Is Your Cooking Oil Making You Sick? Cardiologist Reveals The Best And Worst Oils For Heart Health
Introduction Your choice of cooking oil could be silently affecting your cholesterol, blood pressure, and overall heart health. Many Indian households rely on refined oils for frying and daily cooking, but not all oils are created equal. Cardiologists warn that the wrong oil can raise bad cholesterol (LDL), clog arteries, and increase the risk of heart disease. On the other hand, heart-friendly oils—when used in moderation—can help maintain healthy cholesterol levels and support better cardiovascular function. Let’s understand which oils are healthy, which ones to avoid, and how to make the best choice for your family’s heart health. 1. Understanding How Cooking Oils Affect Your Heart Cooking oils are made up of fats—mainly saturated, unsaturated, and trans fats. Saturated fats (found in ghee, butter, coconut oil) can raise bad cholesterol if overused. Unsaturated fats (found in olive oil, mustard oil, groundnut oil) help improve good cholesterol (HDL). Trans fats (often in vanaspati or hydrogenated oils) are the worst—they increase LDL and lower HDL. Cardiologist advice: Always choose oils with a higher percentage of unsaturated fats and avoid refined or hydrogenated oils. 2. The Best Cooking Oils for Heart Health (According to Cardiologists) a. Mustard Oil Rich in monounsaturated and polyunsaturated fats Contains omega-3 fatty acids Helps reduce cholesterol and improve blood circulation Ideal for Indian cooking styles—sautéing, curries, and stir-frying b. Olive Oil Excellent for salad dressings or light cooking Reduces LDL and inflammation Best used raw or at low temperatures c. Groundnut Oil (Peanut Oil) High in monounsaturated fat Good for deep frying due to high smoke point May help lower LDL when used moderately d. Rice Bran Oil Contains oryzanol, which helps lower cholesterol Neutral taste; suitable for Indian gravies and frying e. Flaxseed Oil High in omega-3 fatty acids Improves blood pressure control Not for frying—best for drizzling or salad dressing READ ALSO: One Long Walk Vs.

Refined Vegetable Oils Over-processed with chemicals Lose natural nutrients and antioxidants Often contain high trans fat content b. Vanaspati or Dalda Hydrogenated oil loaded with trans fats Directly linked to high cholesterol and heart disease c. Palm Oil Common in packaged and fried foods High in saturated fats that raise LDL levels d. Reused Cooking Oil Repeated heating creates harmful compounds Increases oxidative stress and raises heart risk 4. Cooking Oils and Cholesterol: What the Data Says Studies show that switching from saturated to unsaturated oils can reduce LDL cholesterol by up to 10–15%. Using a mix of oils (like mustard plus rice bran or olive plus sunflower) can provide a balance of fatty acids and antioxidants. Cardiologist tip: Instead of using one oil throughout the year, rotate between two to three heart-friendly oils. 5. How Much Oil Is Safe Per Day? According to the Indian Council of Medical Research (ICMR): An adult should not consume more than 20–25 grams (4–5 teaspoons) of oil per day. Limit fried and processed foods. Pair oils with a diet rich in fruits, vegetables, whole grains, and lean proteins. 6. Lifestyle Tips to Protect Your Heart Use less oil: Switch to non-stick pans and air-frying. Check labels: Avoid “hydrogenated” or “partially hydrogenated” oils. Manage weight: Even healthy oils add calories. Monitor cholesterol and blood pressure regularly. Avoid fast foods: They use poor-quality oils that harm your arteries. 7.
