Burger and Beetroot Study - Lipid Oxidation Study
A study testing Burger and Beetroot Study in people with Oxidative Stress, run by University of Aberdeen at 1 site in United Kingdom.
Trial summary
Consumption of "ready meals" and other convenience foods are rapidly increasing. However, their nutritional value is problematical. For example, many are high in fats which are potentially oxidisable resulting in the formation of toxic end products. Read more about this study

About this study
Official title: Lipid Oxidation of Ready Meals: Reformulation With Antioxidant Phytochemicals
Consumption of "ready meals" and other convenience foods are rapidly increasing. However, their nutritional value is problematical. For example, many are high in fats which are potentially oxidisable resulting in the formation of toxic end products. Consequently the aim of this study is to assess whether consumption of "ready meals" rich in certain fats leads to a post-prandial increase in lipid oxidation products in plasma and whether this can be ameliorated by reformulating the meals with natural extracts rich in phytochemicals with potential antioxidant activity in the stomach
Read the detailed description
Many of these lipid oxidation products such as malondialdehyde are known to be genotoxic and potentially detrimental to health. Consequently the aim of this study is to assess whether consumption of "ready meals" rich in certain fats leads to a post-prandial increase in lipid oxidation products in plasma and whether this can be ameliorated by reformulating the meals with natural extracts rich in phytochemicals with potential antioxidant activity in the stomach.
Diet design requirements:
The basic "ready meal" is a turkey burger consisting of
- 50% fat
- 20% protein
- 30% carbohydrate.
However, there are four experimental forms of the burger.
- The fat is unsaturated (stripped corn oil)
- The fat is saturated (lard)
- The fat is unsaturated and the diet also contains a beetroot extract at a concentration of 10g/100g.
- The fat is saturated and the diet also contains a beetroot extract at a concentration of 10g/100g.
Beetroot (http://www.kanegrade.com/powders.htm) has been selected for the burger reformulation as it is a Scottish product rich in phytochemicals with potential antioxidant efficacy. An additional benefit may a blood pressure lowering effect. Initial taste tests indicate acceptable palatability.
All other components of the burger are formulated to be as similar as possible.
Fatty acid profiles and the "basic eight" used on food labels will be determined on the diets. Susceptibility of the diets to oxidise will be assessed using RANCIMAT.
Ready Meal Intervention:
This will be a latin square format whereby each volunteer consumes 4 treatments on separate occasions. This is a powerful design to assess whether incorporation of phytochemicals from Scottish products improves the health benefits of processed food as each volunteer acts as his/her own control. Volunteers will be randomly allocated to four groups
- Treatment A High polyunsaturated (PUFA) ready meal (ie. burger)
- Treatment B High saturated (SFA) fat ready meal
- Treatment C High PUFA ready meal incorporating food extract
- Treatment D High SFA ready meal incorporating food extract
There will be a washout period of at least 7 days between each treatment.
Volunteers:
Healthy volunteers aged 21 to 60 years will be recruited and attend HNU having fasted from 22.00h the previous evening on four test days. On arrival, they will be asked to provide a urine sample. The volunteers will then have a cannula inserted by a trained nurse and an initial baseline blood sample will be taken (volume 10 ml). The subjects will then be asked to consume the assigned breakfast within a 15 minute period. Water will be provided. Volunteers will then be requested to provide 10ml blood samples at 1h, 2h, 4h and 6h and 24 hrs. A 24 hr urine sample also will be obtained, starting the day of the test day. Blood pressure will be recorded at each time point.

- Have a known allergy to beetroot
- Are vegetarian or vegan
- Regularly take nutritional supplements

The record says: finished, as of the sponsor's last update on 23 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Lipid peroxides (time frame: up to 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2014.
