Now the big thing is with organically grown foods. They've found that just because farmers stopped growing foods using chemicals the soil upon which they grew non organic food still have the chemicals left in them which the supposed organics absorb. Dr Oz did a show on butters and he said pure butter is the best option, unsalted even better but....he also did a show with a guy who said it's not salt that drives high blood pressure. As a example he gave countries in the ME whose food had high salt content but their people didn't suffer from high blood pressure. Dr Oz brought on another doctor who basically called him full of shit....so in a case like this who you going to believe? We have to remember the biggest lie ever perpetrated on the public that it was fat that caused coronary disease when all along sugar was the biggest culprit.
There is no correlation between salt and high blood pressure as far as I know but, we get sold nonsense. The same with fat being bad while being pushed sugars or worse, sugar substitutes. It has been known for several decades sugar is the cause yet, who read the research?
Here in the US it's always been considered bad for people with high blood pressure. Here's a short explanation on it that I found:
Salt (sodium) is essential to our bodies. Normally the kidneys control the level of salt. If there is too much salt, the kidneys pass it into the urine. But when our salt intake levels are very high, the kidneys cannot keep up and the salt ends up in our bloodstream. Salt attracts water. When there is too much salt in the blood, the salt draws more water into the blood. More water increases the volume of blood which raises blood pressure.

When I was in my twenties a couple I know told me salt was one of the worse things you could use on food because so many foods already come with salt added. To much salt was just plain bad. I took them at their word and stopped adding salt as a topper to already cooked foods and use it only to season food when cooking. I do like to add a touch of salt to a deviled egg or tomato but otherwise use it sparingly and try to season foods or meats with other herbs or spices. Like I put garlic in mashed potatoes , or top it with turmeric, turmeric is pretty good on top of eggs too. When you quit using so much salt and you go out to eat you can really taste the salt in the food, I found this particularly true of hamburgers. They claim sea salt doesn't have quite the same bad rap but now there's been articles by health organizations that they've been finding bits of plastics in some sea salts from so much plastic being in the ocean. Plastic is a big concern digested into the body for young kids, some scientist claim it can have a effect on their reproductive ability when they get older. My motto is this: If you are going to have a bad habit pick one that will kill you rather quick, those habits that are going to lead you into ill health dependent upon pharmaceutical companies and drain your pocket book will make you wish you had of pick one that killed you quick instead.
It is funny that in moat places, suicide is illegal but, smoking isn't. Isn't it just a slow form of suicide?
I don't actually eat much salt and don't add it to cooking, haven't for years. But from what I have heard, the correlation between heart disease and salt intake is very low. When it comes to heart disease and saturated fat, it is only when ther is sugar present in the system that it becomes a problem. Perhaps it is the same with salt and some other enzyme created by something else. My point is that the system is highly complex and adding in more complexity is inevitably going to lead to more points of potential weakness. It doesn't matter what the system is, complexity adds risk.
