5 most “poisonous” drinks on the black list that cause cancer

“Water is the source of life” – the body cannot exist without water. However, not all types of water are suitable for drinking, even some water can cause cancer for human.

The following types of water have been proven to be toxic and deserve to be placed on the “black list”, the second type has been warned by WHO.

5 drinks on the black list that are harmful to health

1. Solid tea

Drinking tea properly can promote digestion, good health and protect blood vessels. However, you have to control the concentration of the tea leaves. Condensed tea contains a lot of fluoride, if you drink it regularly, it can be harmful to the kidneys because the kidneys are the main organs that excrete fluoride. When the body absorbs fluoride in excess of the kidneys’ ability to excrete it, it will accumulate in the body and affect kidney function.

Condensed tea also contains a lot of tannic acid, which will hinder the body’s absorption of iron, manifesting as iron-deficiency anemia.


2. The water is too hot

Warm water is one of the cheapest “medicines” for the body. However, water that is too hot will damage the lining of our mouth and esophagus. The International Agency for Research on Cancer (IARC) – an agency of the World Health Organization (WHO) has listed hot water above 65 degrees Celsius as a group 2A carcinogen. Drinking hot drinks over 65 degrees will cause esophageal cancer by damaging the mucous membranes of the mouth and stomach.


3. Unboiled water

In plain water often contains many bacteria and parasites, so it needs to be boiled to destroy harmful substances in it.

If the water you drink has not been boiled, harmful bacteria and microorganisms it may contain, especially salmonella, E.Coli and Giardia. These pathogens can cause abdominal pain, diarrhea and vomiting, stomach damage…

4. Water left too long

Everyone thinks that boiled water is definitely good, but you don’t know that even if boiled water is kept for a long time, it is still not immune to contamination.

The longer the water is left, the dirtier it becomes because that is the environment for bacteria to multiply. Moreover, if water is boiled many times, it can change the natural structure of water, lose oxygen and some trace elements necessary for the body. Water should only be boiled once and should only be drunk within 24 hours.

If the above time is exceeded, families should leave to boil another amount of water. Absolutely do not store filtered water for a whole week.


5. Milk tea

When it comes to milk tea, most of the women probably really like it. Because milk tea contains sugar, flavoring … so it is very delicious and eye-catching.

However, milk tea should be added to the blacklist because it contains too much sugar.

A study published by the British Medical Journal (BMJ), conducted by French researchers, has shown an association between the consumption of sugary drinks and an increased risk of certain cancers.

What is the best drink for the body?

Warm water is the most beneficial drink for health. It is useful in quenching thirst, and at the same time can improve the body’s metabolism, accelerate the elimination of toxins and wastes from the body.


Besides, black bean water is also a drink with many meanings. Black bean juice contains a lot of selenium. Selenium plays an important role in liver enzyme function and helps to detoxify certain cancer-causing compounds in the body. In addition, selenium can prevent inflammation and reduce the rate of tumor growth. Saponins present in black beans also contribute to preventing cancer cells from multiplying and spreading throughout the body.
