Sodium chloride vs potassium chloride: Which One is Better for Your Heart ?
In water softeners, sodium chloride is the most-used
salt form. It is the cheapest and has been used effectively for many years.
However, it is not recommended for anyone with heart disease. This is because
it introduces too much sodium to your body.
There is an alternative called potassium chloride.
It is more expensive but it lasts longer because you don't have to use as much.
When you make the switch, you will have to adjust your water softener for
potassium chloride. You may be on the do this yourself using your manual or you
may have to call a plumber to make those adjustments.
It surprised me when, following my heart events, I
needed to make this change and yet I couldn't really find anything in the medical
literature to recommend it. It was another case of having to be your own
advocate.
Sodium chloride is a naturally-occurring mineral
found in the earth and comes from underground salt mines or solar evaporation
ponds. It’s the most commonly used salt in water softener brine tanks. When the
brine solution containing sodium chloride washes over the resin, the hard
mineral ions in the water are replaced with sodium. Sodium chloride brands are
commonly available in a variety of forms including blocks, crystals, pellets
and cubes. Beside the fact that it’s widely available, sodium chloride often is
the preferred softener salt because of the comparatively lower price.
Potassium chloride also is a naturally-occurring
mineral and is used primarily in agriculture. It works in softeners the same
way sodium chloride does but replaces the hard water minerals with potassium
instead of sodium. Potassium chloride is an essential nutrient for human health
and plays an important role in the functioning of organs, nerves and muscles.
It can be found in a wide variety of foods such as dairy products, meat, fruits
and vegetables. In addition, potassium chloride is important to the healthy
growth of plant life. Because extracting potassium chloride from the earth is
more costly than mining sodium chloride, potassium chloride is more expensive.
If you are on a sodium-restricted diets (and all
people with heart disease are) potassium chloride should be your choice. Potassium
chloride also may be the choice for those who are health conscious or concerned
about the environment.
Salt
substitutes use potassium chloride. People with kidney disorders should avoid
using salt substitutes because a dangerous build-up of potassium in your blood
can be harmful to your health.
There
are benefits to using potassium chloride:
- It is more environmentally friendly.
- It provides a fuller soap lather and cleaner, brighter, fluffier laundry.
- The backwash can be captured and used to water lawns and gardens. because potassium is a nutrient.
- It does not contain sodium.
One
thought is that residual amounts of either one will be left in the water after
the exchange process.
There
have also been studies that show we could use more potassium in our diets, helping
to lower the risk of stroke and high blood pressure.
