A working group in 2019 from the International Agency for Research on Cancer determined there to be "sufficient evidence" to suggest carcinogenic properties of isobutyl nitrite on experimental animals, and because they could not find any sufficient studies regarding its carcinogenic effects on humans, they determined that isobutyl nitrite is ...
The nitrate-nitrite-nitric oxide pathway elevates nitric oxide through the sequential reduction of dietary nitrate derived from plant-based foods. [13] Nitrate-rich vegetables, in particular leafy greens, such as spinach and arugula , and beetroot , have been shown to increase cardioprotective levels of nitric oxide with a corresponding ...
