10 years of FDA records reveals that from 2007 to 2016, almost 750 dietary supplements were found to be contaminated with secret doses of totally unregulated drugs, including prescription medicines, banned and unapproved chemicals, and designer steroids.

Over 20 percent of these offending products contained more than one unapproved drug ingredient, and numerous contained a cocktail of clandestine chemicals – in two cases, as many as six unlisted ingredients.

Posted 10 September 2018

Higenamine is a stimulant that occurs naturally in a variety of traditional plant remedies. It has not been FDA-approved for any purpose, but is sold as an ingredient in supplement products.

In 2016, researchers made online purchases of 24 supplement products with higenamine as a labeled ingredient. Eleven of the products were marketed for weight loss, eleven were marketed as sports/energy supplements, and two were not labeled with a specific reason for use. Laboratory analyses revealed that the quantity of higenamine in the products ranged from trace amounts to 62 milligrams per serving with a margin of error of 6.0 milligrams.

Of the five products that listed a specific amount of higenamine on the label, none were accurate; the higenamine contents ranged from less than 0.01% to three times the quantity listed on the label. Clinical evidence regarding the safety and effectiveness of higenamine is lacking. Read the rest

Far too many protein supplements don’t live up to the claims on their labels and may be ineffective

Times Select – Wendy Knowler 27 August 2018

Most of SA’s bestselling whey protein products don’t live up to the protein content claims on their labels, or meet the amino acid levels stipulated the by health department.

The products (in powder form) are widely consumed by the sports and fitness community to help gain muscle and lose fat, and studies have shown they can be effective – but only if properly formulated.

As part of his Masters research in the field of pharmacy, Durban pharmacist Kiolan Naidoo, along with Varsha Bangalee and Rowena Naidoo, had an accredited lab in Pretoria analyse 15 of SA’s top selling whey protein products. They wanted to find out if they matched the protein analysis on their labels and whether they complied with Read the rest

Regulating the South African sport supplement industry: ‘Whey’ overdue

This article by K Naidoo, R Naidoo, and V Bangalee from the Discipline of Pharmaceutical Sciences, School of Health Sciences, Westville Campus, University of KwaZulu-Natal, Durban, and Discipline of Biokinetics, Exercise and Leisure Sciences, published in the South African Medical Journal, addresses the sorely needed regulation of the sports supplements industry.

Many sport supplements currently on the market are likely to be little more than placebos, containing either grossly under-dosed products or ingredients with no proven benefit. In a largely unregulated industry, consumers who complement their diet with supposedly safe and effective supplements, may be doing so to their own detriment, particularly when these are used in high doses or without medical supervision.

Posted 24 November 2017

The increasing availability of 2,4 dinitrophenol (DNP) on the grey market in the Netherlands has prompted the Dutch Food and Consumer Product Safety Authority (NVWA) to issue a warning against the substance.

“The packages were deliberately mislabelled as harmless food ingredients, such as chocolate powder, in an attempt to mislead customs. Research into the delivery addresses suggested that the DNP was intended for incorporation into food supplements with the final outlet being for use in gyms.”

“Supplement companies have definitely mastered one thing- how to market & sell stupid supplements. Unfortunately, only a handful of supplements work and are worth your money. Most of them, sadly, only dig a hole in your pocket. Apart from a handful supplements, a ton of them that are being sold today in the name of hypertrophy are completely useless. If you are a beginner, or even an intermediate lifter, chances are that you don’t need a lot of supplements that you may just be using. Here are some of them. “

Posted 10 September 2016

Food safety agencies in the UK have seized large quantities of DNP following a multi-agency effort, while Dutch authorities captured anabolic-androgenic steroids intended for use in sports nutrition supplements.

Despite being illegal for human consumption, the 2,4 dinitrophenol (DNP), remains on sale online and in some gyms. Commonly used as a diet aid, DNP has severe side effects and has been responsible for eight deaths in the UK since 2015.

Due to it’s alleged fat burning properties, however, the drug is still commonly sold online and at gyms, in the forms of capsules or powder.

“DNP can and does kill. We are relentless in pursuing those seeking to profit from the illegal sale of this toxic substances for human consumption,” said Heather Hancock, FSA chairman.

This article published in Business Insider, makes the following points (extracts):

“In the middle of the pregnancy, her mother had come down with tuberculosis. She’d contracted the contagious lung infection in her teens, and the illness came back despite preventative antibiotics and regular screenings. The cause: a popular herbal supplement called St. John’s wort. St. John’s wort is one of the most popular herbal supplements sold in the United States. But in 2000, the National Institutes of Health published a study showing that St. John’s wort could severely curb the effectiveness of several important pharmaceutical drugs — including antibiotics, birth control, and antiretrovirals for infections like HIV — by speeding up their breakdown in the body.”

““Consumers should expect nothing from [supplements] because we don’t have any clear evidence that they’re beneficial, and they should be leery that they could be putting themselves at risk,” S. Read the rest
