Inorganic nitrate, found in leafy green vegetables and beetroot, can help lower blood pressure and support heart health. Early experimental work has suggested that dietary nitrate supplementation, in the form of beetroot juice or potassium nitrate capsules, can reduce blood pressure and improve endothelial function. Consequently, concentrated nitrate supplements like beetroot juice have become popular. However, these supplements can be expensive, high in sugar, and not to everyone's taste. Since more than three-quarters of adults with high blood pressure live in low- and middle-income countries, it is important to find safe, affordable ways to add nitrate to commonly eaten foods.
The team at Queen Mary University of London has been developing nitrate-fortified products that may be more appealing to a wider population. With support from the food manufacturer Reading Scientific Services L
