When people think of parasites, they often picture frightening organisms that steal nutrients and cause serious disease. In truth, parasites have been a threat to human health for thousands of years. Even today, nearly 2 billion people worldwide are infected annually, with hundreds of thousands of deaths reported.

Thanks to improved sanitation, many countries — including Vietnam — have controlled the spread of several parasitic diseases. Still, the risk of infection in everyday life remains. Surprisingly, some of the vegetables we commonly eat are considered “parasite hotspots”, especially when eaten raw or undercooked.

• Wash thoroughly: Rinse vegetables under running water, and soak them several times in diluted saltwater or clean water.
• Scrub carefully: Vegetables with grooves or fine hairs should be brushed clean. Peel root vegetables before cooking.
• Cook before eating: Heat destroys parasites. The safest way is to cook vegetables fully rather than eating them raw.
• Be extra cautious with salads: If you enjoy raw vegetables, always select the freshest produce and soak it thoroughly before serving.

Bottom Line

While fresh vegetables are essential for a healthy diet, careless eating habits can turn them into a hidden source of parasites. The golden rule remains simple: cook your food and boil your water. By practicing safe food preparation, you can enjoy your meals without unknowingly “inviting” parasites into your body.
