Summary

This study evaluates the potential anti-inflammatory effects of inorganic dietary nitrate in a model of acute inflammation relevant to cardiovascular disease (CVD).

Green leafy vegetables contain large amounts of inorganic nitrate, and research suggests that this nitrate has beneficial effects on the heart and blood vessels. The Ahluwalia Group have shown anti-inflammatory benefits of inorganic nitrate in pre-clinical models of CVD, early mechanistic studies in healthy volunteers, and in patients with hypertension, hypercholesterolaemia and those suffering acute heart attacks that translate to cardiovascular benefits. Understanding the mechanism of how this is achieved may open new therapeutic options in CVD.

The Investigators therefore wish to explore whether inorganic nitrate might alter inflammatory responses using a blister-model of acute skin inflammation. This study is a randomised control trial with parallel limbs where half of patients receive nitrate-rich beetroot juice, and the other half a nitrate-deplete placebo beetroot juice.

Conditions

Interventions

DIETARY_SUPPLEMENT

Nitrate-rich Beetroot Juice

The beetroot juice contains approximately 100kcal per 100mL of juice, equivalent to a glass of orange juice; the volume of juice per day for the study is 70mL. Volunteers will be informed that an average woman weighing 65kg should not consume more than 2000kcal per day, and an average man of 75kg not more than 2500kcal per day.

DIETARY_SUPPLEMENT

Nitrate-deplete Beetroot Juice

See description of placebo juice in "Arms" for comparative information. The beetroot juice contains approximately 100kcal per 100mL of juice, equivalent to a glass of orange juice; the volume of juice per day for the study is 70mL. Volunteers will be informed that an average woman weighing 65kg should not consume more than 2000kcal per day, and an average man of 75kg not more than 2500kcal per day.
