Don't buy or eat these vegetables, and be sure to tell your family

Vegetables are eaten in every household. Although many people can't enjoy a meal without meat, eating too much meat can cause all kinds of problems in the body, while some vegetables can balance the body and clear out toxins. However, some vegetables should not be eaten, as eating them can cause cancer, and those in the know won't buy them. Follow along and take a look.

1. Fresh wood ear mushrooms

Most wood ear mushrooms on the market are dried, and there is a scientific basis for this. The reason fresh wood ear mushrooms are rare is that fresh wood ear mushrooms contain a photosensitive substance called "porphyrin." After a person eats them and is exposed to sunlight, skin inflammation and rashes and the like can appear. In addition, they also increase the probability of developing cancer.

2. Pickled vegetables

Vegetables themselves contain nitrites, and if they are then pickled, the nitrite content will greatly increase. In addition, they also contain other nitrosamine substances, and these substances can all trigger cancer and tumors in the human liver and organs, with cancerous changes in the digestive tract being especially common. This is even more true of those canned pickles that have been stored for a long time, whose freshness is unknown, and which may have other chemicals added.

3. Bracken fern

Bracken fern, known as the king of wild vegetables, has been eaten in almost every household, and its nutritional value is very high. In some regions, bracken fern is even called the longevity vegetable. However, research data shows that long-term and large consumption of bracken fern greatly increases the possibility of developing stomach cancer. Quite a few experts have conducted studies in which animals were fed large amounts of it, and it has been confirmed that bracken fern does indeed contain a carcinogenic substance. This carcinogenic substance is called "ptaquiloside," and this type of substance is the chief culprit that causes cancer.

4. Stir-fried green beans

The two ends and both sides of green beans very easily retain pesticide residues, so before eating, remove the two ends of the green beans, and it is best to blanch them in water before cooking. Zucchini is not suitable for high-heat stir-frying; we need to use a hot pan with cold oil and cook over low heat, and when cutting it, cut it as thickly as possible. Enoki mushrooms, on the other hand, need to be soaked in water for two hours before eating, and when boiling them, cook them until thoroughly done. "Disease enters through the mouth," so we must be careful; nothing is more important than good health.

5. Stir-fried zucchini

Zucchini is crisp and refreshing, can regulate human metabolism, and can also help with weight loss and prevent and fight cancer, so it is deeply loved by every household. In addition, zucchini has remarkable effects for patients with gout, high blood pressure, and diabetes, and should be eaten often and in larger amounts. However, zucchini is not suitable for high-heat stir-frying, and the stir-frying time should not be too long. Otherwise, it will produce the carcinogenic substance acrylamide, and the amount of this carcinogenic substance released ranks first among vegetables.
