Research student
Career Summary
Biography
Accredited Practising Dietitian (APD) and full-time PhD candidate (Nutrition and Dietetics) at the University of Newcastle.
The focus of Jacklyn's PhD is to investigate the role of dietary nitrate and nitrite on cardiovascular disease risk factors and outcomes. More specifically, Jacklyn aims to understand whether a higher habitual intake of dietary nitrate and nitrite leads to improved cardiovascular disease related outcomes in humans.
This will be primarily achieved through epidemiological investigation of two Australian cohorts, and one cohort from the United States of America. At the end of 2016, Jacklyn spent 12 weeks at the Harvard School of Public Health working on the Nurses' Health Study data, a project which was carried out in collaboration with pre-eminent Nutritional Epidemiologists, Professor Walter Willett and Professor Eric Rimm.
Jacklyn is keen to develop her skills, experiences and expertise within the field of Nutrition and Medical reserach.
In particular, Jacklyn is extremely interested in understanding how dietary and lifestyle factors can improve the health of the community, and has a key interest in the practical applications of Public Health Nutrition. Jacklyn is also passionate about the effective and responsible communication of Nutrition Research to the public. So far, Jacklyn has spoken as a representative for the Dietitians Association of Australia (DAA) and was awarded 2nd place, and People's Choice in the 2017 University of Newcastle's 3 Minute Thesis competition.

[more] Objective: To explore if better diet quality scores as a measure of adherence to the Australian Dietary Guidelines (ADG) and the Mediterranean diet (MedDiet) are associated with a lower incidence of hypertension and non-fatal CVD.Design: Prospective analysis of the 1946-1951 cohort of the Australian Longitudinal Study on Women's Health (ALSWH). The Australian Recommended Foods Score (ARFS) was calculated as an indicator of adherence to the ADG; the Mediterranean Diet Score (MDS) measured adherence to the MedDiet. Outcomes included hypertension and non-fatal CVD. Generalised estimating equations estimated OR and 95 % CI across quartiles of diet quality scores.Setting: Australia, 2001-2016.Participants: 1946-1951 cohort of the ALSWH (n 5324), without CVD, hypertension and diabetes at baseline (2001), with complete FFQ data.Results: There were 1342 new cases of hypertension and 629 new cases of non-fatal CVD over 15 years of follow-up. Multivariate analysis indicated that women reporting better adherence to the ARFS (=38/74) had 15 % (95 % CI 1, 28 %; P = 0·05) lower odds of hypertension and 46 % (95 % CI 6, 66 %; P = 0·1) lower odds of non-fatal CVD. Women reporting better adherence to the MDS (=8/17) had 27 % (95 % CI 15, 47 %; P = 0·0006) lower odds of hypertension and 30 % (95 % CI 2, 50 %; P = 0·03) lower odds of non-fatal CVD.Conclusions: Better adherence to diet quality scores is associated with lower risk of hypertension and non-fatal CVD. These results support the need for updated evidenced based on the ADG as well as public health nutrition policies in Australia.

Although governments and researchers alike recognise the burden that obesity incurs for increased healthcare spending, there is insufficient evidence for the role of diet quality on healthcare costs. Methods: Diet quality was assessed by the Australian Recommended Food Score (ARFS) for 6328 women aged 50¿55 years from the Australian Longitudinal Study on Women's Health. The ARFS was ranked by quintile, and 10-year cumulative data on healthcare costs from Medicare (Australia's Universal healthcare cover) were reported by body mass index category, using generalised linear modelling. Results: Healthy weight women with the highest diet quality were found to make significantly fewer Medicare claims (P = 0.012) compared to those with the lowest diet quality. In healthy weight and overweight women, the number of healthcare claims and charges was inversely associated with consuming a greater variety of vegetables. For every 1 point increase in the ARFS vegetable component score, healthy weight women made 1.9 fewer healthcare claims and were charged $139 less, whereas overweight women made 2.3 fewer claims and were charged $176 less for healthcare over 10 years. Conclusions: The results of the present study support the need to prioritise an improved diet quality with the aim of reducing healthcare claims and overall costs in a population-based sample of Australian females. As the burden of overweight and obesity on the healthcare system increases, strategies to improve diet quality may be of particular importance; however, more research is required to further establish this relationship.

This is of concern as ID has been shown to affect immunity, thermoregulation, work performance and cognition. Animal flesh foods provide the richest and most bioavailable source of dietary (haem) iron, however, it is unclear whether low animal flesh diets contribute to ID. This systematic review aimed to investigate whether a higher consumption of animal flesh foods is associated with better iron status in adults. CINAHL, Cochrane, EMBASE and MEDLINE were searched for published studies that included adults (¥18 years) from developed countries and measured flesh intakes in relation to iron status indices. Eight experimental and 41 observational studies met the inclusion criteria. Generally, studies varied in population and study designs and results were conflicting. Of the seven high quality studies, five showed a positive association between animal flesh intake (85¿300 g/day) and iron status. However, the optimum quantity or frequency of flesh intake required to maintain or achieve a healthy iron status remains unclear. Results show a promising relationship between animal flesh intake and iron status, however, additional longitudinal and experimental studies are required to confirm this relationship and determine optimal intakes to reduce ID development.
