"Several national and international agencies recommend individual dietary sodium intakes of no more than 100 mmol/day (6 g salt/day) and in some
cases no more than 65 mmol/day (4 g salt/day). Two WHO expert consultations recommended that the population average for salt consumption should be < 5 g/day (WHO, 1983; WHO/FAO, 2003). While well below the average salt consumption in most countries, this recommendation reflects a pragmatic compromise since well-conducted trials clearly indicate that even greater sodium reductions (to 50–60 mmol/day) would achieve greater health benefits. (Denton, 1982; WHO – International Society of Hypertension, 1999; Sacks et al, 2001; He & MacGregor, 2004) Additionally, numerous countries worldwide have set adequate intake levels for sodium. In Australia and New Zealand the adequate intake for adults for sodium was set at 460–920 mg/day (20–40 mmol/day) to ensure that basic nutritional requirements are met and to allow for adequate intakes of other nutrients (Nutrient Reference Values for Australia and New Zealand, 2005)."

This compromise is a pact with the enemy! Weapons is delivered for the entropy law.
