Every week, without fail, someone sits down in my clinic after a cardiac event or a worrying cholesterol report and says the same thing. The doctor told me to cut salt. So I stopped adding salt at the table. That is all I have done.
And I understand why. Salt and heart health have been linked so loudly and for so long that people genuinely believe it is the whole story. But after two decades of working with cardiac patients, people managing high cholesterol, and individuals trying to protect a heart that has already given them one warning, I can tell you clearly: sodium is one piece of a much larger picture.
The good news is that the full picture is not complicated. It is actually more about what you add to your diet than what you take away.
Yes, Salt Matters. But Here is the Real Problem with Sodium
Excess sodium causes the body to retain water, which increases blood volume, which puts more pressure on artery walls. That is the mechanism behind the salt and blood pressure connection, and it is real. Reducing sodium does help, particularly for people who are salt sensitive.
But here is where most people get it wrong. When I ask them to track their sodium for a week, the biggest sources are almost never the salt shaker. They are packaged snacks, pickles, papads, processed foods, ready to eat meals, instant soups, store bought sauces, and yes, those supposedly healthy multigrain biscuits. Visible salt is a small fraction of what most Indians consume in a day.
So by all means, ease up on the salt while cooking. But spend equal energy reading labels on packaged food and reducing your intake of processed items. That is where the real sodium reduction happens.
The Fat Conversation We Have Been Having Wrong
For decades, fat was the enemy. Low fat products flooded the market. People stopped eating eggs, avoided ghee, and switched to refined vegetable oils thinking they were doing their heart a favour. The science has since moved on considerably, and what we now understand is more nuanced.
Not all fats are the same. The fats that genuinely harm cardiovascular health are trans fats, found in vanaspati, dalda, commercially fried foods, and many packaged baked goods. These raise your bad cholesterol and lower your good cholesterol simultaneously, and they have no redeeming nutritional value whatsoever.
Saturated fats, present in red meat, full fat dairy, and coconut oil, are worth moderating but do not need to be eliminated completely in a balanced diet. Unsaturated fats, which come from nuts, seeds, avocado, mustard oil, and olive oil, actively support heart health.
And then there is ghee. I know this surprises people, but a small amount of pure desi ghee used in cooking is not the cardiac villain it was once made out to be. What is far more damaging is refined seed oil used at high heat repeatedly, which is what happens in most deep frying. The type of fat and how it is cooked matters enormously.
Omega 3s: The Fats Your Heart Actually Wants
If there is one nutritional intervention with the most consistent, strongest evidence for heart health, it is omega 3 fatty acids. These are the fats found in fatty fish like salmon, mackerel, sardines, rohu, and katla. They reduce triglycerides, lower inflammation, help regulate heart rhythm, and have been shown to reduce the risk of cardiovascular events in people who already have heart disease.
If you eat fish, aim for two to three servings of fatty fish per week. If you are vegetarian, your best sources of plant-based omega 3s are flaxseeds, chia seeds, walnuts, and hemp seeds. Add a tablespoon of ground flaxseed to your roti dough, your dal, or your curd. It is tasteless, effortless, and genuinely useful.
Walnuts deserve a special mention. A small handful, about 28 grams or roughly 7 whole walnuts, eaten daily has been associated in multiple large studies with improved cholesterol profiles and reduced cardiovascular risk. They are also one of the most practical snacks imaginable.
Fibre: The Unsung Hero of Heart Health
Soluble fibre is one of the most powerful dietary tools for lowering LDL cholesterol, and most people are not getting nearly enough of it. Soluble fibre works by binding to cholesterol in the digestive tract and removing it from the body before it can be absorbed. It is a remarkably direct mechanism, and the foods that provide it are entirely ordinary.
Oats are the most well studied source. A bowl of oats for breakfast every day can make a clinically meaningful reduction in LDL over time. But oats are not the only option. Barley, whole dals, rajma, chana, apples, pears, isabgol, and okra are all excellent sources of soluble fibre. Indian cuisine, when cooked traditionally with whole pulses and vegetables, is actually fibre rich by nature. The problem arises when we shift toward refined grains, fewer vegetables, and more processed food.
A simple goal: aim for at least two servings of whole pulses or legumes every day, and make sure half your grains are whole grains. That alone will transform your fibre intake.
The DASH Approach: Eating for Blood Pressure
The DASH diet, which stands for Dietary Approaches to Stop Hypertension, is one of the most thoroughly researched dietary patterns for cardiovascular health. It is not a fad. It is not restrictive in any dramatic way. It is essentially a framework that emphasizes what most of us already know works, just laid out with more clarity.
The DASH approach prioritizes fruits, vegetables, whole grains, low fat dairy, nuts and seeds, and lean protein. It limits red meat, added sugar, sodium, and saturated fat. What is notable is that it is not asking you to eat unusual or expensive foods. It is asking you to eat more of the simple, whole, traditional foods that most Indian households cooked with before convenience became the priority.
Translated into an Indian kitchen, a DASH aligned day might look like: oats or dalia with fruit and nuts for breakfast, a lunch of dal, sabzi, roti, and curd, a small snack of walnuts or roasted chana, and a dinner of fish or paneer with vegetables and a small portion of brown rice or millets. That is not a diet. That is simply good cooking.
What About Alcohol, Stress, and Sleep?
I always tell my patients that nutrition is powerful, but it does not work in isolation. Three non-food factors consistently undermine even the best eating habits when it comes to heart health.
Chronic stress raises cortisol, which raises blood pressure and promotes inflammation. Poor sleep disrupts the hormones that regulate blood pressure and increases the risk of metabolic issues that affect the heart. Alcohol, even in moderate amounts, adds calories, raises triglycerides, and can elevate blood pressure over time. These are not reasons for guilt. They are reasons to look at heart health as a whole person issue, not just a plate issue.
Feed Your Heart Like You Mean It
Cutting salt is a good starting point. But it is just the door. The room inside is far more interesting and far more impactful.
Eat more fish, walnuts, and flaxseeds. Build your meals around dal, sabzi, and whole grains. Use good oils wisely. Reduce packaged and processed food. Get your fibre from real food. Move after meals. Sleep well. Manage what stresses you.
None of this requires a special diet, an expensive supplement, or a complete overhaul of your kitchen. It requires consistent, small choices that add up over months and years into a genuinely protected heart.
Your heart has been working for you every single minute of your life without being asked. The least you can do is feed it well.
