Eggs, cancer, and motivated reasoning

The following headline in the The Daily Express caught my attention this week:

“Ovarian cancer – could EGGS be the cause of disease? Vegan charity research REVEALED”

Express.co.uk 14th March 2017

The article goes on to explain that a Bristol based charity called Viva! Health has urged consumers not to eat eggs, claiming that one egg a week increases cancer risk by up to 70%. According to their own website, Viva! Health is a science-based health and nutrition charity, and being “science-based” you would expect them to have sufficient evidence to make a claim as eye-catching as the one above. So is this the case?food-eggs

Does Nutella cause cancer?

nutellaOn a recent cycling trip in Canada, I ate an obscene amount of Nutella. It works as a great lunch, and dipping fresh bread in it is a delicious snack. When you are exercising all day every day, a tasty, spreadable, dippable energy source like this is extremely useful. Don’t get me wrong, it is a very unhealthy food, but despite this, I’m a fan.

Which is why I was surprised this week to see Ferrero (the makers of Nutella) defending their product against claims that it causes cancer. A quick internet search revealed the problem. As the Tech Times put it: “Nutella Can Cause Cancer, Study Warns”. The Huffington Post ran with: “Stores Are Pulling Nutella After Report Links It To Cancer”, while the Daily Mail asked “Could Nutella give you CANCER?”. So what is this all about, and should you stop eating Nutella? Continue reading

Alternative medicine as a placebo

I recently wrote a post about the decision by NICE to no longer recommend acupuncture for lower back pain. This decision was made because, like most alternative medicine, acupuncture hasn’t been shown to work any better than a placebo. However, plenty of people use and get benefit from such treatments. This raises an interesting question: is there a place for complementary and alternative medicine (as a placebo) in the clinic? Continue reading

Acupuncture no longer recommended for back pain

NICE (the organisation that provides guidance to doctors in the UK) recently updated their recommendations regarding lower back pain. In the updated guidance, they say that exercise, in all its forms (for example, stretching, strengthening, aerobic or yoga), is the most important step in managing back pain.

Previously, NICE also recommended acupuncture or massage, but this has now been altered. Massage can still be used alongside exercise, but the guidelines no longer recommend acupuncture, as “evidence shows it is not better than sham treatment”. Continue reading

Doping: Not worth the risk

ciclista_y_doping_226215Elite tennis player Maria Sharapova’s fall out over banned substance Meldonium has been all over the news the past couple of weeks. This drug was added to the list of prohibited substances only in January 2016 and as of the 15th of March 2016 it has already been reported in 100 athletes.

Meldonium is used in Eastern Europe to treat angina and heart stroke: severe cardiovascular problems related to lack of blood supply to vital muscles. It is unlikely that any of those elite athletes actually suffered from those diseases. Most of them were taking the drug with the aim of enhancing
their performance-  and they were getting away with it.

Ironically, the performance enhancing properties of this drug- and of many of the other doping substances- have never been conclusively proved. Continue reading

Can Wi-Fi make you sick?

A French court recently awarded a disability grant to a woman claiming to suffer from electromagnetic hypersensitivity. Sufferers define this as an illness caused by the radiation given out by everyday objects (Wi-Fi routers, mobile phones and power lines, for example), resulting in a wide range of non-specific symptoms, including headaches, fatigue and irregular heartbeats. There have been several lawsuits in the US from people claiming that their health has been affected by Wi-Fi (unsuccessful so far), and just this week in Massachusetts parents have sued a school, claiming that the Wi-Fi there made their son ill.
