Influence of dietary nitrate on nitrite content of human saliva: possible relevance to in vivo formation of N-nitroso compounds
B Spiegelhalder, G Eisenbrand… - Food and cosmetics …, 1976 - Elsevier
Vegetables and vegetable juices with concentrations of nitrate between 27 and 4031 ppm
were ingested by 11 volunteers in 30 experiments. Variations of nitrate and nitrite
concentrations in saliva were determined for up to 7 hr at intervals of 30 or 60 min. The
increase in the amount of nitrate secreted by the salivary glands was found to depend
directly on the amount of nitrate ingested. Nitrite concentration in saliva correlated directly
with salivary nitrate content. This suggests that there is a direct relationship between the …
