When embarking on a weight loss journey, a reduction in calorie intake is typically the first step. This often involves making healthy adjustments to one's diet to facilitate shedding kilos and toning the body. Contrary to popular belief, healthy eating doesn't have to equate to bland and unappetizing meals. With the right ingredients, even nutritious foods can be flavorful and satisfying. Mustard seeds are one such ingredient that can be incorporated into your diet to support weight loss goals.
The Nutritional Profile of Mustard Seeds
Mustard belongs to the same family of nutrient-rich leafy vegetables as cabbage, broccoli, and kale, known as cruciferous vegetables. Both the seeds and leaves of the mustard plant possess culinary value, and it is renowned for its medicinal properties and pungent taste. Modern science has begun to recognize the diverse health benefits offered by this plant.
There are numerous varieties of mustard, all of which are rich in nutrients. Mustard seeds, in particular, are abundant in minerals such as copper, calcium, iron, magnesium, phosphorus, potassium, sodium, zinc, manganese, and selenium. They are also a good source of vitamins C and K, thiamin, riboflavin, vitamin B6, and folic acid. Furthermore, mustard seeds boast a high percentage of dietary fiber and are a valuable source of bioactive compounds like antioxidants and polyunsaturated fatty acids.
A 20-gram serving of mustard seeds provides approximately:

Fiber Content and Calorie Burning
According to some research, the fibers in mustard seeds are difficult to digest, which requires the body to expend more energy and burn more calories in the process. Additionally, the fiber content promotes a feeling of fullness, which can help prevent overeating.
Metabolism Boost
A study conducted by scientists at England's Oxford Polytechnic Institute found that consuming 1 tablespoon of mustard seeds can boost metabolism by up to 25 percent for the subsequent 3-4 hours.
Low in Calories, Rich in Antioxidants
Mustard seeds are low in calories and packed with antioxidants, offering potential benefits in the fight against cancer and Alzheimer's disease.
The Science Behind Mustard's Potential Effects
Mustard seeds contain sinigrin, which is responsible for their pungent taste. When digested, sinigrin breaks down into allyl isothiocyanate (AITC). Research indicates that AITC exhibits antimicrobial properties that can protect against various bacterial strains. Sinalbin, present in some mustard species, also breaks down into a type of isothiocyanate and has demonstrated even more potent antimicrobial properties than sinigrin.
Studies have also shown that AITC can inhibit enzymes essential for bacterial metabolic activities, leading to membrane damage and reducing their harmful impact. The antibacterial activity varies depending on the type of mustard seed, which influences the glucosinolate content. However, all types of mustard seeds exhibit considerable antimicrobial activity.

Phenolic compounds, abundant in mustard seeds, are known for their antioxidant activity, reacting with free radicals in the body and inhibiting their harmful effects. Mustard seeds also contain tocopherols, which are fat-soluble compounds and part of the vitamin E family with extensive antioxidant capabilities. Research suggests that sinigrin can reduce the production of nitric oxide, a chemical linked to the formation of free radicals.
Sinigrin has also been shown to cause cancer cell death, although the exact mechanism is still under investigation. It is hypothesized that sinigrin modifies certain enzymes, lowering the risk of DNA damage to tissues targeted by cancer-causing agents.
Furthermore, research has found that sinigrin enhances wound healing abilities when combined with lipid-based phytosomes, which improve the absorption of herb-based chemicals like sinigrin.
Recent Research on Mustard Seeds and Health Conditions
Recent studies have explored the potential benefits of mustard seeds for specific health conditions.
Lower Blood Sugar Levels: A study in the Philippines indicated that mustard seed extracts, when taken with blood sugar medication, may help lower blood sugar levels in individuals with type 2 diabetes.

Thermogenesis and Energy Expenditure: Research in mice showed that allyl-isothiocyanate (AITC), the pungent component of mustard, activated brown adipose tissue (BAT) and increased energy expenditure. However, a human crossover study found that the highest tolerable dose of mustard did not elicit a relevant thermogenic response.
Incorporating Mustard Seeds into Your Diet
Eating mustard alone will not lead to weight loss. It must be combined with a healthy diet to maximize its benefits and reduce body fat. Mustard seeds can be added to curries, salad dressings, and eggs. Mustard oil can also be used in small amounts for cooking.
Mustard is produced from crushed mustard seeds and is commonly used as a condiment to enhance the flavor of Asian and Mediterranean dishes. With an increasing focus on natural ingredients, mustard is becoming a preferred component in the preparation of new products.
- Yellow mustard seeds are commonly used in ready-to-eat foods such as sandwiches or dips.
- Brown mustard seeds are spicier and used in Asian dishes to add flavor.
- In Indian preparations, mustard seeds are heated in clarified butter or oil with other spices before being added as a final flavoring.
Additional Health Benefits of Mustard Seeds
Mustard seeds are known as a rich source of glucosinolates and omega-3 fatty acids, compounds widely recognized for their health benefits, including reducing inflammation and lowering the risk of cardiovascular diseases and cancer.
Glucosinolates and Omega-3 Fatty Acids
Glucosinolates (GSLs) are composed of β-thioglucose, thiohydroximate-O-sulfonate, and a variable aglycone side chain derived from an α-amino acid. Omega-3 fatty acids are PUFAs containing more than one carbon-carbon double bond in their backbone. Consumption of glucosinolates can have anticarcinogenic properties and contribute to the bioactive nature of mustard seed oil.
Clinical Studies on Mustard Seeds
While traditionally used in Asian medicine, only a few human studies have confirmed the bioactivities of mustard seeds and their main compounds.
Auriculotherapy: Studies have shown that applying white mustard seeds to auricular acupressure points can reduce body weight, body mass index (BMI), fatigue, and anxiety, and improve sleep quality.
Respiratory Tract Infections: Mustard seed powder footbaths have been shown to improve symptoms of respiratory tract infections.
Oral Malodor: Chewing gum with allyl isothiocyanate and zinc salts can decrease volatile sulfur compounds in the breath.
Glycemic Response and Satiety: Adding yellow mustard bran to soup may affect glycemic response and satiety.
Skin Integrity in Neonates: Mustard seed oil massage in neonates may affect skin pH, dryness, erythema, and rash.
Alpha-Linolenic Acid (ALA)
Alpha-linolenic acid (ALA) is the main fatty acid in mustard seed oil. Studies have explored its associations with ischemic stroke, plasma long-chain n-3 polyunsaturated fatty acids PUFAs, and ketogenic response. Some studies suggest that diets rich in ALA may not influence parameters altered in type 2 diabetes (T2DM). However, ALA supplementation may counteract the severity of multiple sclerosis (MS). A combination of ALA and quercetin may reduce total cholesterol, apolipoprotein B, and low-density lipoprotein cholesterol. ALA-rich diacylglycerol (ALA-DAG) may reduce BMI, visceral fat area, and fasting TAG serum concentration in obese patients and enhance fat utilization.
Mustard as a Weight Loss-Friendly Condiment
Mustard stands out as a weight loss-friendly condiment, offering very low calories while enhancing flavor and potentially boosting metabolic burn. Compared to condiments like ketchup and mayo, mustard provides a healthier alternative for those seeking to manage their weight.
Spicy Foods and Digestion
Certain spicy food additives, including mustard, can reduce acidity in the digestive tract and stimulate the production of gastric juices, aiding digestion.
Extraction and Isolation of Glucosinolates and Omega-3 Fatty Acids from Mustard Seeds
Glucosinolates are extracted from mustard seeds using a polar solvent, such as aqueous methanol or water, to inactivate myrosinase activity. The extracted sample is then vortexed, centrifuged, and filtered. Seed defatting may be performed before glucosinolate analysis. High-performance liquid chromatography (HPLC), gas chromatography with mass spectrophotometry (GC-MS), or enzyme-linked immunosorbent assay (ELISA) are used to analyze the extracts.
