For a long time, when people go shopping for fruits and vegetables, they often try to find places selling produce that is clean, affordable, and “in season” to minimize the risk of harmful chemicals. However, besides these common criteria, there are many fruits that, despite tasting good, being nutritious, and cheap, actually contain toxins that can stimulate the growth of cancer cells. So, what are these dangerous fruits?

After reading reports in the news, I found the answer and want to share it here to raise awareness. Next time you go to the market, be sure to carefully select fruits that are beneficial for your family without harmful side effects.

Experts Recommend Avoiding These 5 Types of Fruits Because They Can Cause Cancer

---

1. Moldy or Rotten Fruits: Contain Aflatoxins That Cause Liver Cancer

Many people are tempted to buy fruits that look wilted, moldy, or rotten because they are cheaper. However, such fruits not only lose their sweet flavor and nutrition but also pose serious health risks. Consuming moldy fruits can lead to digestive issues such as nausea, vomiting, diarrhea, and abdominal bloating.

More importantly, molds sometimes produce dangerous toxins called aflatoxins, which have been confirmed by the World Health Organization (WHO) as carcinogenic and specifically linked to liver cancer. These toxins do not just grow on the surface but penetrate deep into the fruit. So even if you cut off the moldy part or cook the fruit at 100°C, the risk of poisoning remains.

2. Betel Nut and Betel Leaf: Linked to Mouth Cancer

Betel nut (areca nut) and betel leaves are traditional chewing items in many Asian countries, including Vietnam. However, chewing betel nut and betel leaf causes strong abrasion to the mucous membranes of the mouth, leading to peeling or scratches on the upper layer of the oral mucosa. Moreover, the toxins present in betel leaves, betel nuts, lime, and tobacco cause further damage to the already injured areas, increasing the risk of oral cancer.

Studies have shown that chemicals like arecoline and arecaidine found in betel nuts increase saliva secretion, reduce heart rate, and stimulate the nervous system. This explains why many people feel their face flushes or appears rosy after chewing betel nut, similar to the effect of alcohol consumption.

3. Frozen Fruits: May Produce Nitrites That Increase Cancer Risk

During hot weather, many people choose frozen fruits for convenience and longer shelf life. However, tropical fruits generally do not preserve well in freezing conditions. When frozen, some fruits can produce nitrites, which are potentially carcinogenic and increase the risk of cancer when consumed.

4. Waxed Apples: Prolong Shelf Life But May Cause Blood Cancer

Have you noticed the white wax coating on the surface of some apples? This protective wax is applied by sellers to extend the fruit's shelf life.

Some companies produce wax made from natural ingredients like beeswax, red ant wing resin, or carnauba wax, which are generally safe. However, these natural waxes are expensive.

Therefore, the wax often used on fruits contains heavy metals such as mercury, lead, formaldehyde, or industrial dyes. Eating wax-coated apples regularly can weaken your immune system and increase the risk of blood cancer.

5. Ripe Bananas Treated with Chemicals: May Cause Early Puberty and Increase Blood Cancer Risk

Bananas are a popular fruit with many nutritional benefits. However, because they bruise easily during transport, sellers often pick green bananas and soak them in chemicals containing formaldehyde or ripening agents to make them ripen evenly and last longer.

These chemicals are very harmful to the body. Long-term consumption of chemically treated ripe bananas can cause early puberty in children and increase the risk of blood cancer.

Additional Notes:

Many consumers are unaware of the hidden dangers lurking in fruits that appear fresh or taste good but have been treated or preserved using harmful substances. It's important to buy fruits from reputable sources and, if possible, buy seasonal fruits that have not been artificially preserved. Washing fruits thoroughly and peeling skins when necessary can also help reduce risks.

Taking small precautions in your daily fruit choices can significantly reduce exposure to toxins and help maintain your long-term health.
