Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A single meal of a fast food breakfast of two sausage and egg breakfast sandwiches, and a hash brown, consisting of 4395 kJ, 63g fat, 75g carbohydrate and 43g protein. The meal is consumed for breakfast after an overnight fast (7pm to 7am) and followed by a two week wash-out period between study meals.

Lifestyle
Comparator / control treatment
A single meal of a 'healthy' breakfast of rolled oats prepared in skim milk, low fat cottage cheese with two fresh apricots, one slice whole wheat toast with reduced fat peanut butter, consisting of 2616 kJ, 17.4g fat, 75g carbohydrate and 43g protein. The meal is consumed for breakfast after an overnight fast (7pm to 7am) and followed by a two week wash-out period between study meals.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be recruited by public notices and advertisements placed in community newspapers. Telephone screening will firstly identify participants within the required age ranges and exclude those likely to be experiencing exclusion factors (family history of diabetes and heart disease, anti-inflammatory pharmaceutical use and BMI >30). Participants meeting this screening will be forwarded the Participant Information Sheet and Consent form. The participants will be invited to a face to face meeting with the researchers to ensure the Participant Information Sheet has been read and understood. If written consent is provided, a written general health questionnaire and baseline blood sample will be drawn to verify inclusion criteria by excluding diabetes and risk of heart disease. Participants meeting the inclusion requirement will be invited to undertake the study and a date provided for the first breakfast meal. Allocation will be concealed by use of sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e. computerised sequence generation)
Masking / blinding
Open (masking not used)

Summary
Brief summary
Meals high in fat cause a marked postprandial increase in low-grade inflammation. Although short-term, the resulting inflammatory response may have implications in long-term risk for chronic illness such as cardiovascular disease (CVD). It is unknown whether the postprandial inflammatory response to high-fat meals differs in older adults, and is still not clear how digestion and metabolism of fats is affected by age.

This study aims to analyse the digestive, physiological, inflammatory and immune responses to a single meal in young adults compared with older adults, of either a ‘fast-food’ breakfast (high in saturated fat and calories), or a ‘healthy’ breakfast (low in saturated fat, following dietary guidelines set out by The Australian Guide to Healthy Eating).
