Test results for 41 salts
The right salt for everyone
Sometimes it has to be something special: Then, for example, fleur de sel salt blossoms on fine food surprise the palate with the typical crispy effect. For the pasta water, on the other hand, the cheap, good salt from the discounter does the trick. Do you suffer from high blood pressure? Then a low-sodium salt might be right for you. Our test shows the right product for every need. In our salt test, 17 out of 41 products have health benefits. The products differ mainly in smell and taste and in their contribution to covering the daily need for iodine, fluoride and folic acid. You will find out why iodine is so important when you unlock the test report.
Fleur de Sel, salt from the Himalayan foothills, ancient salt
Because of white gold. Pink salt from the Himalayan foothills and Persian blue salt add color to food. Such products – like fleur de sel – are usually not fine, but coarse. Stiftung Warentest examined the quality and composition of some of these salts. The test sheds light on whether they differ from conventional household salt – or are simply of culinary interest.
Dull and rubbery. This is how some salts smell if you have a very fine nose. Other salts in the test smell pleasant: they exude a touch of the sea. If errors in terms of taste and consistency are added to the fragrance note, this also affects the test mark.
Hardly any pollutants found, but microplastics
Salt is extracted from nature in a number of ways – concentrated from seawater, mined from underground tunnels, or boiled from underground salt lakes. Theoretically, the salt can therefore be contaminated with heavy metals such as lead, nickel and arsenic. We examined the chemical quality of the salts. Fortunately, it was good or even very good for all products.
In recent years, researchers have reported that microplastics can contaminate sea salt – tiny particles and fibers that look like microplastics were also noticed in some products in this test. The Stiftung Warentest classifies the findings. According to the current state of knowledge, they are not a reason for a health alarm.
Salt with the right amount
It doesn’t work without salt. Everyone needs to consume some of it to regulate fluid balance and blood pressure. Processed foods such as bread, cheese and ready-to-eat products make up part of the intake, while loose salt for the home covers the other part.
However, too much can lead to high blood pressure in some people. Because table salt, which consists of around 99 percent sodium chloride, binds water in the body. The more liquid circulates, the greater the pressure on the vessels. If you already have high blood pressure, low-sodium salts can be an alternative. Our test report reveals what they are good for – and how much salt is good for us humans.
Tip: If you want to check your blood pressure regularly, you should have a measuring device in your home. You can find good products in the current test of blood pressure monitors. The guide to the end of high blood pressure provides information on how high blood pressure can be identified, treated and reduced. High blood pressure medicines rated by our drug experts also help.
