Is mustard oil good for cooking?

Question

I’ve been thinking of switching to healthier cooking oils, and someone suggested mustard oil as a traditional and healthy option. However, I’ve heard mixed opinions about whether mustard oil is good for cooking or not. Can someone explain its benefits and any potential drawbacks?

I’ve seen mustard oil being used in Indian households for deep-frying, sautéing, and even as a dressing for certain dishes. But I’ve also read that some countries restrict its use due to concerns about a compound called erucic acid. Does this mean mustard oil is unsafe for regular cooking, or is it only harmful if consumed in excess?

I’m particularly curious if mustard oil can help with digestion or improving immunity, as some sources claim. Is it better for high-heat cooking like frying, or should it only be used for low-heat methods?

Another question I have is whether the type of mustard oil matters. I’ve seen labels like “cold-pressed” or “kachi ghani” mustard oil—are these healthier than refined versions?

If anyone has been using mustard oil regularly in their cooking, I’d love to know about your experience. Did it make a difference to the flavor or health of your meals? Are there any precautions or tips for using mustard oil in cooking effectively?

Mustard Oil Benefits & Drawbacks:
Benefits: Mustard oil is rich in monounsaturated fats (healthy fats), and contains omega-3 fatty acids, vitamin E, and antioxidants that support heart health, digestion, and immunity.
Digestion & Immunity: Mustard oil can stimulate digestion and has anti-inflammatory properties that may boost immunity.
Concerns about Erucic Acid:
Erucic acid is found in mustard oil, but the levels in culinary mustard oil are generally considered safe for moderate consumption. However, some countries restrict it due to concerns over high consumption leading to heart issues in excessive amounts. As long as it's used in moderation, it's safe for regular cooking.
High-Heat Cooking:
Mustard oil has a high smoking point, making it suitable for frying and sautéing. It retains its properties well under heat, but avoid overheating to prevent nutrient loss or harmful compounds.
Cold-Pressed vs. Refined Mustard Oil:
Cold-pressed or kachi ghani mustard oil is healthier because it’s minimally processed, retaining more nutrients and antioxidants compared to refined versions.
Tips for Using Mustard Oil:
Use mustard oil moderately for sautéing, frying, or as a salad dressing.
Cold-pressed mustard oil is generally preferred for health benefits.
If you’re new to the flavor, start with small amounts, as mustard oil has a strong taste.
Personal Experience:
Many users find mustard oil adds a distinct, rich flavor to dishes, especially in Indian cooking. It’s effective for digestive health, but it's best to use it in moderation as part of a balanced diet.
