The connection between preventive health and health literacy

It was nice to read the article Michael Mosley’s Five Biggest Health Myths this weekend. On the same weekend I was in a store and overheard a conversation between customers about managing their common colds – they related their remedies of high doses of vitamin C and echinacea and were disappointed that it was still too cool to indulge in salt water. The first two methods are unproven in randomised trials and well, the latter, who knows.

Although I didn’t agree with all of Mosley’s advice (and he admitted some of it was based on early data) his underlying point is correct. We use our health knowledge (or health literacy) to inform our health choices.

Unfortunately many people really have poor health literacy – a lady I’ve treated for ovarian cancer for 18 months recently asked me where her pelvis is. The problem is aggravated by a proliferation of health myths. A lot of common information about diet and exercise is basically wrong or was ill-formed and made part of wide-spread public health initiatives.

One of the things we need to do to promote preventive medicine is actually provide accurate health information about diet and exercise rather than old-fashioned myths.

After that we need to know how to nudge people to follow the advice but that will be part of another blog post.
