Salt and Your Health: How Much Is Too Much, and How to Cut Back

Most of us eat far more salt than we need — much of it hidden in everyday foods. A practical guide to why too much salt matters, where it hides, and simple ways to cut back without bland food.

Salt makes food taste good, and we need a small amount to function — but most of us eat far more than we need, often without realising, because so much of it is hidden in everyday and packaged foods. Too much salt is a major, silent driver of high blood pressure, which in turn raises the risk of heart attack and stroke. The good news: cutting back is easier than you think, and your taste adjusts. Here is a practical guide.

Why Too Much Salt Matters

The main concern with salt is that it pushes up blood pressure — and high BP is one of the biggest, most silent risk factors for heart attack, stroke, and kidney damage. Because high BP usually has no symptoms, the harm from a high-salt diet builds quietly over years. For people who already have high blood pressure, heart, or kidney problems, cutting salt is an especially important part of managing their health.

Most of us eat well above the amount of salt we need, and the shared advice from health bodies is simple: most people should eat less salt. Cutting back is one of the most effective everyday steps for blood pressure and heart health.

Where Salt Hides

  • Packaged and processed foods — namkeen, chips, instant noodles, ready meals, packaged soups
  • Pickles, papads, sauces, and chutneys
  • Processed meats and salted/preserved foods
  • Bakery items and some breads (more than you'd guess)
  • Restaurant and street food, which is often heavily salted
  • The salt you add while cooking and at the table
The hidden-salt surprise Much of our salt does not come from the salt shaker — it is already in packaged and processed foods. So cutting back is as much about choosing fresher food and reading labels as about adding less at the table.

Simple Ways to Cut Back

  • Cook more at home with fresh ingredients (you control the salt)
  • Taste before you add salt; add a little less each week — your taste adjusts
  • Flavour with herbs, spices, lemon, garlic, and ginger instead of extra salt
  • Go easy on pickles, papads, namkeen, and salty snacks
  • Check labels and choose lower-salt options; watch out for "hidden" high-salt packaged foods
  • Rinse canned foods, and be mindful of salty sauces
A note on salt substitutes: "low-sodium" salts often replace some sodium with potassium, which is not suitable for everyone (e.g. some people with kidney problems or on certain medicines). Check with a doctor before switching if you have a health condition.

When to See a Doctor

Cutting salt is general healthy eating and needs no doctor. But it is especially important — and worth a doctor's guidance — if you have high blood pressure, heart disease, or kidney problems, where salt directly affects your condition. If you have not had your blood pressure checked in a while, that is worth doing, since salt and BP go hand in hand. For a tailored plan, a general physician (or dietitian) can help, and an online consultation is a convenient start. (See our guides on high BP, understanding BP readings, and heart health for more.)

A note on sources General education based on trusted public health nutrition guidance (WHO, NHS). It does not replace personalised advice from a doctor, especially with high BP, heart, or kidney conditions.
