Special Issue Information
Dear colleagues,
This Special Issue addresses how and why salt appetite affects salt intake, selection, restriction, reduction, policies, and health. It is not about the effects of salt.
For many animals, salt appetite, or rather sodium appetite and sodium hunger, are life-preserving behaviors aimed at ingesting sodium to preserve or restore health.
Humans differ from animals in salt intake behaviours—we seem incapable of seeking it when in need, almost never eat it, invariably take it with food, rarely with drink, and ingest only NaCl, whereas for animals, any source of sodium will do. Hence, for humans, “salt appetite” is the predilection only for NaCl, and only as a flavor.
What are the origins of the appetite, its adaptive value, what causes us to overeat salt, and why is it the dominant seasoning of our diet? Do its taste-enhancing effects really account for its extraordinary and extant use, and if so, how is it adaptive? Why, of the five senses serving the infinite variety of tastes, is one exclusively devoted to the sodium ion? Beyond the little and sufficient sodium an omnivore diet supplies, evidence is scarce for the benefits of a salt appetite. However, it is a powerful incentive which we have little ability to regulate.
Manuscripts describing original research, reviews, or theory related to salt appetite as it relates to the above issues are welcome.
