Walk into an Indian kitchen and you are likely to find more than one kind of cooking fat. Mustard oil may flavour a traditional sabzi, coconut oil may be a staple in some regions, while ghee adds richness to dal, rotis and festive meals. With so many choices available, deciding which one is healthiest can be confusing.The World Health Organization (WHO), the American Heart Association and research published in peer-reviewed journals emphasise the importance of choosing fats carefully and limiting saturated and trans fat intake. Evidence suggests that the type of fat, the quantity consumed and the overall dietary pattern all influence health. These guidelines provide a useful framework for understanding the benefits and limitations of different cooking oils commonly used in Indian households. Eight cooking oils and fats, and what to know about them.
Coconut oil: A traditional choice that needs moderation
Coconut oil contains lauric acid, a saturated fatty acid, and medium-chain fatty acids. Some components can be digested and absorbed differently from longer-chain fats, but that does not automatically make coconut oil heart-protective. Because coconut oil is high in saturated fat, consuming it frequently or in large amounts can raise LDL, commonly called bad cholesterol. The doctor recommends limiting saturated fat and replacing it with unsaturated fats where possible. Coconut oil can be used for its flavour, but it should not be treated as a health supplement or a reason to eat more deep-fried food.
Refined vegetable oils: Not all are unhealthy
Sunflower, soybean, cottonseed, groundnut and palm oils are often grouped together in discussions about refined oils. Refining can reduce some naturally occurring compounds, such as certain antioxidants, but it does not mean that all refined oils lose their fats and vitamins or become inherently harmful. Their fatty acid profiles differ considerably. Sunflower and soybean oils, for example, provide unsaturated fats, and soybean oil also supplies some omega-3 alpha-linolenic acid. Omega-6 fats are essential nutrients, and ordinary consumption of omega-6-rich oils has not been shown to cause inflammation simply because of their omega-6 content. The more useful considerations are portion size, the oil’s suitability for the cooking temperature, and avoiding repeated reuse of oil for frying.
Mustard oil: A familiar option in Indian cooking
Mustard oil is valued for its distinctive flavour and is widely used in several Indian regional cuisines. It contains unsaturated fats, including monounsaturated and polyunsaturated fatty acids, as well as erucic acid. Traditional or kachchi ghani mustard oil is produced through a pressing process and generally retains its characteristic flavour. However, cold pressing does not automatically establish that an oil is the healthiest choice for everyone. Mustard oil’s erucic acid content is an important consideration, and claims that it prevents heart disease should not be made without strong evidence. Consumers should choose food-grade oil that complies with applicable safety standards.
Groundnut oil: Useful for everyday cooking
Groundnut, or peanut, oil contains substantial amounts of monounsaturated fat and vitamin E. Its relatively mild flavour makes it suitable for a variety of dishes, depending on the type of oil and its smoke point. Some groundnut oils retain more naturally occurring compounds than others, depending on processing. Still, claims that groundnut oil directly prevents heart disease or that kachchi ghani oil is always superior need to be treated cautiously. It can be one option in a varied cooking routine, provided it is used in reasonable quantities.
Ghee: Best enjoyed in measured amounts
Ghee is deeply rooted in Indian food traditions and contributes flavour to everyday meals. It also contains fat-soluble vitamins, although the amounts vary and should not make it the main source of these nutrients. Ghee is high in saturated fat. Using a small amount for taste is different from relying on it as the primary cooking fat. For people concerned about cholesterol or cardiovascular risk, replacing some saturated fat with unsaturated vegetable oils is consistent with WHO guidance.
Vanaspati ghee: Check the label carefully
Vanaspati, often associated with products such as Dalda, is a vegetable-fat product used in some commercial and household cooking. Historically, partially hydrogenated oils used in vanaspati have been an important source of industrial trans fats. Industrial trans fats increase cardiovascular risk and should be avoided. Not every product’s formulation is identical, so consumers should check labels and applicable food standards rather than assume all products contain the same amount. The WHO recommends keeping trans fat intake below 1% of total daily energy, with industrially produced trans fats avoided as far as possible.
Sesame oil and Olive oil
Sesame oil is commonly used in tempering, chutneys and regional dishes. It contains unsaturated fats and naturally occurring compounds, including sesame lignans, which have antioxidant properties. Its nutritional profile makes it a useful cooking option, but the presence of antioxidants does not mean that unlimited consumption is beneficial. As with other oils, the amount used and the overall balance of the diet matter.Olive oil, particularly extra-virgin olive oil, is rich in monounsaturated fat and contains other naturally occurring compounds. It can be included in Indian cooking if its taste suits the dish and the household budget. Different varieties are suitable for different uses. Extra-virgin olive oil works well in dressings and many everyday cooking applications, while the choice for high-heat cooking should take the oil’s properties into account.
The bigger lesson: Balance matters more than one oil
The most practical takeaway is that no single oil or ghee needs to be treated as a miracle food. Households can choose oils according to taste, affordability, availability and cooking needs, while keeping total fat consumption in check. Rotating oils may add variety, but rotation itself is not a guarantee of better health. Dietary fat is essential for energy, cell function and the absorption of vitamins. The goal is not to eliminate fat but to favour unsaturated fats over excessive saturated and trans fats. The cancer surgeon Dr Jayesh Sharma recommends limiting saturated fat and trans fat.A balanced Indian diet should also include vegetables, fruits, pulses, whole grains and adequate protein. Cooking at home more often can help people manage the amount of oil, salt and sugar they consume, while frequent deep-fried and highly processed foods are best limited. Ultimately, healthier eating is not about finding one perfect bottle of oil. It is about using fats in sensible quantities, choosing appropriate products and building meals around a varied, balanced diet.
