21 Tips for Low Sodium Diet to Control Blood Pressure

 21 Tips for Low Sodium Diet to Control Blood Pressure

Today most of us are consuming an excess amount of salt than the requirement. The average per-person salt intake is too high, between 9 to 12 grams per day. Habitual intake of excess salt is the main culprit behind the widespread prevalence of hypertension (high blood pressure). To prevent and treat hypertension and other cardiac problems, taking a low-sodium diet is essential. Reducing the daily salt intake to not more than 6g (an approximate of 1 teaspoon of salt per day) is effective to reduce the blood pressure. (1

Hypertension-salt-sodium :The relation

Scientific studies confirm that a modest reduction in salt intake lowers blood pressure in people with hypertension in all age groups, and ethnic groups. Reduction in blood pressure reduces the risk of reducing strokes, heart attacks, and heart failure. (1,4,5) Therefore Reduction in salt intake is one of the most cost-effective interventions to minimize the incidence of heart disease and stroke.

Daily intake of an excessive amount of common salt (sodium chloride) introduces an excess amount of sodium in the body, which holds extra water, disrupting the fluid balance and thus increasing the blood volume and blood pressure. Elimination of excess salt by kidneys creates extra strain on the renal system which increases the risk of renal problems. Consistent high blood pressure is bad for brain health and increases the risk of dementia. (1,2,4)

The World Health Organization (WHO) recommended that an adult should consume less than 2000mg of sodium (sodium), or 5g of common salt daily. (3)

Basic functions of Sodium

  1. Sodium is an essential nutrient necessary for the maintenance of plasma volume.
  2. It regulates the acid-base balance of the body.
  3. It is needed for the transmission of nerve impulses.
  4. It is essential for normal cell functions. 
  5. It maintains our blood pressure.
  6. It regulates the distribution of water in different body compartments.

What are the sources of sodium in the diet?

Food processing reduces the potassium content of the food. A diet high in processed foods and low in fresh fruits and vegetables are often lacking in potassium and high in sodium. This puts the person at risk for raised blood pressure and related non-communicable diseases. (4)

 Table salt is pure sodium chloride, the prime source of sodium.

  • All types of edible salts like rock salt, black salt, pink Himalayan salt, low sodium salt is sodium chloride salt along with the little amount of other salts.
  • Sodium is naturally present in most animal foods such as milk, meat, and shellfish. 
  • Many condiments like soy and fish sauces are rich sources of sodium.
  • Processed foods such as bread, crackers, meats contain a high amount of salt.
  • Snack foods and fast foods usually contain high amounts of sodium. (4)

We should consume the above-mentioned sodium-rich foods in moderation.

Cooking tips: Tips to remember while cooking regular food

8. Reduce the use of salt in cooking. Remember human taste buds cannot detect a minor reduction in the salt of about 30%. So, reduce the amount of salt in your recipes gradually.

9. Mix table salt and black salt to reduce the sodium content. Commonly used table salt is pure sodium chloride (NaCl) whereas black salt is a natural salt, containing principally sodium chloride along with traces of other salts.1 g of common salt (sodium chloride) contains 390 mg sodium whereas 1 g of black salt contains 378.3 mg of sodium. You can mix 500 grams of common salt with 500 grams of black salt, mix well and use this for cooking purposes. This salt mixture is healthier than pure sodium chloride (table salt or common salt).

10. Don’t use salt in making chapati or roti.

11. Don’t add salt in freshly cut fruits like cucumber or banana. Enjoy the unique, original taste of the particular food.

12. Reduce the use of salt in making salad and soup.

Bottom Line

Hypertension is like an epidemic now. Sodium plays a huge role in controlling blood pressure. Sodium is an essential mineral required for our normal body functions. All types of salts like table salt, black salt, rock salt, pink Himalayan salts, etc contain principally sodium chloride (NaCl). So reducing salt intake is essential for keeping blood pressure under check. All-natural foods contain traces of sodium along with other minerals. But the processing of foods increases the sodium content of foods as a substantial amount of sodium is added to the foods during processing. Therefore, it is always better to choose freshly available fruits and vegetables rather than their processed counterparts. Be mindful while eating. Follow the simple tips mentioned above to reduce sodium intake from your daily diet.
