The cereal based baby foods which are from brands A, B and C were subjected to a one-way ANOVA (analysis of variance) test. Thus according to the results (P > 0.05), there are no statistically significant differences between the nitrate contents of the cereal based baby food brands. The mean values of nitrate of all the ten baby food matrices were also subjected to a one-way ANOVA.
The results clearly identified statistically significant differences (P < 0.05) between the mean nitrate values of the various baby food matrices studied. Table 4 shows a comparison of nitrate content in different vegetable based baby food categories in different countries. The average nitrate values of vegetable based baby foods in Fiji are relatively lower than other such studies carried out in Estonia, Spain, Portugal and Germany
