Chloride in Food

When it comes to essential nutrients, chloride may not be the first thing that comes to mind. However, this mineral plays a crucial role in maintaining proper fluid balance in the body and aiding in digestion and nerve function. Learn more about the sources of chloride in food and why it's crucial for your overall health.

What is Chloride, and Why is it Important?

Chloride in food is an essential mineral that helps maintain proper fluid balance in the body, aids in digestion, and supports nerve function. It is found in many foods, including table salt, seaweed, olives, and celery. Chloride is the ionic form of the halogen gas chlorine. With one electron added to a chlorine atom, chlorine becomes a negatively charged ion with entirely different chemical and physical properties than the poisonous halogen gas. Common salt is a crystal of sodium chloride, NaCl. Ionically, it is Na+Cl-. The negatively charged part, the Cl- ion, is the chloride. We need this mineral in our bodies, so eating salty food is important, but not in excess.

Is Too Much Chloride Bad For You?

Be aware that processed foods contain a lot of salt, so avoid them if you can. You don’t want too much chloride in food. The salt acts as a flavor enhancer that people like, which, like sugar, makes processed foods big sellers. So, is salt really as bad for you as many nutritionists claim? The simple answer is TOO MUCH sodium chloride or table salt is no good for you, but chloride isn’t. You see, there are other chloride salts in food, such as potassium chloride.

Potassium chloride

Some supplements and processed foods contain potassium chloride, which may help lower blood pressure, according to a study reported by the National Library of Medicine. Potassium chloride is used as a thickener, stabilizer, firming agent, and flavor enhancer in many processed foods. These include chocolate milk and eggnog, processed cheeses, creams, condensed milk, powdered milk, yogurt, puddings, and spreads made with dairy fat. However, without enough chloride, you may experience dehydration, muscle cramps, and other health issues. So, while it may not be as well-known as other nutrients, chloride in food is still an essential part of a healthy diet.

Chloride in the Stomach

Chloride works with sodium to regulate the amount of water in and around cells. This is important for proper hydration, as well as for maintaining blood pressure and electrolyte balance. Chloride also aids digestion by helping to produce hydrochloric acid in the stomach, which is necessary for breaking down food. Additionally, chloride in food supports nerve function by helping to transmit electrical impulses throughout the body. While chloride is found in many foods, it is essential to consume it in moderation, as too much can lead to health issues such as high blood pressure.

Is Chloride an Electrolyte?

Understanding the role of chloride as an electrolyte is crucial for maintaining a healthy body. Electrolytes are essential for maintaining proper fluid balance, nerve function, and muscle contraction. Chloride is one of the major electrolytes in the body.

What are the benefits of maintaining proper chloride levels in the body?

Maintaining proper chloride levels in the body is crucial for overall health and wellness. Chloride helps to regulate fluid balance in the body, which is essential for maintaining healthy blood pressure and preventing dehydration. Additionally, chloride is involved in transporting oxygen and carbon dioxide in the blood and helps regulate the body’s pH balance.

More About Chloride in Our Food

The body contains around 115 g of chloride ions or 11.5 percent of a kilogram. That’s a lot of negatively charged ions going around the body. That chloride level is kept constant by the excretion of excess salts in sweat, stools, and urine. Chloride with sodium works outside the cells, while chloride with potassium works inside the cells. That’s the difference. But together, they regulate the body’s fluid, electrolyte, and pH balance (acid/alkaline). Chloride also cleanses body wastes in the liver. Due to the widespread availability of chloride in food (table salt, seafood, fruits, vegetables, kelp, and naughty processed foods), chloride deficiency is scarce, although excessive vomiting could cause that.


The RDA (Recommended Dietary Allowance) for chloride is 800 mg. That’s the average amount of chloride which should be provided per head to a group of people. The UK’s RDI (Recommended Daily Intake) for chloride is 2,500 mg. That's 2.5 grams. That’s the amount that meets the nutritional needs of all healthy people. By the way, you may come across DRV in dietary labeling. That’s the Dietary Reference Value, a guidance on high intakes, and is the average requirement for a normally distributed population. There is no need to supplement with chloride!

The 3 Surprising Truths About Chloride

So now you know what chloride is. The three surprising truths are:

  • The body always excretes excess chloride.
  • We need the stuff for stomach acid (hydrochloric acid, pH 1).
  • Table salt is not the only source of chloride.
