Description of intervention(s) / exposure
The study will be conducted in Te Ohu Health unit at Massey University, Palmerston North. This study will be performed as a single-blind, randomised cross over study. One group (Group A) of the participants (6 participants) will receive placebo meal first and second group (Group B) (6 participants) will receive study meal first. Each study visit will last 8 hours.There will be one week wash out period between two visits.
All the study meals will be prepared in the product development lab, Massey University, Palmerston North. The study meal is MS apple puree (500g). The apple puree will be provided as a breakfast. Macronutrient matched placebo will be prepared from water and sugars presented in apple puree.
The trial will consist of a screening visit and 2 study visits (visit 1 and visit 2). The night before the study visits, participants will be asked to fast from 10 pm (overnight) till the start of the study (8 am). At the study visit a cannula will be inserted into their forearm through which the blood samples will be collected by by trained and approved individual.

Statistical methods / analysis
The study size was calculated using G power. The effect size needed for the G power calculations was calculated by subtracting the means and dividing the result by the pooled standard deviation of total phenolic content in plasma samples after apple juice consumption and control plasma samples after overnight fast based on the earlier published study. Study group size was calculated using a priori, t-test, difference between two means given effect size mentioned above, level of significance 0.05 and providing 80% power. Based on the result the minimal group size for this study is 10 participants, however considering 10% drop-out rate, we will recruit group of twelve participants (n=12) consisting of six males and six females.

Summary
Brief summary
Recent studies have suggested that apple consumption may reduce the risk of several types of cancer, due to their antioxidant and anti-inflammatory effects. However, the main phytochemicals present and subsequent antioxidant effects after apple consumption have not yet been fully characterised. Therefore, the purpose of this study is to evaluate the bioavailability of apple phytochemicals and the antioxidant effects of these phytochemicals in the plasma of healthy volunteers.

Who is it for?
You may be eligible for this study if you are aged between 18-45 years, a non-smoker, are a healthy weight, participate in no more than 10 hours of vigorous exercise per week, are able to consume apple, are pre-menopausal, and are able to not drink coffee or tea for 24 hours.

Study details
Participants will be randomised (i.e. allocated by chance) to receive either 500g of 'Monty's Surprise' apple puree, or a macronutrient-matched placebo puree. The puree will be consumed at 8am at the study site, following an overnight fast from 10pm the previous night. Participants will remain at the study site for a further 8 hours, where a cannula will be inserted into their forearm for collection of blood samples during this period. These blood samples will be used to assess the metabolites present in plasma, the antioxidant activity of phytochemicals, and glucose levels after consumption of the puree.

It is hoped that this study will identify main metabolites in the plasma after apple puree consumption, which will inform future cell culture studies. Moreoevr, this study may show that apple puree consumption increases antioxidant activity and reduces blood glucose levels, which may help to provide evidence for the mechanisms by which apple consumption reduces cancer risk.
