How Much Salt Is Safe With High Blood Pressure?
The World Health Organization recommends that adults eat less than 5 grams of salt a day, which is about one level teaspoon in total, including salt already in food. Many Indians eat much more than this, mainly from cooking salt, pickles, papad, snacks and packaged foods. Reducing salt can lower blood pressure and help BP medicines work better.
Quick answer
- Aim for less than 5 g of salt per day, or as advised by your doctor.
- Most salt comes from hidden sources such as pickles, papad, chutneys, namkeen, bread, instant noodles and restaurant food.
- Cutting back gradually, cooking with herbs and spices, and reading food labels can help lower BP within weeks.
Why Does Salt Raise BP?
Salt contains sodium, which makes the body hold more water. This increases the volume of blood and raises pressure on artery walls. Some people, including many with diabetes, kidney disease or older age, are especially sensitive to salt.
Where Does Hidden Salt Come From?
At home
- Extra salt while cooking and at the table
- Pickles and papad
- Chutneys and dry powders
- Salted buttermilk and lassi
- Baking soda in some recipes
Packaged foods
- Namkeen, chips and bhujia
- Instant noodles and soups
- Bread, biscuits and bakery items
- Sauces, ketchup and soy sauce
- Processed meats and cheese
Eating out
Restaurant and street food often contains high salt.
How to Cut Back on Salt
Reduce gradually
Taste buds adjust in a few weeks. Reduce salt slowly so food still tastes good.
Cook smarter
Use lemon, garlic, ginger, coriander, mint, cumin and pepper for flavour.
Limit high-salt foods
Keep pickles and papad occasional, not daily.
Remove the salt shaker
Avoid adding extra salt at the table.
Read labels
Check sodium on packets. Choose lower-sodium options.
Eat more potassium-rich foods
Vegetables, fruits and pulses help balance sodium, unless you have kidney disease and your doctor advises limits.
Be careful with salt substitutes
Some contain potassium and are not safe for people with kidney disease or on certain medicines. Ask your doctor first.
Does Rock Salt or Pink Salt Help?
No. Rock salt, pink salt and sea salt contain similar sodium to regular salt. The amount matters more than the type.
How Soon Will BP Improve?
Many people see a drop in BP within a few weeks of reducing salt, especially when combined with other healthy habits.
Key Takeaways
- Aim for less than 5 g of salt a day.
- Hidden salt is common in Indian foods.
- Pickles, papad and packaged snacks are major sources.
- Herbs and spices add flavour without salt.
- Rock or pink salt is not a healthier alternative.
