Dietary Docosahexaenoic Acid And Arachidonic Acid In Early Life: What Is The Best Evidence For Policymakers?, Stewart Forsyth, Philip C. Calder, Francis Zotor, Paul Amuna, Barbara J. Meyer, Bruce Holub

Faculty of Science, Medicine and Health - Papers: part A

Background: A wealth of information on the functional roles of docosahexaenoic acid (DHA) and arachidonic acid (ARA) from cellular, animal, and human studies is available. Yet, there remains a lack of cohesion in policymaking for recommended dietary intakes of DHA and ARA in early life. This is predominantly driven by inconsistent findings from a relatively small number of randomised clinical trials (RCTs), which vary in design, methodology, and outcome measures, all of which were conducted in high-income countries. It is proposed that this selective evidence base may not fully represent the biological importance of DHA and ARA during early and …

Dietary Iodine Intake Of The Australian Population After Introduction Of A Mandatory Iodine Fortification Programme, Karen E. Charlton, Yasmine Probst, Gabriella Kiene

Illawarra Health and Medical Research Institute

To address mild iodine deficiency in Australia, a mandatory fortification program of iodised salt in bread was implemented in 2009. This study aimed to determine factors associated with achieving an adequate dietary iodine intake in the Australian population post-fortification, and to assess whether bread consumption patterns affect iodine intake in high-risk groups. Using nationally representative data of repeated 24-h dietary recalls from the 2011-2012 Australian National Nutrition and Physical Activity Survey, dietary iodine intakes and food group contributions were compared by age, socioeconomic status (SES), and geographical remoteness (N = 7735). The association between fortified bread intake and adequacy …

Background: Modern diets, characterised by excess consumption of processed foods, are accompanied by an epidemic of chronic diseases. Cardiovascular disease and depression carry a large burden of disease and often occur together. Poor dietary patterns have been identified as an independent risk factor for depression while healthy diets with minimally processed food are protective. Traditional Mediterranean diets have been shown to reduce risk of cardiovascular disease; however there is a need for clinical trials in people with depression. This paper reports the study protocol of a Mediterranean-style diet intervention conducted in adults with self-reported depression. Methods/design: HELFIMED is a parallel …

Faculty of Science, Medicine and Health - Papers: part A

Increased salt intake leads to an increase in blood pressure and decreased sodium intake relative to the usual or increased intake results in lowered blood pressure in adults, with or without hypertension. Blood pressure is a strong proxy indicator for the risk of cardiovascular disease, coronary heart disease and strokes. Hypertension is estimated to have caused 9% of all deaths in South Africa in 2000. In 2008, 42% of men and 34% of women aged 35-44 years, and 60% of men and 50% of women aged 45-54 years, were hypertensive. More than 70% of both men and women older than …

Illawarra Health and Medical Research Institute

High-fat (HF) diet and obesity are risk factors for a number of mental health problems including depression, cognitive dysfunction, dementia, and neurodegenerative diseases. Histamine H1 receptors (H1Rs) are involved in many of these conditions. This study examined H1R receptor binding density in the brain of male rats fed a high-saturated fat (HF) diet, as well as the effect of docosahexaenoic acid (DHA), galacto-oligosaccharide (GOS) and resistant starch (RS) supplementation of HF diet. Alterations of H1R expression in the post-mortem rat brain were detected by [ 3H]-pyrilamine binding autoradiography. We found that HF diet significantly decreased H1R binding densities in the …

Dietary Fish Oil Preserves Cardiac Function In The Hypertrophied Rat Heart, Peter L. Mclennan, Mahainda Y. Abeywardena, Julie A. Dallimore, Daniel Raederstorff

Graduate School of Medicine - Papers (Archive)

Regular fish or fish oil intake is associated with a low incidence of heart failure clinically, and fish oil-induced reduction in cardiac remodelling seen in hypertrophy models may contribute. We investigated whether improved cardiac energy efficiency in non-hypertrophied hearts translates into attenuation of cardiac dysfunction in hypertrophied hearts. Male Wistar rats (n 33) at 8 weeks of age were sham- operated or subjected to abdominal aortic stenosis to produce pressure-overload cardiac hypertrophy. Starting 3 weeks post-operatively to follow initiation of hypertrophy, rats were fed a diet containing 10% olive oil (control) or 5% fish oil (ROPUFA30 (17% EPA, 10% DHA)) …

The aim of this study was to compare the effect of specific or general fish consumption recommendations on fish intake behavior over the duration of a 12-month clinical trial. Participants were randomized into a control group (general die-tary advice), and two intervention groups (received dietetic advice to consume 180 g fish/wk), with one intervention group receiving LC omega-3 PUFA supplements. Dietary data was available for n = 117 at baseline, n = 85 at 3 months and n = 63 at 12 months. Total, …


Dietary Docosahexaenoic Acid (22:6) Incorporates Into Cardiolipin At The Expense Of Linoleic Acid (18:2): Analysis And Potential Implications, Colin Cortie, Paul L. Else Jan 2012

Dietary Docosahexaenoic Acid (22:6) Incorporates Into Cardiolipin At The Expense Of Linoleic Acid (18:2): Analysis And Potential Implications, Colin Cortie, Paul L. Else

Faculty of Science, Medicine and Health - Papers: part A

Cardiolipin is a signature phospholipid of major functional significance in mitochondria. In heart mitochondria the fatty acid composition of cardiolipin is commonly viewed as highly regulated due to its high levels of linoleic acid (18:2n − 6) and the dominant presence of a 4×18:2 molecular species. However, analysis of data from a comprehensive compilation of studies reporting changes in fatty acid composition of cardiolipin in heart and liver mitochondria in response to dietary fat shows that, in heart the accrual of 18:2 into cardiolipin conforms strongly to its dietary availability at up to 20% of total dietary fatty acid and …

Faculty of Health and Behavioural Sciences - Papers (Archive)

High-fat diet (HFD) induces obesity. This study examined the effects of Shiitake mushroom on the prevention of alterations of plasma lipid profiles, fat deposition, energy efficiency, and body fat index induced by HFD. Rats were given a low, medium, and high (7, 20, 60 g/kg = LD-M, MD-M, HD-M) Shiitake mushroom powder in their high-fat (50% in kcal) diets for 6 weeks. The results showed that the rats on the HD-M diet had the lowest body weight gain compared to MD-M and LD-M groups (P < 0.05). The total fat deposition was significantly lower (-35%, P < 0.05) in rats fed an HD-M diet than that of HFD group. Interestingly, plasma triacylglycerol (TAG) level was significantly lower (-55%, P < 0.05) in rats on HD-M than HFD. This study also revealed the existence of negative correlations between the amount of Shiitake mushroom supplementation and body weight gain, plasma TAG, and total fat masses.

Increased Intake Of Dietary Polyunsaturated Fat Does Not Promote Whole Body Or Preferential Abdominal Fat Mass Loss In Overweight Adults, Sze-Yen Tan, Marijka Batterham, Linda Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: There is evidence that increasing the proportion of polyunsaturated fatty acids (PUFA) in a diet can enhance the rate of fat oxidation acutely. Higher PUFA in a diet has also been associated with greater abdominal fat loss in longer term studies. This study aimed to investigate if higher PUFA intake would result in greater fat mass loss over a 12-week period, mainly from the abdominal region.

Methods: Data at the 12-week time point from two weight loss studies, both comparing high PUFA versus low PUFA diets was, accessed for 141 overweight subjects from the same area. Specifically, data on …
