Sarson Ka Tel: 9 Science-Backed Health Benefits of Mustard Oil
From heart health to antibacterial properties, sarson ka tel (mustard oil) is one of the most nutritionally complete cooking oils in the Indian kitchen. Here is what the science says.
The Nutritional Profile of Cold Press Mustard Oil
Before the benefits, the numbers. Per 100ml of cold press (kachi ghani) mustard oil:
| Nutrient | Amount |
|---|---|
| Total fat | 100g |
| Saturated fat | ~7g (very low) |
| Monounsaturated fat (MUFA) | ~60g |
| Polyunsaturated fat (PUFA) | ~21g |
| Omega-3 (ALA) | ~6–14g |
| Omega-6 (LA) | ~12–15g |
| Omega-3 : Omega-6 ratio | ~1:2 |
| Vitamin E (tocopherols) | ~17mg |
| Erucic acid | ~42g |
The omega-3 to omega-6 ratio of approximately 1:2 is one of the most balanced of any cooking oil — far better than sunflower oil (1:40) or refined soya oil (1:7). This ratio matters enormously for inflammation control in the body.
1. Supports Heart Health
The high MUFA content in mustard oil — primarily oleic acid — is associated with reduced LDL ("bad") cholesterol and maintained or improved HDL ("good") cholesterol levels. Studies conducted in Indian populations have found that households using mustard oil as their primary cooking fat had lower rates of ischaemic heart disease compared to those using vanaspati (hydrogenated vegetable fat) or refined oils.
The omega-3 fatty acids (alpha-linolenic acid, or ALA) in mustard oil also contribute to cardiovascular health by reducing triglyceride levels and supporting healthy blood pressure.
Key point: The fat composition of cold press mustard oil is closer to the Mediterranean diet's olive oil than to most other South Asian cooking oils.
2. Powerful Anti-Inflammatory Properties
Mustard oil contains allyl isothiocyanate (AITC) — the compound responsible for its characteristic pungency. AITC has been shown in laboratory studies to inhibit inflammatory pathways, including the COX-2 enzyme pathway that is targeted by common anti-inflammatory drugs.
This is why traditional Indian medicine (Ayurveda) has long used mustard oil for massage in conditions involving joint pain and muscle stiffness. The anti-inflammatory effect works both topically and, to a lesser extent, when consumed as part of a regular diet.
Cold press extraction is essential here — heat processing destroys a significant portion of AITC before the oil ever reaches your kitchen.
3. Natural Antibacterial and Antifungal Agent
AITC is also a potent natural antimicrobial. Research has demonstrated its effectiveness against a range of bacteria including E. coli, Staphylococcus aureus, and Listeria monocytogenes, as well as several common food-spoilage fungi.
This is the scientific basis for something Indian grandmothers have known for generations: mustard oil preserves pickles (achar) without refrigeration. The oil's natural antimicrobial properties inhibit the growth of spoilage organisms, allowing mango, lemon, and mixed vegetable achars to last for months at room temperature.
Refined mustard oil — stripped of its AITC during heat processing — does not offer this benefit.
4. Rich in Vitamin E — A Natural Antioxidant
Cold press mustard oil contains approximately 17mg of Vitamin E per 100ml, primarily in the form of tocopherols. Vitamin E is a fat-soluble antioxidant that:
- Protects cell membranes from oxidative damage
- Supports immune function
- Plays a role in skin health and wound healing
- May reduce the risk of age-related cognitive decline
Because Vitamin E is heat-sensitive, cold press extraction preserves significantly more of it than refining. When you cook with kachi ghani mustard oil, you are getting a meaningful dietary source of this antioxidant with every meal.
5. Stimulates Digestion and Appetite
Mustard oil has been used as a digestive stimulant in traditional medicine across South Asia. The pungent compounds in the oil stimulate the production of gastric juices and bile, which aids in the digestion of fats and proteins.
This is why a small amount of raw mustard oil drizzled over dal or rice — common in Bengali cuisine — is not just a flavour choice. It is a functional one. The oil primes the digestive system before a meal.
For people with sluggish digestion or reduced appetite, incorporating cold press mustard oil into daily cooking can provide a gentle, food-based digestive stimulus without the side effects of pharmaceutical interventions.
6. Supports Healthy Skin and Hair
The same properties that make mustard oil valuable in cooking make it effective topically:
For skin: The high MUFA content and Vitamin E make mustard oil an effective moisturiser for dry skin. Its antibacterial properties help with minor skin infections and acne. In North Indian tradition, mustard oil massage (maalish) for newborns and infants is a centuries-old practice — recent research has found it may support healthy weight gain and skin barrier function in neonates.
For hair: Mustard oil is rich in beta-sitosterol, a plant sterol associated with reduced hair loss. Regular scalp massage with warm mustard oil improves blood circulation to hair follicles, reduces dandruff (thanks to its antifungal properties), and conditions the hair shaft.
The key is using cold press oil — the heat processing in refined oil degrades the fatty acids and removes the beneficial compounds that make topical application effective.
7. May Help Regulate Blood Sugar
Emerging research suggests that the omega-3 fatty acids and MUFA in mustard oil may support insulin sensitivity and help moderate post-meal blood glucose spikes. A 2016 study published in the Journal of Preventive Cardiology found that mustard oil consumption was associated with better glycaemic control compared to sunflower oil in patients with type 2 diabetes.
While mustard oil is not a treatment for diabetes, replacing refined oils with cold press mustard oil as part of a balanced diet is a sensible dietary choice for people managing blood sugar.
8. Warming Properties — Particularly Valuable in North Indian Winters
Traditional Indian medicine classifies mustard oil as a "warming" food — one that generates internal heat and improves circulation. This is not merely metaphorical. The AITC in mustard oil is a vasodilator: it causes blood vessels to dilate, improving peripheral circulation.
In the cold winters of Haryana, Punjab, Delhi, and Gurgaon, this property is practically valuable. Cooking with mustard oil, and using it for body massage before bathing, helps maintain warmth and circulation during the coldest months. It is no coincidence that mustard oil consumption is highest in the northern states where winters are most severe.
9. Zero Trans Fats — Unlike Vanaspati and Many Refined Oils
Cold press mustard oil contains no trans fats. This alone sets it apart from vanaspati (partially hydrogenated vegetable fat), which is still widely used in Indian commercial kitchens and street food, and which is associated with significantly elevated cardiovascular risk.
Even many "refined" vegetable oils undergo partial hydrogenation during processing, introducing small amounts of trans fats. Cold press extraction involves no hydrogenation — the oil goes from seed to bottle without any chemical transformation of its fatty acid structure.
A Note on Erucic Acid
You may have read concerns about erucic acid in mustard oil. This requires context.
Mustard oil contains approximately 42% erucic acid, a long-chain fatty acid. High doses of erucic acid in animal studies (primarily rats) were associated with cardiac lipidosis. Based on these studies, the FDA banned mustard oil for cooking use in the United States in 1956.
However, subsequent research has found that:
- Rats metabolise erucic acid differently from humans — the cardiac effects observed in rats have not been replicated in human studies
- Populations in India, Bangladesh, and Nepal have consumed mustard oil as their primary cooking fat for millennia with no documented epidemic of erucic acid-related cardiac disease
- The WHO's Joint Expert Committee on Food Additives has set a tolerable daily intake for erucic acid that is well within the range consumed by regular mustard oil users in India
The Indian Council of Medical Research (ICMR) and FSSAI both permit mustard oil for cooking. The scientific consensus among researchers studying Indian dietary patterns is that mustard oil, consumed in normal cooking quantities, does not pose a cardiac risk from erucic acid.
Cold Press vs. Refined: Why the Extraction Method Matters
All of the benefits described above apply specifically to cold press (kachi ghani) mustard oil. Refined mustard oil is a different product:
- Heat refining (above 200°C) destroys AITC, Vitamin E, and degrades omega-3 fatty acids
- Solvent extraction (using hexane) removes beneficial phytochemicals along with the oil
- Bleaching and deodorising strip the oil of its natural colour, aroma, and remaining micronutrients
What remains after refining is primarily a fat with a neutral flavour — useful for high-heat frying, but nutritionally impoverished compared to the original seed.
If you are cooking with mustard oil for its health benefits, the extraction method is not a minor detail. It is the whole point.
How to Incorporate Sarson Ka Tel into Your Daily Diet
Tadka and tempering: Use cold press mustard oil as your base fat for dal, sabzi, and rice dishes. Heat until it just begins to smoke, let it settle for 30 seconds, then add your spices.
Raw drizzle: A teaspoon of raw mustard oil over dal, khichdi, or steamed rice is a traditional Bengali practice that delivers the full nutritional profile without heat degradation.
Achar and preserves: Use mustard oil as the base for homemade pickles. Its antimicrobial properties are essential for long shelf life without refrigeration.
Marinades: Mustard oil is an excellent marinade base for fish, chicken, and paneer. Its pungency mellows significantly with cooking, leaving a distinctive depth of flavour.
Salad dressings: Raw mustard oil in a dressing — with lemon juice, black salt, and cumin — is a nutritionally dense alternative to olive oil for Indian-style salads.

FAQ
What are the health benefits of sarson ka tel (mustard oil)? Cold press mustard oil has nine key health benefits: it supports heart health through its high MUFA and omega-3 content, reduces inflammation via allyl isothiocyanate, has natural antibacterial and antifungal properties, provides vitamin E as an antioxidant, stimulates digestion, supports healthy skin and hair, may help regulate blood sugar, has warming properties that improve circulation in winter, and contains zero trans fats unlike vanaspati or many refined oils.
Is sarson ka tel good for the heart? Yes — cold press mustard oil has a fat composition that is genuinely heart-friendly. It is high in monounsaturated fat (approximately 60% oleic acid, the same fat in olive oil), rich in omega-3 fatty acids (ALA) which reduce cardiovascular inflammation, and low in saturated fat (approximately 7%). Studies on traditional North Indian diets where mustard oil is the primary cooking fat have found lower rates of ischaemic heart disease compared to populations using vanaspati or refined oils.
Does mustard oil contain omega-3 fatty acids? Yes — cold press mustard oil contains approximately 6–14g of alpha-linolenic acid (ALA) per 100ml, making it one of the best plant sources of omega-3 in the Indian diet. The omega-3 to omega-6 ratio of approximately 1:2 is one of the most balanced of any cooking oil available in India. Critically, this omega-3 content is only preserved in cold pressed oil — refined mustard oil loses up to 80% of its ALA during high-heat extraction.
Is erucic acid in mustard oil dangerous? The scientific consensus for Indian dietary patterns is that mustard oil consumed in normal cooking quantities does not pose a cardiac risk from erucic acid. While high-dose animal studies (primarily in rats) raised concerns, subsequent research found that rats metabolise erucic acid differently from humans. Populations in India, Bangladesh, and Nepal have consumed mustard oil as their primary cooking fat for millennia without documented erucic acid-related cardiac disease. FSSAI and ICMR both permit mustard oil for cooking in India.
What is the difference between cold press and refined mustard oil for health? Cold press mustard oil retains all its natural nutrients — omega-3 fatty acids, vitamin E, allyl isothiocyanate, and glucosinolates. Refined mustard oil loses most of these during high-heat extraction (200–270°C) and chemical refining. If you are cooking with mustard oil for its health benefits, the extraction method is not a minor detail — it determines whether the beneficial compounds are present at all.
