Salt

There are small changes you can make to cut down the amount of salt you eat. Over time, this will help to keep your heart healthy.

What is salt and what is sodium?

When we use salt to season our food, we use table salt. Table salt is also called sodium chloride. When you see sodium on food labels, it’s just another way of talking about the amount of salt in the food.

Some sodium in our diet is good because it helps our kidneys to control the amount of water in our blood. If we eat too much sodium, water is pulled back into our bloodstream. The more water in our blood vessels, the higher our blood pressure gets.

High blood pressure can put you at risk of developing heart and circulatory diseases such as:

Children should eat less salt than adults. The recommended daily intake of salt for babies and children depends on their age.

Some food labels call salt, sodium instead. Salt and sodium are measured slightly differently. The recommended daily sodium intake for adults is less than 2.5g per day.

How do I know how much salt I’m eating?

The labels on your food will usually have a nutritional information section. This section will show you how much of each nutrient is in the food, like the amount of salt. To see how much salt is in the packaged food, you can look at the ‘amount per serving’.

Some food labels have a traffic light system to help you see if the food has a low, medium or high amount of salt in it. If you reduce the amount of food you eat with medium (amber) and high (red) levels of salt, it will help you reduce your risk of developing high blood pressure.

--- Red - high
--- Amber - medium
--- Green - low

My food label says ‘per 100g’. How do I know how much salt I’m eating?

Some food labels might not say the ‘amount per serving’, they might say the ‘amount per 100g’. Most food labels that say ‘amount per 100g’ will use the traffic light system to help you track your salt intake:

Low Medium High
Salt 0g - 0.3g 0.3g - 1.5g More than 1.5g
Sodium 0g -0.1g 0.1g - 0.6g More than 0.6g

What foods are high in salt and sodium?

A lot of the food we eat already has salt in it. In fact, around three quarters of the salt we eat on a daily basis has already been added to our food before we buy it.

The amount of salt will vary between different brands and varieties. Check your food labels before you buy to help you choose healthier options.

These types of salts are usually less refined (less processed) than table salt. But their amount of sodium and nutrients are similar to table salt. They can still put you at risk of developing heart and circulatory diseases.

Some supermarkets sell low salt alternatives like LoSalt and Saxa So-Low, or their own brands. These salt substitutes have less sodium than normal salt. They can help you reduce your sodium intake, but they won’t help you kick the habit of eating salty or ready-made foods. The low salt alternative brands usually contain potassium. High levels of potassium are not recommended for people with existing health conditions. If you have an existing health condition, you may want to talk to your doctor before using a salt substitute.
