A meat free year (and the growing evidence base)

February 9, 2019 No Comments

I blogged last year about my steady drift towards a fully plant-based diet, and discussed some of of the key considerations and questions of doing so. I’m happy to report that this drift has continued, and I managed to avoid eating meat for the whole of 2018. Well OK, that is not entirely true, as I had one mishap on the flight back from my own stag do in Porto, when I ate a bread roll with chicken puree which I thought was hummous. Hard to believe that my abstinence was broken, not for a juicy burger or Sunday roast, […]

Marathon blues

April 17, 2018 No Comments

I’ve got the marathon blues. Last year’s final few weeks of long training runs were so punishing that I’d made up my mind long before race day that I’d be taking the following year off. More importantly, I then stubbornly stuck to that decision despite the euphoria that followed. So, I won’t be running London on Sunday, and it will mark my first year in six without a marathon. With my usual home town half in Bath also cancelled this year due to that (first) ridiculous week of spring snow, the only organised runs I’ve been doing are Park Runs. […]

Veganism and the plant based revolution (part II)

April 17, 2018 No Comments

A week later than planned (as ever), here is the second part to my blog on plant based diets, this time looking at the final four FAQs that come my way as a Registered Dietitian. Some of it is a bit lengthy (and I promise future posts won’t always be), but it’s a huge topic and one that could probably have been split across about five blogs rather than two. I could easily have expanded on all of these answers, but it’s a start at least! Q2. What about protein? Protein remains all the rage, and people often worry that a plant […]

Veganism and the plant based revolution (part I)

March 28, 2018 No Comments

Q: How do you know if someone’s a vegan? A: Don’t worry – they’ll tell you There’s something about vegans that really gets under other people’s skin. They find themselves the butt of jokes for being smug / puny / dull / joyless / awkward / sanctimonious etc etc…and to be perfectly honest, I’ve had times when I’ve thought the same. I used to be more than a little sceptical of veganism (and vegans), thinking it an unnecessarily restrictive lifestyle, and the preserve of preachy individuals who wear shoes made from hemp. No-one likes being told what to eat (or […]

Introduction to Intensive Care

February 8, 2018 No Comments

My clinical career has seen some significant changes recently, so I thought I’d write a quick post to briefly update and reflect on a busy few months in the day job (and inevitably the language will be slightly more clinical than usual – apologies!) For the second half of 2017, I took on the role of Senior Specialist Dietitian in Lower Gastrointestinal Surgery and Gastroenterology at my previous trust, Imperial. Given the nature of the surgery and diseases in this population (e.g. bowel cancer, crohn’s, pancreatitis), patients are often unable to digest food normally, with their intestinal tracts either inaccessible […]

London Marathon 2017

April 24, 2017 No Comments

Reflecting on my time in South America, I mentioned that the unhealthy diet and scorching heat would probably end any hopes of beating my marathon PB this year. Despite my best efforts of catching up on return to the UK, this proved to be the case, although I was still chuffed to come in at 2h 53m, just a couple of minutes over last year’s time. Most people are familiar with the phrase ‘carb-loading’, and I always take this pursuit almost as seriously as the training itself, particularly in the days leading up to the race. Food basically becomes just fuel during […]

Largentina

March 19, 2017 No Comments

I’ve been a bit quieter on her recently, and although this can be partly attributed to the chaotic struggle for spare time that we call ‘life’ in London, more recently it is due to me taking a break from my day job as a dietitian for a few months and moving to Argentina. Latin America is my favourite part of the world, so when two friends asked me to join them on their trip, it was an easy decision (well, for me at least…maybe not for my employer!) We kept our plans for the trip deliberately vague, but the absurd […]

6 Problems Facing Diet Research

February 24, 2015 No Comments

Last week, I discussed the ongoing saturated fat debate, and hinted that diet research is often flawed… which can be why dietary science or evidence appears inconclusive. Here are six reasons to help explain why that can be the case: 1. Long follow-up times The effects of dietary approaches are not going to be seen overnight. Instead, impacts on health might take years, or more likely, decades (which is why it is the habits of a lifetime that matter, not those of a month after Christmas). This means that studies have to be hugely ambitious from the outset, taking into […]

Heart Month… and the saturated fat debate

February 17, 2015 No Comments

You may or may not be aware that we’re in the middle of Heart Month. I’m not sure if it’s got anything to do with Valentine’s and the preponderance of heart shaped tat filling shop windows, but February is the chosen month for raising awareness of this most vital of organs. A quick google search suggests USA and Canada do it in February too. Who knows – maybe we copied them. You don’t need me to tell you how important the heart is. Equally, I can’t imagine you need me to tell you that heart disease is, alongside cancer, the biggest […]

Minerals & mental health

February 3, 2015 No Comments

Following on from last week’s blog, where I discussed the major links between vitamins and brain function, let’s now conclude this topic by looking at the potential role of minerals, trace elements and other dietary components in mental health. Like vitamins, strong associations between mineral deficiencies and mental illness have been seen, although it should be said that in some cases, the mechanisms remain unclear. Chromium is one such example, with deficiencies particularly prevalent in patients with depression. Iodine is absolutely crucial for mental health and development. It is involved in energy metabolism in brain cells, and in development a severe […]
