Eating a lot of salt results in water retention which can dilute glucose concentration. Thus, you may transiently appear to be hypoglycemic while you have retained water since a glucometer measures the concentration of glucose in serum rather than total amount.

To elaborate with a bit better explanation, a quote I found:

"A diet with excessive salt intake has been found to contribute to hypoglycemia. Salt causes a loss of blood potassium that leads to a drop in blood sugar. Potassium is necessary to correct sugar metabolism abnormalities. Excessive salt intake causes potassium losses, which results in a drop in the blood sugar level. The low blood sugar level triggers the onset of stress, causing a lot of potassium to be lost in the urine and for sodium, as well as water, to be retained in the system."

Eating fat slows the metabolizing of sugar. Learned that during my gestational diabetes. Afraid of an insulin spike? Pour on some more butter! Salt, however, I have no knowledge of. It'd be nice to have another tool in the arsenal.

I don't know, but according to Ray Peat and Lita Lee, both biochemists, salt does have this effect. That's one of the reasons they recommend putting a bit of salt in your fruit juice, if you eat any. You might want to check their sites for their reasoning on this.

I am wonder the same ... "Does sodium intake decrease blood sugar?" I have been dieting of late and so decreasing my sugar intake. However this morning I had a cup of coffee with sweetner for the first time on my diet. I struggle with low blood sugar sometimes and am fully confident in my abilities to recognize LOW blood sugar - hot, sweaty, uncomfortable, need to lay down, light headed, hypotension, increased pulse. - However this is not how I felt! I felt warm but not sweaty at all! I was uncomfortable but not light headed. Actually I had a bit of headache (a sign of hyponatremia/low sodium). My pulse was not racing. It was 58-60; my norm is 54-62. I thought about having something sweet, but the thought of sugar just made me feel kinda "sick". I decided I was craving something salty. I know that Potassium (K) helps with insulin to bring glucose/sugar into the cell from the blood stream. I also know that K and Sodium (Na) are inversely opposite in levels; when K is high in the blood stream, Na is low and vice versa. Na is actually needed to bring K into the cell reference the KNa pump.(K likes to be in the cell and Na likes to be out of the cell in the blood stream.) So I thought putting all these truths together might make me feel better if I was indeed experiencing hyperglycemia. (I have not been taught that Na lowers K, but since I have been taught the other truths ... It just kinda made since to me.) So I thought if K with insulin that my body makes helps to bring glucose into the cell and if Na helps K go into the cell then Na would ultimately help insulin go into the cell. So increasing my Na intake would decrease my blood sugar, and I would feel better. After salty green beans and a peanut butter sandwich (Yes, I know 1) weird combo and 2) peanut butter and bread also have carbs/sugar it is complexed carbs and in combo with the Na I would prevent too much of a drop in blood sugar) I started to feel so much better. My headache went away almost immediately, and I felt completely better by 1 to 2 hrs later.

So does this prove that Na intake decreases blood sugar? I'm not sure, but I can tell you the next time I feel like that and sugar doesn't appeal to me ... I'm going for the salty!

Himalayan salt is especially good at regulating blood sugar. This kind of salt is extremely healthy for the body: http://naturalhomecures.net/crystal-salt/diseases/a-to-h/vital-element-for-balancing-sugar-levels-in-diabetics
