The study that was commissioned by the American CDC (Center for Disease Control) reviewed dozens of previous research papers of varying types and tried to find some correlation in the results. Interestingly they found that a higher intake of salt didn't actually lead to increase health concerns. In fact, some of the evidence suggests that having a salt intake that is too low could actually be harmful. Interesting! But why is that?
Some theories point the blame at the type of salt that we eat nowadays. Table salt is not the same as salt we used to eat. It's not a natural product that our ancestors' bodies would have evolved with. Table salt is a mix of just 2 minerals - sodium and chloride. Natural salt can contain a mix of over 50 minerals. That's a startling difference and is thought to have an impact on your body.
The thought is that it's the lack of minerals in our diet to balance out the levels of sodium chloride in our modern salt intake that causes the problem. It's compounded by things like fizzy drinks - we've already discussed how they can actually drain your body of minerals. With the imbalance in minerals your body has to work much harder, in adverse conditions, to keep you alive and functioning well. If this happens over a longer period of time then your body will start to 'wear out' and this is when the diseases start to rear their heads.
Our advice is to do what we do. Don't be scared of salt. Actively add it to meals for flavour and to increase the mineral content of your food (which has also dropped in recent years due to intensive farming). But it needs to be natural salt. Replace your sodium chloride table salt with some good quality, unprocessed mineral salts (like sea salts). You never know, you may get rid of some symptoms of illness you have put up with for years. It could help improve asthma, lung diseases and allergies!
Just like always - eat natural, unprocessed foods that were available during our evolution and it's a good bet you can't go too far wrong! Avoid highly processed alternatives.
