Too much salt in our diets can increase blood pressure, which in turn increases our risk of having a stroke or suffering with heart disease. Experts recommend we have no more than 6g salt a day (children need even less). 

But many of us still have considerably more than this. Many varieties of fish are naturally low in salt, such as cod, haddock, hake, coley and pollock. To keep intakes down, avoid adding salt or salty ingredients such as soy sauce, to food. Smoked fish and many varieties of tinned fish, together with some shellfish, can contain more salt so where possible check the salt content on food labels and opt for products that contain the least. Those with no more than 0.3g salt per 100g are low in salt.
