5 Vegetables and Fruits That May Harm the Liv.er – WHO Adds Them to the ‘Blacklist’

The liv.er plays a crucial role in deto.xifying the body, yet certain common vegetables and fruits can be harmful if not consumed properly. Let’s explore five foods to watch out for to keep your liver healthy.

 

 

 

The Liver’s Vital Role and Its Connection to Food

Despite being a small organ, the liver is essential to overall health. It aids in digestion, detoxifies the blood, and processes nutrients. However, an unhealthy diet—such as consuming too many oily foods, fermented foods, or spoiled ingredients—can put tremendous stress on the liver.

Surprisingly, even everyday vegetables and fruits can become harmful if they’re not handled or prepared correctly.

According to Assoc. Prof. Dr. Nguyễn Thị Lâm, former Deputy Director of the National Institute of Nutrition:

“Consuming unsafe foods, especially contaminated or spoiled vegetables and fruits, can lead to toxic buildup in the liver, increasing the risk of hepatitis, cirrhosis, and even liver cancer.” (Source: Sức khỏe & Đời sống)

So, which foods does the World Health Organization (WHO) warn against? Here’s the list:

---

1. Long-Soaked Wood Ear Mushrooms

Wood ear mushrooms (also known as black fungus) are a popular ingredient in many dishes. However, soaking them in water for too long can promote bacterial growth and lead to the production of aflatoxin, a highly toxic substance that can cause acute liver inflammation and severe liver damage.

How to avoid harm:
✔ Do not soak wood ear mushrooms for more than two hours.
✔ Rinse them thoroughly before cooking.

2. Sprouted Potatoes

Sprouted potatoes contain high levels of solanine, a natural toxin that can cause digestive issues and liver damage. Since solanine is hard to break down, the liver must work overtime to eliminate it, which increases stress on the organ.

How to avoid harm:
✔ Check potatoes carefully before buying.
✔ Never consume sprouted or greenish potatoes.

3. Pickled Vegetables

Pickled foods like fermented mustard greens, salted eggplant, and kimchi are staples in many households. However, if not properly fermented, they can produce nitrosamines, which have been linked to liver cancer.

According to Dr. Trương Hồng Sơn, Director of the Vietnam Institute of Applied Medicine:

“Poorly fermented foods may contain nitrosamines, which can increase the risk of liver cancer.” (Source: VnExpress)

How to avoid harm:
✔ Prepare pickled foods at home using clean, safe fermentation methods.

4. Leftover Vegetables

Many people cook extra vegetables and store them in the fridge for later. However, overnight vegetables can produce nitrates, which convert into nitrites—compounds that can harm liver cells over time.

How to avoid harm:
✔ Cook just enough for one meal.
✔ If storing leftovers is necessary, reheat them thoroughly before eating.

---

5. Moldy Vegetables

Moldy vegetables lose their nutritional value and may contain dangerous fungal toxins like aflatoxin and ochratoxin, which attack the liver and cause inflammation and deterioration.

How to avoid harm:
✔ Always inspect vegetables before cooking.
✔ Discard immediately if you notice mold or an unusual smell.

✔ Eat antioxidant-rich foods like turmeric, green tea, garlic, and vitamin C-rich fruits to support liver function.
✔ Drink at least 2 liters of water daily to aid detoxification.
