If you have heart failure or high blood pressure, it is important to reduce the amount of sodium you eat. Sodium causes extra fluid to build up in your body. This extra fluid makes your heart work harder and leads to fluid building up in your legs and ankles, as well as in your lungs, making it difficult to breathe.
What is Sodium?
Sodium is a mineral found in salt. One teaspoon of salt equals approximately 2300 mg of sodium. Two-thirds of the salt in the Canadian diet is hidden in food.
What is a low sodium diet?
It is best to limit the amount of sodium you eat to 2000 mg or less per day from all food sources. This will help prevent the accumulation of extra fluid in the body.
Reading Nutritional Labels
Approximately 10% of the salt in our diet comes from sodium found naturally in foods, 10% from what is added by using the salt shaker, and 80% from when food is processed. Food manufacturers may change ingredients over time. That is why it is important to make it a habit to read the nutritional label. Reading nutritional labels is key to determine the sodium content of foods. The amount of sodium in food is listed on the package. It is important to learn how to read the Nutrition Facts panel.
What are the Steps to Reading Food Labels?
Compare the suggested serving size on the package to the amount that you actually eat – this can sometimes be very different. The label lists the amount of sodium in one serving and not the total amount of sodium in the entire package.
Look at the amount of sodium in mg per serving. Try to choose products with less than 200 mg per serving or 10% or less of the Daily Value per serving.
Ingredients are listed in decreasing order by amount. If an ingredient appears earlier in the list, that means there is more of it in the package. So make sure that if salt or sodium appears, that it is near the end of the list. Sometimes the salt can be hidden, look out for these ingredients: sodium, monosodium glutamate (MSG), brine, sodium nitrite, sodium propionate, baking soda, and baking powder.

What to do when dining out?
