Nutritional benefits of seasonal Vietnamese produce

Seasonal produce in Vietnam, such as water caltrops and water spinach, offers significant nutritional value. Water caltrops, which are in season from July to September, are characterized by a hard black shell and a starchy white interior. They contain approximately 49% starch and 10.3% protein, along with vitamins B1, B2, PP, C, and minerals such as calcium, iron, and manganese. While often called a nutritional treasure, experts caution against viewing them as a medical cure for ailments like jaundice or high blood pressure.

Similarly, water spinach is a widely available and affordable leafy green that provides protein, fiber, vitamin C, B vitamins, and essential minerals like iron and magnesium. Health benefits associated with water spinach include supporting liver function through antioxidant properties, protecting cardiovascular health by reducing oxidized cholesterol, and helping to naturally lower blood pressure due to its magnesium content.
