Nitrate and nitrite content of frequently consumed grains,
legumes and nuts are reported in Table 4. Our analysis determined
a mean 0.6 mg 100 g1 for nitrite content and 24.3 and 59.6 mg
100 g1 mean nitrate levels for rice and barley, respectively. The
inter-quartile ranges (IQRs) of nitrate and nitrite were 39.1–
67.4 mg 100 g1 and 0.19–0.34 mg 100 g1 in industrial breads, and
were 29.3–64.7 mg 100 g1 and 0.17–0.39 mg 100 g1 in traditional
breads.
