If you have high blood pressure, managing your salt intake is crucial. Salt, primarily composed of sodium chloride, significantly contributes to blood pressure levels. For individuals with hypertension, reducing salt consumption is a common recommendation. However, it's essential to strike a balance—too little sodium can lead to hypotension (low blood pressure). Therefore, while a low-sodium diet is advisable, it doesn't mean eliminating sodium entirely.

Datuk Dr Sanjiv Joshi (pix) a consultant cardiologist at Pantai Hospital Kuala Lumpur, emphasizes that adults with high blood pressure should aim for no more than 2,300 milligrams of sodium per day, with an ideal limit of 1,500 milligrams. Remarkably, cutting back by just 1,000 milligrams daily can lead to significant improvements in blood pressure and overall heart health.

Understanding salt and sodium equivalents
Table salt is approximately 40% sodium, making it crucial to understand sodium content to manage your intake effectively. Here are some common measurements:
  • 1/4 teaspoon salt = 575 mg sodium
  • 1/2 teaspoon salt = 1,150 mg sodium
  • 3/4 teaspoon salt = 1,725 mg sodium
  • 1 teaspoon salt = 2,300 mg sodium

Sneaky sodium sources
Sodium can often hide in unexpected places. To manage your intake, always check nutrition labels and opt for lower-sodium options. Some common culprits include:
  • Burgers
  • Deli meats and sandwiches
  • Egg dishes and omelets
  • Mixed pasta dishes
  • Pizza
  • Poultry
  • Savory snacks (chips, crackers, popcorn)
  • Soups

Smart shopping and cooking tips
Here are practical strategies to reduce sodium intake:
  • Shop smart, cook smart: Choose lower-sodium foods or low-sodium versions of your favorites. Your taste buds may need time to adjust, but many delicious low-sodium options are available.
  • Read labels: When buying prepared and packaged foods, look for terms like “soda,” “sodium,” or the symbol “Na.” Many products now advertise “low salt” or “low sodium.”
  • Increase fruits and vegetables: Opt for no-salt-added canned or frozen versions and avoid those with added sauces.
  • Select unsalted options: Choose unsalted nuts, seeds, dried beans, peas, and lentils.
  • Broths and soups: Use unsalted or low-sodium fat-free broths or soups.
  • Cooking practices: Avoid adding salt during cooking, and remove the salt shaker from your table. Try salt substitutes, which are affordable and safe for most people except those with kidney issues.
  • Flavor with spices and herbs: Enhance food flavor naturally without relying on salt.

Dining out: Restaurant meals often contain high sodium. To mitigate this:
  • Familiarize yourself with low-sodium options on the menu.
  • Specify your preferences when ordering.
  • Request dishes to be prepared without salt.
  • Use black pepper instead of salt and opt for fresh lemon juice for seasoning.

​Managing salt intake is vital for anyone with high blood pressure. By understanding sodium's role and implementing simple strategies, you can effectively control your blood pressure while enjoying a flavorful diet. Remember, it's not about eliminating salt entirely but finding the right balance for your health.
