Excess salt consumption has long been linked to high blood pressure, but cardiologists now warn that the risks extend much deeper into heart health itself. According to Dr. Sameer Pagad, Director of Interventional Cardiology at Nanavati Max Super Speciality Hospital, Mumbai, a diet rich in sodium can damage the heart muscle, making it harder for the organ to pump blood efficiently.
The specialist explained that consuming too much sodium leads to thickening of the heart’s walls, a condition known as left ventricular hypertrophy. Over time, this reduces the heart’s pumping power and raises the risk of heart failure. Sodium also interferes with calcium levels in the heart’s cells, disturbing the contraction and relaxation process that keeps blood flowing smoothly.
How to Reverse the Effects of Excess Sodium?
Dr. Pagad highlighted that the damage caused by a high-salt diet can be managed with potassium-rich foods. Vegetables such as spinach, amaranth, fenugreek, bottle gourd, and pumpkin are recommended for vegetarians. Fruits like bananas, guava, papaya, oranges, mosambi, and pomegranate also help balance sodium’s harmful effects. Pulses including moong, masoor, chana, and rajma are excellent additions to a heart-healthy plate.
For hydration, adding a glass of tender coconut water daily can also aid in restoring mineral balance.
Non-vegetarians are encouraged to include omega-3-rich fish in their diet. Options such as sardines, mackerel (bangda), Indian salmon, and raavas are considered cardioprotective and anti-arrhythmic. One to two servings of fatty fish per week can significantly support heart function.
Dr. Pagad stressed the importance of relying on natural foods rather than supplements, while also urging individuals to seek personalized medical advice from a cardiologist or dietitian before making dietary changes.
How Much Salt is Safe?
Even small reductions in salt intake can make a noticeable difference. “Cutting down by just 1 gram of salt per day can lower blood pressure levels significantly,” Dr. Pagad advised. He recommends limiting daily sodium intake to around 2 grams to reduce the risk of hypertension, coronary heart disease, arrhythmia, stroke, and heart failure.
Maintaining a diet low in sodium while increasing potassium-rich foods can protect cardiovascular health and support long-term heart function.
