Can you put coffee in a plastic cup?

In this article, we will provide the answer to the question: “Can you put coffee in a plastic cup?”. In addition, we will discuss the health effects of drinking hot coffee in a plastic cup and the relations between plastic cups and the environment.

Can you put coffee in a plastic cup?

No, you cannot put coffee in a plastic cup. It’s not safe to drink coffee in a plastic cup. Weight gain, development of some types of cancer, tiredness, drowsiness, frequent headaches, hyperactivity or aggression, alteration in child growth and early sexual maturation are some of the consequences of drinking hot coffee in a plastic cup.

The amount of styrene present in disposable cups is “partially” above that recommended. When subjected to the heat of coffee, for example, this substance, which is toxic, is released and can be ingested at the time the coffee is drunk.

The amount of styrene released by the cups, in 10 minutes of contact, is around 13.6 and 49.3ng/ml-I. The constraint is 20ng/ml-I.

In addition to styrene, the plastic present in plastic utensils and in the inner lining of food and beverage packages releases, especially when heated, a substance called bisphenol A. Bisphenol is a toxin that migrates to food and can then be ingested.

What is the plastic cup made of?

Plastic cup is made with different materials, depending on its application, but both cups and straws are made with a variety that uses Bisphenol A (BPA) in its composition. According to Omilights, tests show that 95% of people who consumed hot drinks in plastic cups had high concentrations of BPA in urine tests.

You’ve probably already had something hot from a plastic cup, but maybe it’s time to review this behavior if it’s frequent. After all, Bisphenol A is associated with a multitude of problems, such as decreased immunity, obesity, infertility and hormonal imbalances.

To identify the type of plastic used in the manufacture of a particular object, there is a code marking that is easily identified. The triangle-shaped arrows show that it is recyclable, with the number inside the symbol indicating the type of material used in its manufacture.

Each one has specific characteristics, but, as we are talking about temperature and release of toxic elements, it is good to remember that the marking with the number 5 or “PP” means that polypropylene was used, a material that can be taken to the microwave without risks, as it releases a tiny amount of chemical compounds when heated.

The use of polycarbonate, which uses BPA in its composition, is indicated by the number 7. When not subjected to high temperatures, the material is safe; on the other hand, when exposed to heat, it releases chemical compounds that can be harmful to our health. Now, you already know: when having a coffee outside the house, always check the type of cup, for the sake of your health.

What is the relationship of coffee in a plastic cup with the environment?

Coffee in a plastic cup is prejudicial for the environment. The disposal of plastic cups in the environment causes pollution and release of substances into the soil.

Plastic cups can be very practical and hygienic, but their indiscriminate use ends up generating an amount of waste that could easily be avoided, especially in offices, where people spend most of the day. 

As if the issue of waste was not enough for an ecological choice, know that containers can also release toxic substances when subjected to high temperatures.

Global warming is an increase in the temperature of the Earth’s surfaces caused by the concentration of greenhouse gas, which traps the heat emitted by the Sun around the planet.

Despite being a natural and important process for the survival of human beings, some harmful actions, such as deforestation, burning and emission of polluting gas by industries, are helping in this warming process that can be felt in different parts of the world.

But there are some actions that each individual can do to contribute to this negative effect, and one of them is the moderate use of some everyday products, such as plastic and disposable cups.

Should I avoid drinking hot coffee in plastic cups?

Yes, you should avoid drinking hot coffee or other hot substances in plastic cups. Also, do not heat food or drinks in plastic containers, especially in the microwave.

You should also avoid the use of plastic as packaging, restricting this use only to fresh fruits and vegetables. Liquids such as milk, juices and water must be kept in glass or stainless steel bottles. 

In addition to avoiding plastic, the diet must be balanced, rich in natural products and with as few industrialized products as possible, avoiding contact with bisphenol A and other toxins. 

In addition, vitamins and minerals present in fruits, vegetables and nuts support the liver detoxification systems, a process that takes place in the liver to eliminate foreign and toxic substances from the body.

Maintain a balanced diet, avoid smoking and practice physical activity, the pillars for a healthy and long life.
