Sodium #

• Magnesium is antagonistic to it.
• Excess sodium enhances Calcium excretion
• Sodium increases absorption of sugars in the intestine
• High sodium increases bone turnover and reduces bone mineral density. Having a correct Potassium to sodium balance decreases excessive Calcium excretion; an imbalance can lead to “high sodium”, which leads to calcium excretion which fucks up the bonez

• Sodium deficiency/too much liquid causes Prolactin spikes which lead to an itchy scalp.

Restriction #

• https://raypeatforum.com/community/threads/optimal-sodium-intake-is-at-least-230-higher-than-rda.4860/ 63mg/kg is a good target, but a high intake can only do good.
• A sudden increase in take will lead to additional retention of water for a day or two, but the body will quickly adjust the rate of sodium excretion.
• Long-term effects of dietary sodium intake on cytokines and neurohormonal activation in patients with recently compensated congestive heart failure
  • Low-sodium: 1.8g/day; moderate: 2.8 for 12 months + furosemide, a loop diuretic.
  • The low-sodium diet showed a significant activation of neurohormones and cytokines and worsening the body hydration, whereas moderate sodium restriction maintained dry weight and improved outcome in the long term… suggest a surprising efficacy of a new strategy to improve the chronic diuretic response by increasing Na intake and limiting fluid intake.
• Effect of dietary salt restriction on urinary serotonin and 5-hydroxyindoleacetic acid excretion in man
  • During the low-salt diet, 24-h urinary excretion of Serotonin increased by 42%, accompanied by a 52% rise in the excretion of 5-HIAA. Salt restriction also increased Noradrenaline excretion by 77% and vanillylmandelic (VMA) excretion by 40%.
• Effects of sodium supplementation during energy restriction on plasma norepinephrine levels in obese women.
  • The upright plasma NE values were highest in the 0 Na fast subjects, but lower after the saline infusion
