Summary

Blueberries are rich in the content of a variety of biologically active chemicals that contribute to their health properties. The consumption of blueberries has beneficial effects on vascular function and brain health and function. Blueberries are present in human diet in a number of forms, but the investigator do not know which form is best for health and why people respond differently to eating blueberries.

The aim of the present study is to assess the effects of 1 week's supplementation of whole blueberries or freeze-dried blueberry powder or encapsulated blueberry components on vascular function and brain health and function. Investigators will then categorise participants as those who have large effects of the intervention (responders) and those that don't show much effect at all (non-responders). Then the investigators will look into the role that genes play in this response and determine if metabolism is similar in these groups of participants. Any changes in participants' brain health and vascular function will be linked to these metabolic and genomic pathways, and this will help the investigators to further understand how blueberry consumption can benefit human health.
