Water spinach, a ubiquitous vegetable in the Vietnamese cuisine, is highly valued for its affordability and delicious, crunchy taste. It can be easily prepared into various delectable dishes, such as stir-fried or boiled. Remarkably, water spinach offers a plethora of health benefits that might not be known to everyone. It is rich in water, vitamin A, vitamin C, iron, and other minerals crucial for the body.
In traditional medicine, water spinach is believed to have a sweet flavor, cooling properties, and the ability to clear heat, promote urination, and eliminate toxins from the body, including those from fungi and cassava. Modern medical research has corroborated these health benefits of water spinach.
Lowering Cholesterol and Blood Pressure
Water spinach contains a high amount of fiber, which plays a significant role in aiding cholesterol reduction and improving cardiovascular health. A fiber-rich diet is often linked to benefits in reducing the risk of conditions related to high cholesterol. Studies suggest that water spinach has the potential to decrease the levels of blood fats, particularly triglycerides, a factor that can contribute to the hardening of the arteries and the risk of stroke. Additionally, water spinach contains nitrates, a compound that can help dilate blood vessels and lower blood pressure, contributing to the protection of the circulatory system.
Lowering Blood Sugar
Consuming fiber-rich vegetables like water spinach can contribute to effective blood sugar management. When consumed before meals, water spinach helps in preventing spikes in blood glucose levels. Moreover, the natural nitrates present in water spinach also play a role in reducing blood glucose levels.
Studies have shown that water spinach can slow down the digestion of carbohydrates, thereby aiding in blood sugar management. Furthermore, water spinach enhances the body’s ability to resist oxidative stress, a factor contributing to the development of chronic diseases. This makes water spinach a valuable dietary choice for individuals managing diabetes or those at risk of developing the condition.
Providing Calcium for Healthy Bones and Joints
Water spinach provides around 77mg of calcium per 100g, contributing to stronger and healthier bones and joints. This helps prevent osteoporosis, reduces bone pain, and improves mobility in the elderly.
Relieving Digestive Issues, Constipation
Owing to its laxative and digestive-stimulating properties, water spinach can help alleviate symptoms of indigestion and constipation. It is a great dietary choice for individuals who frequently experience these issues.
Enhancing Iron Levels
Water spinach, being rich in iron, helps prevent anemia, reduces menstrual pain, and is highly beneficial for the health of pregnant women.
Boosting Eye Health
Water spinach, with its high concentration of carotenoids, vitamin A, and lutein, provides essential nutrients for eye health. It also helps boost glutathione, a natural antioxidant in the body that plays a crucial role in preventing cataracts.
Strengthening the Immune System
According to data from the USDA, every 100g of water spinach provides an impressive 55mg of vitamin C, an amount higher than that found in oranges. Vitamin C helps strengthen the immune system, combat aging, and is beneficial for cardiovascular health.
However, it is important to note that vitamin C content can be reduced when vegetables are cooked with high amounts of salt or overcooked, making it advisable to steam or boil water spinach and limit the use of seasonings to preserve as many nutrients as possible.
Water spinach offers numerous other benefits beyond those mentioned, including promoting better sleep, protecting the liver, aiding in cancer prevention, helping control body weight, reducing the risk of skin diseases, and preventing hair loss.
Cautions When Consuming Water Spinach
Despite its health benefits, water spinach should be avoided by individuals with gout, open wounds or cuts, or those taking traditional medicine, as it may cause problems such as keloids and interfere with the effectiveness of medications. Those with kidney stones or urinary tract infections should also refrain from consuming water spinach.
It is essential to cook water spinach thoroughly to avoid the risk of parasite infection. Never consume raw water spinach. Before cooking, the vegetable should be thoroughly washed multiple times with water and soaked to remove any chemicals that may be present on the leaves.
