Summary of background and research design:
These authors also acknowledge that there are some risks of consuming nitrate and especially nitrite supplements. But, in fact, these authors point out that a common source for nitrate (and the source that has been used in their research studies) is beetroot juice, a natural product that is arguably safer than consuming straight nitrite or nitrate powder. Increasing the consumption of almost all fruits and vegetables is almost always positive, and can afford many health benefits other than increases in nitrate. These authors do not promote uncontrolled nitrite/nitrate supplementation but recommend an increase in the consumption of fruits and vegetables, especially those high in nitrates for those who would like to enhance circulation.
