Milk and Parkinson’s

As the population has been getting older, there has been increased attention paid to neurodegenerative diseases, such as Alzheimer’s and Parkinson’s. These are diseases that cause a progressive loss of mental function (dementia), or problems with movement, such as tremors. The causes of these diseases are still relatively unknown, so there is a lot of public interest in studies that look at this. This week a paper was published that suggests there may be a link between high consumption of low fat dairy (particularly milk), and Parkinson’s. This was picked up by numerous media outlets, with predictable headlines. Continue reading

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

Using stem cells to treat cancer

There are many scam artists around nowadays proclaiming the benefits of their particular unproven stem cell therapy, for anything from curing cancer to making paralysed people walk again. It’s not surprising really; stem cells are a pool of cells in every organ that are almost eternally youthful and can regenerate themselves and all other cells in the organ. They sound almost magical. However, last year the FDA (the US Food and Drug Administration) had to move to crack down on these clinics, citing the of lack of evidence that any of them work and a number of serious complications reported following treatment. Complications including patients in Florida dying, a woman developing bone fragments in eyelids following a stem cell facelift, and another developing nasal tissue in her spine after a doctor promised to cure her paralysis with stem cells.

It is a field ripe for abuse partly because it is one with so much potential. Stem cells do have fascinating possible applications, and there is a lot of research going in to them at the moment. Unfortunately, most exposure people have with them is in science fiction or alternative medicine. Which is why it was very interesting to see a study published last week that underlined how much real potential this field of research has. The study used mice instead of humans, so is still at an early stage, but is very promising nonetheless. Continue reading

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

Royal College of Physicians recommends e-cigarettes for smokers

A few months ago I wrote here about the rise of e-cigarettes. In that post I pointed out that e-cigarettes are far less harmful than tobacco, and should be marketed as a safer alternative to smoking. There has been an interesting update on this topic today, with the Royal College of Physicians (RCP) recommending that all smokers be offered and encouraged to use e-cigarettes. 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
