We generally replenish the loss of body fluids by drinking water. Office workers often use plastic cups for drinking water. Experts suggest that from a health perspective, besides ceramic cups, other cups are not very healthy.
3 Types of Cups for Drinking Water That May Cause Cancer
1. Disposable Paper Cups May Harbor Potential Carcinogens
Disposable paper cups may seem hygienic and convenient, but it's difficult to judge their qualification rate or whether they are clean and sanitary with the naked eye. From an environmental perspective, disposable paper cups should be used as little as possible. Some manufacturers add large amounts of fluorescent brighteners to make the cups look whiter. It is this fluorescent substance that can cause cells to mutate and become a potential carcinogen once it enters the human body. Secondly, unqualified paper cups are often very soft and can deform easily when filled with water. Some have poor sealing, causing the bottom to leak easily, which can easily lead to scalding from hot water. Even worse, when you gently touch the inside of a paper cup, you can feel a fine powder on it, and the area touched by your fingers turns white, which is a sign of a low-quality paper cup.
2. Metal Cups Can Leach When Drinking Coffee
Metal cups, such as those made of stainless steel, are more expensive than ceramic cups. The metal elements in enamel cups are generally stable under normal conditions, but they can leach out in acidic environments, making them unsafe for drinking acidic beverages like coffee and orange juice.
3. Plastic Cups Are Most Likely to Harbor Dirt and Bacteria
Plastic cups should also be unpopular. Because plastic often contains plasticizers, which include some toxic chemicals, when hot or boiling water is placed in a plastic cup, these toxic chemicals can easily leach into the water. Moreover, the internal microscopic structure of plastic has many pores that hide dirt, and if not cleaned thoroughly, bacteria can easily grow. Therefore, when choosing a plastic cup, be sure to select one made of food-grade plastic that meets national standards.
The Safest Cups for Drinking Water:
1. Glass Cups
Among all materials, glass cups are the healthiest. During the manufacturing process, glass cups do not contain organic chemicals. When people drink water or other beverages from a glass cup, they don't have to worry about ingesting chemicals. Additionally, the glass surface is smooth and easy to clean, making it difficult for bacteria and dirt to breed on the walls. Therefore, drinking from a glass cup is the healthiest and safest option.
However, although glass cups are chemical-free and easy to clean, their strong thermal conductivity can easily cause users to burn themselves accidentally. If the water temperature is too high, it may also cause the cup to burst, so it's best to avoid filling them with very hot water.
2. Ceramic Cups Without Glazed Coating
The best choice for drinking water is a ceramic cup without a glazed coating, especially one with a colorless interior. It is not only safe in material and can withstand high temperatures but also has relatively good heat retention, making it a good choice for drinking hot water or tea.
Therefore, for the sake of health, it's important to choose the right cup for drinking water and be aware of the potential health hazards from cups.
Extension: Eight out of Ten People Don't Clean Their Cups Properly; Cleaning the Bottom is Important
Cups are used by everyone every day, but do you clean them daily? What are the key points to focus on when cleaning, and what is the best cleaning agent to use? These seemingly simple questions are closely related to health.
If possible, it's best to clean the cup immediately after each use. If that's too much trouble, it should be cleaned at least once a day, preferably washed before bed and then air-dried. When cleaning a cup, not only the rim should be cleaned, but the bottom and walls should not be overlooked, especially the bottom, which is not often cleaned and may accumulate a lot of bacteria and dirt. Professors especially remind women that lipstick contains chemical components and is highly likely to adsorb harmful substances and pathogens from the air. When drinking, these harmful substances can be introduced into the body, so any residual lipstick on the rim of the cup must be thoroughly cleaned. Simply rinsing with water is not enough when cleaning a cup; it's best to use a brush. Also, because the main ingredient of dishwashing detergent is a chemical synthetic agent, it should be used with caution, and be sure to rinse it off thoroughly with clean water. To clean cups with a lot of grease, dirt, or tea stains, you can squeeze some toothpaste on a brush and scrub it back and forth inside the cup. Toothpaste contains both a cleaning agent and very fine abrasives, which can easily remove residue without damaging the cup.
