Mustard oil—commonly known as sarson ka tel—has been a staple cooking medium in Indian households for centuries. From Bengali fish curries to North Indian pickles, its strong aroma and sharp flavor make it unique. But beyond taste, mustard oil has a distinct nutritional profile that many people misunderstand.

This detailed guide explores everything you need to know about mustard oil nutrition—its calories, fat composition, vitamins, and how it fits into a healthy diet.

1. What Is Mustard Oil?

Mustard oil is extracted from mustard seeds (black, brown, or white varieties) through cold pressing or refining processes. It is widely used in India, Bangladesh, and parts of Asia for cooking, frying, and pickling.

Nutritionally, mustard oil belongs to the category of pure fats, meaning:

• It contains no carbohydrates
• No protein
• Almost entirely composed of fats

This makes it an energy-dense food.

2. Mustard Oil Nutrition Facts (Per Tablespoon)

Here’s the standard nutritional breakdown of mustard oil per 1 tablespoon (about 14 grams):

• Calories: 124
• Total Fat: 14 g
• Carbohydrates: 0 g
• Protein: 0 g
• Sugar: 0 g
• Sodium: 0 mg 

👉 This shows that 100% of calories in mustard oil come from fat.

3. Mustard Oil Nutrition (Per 100 grams)

To better understand its density:

• Calories: ~884 kcal
• Fat: 100 g
• Protein: 0 g
• Carbohydrates: 0 g 

This is similar to all cooking oils—highly concentrated sources of energy.

4. Calories in Mustard Oil: Why It’s So High

Mustard oil is calorie-dense because fats provide:

• 9 calories per gram (more than double carbs or protein)

So even a small amount adds significant calories.

Example:

• 1 tablespoon = 124 calories
• 2 tablespoons = ~248 calories

👉 This is why portion control is essential.

5. Fat Composition of Mustard Oil

The real nutritional value of mustard oil lies in its fat profile, not just calories.

Types of Fat in Mustard Oil

1. Monounsaturated Fat (MUFA)

• Major component
• Heart-friendly fat
• Helps reduce bad cholesterol (LDL)

2. Polyunsaturated Fat (PUFA)

• Includes omega-3 and omega-6 fatty acids
• Supports brain and heart health

3. Saturated Fat

• Present in small amounts
• Needs to be consumed in moderation

Approximate Breakdown (per 100g):

• Monounsaturated fat: ~59%
• Polyunsaturated fat: ~21–30%
• Saturated fat: ~6–12% 

👉 This balance makes mustard oil nutritionally better than many saturated-fat-heavy oils.

6. Omega Fatty Acids in Mustard Oil

Mustard oil stands out because it contains a good balance of omega fats:

• Omega-3 fatty acids (ALA)
• Omega-6 fatty acids
• Omega-9 (oleic acid)

Why This Matters:

• Omega-3 → Anti-inflammatory
• Omega-6 → Essential for growth
• Omega-9 → Supports heart health

👉 The ratio of omega-3 to omega-6 in mustard oil is considered relatively balanced compared to many other vegetable oils.

7. Saturated vs Unsaturated Fat: What Makes Mustard Oil Healthy?

Unlike butter or ghee, mustard oil is rich in unsaturated fats, which are considered healthier.

Key Differences:

👉 This composition supports:

• Better cholesterol levels
• Reduced risk of heart disease
• Improved metabolic health

8. Vitamins in Mustard Oil

One common misconception is that mustard oil is rich in many vitamins. In reality:

Main Vitamin Present:

• Vitamin E (Tocopherol)
  • Acts as an antioxidant
  • Protects cells from damage
  • Supports skin and immunity

Mustard oil contains about:

• ~25 mg Vitamin E per 100g 

What About Other Vitamins?

According to standard nutrition data:

• No significant Vitamin A
• No Vitamin C
• No B vitamins 

👉 So mustard oil is not a major vitamin source, except for Vitamin E.

9. Minerals in Mustard Oil

Mustard oil contains negligible minerals:

• Calcium: 0
• Iron: 0
• Magnesium: 0
• Potassium: 0 

👉 This is because oil is a purified fat extracted from seeds, leaving most minerals behind.

10. Does Mustard Oil Contain Protein or Fiber?

No.

• Protein: 0 g
• Fiber: 0 g 

👉 Even though mustard seeds contain protein and fiber, the oil does not.

11. Cholesterol Content in Mustard Oil

• Cholesterol: 0

👉 Like all plant oils, mustard oil is naturally cholesterol-free.

12. Unique Compounds in Mustard Oil

Mustard oil also contains bioactive compounds like:

1. Allyl Isothiocyanate

• Responsible for pungent flavor
• Has antimicrobial properties

2. Erucic Acid

• A type of monounsaturated fat
• Present in varying amounts depending on oil quality

👉 These compounds make mustard oil different from neutral oils like sunflower or soybean oil.

13. Glycemic Index of Mustard Oil

• Glycemic Index (GI): 0

👉 It does not affect blood sugar levels directly.

This makes mustard oil suitable for:

• Diabetic diets
• Low-carb or keto diets

14. Mustard Oil vs Other Cooking Oils (Nutritional Comparison)

👉 Mustard oil stands out for its omega-3 content and balanced fat profile.

15. Health Implications of Mustard Oil Nutrition

Benefits Based on Nutritional Profile

1. Heart Health

• High MUFA helps reduce bad cholesterol

2. Anti-Inflammatory Effects

• Omega-3 fatty acids help reduce inflammation

3. Energy Source

• High calorie content provides instant energy

4. Skin & Hair Benefits

• Vitamin E acts as an antioxidant

Potential Concerns

1. High Calorie Density

• Easy to overconsume → weight gain

2. Erucic Acid Debate

• Excess intake may have risks (in very high amounts)

👉 Moderation is key.

16. Is Mustard Oil Healthy?

Yes—but with conditions.

Healthy When:

✔ Used in moderation
✔ Part of a balanced diet
✔ Combined with other oils

Not Ideal When:

❌ Used excessively
❌ Only fat source in diet

17. How Much Mustard Oil Should You Consume?

General guideline:

• 2–3 teaspoons per day per person (from all oils combined)

👉 Rotate oils for better nutrient diversity.

18. Cooking with Mustard Oil: Nutritional Impact

Heating Effects:

• Retains most fat composition
• Vitamin E may slightly reduce at high heat

Best Uses:

• Frying
• Pickling
• Tempering (tadka)

19. Cold-Pressed vs Refined Mustard Oil

Cold-Pressed (Kachi Ghani)

• Retains nutrients better
• Higher antioxidants

Refined

• Milder taste
• Slight nutrient loss

👉 For nutrition, cold-pressed is better.

20. Final Thoughts

Mustard oil is a high-calorie, fat-rich cooking oil with a strong nutritional advantage due to its balanced fatty acid profile.

Key Takeaways:

• 100% fat, zero carbs & protein
• Rich in MUFA and PUFA
• Contains Vitamin E
• Supports heart health
• Should be used in moderation

In Indian diets—especially in regions like Bengal—it remains one of the most nutritionally balanced traditional oils when used wisely.
