What to keep in mind when you go grocery shopping:
Go for reduced-salt, unsmoked bacon and try to avoid cured meats and fish, which can be high in salt.
Buy canned vegetables without added salt.
Tomato-based sauces are often lower in salt than cheesy sauces or those containing olives, bacon or ham.
Choose fruit or vegetables such as carrot or celery sticks for snacking. If you are going to have crisps or crackers, check the label and choose the ones lower in salt.
Go easy on soy sauce, mustard, pickles, mayonnaise and other table sauces, as these can all be high in salt.
Cook with less salt:
Use black pepper as seasoning instead of salt. Try it on pasta, scrambled eggs, pizza, fish and soups.
Add fresh herbs and spices like garlic, ginger, chilli and lime in dishes.
Make your own stock and gravy instead of using cubes or granules, or look out for reduced-salt products.
Try baking or roasting vegetables such as red peppers, tomatoes, zucchini, fennel, parsnips and squash to bring out their flavor.
Make sauces using ripe flavorful tomatoes and garlic.
