In every kitchen, certain ingredients work quietly in the background to bring a burst of life to our food. Mustard is one of them. Whether it’s a smooth yellow spread on a sandwich, spicy brown paste in a marinade, or tiny seeds popping in hot oil, mustard has been brightening meals for thousands of years.

From ancient Rome to modern dining tables, mustard has found its place in both humble, home cooking and fine dining. Yet this pungent spice is more than just a common condiment, it is a storehouse of nutrients with surprising health benefits.

What is mustard?

Mustard comes from the seeds of plants belonging to the Brassica family, which also includes cabbage, cauliflower, and broccoli. The three most common types are:

  • White mustard (Sinapis alba) – The seeds of this plant are mild in flavor. With the help of  turmeric for color, they are used to produce yellow mustard. 
  • Brown mustard (Brassica juncea) – This multipurpose plant is also grown for its leafy greens. The medium to spicy seeds are often used in Indian cooking.
  • Black mustard (Brassica nigra) – Strong and pungent, these seeds are widely used in making pickles, and certain traditional remedies.

Mustard’s history goes back over 5,000 years. The ancient Romans were among the first to mix crushed mustard seeds with grape juice to make a sauce. In Ayurveda and other traditional systems of medicine, mustard seeds and oil were valued for aiding digestion, warming the body, and easing muscle pain.

Nutritional value

For the small amount of mustard we consume, we get a surprising supply of nutrients, including vitamins A, C, E, K, and B-complex, which are vital for immunity, skin health, supporting brain function, energy production, and bone strength.

It is also rich in minerals, healthy fats, and antioxidants that help protect the body’s cells from damage. Hence, even a teaspoon of mustard seeds in your cooking can improve the nutritional value of your meal.

Health benefits of mustard

1. Supports heart health

Mustard seeds are a source of omega-3 fatty acids, which are linked to maintaining healthy blood vessels and help manage cholesterol levels.

2. Aids digestion

Mustard stimulates the production of saliva and digestive juices, making it easier for the body to break down food. This is one reason many cuisines use mustard seeds in pickles and curries.

3. Anti-inflammatory properties

The selenium and magnesium in mustard seeds may help reduce inflammation. This could be one reason why mustard poultices were used in the past for joint pain and sore muscles.

4. May ease muscle discomfort

Some people use mustard externally or take small amounts during exercise cramps, although this folk remedy is not backed by scientific research.

5. Good for skin and hair

Food-grade mustard oil has traditionally been used (in moderation) to massage the scalp, promote hair health, and nourish the skin.

6. Supports respiratory health

In traditional remedies, mustard plasters and steam inhalations with mustard oil were used to relieve congestion and ease breathing during colds.

How to use mustard in cooking

Mustard is one of the most versatile flavorings you can keep in your kitchen. Here are some popular ways to enjoy it:

  • As a condiment: Spread yellow or Dijon mustard on sandwiches, wraps, and burgers. If you have time, make your own prepared mustard!
  • In salad dressings: Mix mustard with olive oil, lemon juice, and honey for a quick vinaigrette.
  • In Indian cooking: Temper mustard seeds in hot oil until they pop, then add vegetables, lentils, or curries.
  • In marinades: Combine mustard with herbs, garlic, and yogurt or vinegar to flavour meats, tofu, or vegetables.
  • In pickles: Add whole mustard seeds to the pickling liquid for mild heat and depth of flavour.
  • As a glaze: Brush mustard mixed with honey over roasted vegetables or meats.
