People living in rural areas are prone to move to urban cities experiencing a dramatic change in the type of protein consumed. However, it is not know if those changes are associated with changes in the plasma amino acid concentration, especially the branched chain amino acids. Thus, the aim of the present study was to evaluate, in a rural Mexican population, the plasma amino acid profile after consumption of typical Mexican rural or urban diet.
We evaluated the plasma amino acid concentrations of women from a rural population at 0, 30, 60, 90, 120, 180 and 240 min after ingestion of a typical Mexican rural or urban diet. Ingestion of a Mexican urban diet induced a higher increase in leucine, isoleucine, valine, phenylalanine, tyrosine and proline than ingestion of a Mexican rural diet in women from a Mexican rural population. Arginine, histidine, lysine, threonine, alanine, glycine and serine had the same area under the curve regardless of the experimental diet.

生活在农村地区的人们容易迁移到城市，其食用的蛋白质类型会发生巨大变化。然而，尚不清楚这些变化是否与血浆氨基酸浓度的变化有关，尤其是支链氨基酸。因此，本研究的目的是评估墨西哥农村人群食用典型的墨西哥农村或城市饮食后血浆氨基酸谱。
我们评估了农村人群中女性在摄入典型的墨西哥农村或城市饮食后0、30、60、90、120、180和240分钟时的血浆氨基酸浓度。在墨西哥农村人群的女性中，摄入墨西哥城市饮食比摄入墨西哥农村饮食导致亮氨酸、异亮氨酸、缬氨酸、苯丙氨酸、酪氨酸和脯氨酸的增加更高。无论实验饮食如何，精氨酸、组氨酸、赖氨酸、苏氨酸、丙氨酸、甘氨酸和丝氨酸的曲线下面积相同。
在墨西哥农村地区的女性中，摄入墨西哥城市饮食比摄入墨西哥农村饮食导致亮氨酸、异亮氨酸、缬氨酸、苯丙氨酸、酪氨酸和脯氨酸的增加更高。
