Nature’s Gifts of Vegetables and Fruits – But Are They Always Healthy?
Have you ever thought that seemingly harmless foods can be dangerous to your health? Potatoes, cassava, fresh bamboo shoots, and green tomatoes are all common ingredients in Vietnamese cuisine, but if not prepared properly, they can have serious negative impacts. So, how can we enjoy their nutritional value while staying safe?
Sprouted Potatoes: The Hidden Danger of Solanine
Sprouted potatoes contain the toxin solanine, a natural glycoalkaloid compound that can cause nausea, headaches, and even digestive disorders when consumed. According to Dr. Nguyen Thi Lam, Deputy Director of the National Institute of Nutrition, even a small amount of sprouted potatoes can lead to acute poisoning.
To ensure safety, thoroughly inspect potatoes before cooking. If you notice any sprouting or abnormal green color, it’s best to discard them instead of trying to cut off the sprouts. Are you confident that you’re always cautious with each potato in your kitchen?

Cassava: The Potential Danger of Cyanide
Cassava is a favorite dish for many families, but few know that it contains cyanogenic glycosides, which produce the deadly toxin cyanide. According to research from the Ministry of Health, eating cassava that hasn’t been properly processed can lead to symptoms like dizziness, difficulty breathing, and even death in severe cases.
The safe handling practice is to soak cassava in clean water for at least 4-6 hours, then boil it thoroughly and change the water 2-3 times. Remember, don’t skip the preprocessing steps, as they ensure the safety of your family.

Fresh Bamboo Shoots: Delicious but Potentially Toxic
Fresh bamboo shoots also contain cyanide, especially bamboo and bamboo shoots. To remove the toxin, nutritionist Tran Thi Minh Nguyet recommends boiling the bamboo shoots at least twice for about 10 minutes each time and soaking them in a dilute salt solution before cooking.
Are you sure you’ve applied all the necessary steps to process fresh bamboo shoots? This is a thought-provoking question to avoid unwanted consequences.
Green Tomatoes: Tomatine, the Poison in the Green Hue
Green tomatoes contain tomatine, an alkaloid that can irritate the stomach and affect the digestive system. Dr. Hoang Dinh Khanh, a food safety expert, emphasizes that tomatoes should only be consumed when they are fully ripe to ensure safety.
Take a look inside your refrigerator – are there any green tomatoes waiting to be prepared?
Raw Beans: Lectin and the Risks of Eating Them Raw
Beans such as kidney beans and kidney beans contain lectin, a protein that can cause intestinal inflammation and digestive disorders. According to a 2023 survey by the Vietnam Food Safety Association, more than 60% of bean poisoning cases resulted from undercooking.
Prevention is simple: Always soak beans for at least 8 hours before cooking and boil them at a high temperature for at least 15 minutes. Have you been following these steps?
Wild Mushrooms: The Danger of Unknown “Caps”
Wild mushrooms are a leading cause of food poisoning in Vietnam. According to a report by the Bach Mai Hospital Poison Control Center, there are about 300 cases of mushroom poisoning each year, many of which result in death.
Experts warn: Only use mushrooms from a clear source and never eat wild mushrooms, no matter how tasty they look. Can you confidently distinguish between safe and poisonous mushrooms?
