Ghee vs Refined Oil vs Cold-Pressed Oil: Which Is Actually Healthiest for Indian Cooking?

The cooking oil aisle has become one of the most confusing places in Indian grocery shopping. Ten years ago, refined vegetable oil was marketed as the modern, heart-healthy replacement for traditional ghee and cold-pressed oils. Then the research on trans fats and seed oil oxidation began emerging, and the narrative started reversing. Now refined vegetable oil is increasingly being questioned, ghee is being rehabilitated, and cold-pressed traditional oils are being rediscovered — while most families continue buying whatever is cheapest or most familiar, largely unsure what to believe.

This guide attempts to cut through the noise with a clear, evidence-referenced comparison of what these three oil categories actually do in the body, how they behave at cooking temperatures, and what the practical recommendation for Indian cooking is — given that Indian cooking methods include high-heat tadka, deep frying, slow-cooked curries, and raw additions to food.

The basics: what makes a cooking fat healthy or harmful

Before comparing specific oils, three concepts matter:

Fatty acid composition. All fats are composed of fatty acids — saturated, monounsaturated (MUFA), or polyunsaturated (PUFA). Saturated fats are structurally stable at high temperatures. MUFAs are stable at moderate temperatures. PUFAs — particularly omega-6 PUFAs — are structurally unstable and prone to oxidation when heated. The more polyunsaturated a fat is, the more it degrades when cooked.

Smoke point. The temperature at which a fat begins to smoke and break down into harmful compounds including aldehydes and acrolein. Cooking above an oil’s smoke point creates a cascade of chemical reactions that produce compounds ranging from irritating to genuinely carcinogenic with repeated exposure. Indian cooking methods — particularly deep frying and high-heat tadka — often exceed the smoke points of refined seed oils, which is a meaningful health concern.

Processing and what it removes. Refining strips oils of their natural antioxidants, Vitamin E, polyphenols and plant sterols — the very compounds that protect fats from oxidative damage in the body. A refined oil without these protective compounds behaves quite differently in biological systems than the whole food it was extracted from.

Ghee — the rehabilitated traditional fat

Ghee is clarified butter — made by simmering butter until the water evaporates and the milk solids separate, leaving pure butterfat. The clarification process removes milk proteins and sugars, which also makes ghee suitable for most lactose-intolerant individuals and longer-lasting at room temperature without refrigeration.

What ghee contains

Ghee is approximately 62% saturated fat, 28% monounsaturated fat, and 4% polyunsaturated fat — a composition that makes it among the most stable fats for cooking. Its smoke point is approximately 250°C — significantly higher than most refined vegetable oils — meaning it remains chemically stable even at Indian high-heat cooking temperatures.

Beyond basic fatty acids, grass-fed ghee (made from the milk of cows that graze rather than are grain-fed) contains meaningful amounts of:

• Butyrate: A short-chain fatty acid that is the primary fuel for the cells lining the colon, has anti-inflammatory properties in the gut, and supports gut barrier integrity. Butyrate from dietary ghee is absorbed and used by colonocytes within hours of consumption.
• CLA (Conjugated Linoleic Acid): Documented anti-inflammatory and potentially anticancer properties in animal studies. Higher in grass-fed dairy products.
• Fat-soluble Vitamins A, D, E and K2: K2 in particular is a nutrient commonly deficient in modern diets — it directs calcium to bones rather than arteries and is found almost exclusively in fermented foods and grass-fed dairy fat.

The cardiovascular question on ghee

The historical concern about ghee was its saturated fat content and its hypothetical effect on LDL cholesterol and cardiovascular disease. This concern has been significantly revised by newer research. The relationship between dietary saturated fat and cardiovascular disease is now understood to be far more complex and context-dependent than the simple “saturated fat raises cholesterol raises heart disease” model that dominated clinical advice for decades.

Specifically, a 2020 meta-analysis in the British Medical Journal found no significant association between dairy fat consumption and cardiovascular disease mortality. The saturated fats in dairy (particularly short and medium-chain saturated fatty acids like butyrate and lauric acid) behave differently in the body than the long-chain saturated fats in processed meat and partially hydrogenated oils.

The Ayurvedic tradition has recommended ghee as a digestive and metabolic enhancer for millennia — and the mechanism is now partially understood: butyrate from ghee feeds beneficial gut bacteria, improves insulin sensitivity, and reduces intestinal inflammation. These are anti-diabetic and cardiovascular-protective effects in the Indian metabolic disease context.

Practical recommendation: 1–2 teaspoons of ghee per meal, used for tadka and finishing dishes, is within a health-supporting range for most people. It is not a fat to eat by the spoonful, but used traditionally in Indian cooking portions, the evidence does not support avoiding it.

Refined vegetable oil — the case against the default choice

Refined vegetable oils — the category includes refined sunflower oil, soybean oil, cottonseed oil, palmolein, and their blends sold as “vegetable oil” or “cooking oil” across India — have dominated the Indian cooking oil market since the 1980s, when they were promoted as modern, heart-healthy alternatives to traditional fats.

The refining process and what it does

To make refined vegetable oil shelf-stable and odourless, seeds are typically solvent-extracted (using hexane) and then subjected to degumming, bleaching, and deodorisation at high temperatures (240–270°C). This process achieves its goals but with meaningful trade-offs:

• Natural antioxidants (Vitamin E, polyphenols) are largely destroyed or removed, leaving the oil with significantly reduced resistance to oxidation
• Trans fatty acids (partially hydrogenated) may form during high-temperature deodorisation
• Solvent residues (hexane) may remain in trace amounts in the final product
• The natural plant sterols, waxes and phytonutrients of the original seed are eliminated

The oxidation problem with high-PUFA refined oils

Refined sunflower oil, soybean oil and corn oil are all high in omega-6 polyunsaturated fatty acids (linoleic acid). These PUFAs are structurally fragile and oxidise readily — especially at high heat. When oxidised omega-6 fats are consumed, they contribute to systemic oxidative stress and inflammation.

This is particularly relevant in Indian cooking, where the same oil is often reused for multiple fryings. Each reheating cycle increases the concentration of oxidised lipid products — aldehydes and polymers that have documented toxicity in laboratory studies. A 2015 study from De Montfort University found that heating sunflower oil to common cooking temperatures produced levels of toxic aldehydes 200 times higher than WHO safe limits after extended cooking.

The irony of the last 40 years of Indian cooking oil advice is increasingly clear: the traditional fats (ghee, cold-pressed mustard oil, cold-pressed sesame oil) that were replaced by refined seed oils for health reasons may have been significantly less harmful than what replaced them — at least for the high-heat cooking applications central to Indian cuisine.

Cold-pressed traditional oils — the overlooked middle ground

Cold-pressed oils — extracted without heat through mechanical pressing — retain the natural antioxidants, polyphenols, Vitamin E and plant sterols of the source material. They are not solvent-extracted, not bleached, not deodorised. The resulting oil is more nutritionally complete, more oxidation-resistant due to its natural antioxidant content, and better-tasting.

Best cold-pressed oils for Indian cooking

Cold-pressed mustard oil (kachi ghani): The traditional cooking oil of North India. High in MUFA (approximately 60%), reasonable smoke point (250°C), rich in allyl isothiocyanate (natural antimicrobial) and omega-3 fatty acids at a favourable ratio. For high-heat North Indian cooking — tadka, parathas, sabzi — kachi ghani mustard oil is arguably the most appropriate traditional choice. Note: mustard oil is approved for cooking use in India but not as a food oil in the EU and US due to erucic acid content — the research on erucic acid at normal dietary levels is more complex than the regulatory position suggests.

Cold-pressed sesame oil (til oil): High in MUFAs and the antioxidant lignan sesamol. Sesamol is one of the most heat-stable natural antioxidants known — it prevents oil oxidation even at relatively high temperatures. Traditional in South Indian cooking and in Ayurvedic oil preparations. Moderate smoke point (180–210°C) — better for medium-heat cooking and tadka than deep frying.

Cold-pressed groundnut (peanut) oil: Traditional cooking oil across many Indian states. High MUFA content, moderate smoke point (160–230°C depending on refinement), good stability. The cold-pressed version retains natural Vitamin E and resveratrol — compounds essentially absent from refined peanut oil.

Cold-pressed coconut oil: Best for lower-medium heat cooking and raw applications. Not ideal for the high heat of Indian cooking due to its tendency to impart strong flavour and its unsuitability for certain applications — but valuable for specific preparations and all non-cooking uses.

The practical recommendation for Indian households

Rather than a single oil for all purposes, a two-oil kitchen approach works best for Indian cooking:

• For high-heat cooking (deep frying, high-heat tadka): Ghee or cold-pressed mustard oil / groundnut oil. These are the most stable fats at Indian cooking temperatures. If budget is a concern, even small amounts of ghee used for final tadka and finishing improves both flavour and the fat quality of the meal significantly.
• For medium-heat cooking and everyday sabzi: Cold-pressed sesame oil or cold-pressed groundnut oil.
• For raw use (salad dressings, chutneys, adding to cooked food): Cold-pressed sesame, mustard or flaxseed oil — these should not be heated.

If budget allows only one change: replace refined sunflower oil with kachi ghani mustard oil for North Indian households, or cold-pressed sesame oil for South Indian households. Both are available at most local grocery stores at a modest premium over refined oil — and both are significantly more stable at cooking temperatures and more nutritionally intact.

Frequently asked questions

Is ghee suitable for people with high cholesterol?

Current evidence does not support avoiding ghee specifically for people with elevated LDL cholesterol. Ghee’s short and medium-chain saturated fats have a different metabolic effect than the long-chain saturated fats that correlate most strongly with adverse cholesterol outcomes. However, this is individual — consult your doctor if you have cardiovascular disease or significantly elevated cholesterol.

Is refined oil safe if used in small amounts?

Yes — the health concerns with refined seed oils relate primarily to high-heat use and excessive quantities. Small amounts used at low heat (added to cold dishes, used at minimal quantities in cooking) pose significantly less risk than large quantities at high heat repeatedly.

Which oil is best for heart health specifically?

The oils with the strongest cardiovascular evidence are extra virgin olive oil (predominantly MUFA, extensively studied) and cold-pressed mustard oil (also high MUFA, and specifically studied in Indian population data). A 2001 Indian study found that patients who cooked with mustard oil had significantly lower rates of heart attack recurrence than those using refined sunflower oil.

The kitchen had the right answer already

The traditional Indian kitchen — ghee for finishing and high-heat cooking, cold-pressed regional oil as the main cooking medium, minimal frying — was a more nutritionally sophisticated fat management system than it was given credit for. The shift toward refined seed oils as a health improvement turned out, on the evidence now available, to be a downgrade rather than an upgrade.
