Academic Profiles

Research Interests

Since returning from a lengthy career gap (20-years out of research), my work, has focussed on trace elements of importance to health, most notably selenium but also iron and more latterly, iodine (see selected publications below). I am interested in:

  • the effect of low selenium status on the risk of hypertensive conditions of pregnancy, most notably pre-eclampsia;
  • the effect of selenium and iodine status on auto-immune thyroid disease and on thyroid function in pregnancy (an RCT on the effect of selenium and iodine status on auto-immune thyroid disease in a low-selenium area of China is planned);
  • the effect of iodine status in pregnancy on cognitive, auditory and psychomotor development in the child and on pregnancy outcome.

Research Collaborations

I currently collaborate with academics at some 20 other universities and research institutes throughout the world.

Teaching

  •  BSc degree programmes in Nutrition, Nutrition & Dietetics, Nutrition & Food Science: lecture topics include selenium, iodine and manganese.
  • MSc Human Nutrition
    I lecture on selenium and human health.
  • MSc Nutritional Medicine
    My major contribution to teaching in the University has been the creation of the very successful Nutritional Medicine post-graduate programme, the first (and still unique) university-level, evidence-based course in the UK designed for the in-service training of doctors and other health professionals in the use of nutritional methods of disease prophylaxis and management.

The Programme, of which I am Director, has now been running for 11 years during which time it has been extremely successful, achieving a high profile and excellent reputation. We draw a considerable number of students from Europe and from countries as far away as China, Canada and South Africa. Currently there are 155 registered part-time students, the majority of whom are practising clinicians, including consultants, and a substantial number of gastroenterologists.

  • I organise a number of MSc Nutritional Medicine modules and lecture on topics including selenium, iodine, osteo- and rheumatoid arthritis; diet and prostate cancer; pre-eclampsia.
  • You can read the menu for "The Antioxidant and Phytoprotectant Dinner" which forms part of the learning experience on the “Antioxidants and Phytoprotectants” module.
  • You can find information on Nutritional Medicine at here

    Abstract

    Iodine is required for adequate thyroid hormone production, which is essential for brain development, particularly in the first trimester of pregnancy. Milk is the principal source of iodine in UK diets, and while small studies in Europe have shown organic milk to have a lower iodine concentration than conventional milk, no such study has been conducted in Britain. In view of the increasing popularity of organic milk in the UK, we aimed to compare the iodine concentration of retail organic and conventional milk and to evaluate regional influences in iodine levels. Samples of organic milk (n 92) and conventional milk (n 80), purchased from retail outlets in sixteen areas of the UK (southern England, Wales and Northern Ireland), were analysed for iodine using inductively coupled plasma MS. The region of origin of the milk was determined from information on the label. Organic milk was 42·1 % lower in iodine content than conventional milk (median iodine concentration 144·5 v. 249·5 ng/g; P < 0·001). There was no difference in the iodine concentration of either conventional or organic milk by area of purchase. However, a difference was seen in iodine concentration of organic milk by region of origin (P < 0·001). The lower iodine concentration of organic milk has public-health implications, particularly in view of emerging evidence of iodine deficiency in UK population sub-groups, including pregnant women. Individuals who choose organic milk should be aware that their iodine intake may be compromised and should ensure adequate iodine intake from alternative sources.

    Abstract

    Use of selenium enriched foods, supplements and fertilizers has increased markedly in recent years in the US and other Western countries because of the perception that the anti-oxidant properties of selenium could potentially reduce the risk of cancer and other chronic diseases. However, concern has been raised recently about possible adverse cardiometabolic effects of high selenium exposure, including an increased risk of diabetes and hyperlipidemia with high selenium intake. Hence, from a public health perspective, the relationship between selenium status and cardiometabolic health should be clarified in order to help guide consumers in their choices of nutritional supplements and enriched food products. Additional experimental evidence is needed to provide new insights into the role of selenium and of specific selenoproteins in human biology, especially to clarify the underlying mechanisms linking selenium to chronic disease endpoints. Further epidemiological studies and randomized clinical trials across populations with different selenium status should be conducted to determine the causal effect of selenium on cardiovascular disease and risk factors. Nevertheless, at the present time the widespread use of selenium supplements or other strategies that artificially increase selenium status above the level required for optimal selenoprotein activity is not justified and should not be encouraged

    Abstract

    Knowledge of the plasma selenium levels associated with optimised concentration or activity of specific selenoproteins can provide considerable insights from epidemiological data on the possible involvement of those selenoproteins in health, most notably with respect to cancer. For cohort studies, if selenoproteins such as glutathione peroxidase and selenoprotein P are relevant to cancer, one might only expect to see an effect on risk when the concentrations in the cohort range from below, to above, the level needed to optimise the activity or concentration of these enzymes. Similarly, trials would only show a beneficial effect of supplementation if selenium status were raised from below, to above, the optimal concentration for the selenoproteins likely to be implicated in cancer risk, as occurred in the NPC trial but not in SELECT. The most powerful evidence for the involvement of selenoproteins in human health comes from epidemiological studies that have related single nucleotide polymorphisms in selenoproteins to disease risk. The totality of the evidence currently implicates GPx1, GPx4, SEPS1, Sep15, SEPP1 and TXNRD1 in conditions such as cardiovascular disease, pre-eclampsia and cancer. Future studies therefore need to determine not only selenium status, but genotype, both in selenoproteins and related pathways, when investigating the relationship of selenium with disease risk.

    Abstract

    There is a growing appreciation that it is not just the total intake of dietary selenium (Se) that is important to health but that the species of Se ingested may also be important. This review attempts to catalogue what is known about Se species in food sources and supplements and the health effects in which they are implicated. The biosynthetic pathways involved in Se assimilation by plants and the way in which Se species are metabolized in animals are presented in order to give an insight into the species likely to be present in plant and animal foods. Known data on the species of Se in the food chain and in food supplements are tabulated along with their concentrations and the analytical methodology used. The latter is important since identification that is only based on retention time matching with authentic standards must be considered as tentative: for evidence of structural confirmation, fragmentation of the molecular ion in addition to MS data is required. Bioavailability, as normally defined, is higher for organic Se species. Health effects, both beneficial and toxic, thought to be associated with specific Se species are described. Potent antitumour effects have been attributed to the low-molecular-weight species, Se-methyl-selenocysteine and its γ-glutamyl-derivative, found in a number of edible plants of the Allium and Brassica families. There remain considerable gaps in our knowledge of the forms of Se that naturally occur in foods. Without adequate knowledge of Se speciation, false conclusions may be drawn when assessing Se requirements for optimal health.

    Abstract

    Dietary advice and intervention clearly have a place in rheumatology and allow patients to have some control over their own disease. Although there is no evidence for efficacy of ‘fad’ diets, 30–40% of rheumatoid patients can benefit from excluding foods individually identified during the reintroduction phase of an elimination diet. A proportion of patients who follow a vegetarian or Mediterranean-type diet will experience benefit. Patients who are either overweight or obese should participate in weight-loss programmes. Those with osteoarthritis need to concentrate on reducing fat mass while maintaining muscle mass. Arthritic patients, other than those with gout, should increase their intake of oily fish and additionally supplement with fish oil for up to 3 months to see whether they experience benefit. All arthritic patients, particularly those with inflammatory disease, should be advised to ensure a good dietary intake of antioxidants, copper and zinc. Supplementation with selenium and vitamin D may be advisable.

    Abstract

    Selenium (Se) is an unusual trace element in having its own codon in mRNA that specifies its insertion into selenoproteins as selenocysteine (Sec), by means of a mechanism requiring a large Sec-insertion complex. This exacting insertion machinery for selenoprotein production has implications for our Se requirements for cancer prevention. If Se may protect against cancer, an adequate intake of Se is desirable. However, the level of intake in Europe and some parts of the world is not adequate for full expression of protective selenoproteins. The evidence for Se as a cancer preventive agent includes that from geographic, animal, prospective and intervention studies. Newly-published prospective studies on oesophageal, gastric-cardia and lung cancer have reinforced previous evidence which is particularly strong for prostate cancer. Interventions with Se have shown benefit in reducing the risk of cancer incidence and mortality in all cancers combined, and specifically in liver, prostate, colorectal and lung cancers. The effect seemed to be strongest in those with the lowest Se status. As the level of Se that appears to be required for optimal effect is higher than that previously understood to be required to maximise the activity of selenoenzymes, the question has been raised as to whether selenoproteins are involved in the anti-cancer process. However, recent evidence showing an association between Se, reduction of DNA damage and oxidative stress together with data showing an effect of selenoprotein genotype on cancer risk implies that selenoproteins are indeed implicated. The likelihood of simultaneous and consecutive effects at different cancer stages still allows an important role for anti-cancer Se metabolites such as methyl selenol formed from γ-glutamyl-selenomethyl-selenocysteine and selenomethylselenocysteine, components identified in certain plants and Se-yeast that have anti-cancer effects. There is some evidence that Se may affect not only cancer risk but also progression and metastasis. Current primary and secondary prevention trials of Se are underway in the USA including the SELECT prostate cancer trial, though a large European trial is still desirable given the likelihood of a stronger effect in populations of lower Se status.

    Abstract

    Selenium-enriched yeast (Se-yeast) is a common form of selenium used to supplement dietary intake of this important trace mineral. However, its availability within the EU is under threat owing to concerns expressed by the EC Scientific Committee on Food that Se-yeast supplements are poorly characterised and could potentially cause the build up of selenium in tissues to toxic levels. This review examines the validity of these concerns. Diagrams of the biosynthesis and metabolism of selenium compounds show which species can be expected to occur in Se-yeast preparations. Seyeast manufacture is described together with quality control measures applied by reputable manufacturers. The way in which speciation of Se-yeast is achieved is explained and results on amounts of selenium species in various commercial products are tabulated. In all cases described, selenomethionine is the largest single species, accounting for 54-74% of total selenium. Se-yeast is capable of increasing the activity of the selenoenzymes and its bioavailability has been found to be higher than that of inorganic selenium sources in all but one study. Intervention studies with Seyeast have shown the benefit of this form in cancer prevention, immune response and HIV infection. Of around one dozen supplementation studies, none has shown evidence of toxicity even up to an intake level of 800 μg/d selenium over a period of years. It is concluded that Se-yeast from reputable manufacturers is adequately characterised, of reproducible quality, and that there is no evidence of toxicity even at levels far above the EC Tolerable Upper Intake Level of 300 μg/d.

    Abstract

    The essential trace mineral, selenium, is of fundamental importance to human health. As a constituent of selenoproteins, selenium has structural and enzymic roles, in the latter context being best-known as an antioxidant and catalyst for the production of active thyroid hormone. Selenium is needed for the proper functioning of the immune system, and appears to be a key nutrient in counteracting the development of virulence and inhibiting HIV progression to AIDS. It is required for sperm motility and may reduce the risk of miscarriage. Deficiency has been linked to adverse mood states. Findings have been equivocal in linking selenium to cardiovascular disease risk although other conditions involving oxidative stress and inflammation have shown benefits of a higher selenium status. An elevated selenium intake may be associated with reduced cancer risk. Large clinical trials are now planned to confirm or refute this hypothesis. In the context of these health effects, low or diminishing selenium status in some parts of the world, notably in some European countries, is giving cause for concern.
