Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Cognitively healthy subjects, aged 50 to 80 years old, will consume increasing doses of medium chain triglycerides for 8 weeks. Doses will increase from 0 to 35mL in 5mL increments every week. Participants will consume the interventional product in liquid form using a measuring cup, each dose will be consumed 3 times daily for 1 week. Participants will attend our facilities once a week for the duration of the study. At every appointment, participants will have their anthropometric measurements and blood pressure taken, will donate venous and capillary blood samples and will complete questionnaires assessing their medical history, physical activity, dietary habits, cognition and quality of life. At each appointment participants will return their used and unused containiers and these will be used to monitor adherence to the intervention. Blood samples will be assessed for cardiovascular disease and Alzheimer's disease biomarkers. In addition, postprandial assessments will be done at each appointment. Participants will also consume the interventional product at each appointment and have their ketone and glucose levels assessed over 2 hours (fasting, 1 hour and 2 hours after food consumption). The response for each outcome at each time point will be compared to determine a safe and tolerable dose to be used in a long-therm study.
Intervention code [1] 312442 0
Prevention
Comparator / control treatment
This study is a dose comparison for the determination of the ideal dose of medium-chain triglycerides to be consumed in a long-term study. Doses will be compared with each other and with the baseline week, when no interventional product had been consumed. Doses to be compared are 5mL, 10mL, 15mL, 20mL, 25mL, 30mL and 35mL,

Outcomes
Primary outcome [1] 307471 0
Side effects (number and severity)
Common side effects to MCT oils are loose bowel movements, increase in weight, stomach upset, bloating, diarrhoea-like symptoms, chest pains, nausea along with light headedness and dizziness. These side effects will be participant self-reported.
More serious side effects, which will be closely monitored, include increased liver enzymes, change in blood pressure, increased cholesterol levels, development of cardiovascular problems, allergic reactions. These side effects will be assessed at the participant weekly appointment and monitored using the blood tests and other assessment. Blood test assessments to determine safety include blood lipids (cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, triglycerides) and electrolytes and liver function tests (E'LFTs).
Timepoint [1] 307471 0
At baseline and after each dose (weekly for 8 weeks).
Primary outcome [2] 307495 0
Postprandial ketone levels.
For measuring this outcome participants will have their total blood ketone body levels measured fasting. They will then consume their morning dose of oil with their breakfast and 2 more blood samples will be collected (1 and 2 hours after breakfast). The postprandial levels determined for each dose will be compared.
Timepoint [2] 307495 0
At baseline and after each dose (weekly for 8 weeks).
Secondary outcome [1] 351998 0
Cognition
Cognition will be measured by a trained study staff personnel using a neuropsychological assessment battery developed by the study psychologist for this study.
Timepoint [1] 351998 0
At baseline and at the last appointment (in week 9, after 8 weeks of intervention).
Secondary outcome [2] 352069 0
Anthropometric measurements (weight, height, BMI, neck circumference, waist circumference and hip circumference). These are measured using a stadiometer, a scale and a measuring tape. This is a composite measure.
Timepoint [2] 352069 0
At baseline and after each dose (weekly for 8 weeks).
Secondary outcome [3] 352072 0
Plasma glucose
Measured by a pathology laboratory.
Timepoint [3] 352072 0
At baseline and after each dose (weekly for 8 weeks).
Secondary outcome [4] 370941 0
Alzheimer's disease biomarkers (plasma Aß, tau protein, brain derived necrosis factor). Biomarkers will be measured using Elisa kits. This is an exploratory outcome.
Timepoint [4] 370941 0
At baseline and after each dose (weekly for 8 weeks).
Secondary outcome [5] 373185 0
Compliance to the study protocol. This is a composite measure.
This will be measured using medical history along with changes to medications, physical activity and dietary habits.
Physical activity should not change during the study. No major changes should be done to dietary habits, only minor changes are expected to accommodate the increase in energy consumed.
Timepoint [5] 373185 0
At baseline and after each dose (weekly for 8 weeks).
Secondary outcome [6] 373187 0
Plasma insulin
Measured by a pathology laboratory.
Timepoint [6] 373187 0
At baseline and after each dose (weekly for 8 weeks).

Purpose of the study
Prevention
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
There will be no concealment. This is a sequential dose clinical intervention, all participants will consume all dose in a sequetial dose.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding
Open (masking not used)

Safety/efficacy
Statistical methods / analysis
Statistical analysis will be performed to determine the adequate dose of medium chain fatty acid oil to be consumed. The adequate dose will be determined by a function of tolerance and effect to biomarkers. The ideal dose will not affect adversely biomarkers for cardiovascular health and will cause the least side effects with the lowest severity or no side effects to at least 90% of the population studied.
IBM SPSS Statistics 19 software package will be used for the statistical analysis.
