We need a certain amount of salt to live, but most of us eat much more than our bodies need. Getting too much salt can increase blood pressure, resulting in a higher likelihood of complications such as a stroke or . A low-salt diet can also lower blood pressure.

Most of the salt in our diet is found in processed foods. Examples of foods that contain a lot of salt include potato chips (crisps) and salty snacks, processed fish and meat products, and many different types of cheese. Bread, convenience foods, ready-made sauces and seasonings are often heavily salted too.

Fresh and unprocessed foods, on the other hand, are low in salt. They include things like fresh fish, fresh meat and many dairy products such as yogurt. Most fruits and vegetables are very low in salt – for example, there’s only 1 gram of salt in 13 kilograms (about 29 pounds) of tomatoes. Grain products like pasta or rice are also naturally low in salt. This is not true of processed grain products like bread or cornflakes.

How much salt is in ...

If you would like to reduce your salt intake, it’s helpful to have a general idea of how much salt there is in various foods.

    1 bread roll (45 g) 0.8 g
    Margarine (20 g) negligible
    Butter (20 g) negligible
    Yoghurt (small cup of 150 g) 0.2 g
    1 portion of cheese spread (30 g) 0.4 g
    1 slice of semi-hard cheese (at least 45% fat) 0.4 g
    1 slice of Gouda cheese (at least 45% fat) 0.6 g
    1 Portion of cream cheese (30 g) 0.3 g
    1 glass of milk (0.25 l) 0.3 g
    1 slice of salami (30 g) 0.8 g
    1 portion of liverwurst (30 g) 0.4 g
    1 portion of unprocessed meat (not cured or smoked) (150 g) 0.2 g
    1 portion of smoked herring (75 g) 5 g
    1 can of tuna in oil, drained (about 150 g) 1 g
    1 portion of fresh fish, e.g. cod (150 g) 0.3 g
    2 handfuls of roasted and salted peanuts (50 grams) 1 g
    2 to 3 handfuls of potato chips (60 grams) 0.7 g
    1 large carrot (100 g) negligible
    1 portion of rice cooked in lightly salted water (180 g) negligible
    1 portion of potatoes boiled in lightly salted water (250 g) negligible
    1 portion of noodles cooked in lightly salted water (200 g) negligible
    1 portion of fruit (125 g) negligible

    Tips for reducing your salt intake

    It is not easy to make long-term changes to your eating habits – after all, eating is one of life’s pleasures. The following tips could help you to make changes to your diet:

    • Season with herbs: Low-salt food doesn’t necessarily have to be bland. You can season it with fresh or dried herbs instead.
    • Gradually reduce your salt intake: How good something tastes to you is partly a matter of what you're used to – so it's often easier to gradually reduce the amount of salt you use over a few weeks instead of doing it all at once. That makes it easier to get used to the natural flavors and not feel like something is missing.
    • Choose low-salt alternatives: You can simply compare the salt listed on packaged foods.
    • Prepare healthy snacks: Many people like eating snacks like pretzels, salted nuts or potato chips when they watch TV, for example. These foods are not only very salty, but they are high in calories as well. Low-salt, low-calorie alternatives include unsalted nuts, fresh fruit skewers or freshly sliced vegetable sticks (carrots, celery or bell peppers) with a yogurt or sour cream dip.
    • Use potassium (low-sodium) salt: You can also lower your blood pressure by switching to low-sodium potassium salt. It is a special diet salt that replaces part of the table salt (sodium chloride) with potassium salt (potassium chloride). Potassium salt is more expensive than conventional table salt, though. Switching to potassium salt can prevent complications of high blood pressure. But talk to your doctor first if you have kidney disease or are taking medications that affect your potassium levels.
