Salt appetite and sodium intake in humans are controlled in part by taste. A distinction can be drawn between salt appetite that occurs when the organism is sodium deficient (in need) and when the organism has sufficient sodium stores (non-need) but continues to ingest salt. Although the latter case is most relevant to human sodium consumption, little is known about its physiologic, developmental, and experiential bases. Recent studies show that changes in dietary sodium consumption are followed by taste changes. Moderate decreases in dietary sodium of 2 months or more are followed by a decrease in the concentration of salt in food judged most pleasant.
人类的盐食欲和钠摄入量部分受味觉控制。当机体缺钠（需要）时出现的盐食欲与机体有足够的钠储备（不需要）但仍继续摄入盐的情况之间存在区别。尽管后一种情况与人类钠消耗最为相关，但对其生理、发育和经验基础知之甚少。最近的研究表明，饮食中钠消耗的变化会伴随着味觉的改变。饮食中钠含量适度降低两个月或更长时间后，被认为最可口的食物中的盐浓度会降低。
