Raw Vegetables Can Be Healthy But These 5 Need Careful Washing and Preparation

Editoron

Water caltrop grows submerged in lakes and ponds. The black shell you see in the photo protects the white nut inside, but the shell and nut often have parasite larvae on them, especially _Fasciolopsis buski_, the giant intestinal fluke. In many Asian countries this is the #1 cause of fluke infection from plants.

*How to prepare safely:*

- *Never eat raw.* Boil the whole nut for 10-15 minutes, then crack the shell.

- Scrub the shell with a brush before boiling.

- If you must eat the nut raw in salads, buy only “pre-boiled and peeled” packaged versions from the store.

*Health tip:* Cooked water caltrop is starchy, sweet, and totally safe. It’s used in soups and desserts across China, India, and Vietnam.

*2. WATER SPINACH / KANGKONG / MORNING GLORY*

*Why it’s risky:*

This leafy green grows in ditches and wetlands. It’s a favorite for _Fasciola_ liver flukes. The stems are hollow and can trap snail larvae and eggs.

*How to prepare safely:*

- Soak in salt water or vinegar water for 20 minutes.

- Rinse each leaf and stem under running water, rubbing to remove slime.

- Best practice: lightly stir-fry or blanch for 30 seconds. You still get the crunch but kill parasites.

*Health tip:* It’s full of iron and vitamin A. Just don’t eat it straight from the market without washing.

*3. LOTUS ROOT AND LOTUS SEEDS*

*Why it’s risky:*

Lotus grows in muddy ponds. The root has lots of holes that trap mud, bacteria, and sometimes parasite eggs. Lotus seeds also sit in pods in the water.

*How to prepare safely:*

- Peel the brown skin off the root.

- Slice and soak in clean water, changing the water 2-3 times.

- Boil for 5 minutes before adding to salad, or cook fully in soup.

*Health tip:* Lotus root is amazing for gut health. Cooking makes it crisp and safe.

*4. WATERCRESS*

*Why it’s risky:*

Watercress grows in running streams. It’s beautiful in salads, but streams can be contaminated with runoff, animal feces, and _Giardia_ or _Cryptosporidium_.

*How to prepare safely:*

- Buy from reputable farms, not wild streams.

- Soak in cold water with 1 tbsp vinegar per liter for 15 minutes.

- Rinse 3 times in clean water.

- For pregnant women, kids, and seniors: lightly blanch.

*Health tip:* Watercress is a superfood for vitamin K and antioxidants. A quick rinse makes it salad-ready.

*5. BEAN SPROUTS / MUNG BEAN SPROUTS*

*Why it’s risky:*

“One day my little daughter told me, ‘Mom, every time Grandpa gives me a bath, he asks me to play a game. I have to close my eyes, and while they’re closed, he does something…’ I froze. The next day, I opened the bathroom door without warning… and what I saw made my legs start shaking My daughter, Emily, was six years old when she first said the sentence that kept me awake almost the entire night. That afternoon, we were in the kitchen. I was making dinner while she sat at the table drawing. Then, without even looking up, she said, “Mom, did you know Grandpa and I have a game?” I smiled. My father, George, was seventy-six years old, and he and Emily were almost inseparable. He picked her up from school, read her stories, and taught her how to plant flowers in the garden. “What kind of game?” I asked. Emily thought for a moment. “When Grandpa gives me a bath, he tells me to close my eyes.” The knife in my hand stopped. I turned toward her. “Why?” She shrugged. “So we can play.” Okay?” She looked at me, confused. “But Grandpa doesn’t do anything bad.” That sentence should have reassured me. It didn’t. That night, I barely slept. My father had always been the person I trusted most. Whenever my husband had to work late, Dad came over to help me. Whenever Emily was sick, he could sit beside her for hours. I had never seen anything that made me suspicious of him. But now my mind had taken one sentence and built a hundred frightening possibilities around it. The next morning, I started remembering little things that had never seemed important before. A few weeks earlier, Dad had told me, “You’re busy. I’ll get Emily ready for bed.” Another time, the bathroom door had been closed. When I knocked, I heard both of them laughing. Back then, I had smiled. Now the same memory felt completely different. All day, I kept telling myself I was overreacting. But something in me refused to let it go. The next evening, Dad came over again. After dinner, Emily ran up to him. “Grandpa, are we going to play our game today?” I looked at my father. He smiled. “If your mom doesn’t mind.” “Of course,” I said. But I had already made up my mind. Ten minutes later, I heard the water running. Then Emily laughing. I slowly walked toward the bathroom. The door was closed, but not locked. I stepped close enough to hear them. Dad said, far from every terrible thing my mind had imagined that I just stood there for a few seconds.  Emily was sitting safely in the tub, surrounded by bubbles and bath toys. Her eyes were closed. My father was holding a small cup in one hand, using it to rinse her hair, while in the other hand he held one of Emily’s rubber ducks. “Mom,” Emily laughed, “you ruined the game!” I looked at them, confused. “What game?” Dad slowly smiled. “Guess the sound.” It turned out that a few months earlier, Emily had started being afraid of having her hair washed because shampoo had once gotten into her eyes. Every bath had become stressful. My father didn’t want that fear to get worse. So he invented a game. Emily would close her eyes, and Dad would make sounds using different bath toys—the rubber duck, a little cup, a water bottle. While she tried to guess which toy was making the sound, he carefully rinsed the shampoo from her hair.  Every time she guessed correctly, she earned one “star.” After ten stars, Grandpa urm took her out for ice cream. I stood in the doorway, feeling tears fill my eyes. Dad looked at me. He understood immediately. “You were scared, weren’t you?” I couldn’t lie. “Yes.” He was quiet for a moment. Then he said, “You did the right thing by checking.” I looked at him in surprise. He continued, “A mother should always make sure her child is safe. I should have explained our game to you sooner.” Emily opened her eyes. “Mom, I told you Grandpa urm wasn’t doing anything bad.” I walked over and kissed her forehead. That evening, when Dad was getting ready to leave, he stopped by the door and said quietly, “By the way, this game isn’t new.”  “What do you mean?” He smiled. “You were afraid of having your hair washed too. When you were five, I played the same game with you.” I froze. Then suddenly, I remembered. Closed eyes.
