Statin found to largely negate the fitness benefits of exercise

A major motivator for many to take exercise is the desire to ‘get fit and healthy’. Regular exercise induces changes that can increase things like strength and endurance. One particular adaptation to exercise concerns increased numbers of tiny structures called mitochondria (my-toe-con-dree-ah) in the cells. Most of our energy needs are met by the metabolism [...]

Two reviews reveal the lack of evidence for HDL-boosting agents

Cholesterol is transported in the bloodstream packaged with protein in the form of ‘lipoproteins’. There’s two main forms of lipoprotein in the blood: so-called ‘low density lipoprotein’-cholesterol (LDL) and ‘high density lipoprotein’-cholesterol (HDL). Traditionally, LDL has been said to be chiefly responsible for the depositing of cholesterol on the inside of the arteries and the [...]

How does sunlight cause melanomas on the soles of the feet?

This article in the Daily Mail caught my eye today. It concerns, as often seems to be the case at this time of year, the perils of sun exposure. It includes the comments of a consultant dermatologist who tells us that she wears factor 30 or higher sunscreen on her face throughout the year, “even [...]

Forbidding foods may cause us to obsess about them, and what to do about it

I came across this story today in the Daily Mail, concerning what can happen when we deny ourselves something. Apparently, according to this research, resisting something we desire can make us think about it more. Interestingly, if the same thing is denied to people more generally, it tends not to have this effect [1]. So, [...]

Is publishing ‘league tables’ of surgeons’ performance good for patients?

I read today that from later this summer, survival rates for the patients of surgeons in the UK will be made available to patients. The idea is, then, that patients can choose who treats them. According to Health Secretary Jeremy Hunt: The Health Secretary said: “Transparency and participation must be the operating principles of the [...]

No evidence for the ‘blood type diet’, but does it work?

I had an email from someone asking me about the blood type diet. The ‘Eat Right for your Type’ diet was hugely popular in the US and also here in the UK from the mid 90s. The diet is based on the ‘ABO’ system of typing blood. This system gives us four blood groups depending [...]

Could this simple strategy stop snoring and sleep apnoea?

Have you ever started out looking for something on-line, got diverted, and then ended up at a completely unplanned and unrelated destination on the internet? I have to admit, for me, it happens a lot. It happened yesterday, in fact, when I was reading a piece about blood pressure treatment, and found myself clicking on [...]

Statins deplete the body of a nutrient that is vital for heart function

Coenzyme Q10 is a chemical which plays a key role in the production of energy in the body’s cells. Specifically, this substance participates in the processes within tiny powerhouses in cells known as ‘mitochondria’ (my-toe-con-dree-ah). Coenzyme Q10 is essential for the production of ATP (adenosine triphosphate), a basic currency for energy in the body. All [...]

Are kids really being reckless for seeking the sun and shunning sunscreen?

I spied this ‘editorial’ in the Daily Mail this week (we’ll come to why editorial is in quotes in a moment). It’s about a poll that shows, apparently, a significant number of young children are refusing to wear sunscreen. One in three, apparently, will seek to get out in the sun at every available opportunity. [...]

Avoiding evening eating found to promote weight loss

When I was medical school, I noticed one of my friends had lost a bit of weight (intentionally). Even though I was not really interested in things like weight control and diet in those days, my curiosity got the better of me and I asked him how he did it. Had he cut back on [...]
