The objective was to study the effect of 6-n-propylthiouracyl (PROP) taster status on macronutrient selection. Thirteen PROP nontasters (PNT) and 23 PROP tasters (PT) were offered three ad libitum lunches in a random order: a high-fat (HF; CHO/P/F: 30/10/60), a high-carbohydrate (HCHO; 80/10/10), and a mixed (MIX) lunch consisting of products of the HF and HCHO lunch. PT compared to PNT ate relatively more fat (47+/-9 vs. 38+/-10%, P<.05) and less carbohydrate (45+/-9 vs. 53+/-10%, P<.05) from the MIX lunch. When dividing PT into supertasters (PST) and medium tasters (PMT), the same relation between PT status and macronutrient selection was observed (P<.05). The energy density of the food consumed was higher for PT than for PNT (P<.05). Protein, food (g) and energy (kJ) intake, appetite, and hedonic value were not different between PT and PNT. At the HCHO as well as HF lunch, no differences with respect to macronutrient selection, food and energy intake, appetite levels, and hedonic value between PT and PNT were observed. However, at the HF lunch, energy density of the food consumed was higher for PT than for PNT, but this effect was not observed during the HCHO lunch. Hunger and satiety scores did not differ between PT and PNT. The hedonic value was higher for the MIX lunch compared to the HCHO and HF lunch for PT as well as for PNT. In conclusion, PT ingest more of the HF foods than of the HCHO foods from a mixed lunch compared to PNT.
目的是研究6-正丙基硫氧嘧啶（PROP）味觉者状态对常量营养素选择的影响。13名PROP非味觉者（PNT）和23名PROP味觉者（PT）被随机提供三份随意享用的午餐：一份高脂肪（HF；碳水化合物/蛋白质/脂肪：30/10/60）、一份高碳水化合物（HCHO；80/10/10）以及一份由HF午餐和HCHO午餐的食物组成的混合（MIX）午餐。与PNT相比，PT从MIX午餐中摄入的脂肪相对更多（47±9%对38±10%，P<0.05），碳水化合物相对更少（45±9%对53±10%，P<0.05）。当将PT分为超级味觉者（PST）和中等味觉者（PMT）时，观察到PT状态与常量营养素选择之间存在相同的关系（P<0.05）。PT所消耗食物的能量密度高于PNT（P<0.05）。PT和PNT之间的蛋白质、食物（克）和能量（千焦）摄入量、食欲及享乐价值并无差异。在HCHO午餐和HF午餐时，未观察到PT和PNT在常量营养素选择、食物和能量摄入、食欲水平及享乐价值方面存在差异。然而，在HF午餐时，PT所消耗食物的能量密度高于PNT，但在HCHO午餐时未观察到这种效应。PT和PNT之间的饥饿和饱腹感评分没有差异。对于PT和PNT而言，MIX午餐的享乐价值高于HCHO午餐和HF午餐。总之，与PNT相比，PT从混合午餐中摄入的HF食物比HCHO食物更多。
