Assault on salt
Another thing we can do to help maintain a healthy blood pressure is to cut down on the amount of salt in our diet – health experts recommend we have less than 6g a day*. Many fresh and frozen fish are naturally low in salt so can be a good choice (although you should avoid adding salt or salty ingredients to them such as soy sauce). Smoked fish and many varieties of tinned fish 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 considered to be low in salt.
