Using these 3 cups to drink water is like 'poisoning yourself'

Water makes up 70-80% of body weight. Water has the ability to provide a source of minerals, transport nutrients and oxygen necessary for cells, and nourish cells in all activities of the body.

Water in the body has the effect of regulating body temperature balance at 37 degrees Celsius, our body temperature will automatically adjust when the weather changes hot and cold thanks to water. Water converts food into energy, helps eliminate toxins and waste products that cannot be absorbed by the body through urine and feces. Water also lubricates joints, helps joints work smoothly, smoothly and avoid injury.

So drinking enough water is extremely important. However, besides that, we also need to pay attention to the choice of drinking glasses. Regularly drinking water in cups with unsafe materials is no different from using 'chronic poisons', people must be careful, especially the following types of cups:

Disposable paper cups

Disposable paper cups are convenient, but they are not safe for the environment and health.

Disposable paper cups are not safe for the environment and health.

The team of researchers from the Indian Institute of Technology, Kharagpur said that sipping hot drinks from paper cups can lead to the ingestion of contaminants such as tiny plastic particles, harmful ions, metals, and other contaminants. severe. increases the risk of reproductive defects, cancer, and even neurological disorders.

To get the above conclusion, scientists tested pouring hot ultrapure water into 100ml paper cups. After 15 minutes, they added a special drug to detect and quantify plastic particles in the collected water sample. Scientists have discovered about 25,000 small plastic particles in hot water. This includes heavy metals such as lead, chromium, cadmium and arsenic.

In addition, some paper cup manufacturers add bulk fluorescent whiteners to make the cups appear whiter. It is this type of fluorescent substance that, when entering the body, can cause cell mutations and is a potential carcinogen.

Besides, poor quality paper cups are often soft and easily deformed after pouring water in. Some types of paper cups have absorbent bottoms, which can easily burn your hands when hot water is poured into the cup. In particular, there are paper cups that when touching the inside of the cup, we can easily feel the powder in them, sometimes this white powder also sticks to the fingertips, these are the cups. Typical low quality paper should not be used.

Cups made of recycled plastic

Not all plastic bottles and cups can be used for hot water. Some plastics are very unstable at high temperatures and can release substances harmful to the body, such as bisphenol A (BPA) and phthalic acid, so using hot drinking plastic cups is not good for health. strong.

Colorful mugs

Using multicolored cups carries the risk of heavy metal poisoning. (Illustration).

We often like to use cups with many eye-catching colors, but in fact these coloring materials contain many potential dangers, especially they contain polish on the textured surface. . When using these cups to drink water or drink highly acidic or alkaline beverages, the lead as well as the heavy metal elements present in these colors will be dissolved, so when drinking the Water containing this chemical will be harmful to health.

Choosing the right drinking cup

Notice the color

Although colorful cups look very eye-catching, these patterns are painted with paints and are not safe to drink hot water. Therefore, it is best to choose a cup with a white inner cup.

Pay attention to the symbols when using plastic cups

Plastic cups can be made from many different materials. The key difference is how toxic the plastic they are made of is. Each type of plastic is indicated by a letter or number, usually located between a triangle with arrows and can be found on the shell or the bottom of the plastic cup.

These symbols contain important information because each type of plastic contains chemicals that can cause many different levels of harm to our health.

Below is a summary of 7 commonly used plastics and their symbolic meanings.

PET aka PETE

PET (short for polyethylene terephthalate) is one of the most commonly used plastics for household products, such as mineral water bottles, soft drinks, beer and packaging.

This is a label for a single-use plastic, so repeated use can increase the risk of dissolving the heavy metals and chemicals that make up them. These substances affect the hormonal balance in the body.

PET plastic is difficult to clean, their recycling level is also very low (only about 20%) so it is best to throw them away immediately after use.

HDP or HDPE

HDP (high density polyethylene) is a plastic used to make hard plastic containers such as milk jugs, detergent bottles, cooking oils, toys, and some plastic bags. This type of plastic does not emit any harmful substances, so experts often recommend choosing HDP bottles when buying because they are considered the safest of all.

PVC or 3V

PVC is a soft and flexible plastic used to make transparent food packaging, cooking oil bottles, toys and many other products. PVC is quite common, but they contain 2 harmful chemicals that affect the body's hormones. This substance can release toxins at high temperatures, so it is only allowed to store food or drinks below 81 degrees Celsius.

LDPE

LDPE is a low-density thermoplastic commonly found in noodle boxes, freezer boxes, grocery bags, and pie crusts. Products containing this substance will not be able to heat in a microwave oven, avoid high temperatures because it will release chemicals.

PP

PP (polypropylene) is a white or almost transparent plastic used to make yogurt, syrup, or coffee cups. This substance is durable and lightweight, withstands temperatures of 167 degrees Celsius, so it can be reused, rotated in the microwave. PP is also very resistant to moisture and grease.

PS

PS, or polystyrene, is a cheap and lightweight plastic that can be found on the shells of some snack containers, drinking cups, egg cartons, and picnic knives and forks. Although they are remarkably resistant to heat and cold, at high temperatures such as microwaves they can release toxic substances. In addition, it is also not allowed to store items with strong acids and strong alkalis. Therefore, this type of plastic is not allowed to be used for long-term food and drink storage.

PC or without the symbol

This type of plastic can be used to make 3 - 5 liter water containers or cans and some food products. Is the most dangerous plastic, easy to produce carcinogens, BPA.

Prioritize choosing glass cups, porcelain cups without coloring

Drinking water from a glass is the best and safest for health.

Glass and uncolored porcelain cups are the two safest cups to use. The glass beaker does not contain organic chemicals during the firing process. Moreover, the glass surface is smooth and easy to clean. Bacteria and dirt do not easily breed on the wall of the cup, so drinking from a glass cup is the best and safest for health.

In addition, unglazed, uncolored porcelain cups are also safe cups and retain heat well. Therefore, when you want to drink hot drinks or tea, you should choose this cup.
