This statement is not scientific. Although the materials used to make stainless steel electric kettles contain manganese, it does not exist in the form of a single element and is difficult to dissolve in daily boiling water.

Even if it is boiled repeatedly for more than 1000 hours, manganese can indeed be precipitated, but the amount of manganese that enters the water in the form of ions is extremely small, and its impact on the human body is basically negligible. There is no risk of disease. However, the prerequisite is to purchase regular products that meet national standards.

The 3 types of water you should really drink less

1. Extra hot water:

Frequent consumption of extremely hot food and hot drinks may pose health risks.

For example, hot drinks or food at 65℃ or above will increase the risk of esophageal cancer. This is because overheated food will cause physical damage to the esophageal mucosa in the esophagus. Once the mucosa is damaged, gastric acid reflux will also irritate the damaged area. This repeated damage and irritation can easily lead to cell canceration, increasing the risk of esophageal cancer.

2. Raw water:

Raw water that has not been boiled or treated with effective measures may contain bacteria and various microorganisms that are harmful to human health. It may pose a potential threat to health and may easily lead to acute gastroenteritis and some infectious diseases.

3. The water in the water dispenser has not been cleaned for a long time:

Most water dispensers use bottled water, which is safe and hygienic as long as the quality is up to standard.

Compared with the water, the water dispenser itself needs more attention. This is because the water dispenser may breed bacteria during use. If it is not cleaned for a long time, there will be safety risks. It is recommended to clean the water dispenser every 1 to 2 months.
