Nitrate and Nitrite (or NOx) are compounds commonly found in many foods. A large body of evidence suggests that short-term consumption of dietary nitrate can have beneficial effects on markers of cardiovascular health such as blood pressure. Although some studies have tried to assess the potential benefits over-time, there are several limitations to the current methods used to measure nitrate intake. This study will try to create a method which can measure nitrate intake by measuring levels within urine.
