Li Tuan from the Gastroenterology Department of Shanghai Changhai Hospital (China) warned that 7 types of vegetables should not be purchased because they are very dangerous for health.
1. Deformed tomatoes
When buying tomatoes, you will often find tomatoes that are deformed on the outside. Sellers will often say, home grown tomatoes, don’t look good but have no pesticide, don’t eat them all before selling and they’re not cheap.
The fact that tomatoes are deformed is mainly due to the unsuitable temperature of the tomatoes during the differentiation of flower buds, and the lack of nutrients during the growth period. Especially raw tomatoes which contain a certain amount of solanine, if eaten too much will cause nausea, vomiting, dizziness, and even poisoning.
Normal ripe tomatoes should be round, bright red, tender to the touch, not rotten, and green stalks of delicious, high-quality tomatoes.
2. Cucumbers have flowers on top and small nodules
Many people buy cucumbers, see melons with flowers on them and have nodules, thinking they are fresh cucumbers. In fact, in ripe cucumbers, the flowers on the top wither, and the spines on the cucumbers are relatively short.
If it is ripe due to hormones or using too many hormones, cucumbers have flowers and nodules under the flowers. Therefore, when you find such cucumbers, you should not buy them.
3. Potatoes with potato sprouts
As we all know, sprouted potatoes are not edible, so some sellers will cut the sprouts on sprouted potatoes, then sprinkle a little soil over the sprouts to keep the cuttings moist, the soil will stick. Therefore, people when choosing will think that these potatoes are fresh, but they are actually sprouted potatoes.
Potato sprouts will produce toxic solamin, which is a relatively strong irritant to the stomach lining, which affects the central nervous system. If you eat sprouted potatoes, there is a risk of stomach pain, diarrhea, vomiting, and even severe respiratory failure.
Distinguishing ungerminated potatoes is very simple, remember not to think that the soiled tubers are still fresh, you can also use your fingernail to remove the soil to see if the inside is potato peel or cut potato tubers.
4. Sweet potato with black spots
If sweet potatoes are left in an unsafe environment for a long time, they will develop black spots, mildew, and an unpleasant odor. Sweet potatoes are infected with black striped bacteria, but there are still many people who buy them cheaply. In fact, even boiled or baked potatoes will not be able to destroy the poison, so when eaten they can be poisoned with symptoms such as shortness of breath, nausea, diarrhea… Therefore, when they go to the market, they see Potatoes with this sign definitely should not be bought.
5. Moldy Garlic
Garlic is a “miracle ingredient” that has antiseptic and anti-inflammatory effects, has a very high nutritional value. However, when choosing garlic, many people find that the bottom of the garlic is moldy, but touching the garlic is still difficult, so they think that the garlic is edible. In fact, as long as garlic is moldy, basically the whole garlic will have moldy filaments, which are not fit for consumption. Experts warn that aflatoxins in moldy foods contribute to liver cancer.
It’s a good idea to choose garlic bulbs that are dense, firm hands (note that garlic that is too large won’t smell good). The type of garlic we have, the outer skin is slightly purple, and the small tubers are the most fragrant. Do not choose bulbs that are bruised, soft, or runny.
6. Cracked Radish
Many people when buying radishes, whether they are green, white or purple, only observe whether the radishes are soft or not, because radishes are mushy due to insufficient water and long storage time. However, if the water is sufficient and the radish is cracked, you should not buy it.
Broken radish often lacks water, bacteria and insects and worms can enter through this gap, affecting the quality, taste and harmful to the body. His advice is to only buy turnips without cracks.
7. Bean sprouts without roots
Sprouts eaten in spring – summer are not only delicious but also nutritious. Sprouts contain many vitamins, especially vitamins C, E. Also rich in amino acids, protein and nutritious plant substances.
However, if you go to the market and see sprouts without roots, don’t buy them. Because they want the bean sprouts to be fat and fast growing, some people can add chemicals to stimulate growth, making all parts of the bean sprouts absorb water, so that root development is less.
These chemicals can contain many carcinogens and are highly toxic. This not only damages the nutritional value of vegetables but also affects the health of the user, eating too much can even cause liver damage.
How to select and distinguish ordinary bean sprouts?
Since bean sprouts will take time to grow naturally, clean bean sprouts usually have long roots that show small branches compared to bean sprouts with short, dark, dark roots that have been chemically soaked.
It is better to choose a bean sprout that is a bit thin, not the same length, milky white in color, with a sturdy stem, then it is a natural bean sprout. On the other hand, chemical bean sprouts will be more beautiful, the body long and bright.
