Salt Facts

  • Salt is one of the oldest and most ubiquitous food seasonings used around the world.
  • Salt is sodium chloride (40% Sodium 60% Chloride)

  • Higher salt intake can be needed for people who live in hot countries, athletes or people who profusely sweat.
  • Whilst athletes salt requirements can largely differ the baseline recommendation is 500-700mg of sodium per hour of strenuous activity. And upwards of 2000mg if you are unconditioned or sweat profusely.
  • Too much salt can cause high blood pressure (hypertension) which can exacerbate heart disease.
  • For the average person 75%, of their salt intake comes from processed foods & 20% from animal products and 5% added as a seasoning.
  • Some people and populations are more sensitive to salt intake and therefore more prone to blood pressure related heart disease.
  • Sodium plays a key role in healthy nerve and muscle function, also maintaining a normal fluid balance.
  • You may want to avoid evaporated sea salt as these can contain trace micro plastics and heavy metals.

Which Type of Salt Is Best?

Table Salt / Iodised Salt
Most of us use this in baking / cooking. This type is mined and Iodine has been added to the salt to prevent common deficiencies in people found all over the world. It’s a fine grain processed salt with an added anti caking age.

Kosher Salt
Often courser than other salts. No caking agents added which is why it can be courser. Chemically no different to any other salt.

Sea Salt
Less processed, comes from the ocean or lakes . However can contain micro plastics and other trace pollutions (Mercury, Arsenic, Lead).

Pink Himalayan Salt
This has had lots of hype over the last 10 years. Marketed to be superior. People claim it’s better for you because it has more mineral content, is less processed and therefore better to other salt. THIS IS UTTER RUBBISH. ALL SALT IS SALT.

Maldon Salt
Often large flakes, chemically no different to any other salt.


The added / naturally occurring minerals found in different types of salt are so small they really don’t have an impact on your health at all. The chemical make up of all salt is exactly the same. Don’t be suckered in by marketing and waste your money on “posh” salt.
