We don't have salt in the house usually, as we don't really like it, and I thought there was enough salt in stuff like bread, crisps, pasta sauces etc.
But I saw a specialist today (I have been diagnosed with CFS) who confirmed I have something called orthostatic intolerance, where I get dizzy on standing due to rocketing pulse and low blood pressure.
Apparently adding a bit more salt (as well as drinking more water, which is easy) helps a lot of his patients with this symptom.
But I actually don't really know how to use salt. I don't really like it if meals taste too salty (say if we have bacon, we usually rinse it first!) so I'm not really sure how to increase my intake, other than eating more crisps!
My recommendation would be to get some posh salt. You would be surprised at what a difference it makes. We use Fleur de Sel (sorry I don't know what it is called in English) it is a sea salt, but it flakes in your fingers so you don't need a mill. It tastes much nicer than ordinary salt.
Frenchfancy, fleur de sel isn't available much in the UK (sooo delicious though) but Maldon is a very good alternative. You're quite right - I hate 'table salt' but love Maldon (and in fact now almost certainly eat far too much salt as a result of buying it!)
Rather than just adding plain salt to food you could try garlic salt or celery salt. I love celery salt and probably use far more than I should. It's lovely added to soup or cheese sauce. Or anything really!
