Before You Call Mustard Oil “Healthy,” Look at These 4 Numbers

Four Numbers That Make Mustard Oil Interesting

Mustard oil has been part of Indian cooking for generations, but its nutritional profile makes it particularly interesting to examine.

Here are four numbers worth knowing.

1. ~6% ALA omega-3
Commonly cited mustard-oil composition data place alpha-linolenic acid around 6%. ALA is an omega-3 fatty acid.

2. ~15% linoleic acid
This is an omega-6 fatty acid. Using these representative values gives an omega-6 to omega-3 ratio of approximately 2.5:1.

3. ~250°C smoke point
Mustard oil is commonly reported to have a smoke point around 250°C (482°F). This makes it relevant to high-temperature cooking, although smoke point alone isn't a measure of overall healthfulness.

4. Erucic acid
Conventional mustard oil can contain substantial erucic acid. The amount varies according to mustard variety and other factors.

These numbers show why cooking-oil comparisons need more nuance than simply calling one oil “healthy” and another “unhealthy.”

The complete mustard oil comparison looks at extraction, fatty acids, cooking performance, erucic acid and cardiovascular considerations together.
