After surgery for thyroid cancer five years ago, Zee, 65, has concentrated on eating healthy food. She can’t be beaten by one banana a day. The banana is soft, glutinous, and sweet so that you don’t have to worry about bad teeth and mouth, it can also relieve constipation, so it is her favorite fruit.

Yesterday, Aunt Zee went as usual for one and got a shocking video as soon as she took a bite. The video states that bananas are the “most radioactive” one, among other things, it shows experimental tests from foreign countries, and long-term use may cause cancer. Besides, the host warned that cancer patients should be careful while eating.

Aunt Zee holding the banana in her hand came to her mind the difficult and long battle against cancer. Her heart was riddled with questions. Has a healthy habit that has been her companion for so many years been quietly harming her body?

1. Bananas “bring your own radiation”, can eating them regularly cause cancer?

The healthiness inside the banana is so amazing that it becomes a favorite food with the majority of people. However, in recent years, the web is full of rumors about bananas. From those, one claims that bananas are highly radioactive fruits. Regular intake can easily cause cancer. How is it really?

To be fully honest, bananas do give off radiation, and that radiation is mostly due to the fact that the fruit is rich in potassium which is one of the major constituents of the muscles and the nervous tissue of the body. If only the body is lacking in potassium, it will result in the abnormal electrocardiograms, irregular heartbeats, etc., and even the cessation of the heartbeat can happen. Potassium “brother” potassium-40 is a potasium radioactive isotope and it is the main source of natural radiation for the human body. It is also the radiation in bananas that comes from here.

Yet “the potassium-40 content in bananas is nothing compared to the amount that can cause cancer”. The extra dose of ionizing radiation from a typical banana is around 0.0778 microsieverts and a chest CT is equivalent to the radiation from about 70,000 bananas. “Our body will regulate the potassium content in the body. When we eat more bananas, the surplus potassium that will be metabolized and will not be stored in the body,” the author explains.

For your information, not all bananas are safe to eat. If the skin of a banana is black and has cracks, and the pulp inside has turned black, or white/gray-green mold filaments appear on both ends of the banana, discard them promptly to avoid any potential health hazards.

Those who suffer from high blood sugar, kidney disease, and blood potassium, are recommended not to eat bananas. Even healthy people have to limit the daily consumption of bananas to 1-2 fruits.

2. Do you believe the “cancer-causing fruit” that has been widely circulated on the Internet?

Those who suffer from high blood sugar, kidney disease, and blood potassium, are recommended not to eat bananas. Even healthy people have to limit the daily consumption of bananas to 1-2 fruits.

1. Raking tangerines with acid-reducing agents?

Currently on the Internet, there is a talk that the rake tangerines available on the market have already been treated by acid-reducing agents. Moreover, “acid-reducing agents consist of arsenide which is arsenic. Regular consumption of them can lead to cancer” is also stated.

“If you buy rake tangerines from regular dealers, you can eat them with confidence and don’t have to be too worried.” It is “three-no” products that have been broadly circulated on the Internet rake tangerines, which were added with antacids. The relevant food safety management in our country forbids the use of arsenate-containing substances, such as acid-reducing agents, and merchants who illegally add will be punished by the law

2. Is blueberry “white cream” pesticide residue?

I think many people might have heard this but it is a lie. Blueberry on top Whitecream is a fruit powder secreted by the blueberries themselves, this fruit powder is mainly a long chain aliphatic compound, insoluble in water and difficult to clean. It will not cause any harm to the body, and it will protect blueberries from germs and avoid water evaporation in blueberries. It can be said that blueberries with glaucous frost are fresher..

3. Apple seeds contain cyanide?

Apple seeds have a cyanogenic glycoside component from which one cannot ignore the dose when talking about toxicity. The cyanide is bound to the glycoside and in order to convert the compound to toxic hydrogen cyanide they need to be chewed and the acid from the stomach has to decompose the cyanogenic glycoside. It is necessary to chop up 200 apple seeds, which results in approximately 40 apples to make the conversion. So it is very difficult to do and you don’t have to worry about it at all.

I. Fruit cutting trap

Most people like fruit cutting because it is easy and quick and you can also eat different fruits. However, the area of the fruit that is exposed increases and it can become a source of bacteria and mold. In addition, many fruit cutting shops will use new methods to decrease the cost of cutting and will take some fruits that are moldy to cut and continue to sell. This kind of food is very harmful to health after eating.

II. Moldy fruits

If a piece of fruit has gone moldy, it is very likely that the fruit contains aflatoxin, a type of carcinogen that can cause the liver to be damaged and thus lead to liver cancer.

Do not take parts that are not moldy and eat them because they may also be infected with mold. Instead, throw the whole fruit away.

III. Betel nut

Areca nuts are one of the most carcinogenic substances that are listed by WHO as class 1 of carcinogens, the regular consuming of betel nut is the main factor that causes different types of cancer such as oral cancer, esophageal cancer, and gastric cancer. This is due to the fact that “the three – arecoline, polyphenols, and other substances – in betel nut are the most cytotoxic, and that the texture of betel nut is hard that will irritate the oral mucosa and esophageal mucosa when chewed, and can easily promote mucosal cancer over time”.

When selecting fruit in life, you must pick the fresh one, that is free from damage and mold, and it is better to select products from safe and secure shopping places. As soon as you get home from the purchase, eat it quickly, and store the unfinished food in a cool, well-ventilated place away from direct sunlight.

4. “Enjoy fruits healthily. Two more ways are recommended”

A survey done by our experts claims that the average of fruit intake of the local people is less than the recommended amount in the dietary guidelines (200~350g) with only 40,7 grams of fruit per day on average. Besides, lack of fruit intake is the major controllable risk factor for the development of cancer. You have to eat fruits for the sake of your health! These 2 ways are highly recommended.

I. Add vegetables

Fruits can not only be eaten raw, but can also be eaten by cooking, such as stewing apples, carrots, and corn together, which can increase the nutritional value of the soup, neutralize the acidity of the fruit, and reduce irritation to the stomach.

II. Fruit tea/porridge

There are some people with sensitive digestive systems for whom eating fruit can easily cause diarrhea and in such case fruit can be made into fruit tea or fruit porridge. For instance, “One can prepare fruit tea from apples and pears. Red dates and wolfberry which is nutritious and delicious can be added in suitable amounts”.

Most of the rumors about fruits on the Internet are false. We must learn to identify them and not let some unfounded rumors affect our normal lives. The gains outweigh the losses.
