SUMMARY: This post is all about the salt controversy and discusses Salt: How much, Autoimmunity, & Iodine Deficiency. In sum, studies now show salt limits that are within a moderate salt consumption range (between 2,645 to 4,945 mg per day), reduces the risk of death or a serious event such as a heart attack or stroke and below or above these limits has increased risk of such. Studies now show autoimmunity associations with ordinary table salt through Th17 releasing up to 10x more cytokines when exposed to refined salt. Last, some groups have borderline iodine deficiency whereas other groups are high (children). Also included is how much salt do we really eat and a heads up: Those eating a Whole Foods diet may not be getting enough salt to be in that optimal bell curve range (between 2.645 to 4,945 mg per day).
