Green mustard, also known as caisim (Brassica rapa subsp. parachinensis), is one of the most popular leafy green vegetables in Indonesia. Known for its freshness and savory-sweet taste with a slight bitter undertone, green mustard is not only delicious but also a nutritional powerhouse that offers a myriad of health benefits.
Benefits of Consuming
Green Mustard (Caisim) for Health
Green mustard is low in calories and fat but high in fiber, vitamins, and minerals. Its potent antioxidant properties, derived from its content of Vitamin C, flavonoids, and beta-carotene, make it a superfood choice for supporting optimal health.
1. Supports Heart Health
Green mustard contains fiber, potassium, calcium, and magnesium, all of which play a crucial role in maintaining heart health.
- Lowers Cholesterol: Compounds in the mustard greens help bind bile acids in the digestive system, preventing reabsorption, and effectively helping to lower bad cholesterol (LDL) levels.
- Regulates Blood Pressure: Potassium, calcium, and magnesium can help naturally reduce blood pressure, prevent plaque buildup, and mitigate the risk of cardiovascular diseases.
2. Strengthens Bones and Prevents Osteoporosis
Caisim is an excellent source of Vitamin K (one cup of boiled caisim can provide over 100% of the daily requirement).
- Bone Health: Vitamin K works with calcium and phosphorus in the formation and maintenance of bones, enhancing calcium absorption, and preventing conditions like osteoporosis.
3. Boosts the Immune System
The high levels of Vitamin C and Vitamin A make green mustard excellent at enhancing the body's resilience.
- Cell Protection: Vitamin C acts as an antioxidant, protecting cells from damage caused by free radicals and increasing the production of white blood cells to fight infections.
- Fights Disease: Certain compounds in mustard greens can also strengthen the body's response against pathogens.
4. Maintains Eye Health
Green mustard is rich in Vitamin A and antioxidants like beta-carotene, which are essential for visual function.
- Prevents Damage: Vitamin A protects the eyes from cellular damage, helps prevent night blindness, and lowers the risk of macular degeneration.
5. Has Anti-Cancer Properties and Fights Free Radicals
Green mustard contains high concentrations of antioxidants and isothiocyanate compounds.
- Reduces Cancer Risk: Regular consumption of green mustard has been linked to a reduced risk of certain cancers, including prostate, colon, stomach, and lung cancer.
6. Improves Digestion and Detoxification
The high fiber content helps facilitate bowel movements and maintain gut health. Additionally, mustard greens have mild detoxification capabilities by assisting in the removal of excess salt fluids and preventing toxin deposition in the kidneys.
Side Effects of Consuming
Green Mustard (Caisim)
Despite its many benefits, the consumption of green mustard should be monitored in certain health conditions:
Side Effect, Condition to Be Cautious About, Reason
- Blood Clotting Interference
- People taking blood thinners (like Warfarin)
- The high Vitamin K content can interfere with the function of blood-thinning medications, as Vitamin K plays a vital role in the blood clotting process
- Increased Kidney Stone Risk
- Sufferers of Kidney Disease or those with a history of kidney stones
- Mustard greens contain oxalates. Excessive oxalate consumption can increase the risk of kidney stone formation in susceptible individuals
- Increased Gas and Heartburn
- Sufferers of Acid Reflux/GERD
- Green mustard is a vegetable that produces gas in the digestive tract, which can trigger or worsen acid reflux symptoms
Important: If you have any of the above health conditions or are taking specific medications, consult a doctor about the safe amount of green mustard consumption.
Tips for Optimal Green Mustard (Caisim)
Preparation for Maximum Results
To get the maximum nutritional benefits, the way green mustard is prepared is crucial. Water-soluble vitamins (like Vitamin C) and those sensitive to heat can be lost if cooked for too long.
Preparation Method, Tips for Maximum Nutrition, Advantages
- | Raw/Lalapan
- Ensure the mustard greens are thoroughly washed under running water before consumption
- Highest nutrient retention (all vitamins and minerals intact)
- Quick Stir-fry
- Use high heat and cook only for 2-3 minutes until wilted. Use a little healthy oil (olive/coconut) to aid the absorption of fat-soluble vitamins (like Vitamin A and K)
- Crisp texture and flavor are maintained, and Vitamin A and K are well-absorbed
- Steaming
- Steam the mustard greens for only about 5 minutes until cooked
- Retains more nutrients compared to boiling, as they are not submerged in water
- Blanching (Short Boiling)
- Boil in water for 30 seconds - 1 minute, then immediately remove and immerse in cold water
- Maintains a bright green color and removes some bitterness, while preserving most of the Vitamin C
Additional Tips:
- Wash Before Chopping: Wash the mustard greens whole under running water. Chopping before washing can cause more nutrients to leach into the water.
- Cook Quickly: The main key for all cooking methods is a short cooking time to preserve Vitamin C and antioxidants.
- Selecting Ingredients: Choose mustard greens with bright green and fresh leaves; avoid those that are wilted or yellowing.
By integrating properly prepared green mustard into your diet, you can enjoy the optimal health benefits of this nutritious green vegetable.
