研究概览
简要总结
The goals of the proposed research are to determine whether repeated exposure to a low sodium food will result in reduced preference for salt in that food among children; and to determine whether such reductions in preference are related to dietary intake of salt, taste receptor genotype, and anthropometric and physiological measures.
详细描述
This is a within- and between-subjects randomized controlled trial on children consuming either a low sodium or a higher sodium cereal over a 2-month period to determine if repeated exposure to the low sodium cereal is effective for reducing preference for salt in that food. Children will be genotyped for markers related to taste, dietary intake will be recorded, and anthropometric and physiological measures will be collected at baseline.

结局指标
主要结局
Relative Preference for Regular vs Low Sodium Cereal
时间窗: At baseline and after 8-week intervention
The number of children who preferred the taste of the low salt cereal when compared to the regular sodium cereal
Most Preferred Level of Salt Taste
时间窗: Baseline (time 0) and after 8-week intervention
Children were presented with pairs of broths with varying concentrations of added salt (0.16, 0.24, 0.38, 0.61, 1.05 M) (17) . The first pair of broths (0.24 and 0.61 M salt) presented were from the middle range of concentrations. Children were instructed to taste each sample within a pair for 5 seconds, to rinse between tastings, and then to point to the sample they liked better. Each subsequent pair of samples contained the concentration selected by the participant paired with an adjacent stimulus concentration. This pattern continued until the child either chose the same concentration when paired with both a lower and higher concentration in two consecutive pairs or chose either the highest or the lowest concentration twice consecutively. The entire task was repeated a, with stimulus pairs presented in reverse order. The geometric mean of the two concentrations chosen in the first and second series was calculated to determine most preferred levels of salt.
