Why is the research being done?

Dietary patterns, rich in plant-derived foods have gained popularity in Australia and worldwide due to societal trends, ethical and environmental sustainability concerns and perceived healthiness. However, the nature of plant-based dietary patterns, currently being followed by Australians is unclear and moreover, the nutritional adequacy of these diets is questionable. The overall health status of individuals across different dietary patterns will be compared along with the risk of developing cardiovascular disease, the leading cause of death worldwide. Collection of information and measurements from you will enable us to examine the relationship between the health status of Australian adults and the types of plant-based dietary patterns followed.

Who can participate?
You are eligible to participate in this study if you are:
• Male or female aged between 35 and 70 years
• Do not have existing cardiovascular disease and/or are being treated for cardiovascular diseases.

You are NOT eligible to participate if you are of the following:
Cardiovascular disease diagnosed and/or are being treated for cardiovascular disease i.e. myocardial infarction, coronary insufficiency, angina, ischaemic stroke, transient ischaemic attack, haemorrhagic stroke, peripheral artery disease and heart failure or have a pacemaker implanted
• Pregnant or breastfeeding
• Commenced a dietary intervention in the past 6 months
• Made significant changes to your normal dietary patterns, food choices, lifestyle and/or physical activity levels in the past 6 months
• Currently participating in (or in the last 30 days) another research intervention trial involving making changes to your diet and/or physical activity levels.

*If you have had a previous radiological or nuclear medicine investigation in the past 7 days, you must notify the study investigators so that your clinic appointment can be scheduled for at least 14 days apart.

What will I be asked to do?
If you agree to participate you must sign and return by mail, email or in person your consent form - this is mandatory for study participation and required before attending any appointments related to this study. You will then be asked to visit the Nutraceuticals Research Program Clinical Trial Facility at the University of Newcastle on ONE occasion for a clinic appointment that will take approximately 2-hours. During this clinical appointment, various measurements and information will be collected from you, such as:
• Hardcopy of your signed consent form
• Complete 3 questionnaires: medical and demographic questionnaire, physical activity questionnaire and online Australian Eating Survey food frequency questionnaire
• Have a diet history collected
• Blood sample
• Waist circumference and blood pressure

You will be provided with a light breakfast at the end of your clinic appointment. You will be provided with a parking permit upon arrival to our facility, which is valid for your appointment duration in the specified bays as indicated on the ‘Directions & Maps’ instructions provided to you. Blood will be collected by a phlebotomist either at the Nutraceuticals Research Program or at a local pathology service (Pathology North located at Wallsend or Callaghan Campus) accompanied by a researcher using the School of Biomedical Sciences and Pharmacy service car.

You will also be asked to visit the Newcastle Bone Density Centre on ONE occasion for a full body x-ray scan appointment that will take approximately 15 minutes. During this appointment body composition (including height & weight) and bone mineral content will be measured using dual-energy x-ray absorptiometry (DXA). You will be asked to wear light clothing without metal or wear a gown that will be supplied to you by the Newcastle Bone Density Centre. You will then be asked to lie on a scanner bed while a scanning arm passes over the body. The scan itself takes approximately 6 minutes.
