Holford has had varied engagements with Cochrane Reviews, so we were interested to see the Holford Diet site – which promotes a low glycaemic load (LGL) diet plus supplements – celebrating one Review’s alleged finding that
a low GL diet is more effective than any other diet for weight loss and improving overall health…’Overweight or obese people lost more weight on a low Glycemic Load diet and had more improvements in lipid profiles than those receiving conventional diets.’
However, on looking at the Review itself we noted that it did not distinguish between LGL and low glycaemic index (LGI) diets. This was a review of
Randomised controlled trials comparing a low glycaemic index or load diet (LGI) with a higher glycaemic index or load diet or other diet (Cdiet) in overweight or obese people.
The review found some evidence that LGI and LGL diets can be especially beneficial, but did not aim to find whether an LGI or LGL diet was best. Given that this was a review of only six trials involving only 202 participants, this seems a sensible decision.
While it is nice to see a Holford site referring to such good quality sources, it is a shame that the Review could not have been reported more accurately.
Former Visiting Professor Patrick Holford is Head of Science and Education at Biocare. Despite the imprimatur of respectability about these confidence-inspiring titles, from time to time, there are disappointing errors in the content of Holford’s health advice and sales pitches for home tests and the evidence base for supplements. These errors are all the more dispiriting when one recalls that he was corrected about some of them more than two years ago. We don’t mean differences of opinion, we mean verifiable, checkable facts. When Holford persuades people to rely upon his opinion and lend credence to it because he undertakes to do the scientific research and interpret it for them then it seems inappropriate to claim that more people died, prematurely, from a specific cause than actually died, prematurely, from all causes.

What do they teach people at the Institute for Optimum Nutrition? When the founder of one’s alma mater is
Former Visiting Professor Patrick Holford this might, occasionally, give one pause as to exactly what is taught to the aspiring cohorts of students of nutritionism. Patrick Holford set up the Institute of Optimum Nutrition as a limited company, back when he was in such a state of despair as to the disparity between his own auto-didact expertise and that of people who had actually studied the topic for several decades and researched it in rigorous detail, that he felt that he had no option but to set up his own institute of learning to spread his own special take on nutritionism throughout the tranche of gullible like-minded, well-heeled seekers after knowledge.

HolfordWatch enjoyed Dr Ben Goldacre and Rami Tzabar’s 2-parter on The Rise of the Lifestyle Nutritionists on Radio 4 (see update for MP3 links). We thought that it was an interesting exploration of the scientific rhetoric that is intended to lend respectability to nutritionism, and its adherents.
Visiting Professor Patrick Holford was included as a notable example of a self-styled nutritionists who distorts research and reduces it to what was characterised as ‘a low and somewhat tabloid-y level of discourse’ with a hefty dose of promotion for supplements. We’ve just learned that it won the Norwich Union Healthcare Medical Journalism Award for National Radio, 2008. Continue reading
The Economist recently carried an article that reports a Food for the Brain conference and it linked to the charity, lending it some share of respectability. So, it is with bassoon notes of incompetence and inevitability that we learn of some Food for the Brain literature that has made its way into a café in Imperial College, London. Our sources tell us that, to date, no students have complained about the leaflet although there are 300 medical students, 200 biology students and many students of other science disciplines. So, either they thought it was an elaborate po-mo joke and they weren’t rising to it (if you’re at Imperial, there’s probably a good chance that you are already doing something right, vis-à-vis, using the brain well, studying efficiently) and dismissed it as yet another badly-written polemic by some interest group or other (actually…).

Visiting Professor Patrick Holford has his own dedicated chapter in Ben Goldacre‘s Bad Science: Chapter 9; pp 161-80. Both HolfordWatch and Holford Myths have commented that the CV which Holford submitted to the University of Teesside is riddled with a remarkable number of errors, several of which involve implausible timelines. Today, an outraged reader has submitted more evidence of confusion about Holford’s understanding of time as well as the evidence-base for chromium supplementation to “to stabilise blood sugar levels”.
