In a sub-population of Nigerian children in the southern rain forest of Edo State, we recently observed widespread relative insensitivity to the taste of sodium chloride (NaCl-salt). This prompted the present study, in which we measured taste recognition threshold to NaCl (30, 60, 120, 180 mM) and sucrose (15, 50, 100, 150 mM) in a group of fifth-and sixth-grade pupils in the northeastern semi-Sahel part of Nigeria, in order to observe the extent to which the findings cited above would apply to similar groups of Nigerians with different ethnic backgrounds in other parts of the country. Three hundred twenty-eight pupils (149 boys, 179 girls) from 9 to 18 years of age were involved. Five subjects were taste-blind to the highest concentration (180 mM) of NaCl. In addition, 44.5% of the study population did not taste NaCl until a concentration of 60 mm or higher was used. This distribution was influenced neither by gender (x2 = 2.75, df = 3, P = .43) nor age (r = .029, P = .60). In addition, only 33% of the population recognized sucrose sweetness at a sucrose concentration of 15 mm or lower. The remaining two-thirds of the population had sucrose threshold values of 50 mm or higher and neither gender (x2 = 3.09, df = 3, P = .379) nor age (r = .046, P = .41) influenced these findings. These results substantiate our earlier observations that relative taste insensitivity to salt (NaCl) may be common in Nigerian children. When compared to our earlier data, these results indicate that taste insensitivity to NaCl and sucrose may be more common in children in the northern parts of the country, thus suggesting that geographic location and ethnicity may be important variables in taste perception of NaCl and sucrose in adolescent Nigerians.
