Description of intervention(s) / exposure
All participants will receive foods consistent with the Mediterranean diet, 50-75% of their daily intake. Participants will receive food delivered to their home each week by My Food Bag delivery company. This will consist of 5 main meals (participants can choose from the weekly healthy heart options) and extra food for lunches and breakfast including fish, cereals, fruit, vegetables, oil and bread. This food will be delivered weekly for 12 weeks. Participants are not given advice regarding the remaining two main meals each week. Participants will be asked to report each week how much they consumed and of what, using the online form at the time they order their next weeks meals.

Summary
Brief summary
The High Value Nutrition (HVN) National Science Challenge works with scientists and businesses to add nutritional value to fresh and processed food products for the benefit of consumers whether in New Zealand or elsewhere in the world. Funded by HVN, the investigators are leading the development and implementation of He Rourou Whai Painga, a long-term multi-centre dietary intervention study that will explore whether consumption of high quality New Zealand F&B products in an adapted Mediterranean-style dietary pattern improves metabolic, cardiovascular, and wellbeing profiles in people at risk of cardiometabolic disease. The current proposal describes a pilot study that will be used to finalise the study design, power calculations, and final methodology of the main intervention study, He Rourou Whai Painga.
