Hey Marty!
Let’s put this in perspective with a few key points….
- If you look at your latest blood test, you will see the range of sodium considered normal is 134-144 mmol/L
In the study....
- the high sodium group get a meal with 65 mmol sodium, which equals 1,500 mg of sodium, which is the Adequate Intake (AI) for the day. So, they got a days worth of sodium at once to see if it had an a impact.
- the baseline levels of sodium were 139.6 for Low Sodium Group and 139.5 for High Sodium Group
- The high sodium meal increased serum sodium concentration within 60 min compared with the low sodium meals. The High Sodium groups level went from 139.5 to 141, and the Low Sodium groups went stayed at 139.6
Consuming a full days worth of salt in one meal and having serum sodium go up 1.5 mmol/L is not significant in anyway or really moving serum sodium level. In fact, it could be considered in the “error range”.
The study goes on to say….
“This study used an amount of sodium-chloride typical of that in current foods and single meals consumed in developed countries [31].However, to produce a change in serum sodium concentration of the magnitude observed in vitro studies it may not be physiologically possible with oral sodium loading alone, without adverse effects (e.g. nausea and vomiting). …..Compensatory mechanisms stimulated when serum sodium is raisedNot only is it not physiologically possible to make your serum sodium move, to do so would cause adverse effects and trigger compensatory measures to even prevent it happening
Let’s put this in another perspective, If you ate a whole days amount of food at once and your LDL went from 65-66.5 would you consider that an impact or relevant?
If you have hypo-natremia or hyper-natremia, it is not because of the salt in your diet.
