Plastic bottles cause hundreds of harmful and unknown chemicals in water

Plastic bottles are harmful

If someone felt a taste associated with plastics while drinking water from a plastic bottle, there could be a specific reason for it, note chemists from the University of Copenhagen. 

We were surprised by the large amount of chemicals found in the water after keeping it in the bottle for 24 hours. Hundreds of substances were present there, including some that had never been detected in plastic before, as well as compounds that are potentially harmful to health. After washing the bottle in the dishwasher, there were thousands of substances.
– reports prof. Jan H. Christensen, one of the authors of the publication that appeared in the Journal of Hazardous Materials.

Approx. 400 substances came from the bottles alone, and over 3.5 thousand. from detergent cubes used in dishwashers . A significant proportion of these compounds are yet to be identified, and a toxicity of 70% is unknown. already defined relationships.

Researchers are worried, for example, by the presence of the so-called photoinitiators, which have the potential to interfere with hormones and promote cancer. 

Scientists also found plastic softeners, antioxidants and other manufacturing compounds. Some of the compounds may come from changing substances in the bottle into other substances. Scientists have discovered, for example, DEET – an insect repellent . This substance could have arisen from the decomposition of one of the plastic softening additives.

Even with known substances specifically added to plastics, the toxicity of only a small fraction of them has been studied. So consumers do not know if the other compounds are harmful to their health.
– emphasizes the co-author of the work, Selina Tisler.

In experiments, the Danish team reconstructed the way most people use plastic bottles – they left tap water in new and used bottles for 24 hours before and after washing in the dishwasher.

In addition to the compounds present in the detergent, more substances from plastics were released into the water after washing. Probably because the operation of the dishwasher helped to release them. 

We all make sure that our drinking water is pesticide-free. However, when we pour water into containers from which we drink, we are effectively introducing hundreds or thousands of compounds into it. While we cannot yet say if they are harmful, I will personally use a glass or steel bottle.
– says prof. Christensen.

Researchers suspect that the manufacturers deliberately add only a small fraction of the compounds detected. Most of them could have got into the bottles unintentionally, during production or formed during chemical changes, as happened with the already mentioned DEET.

According to the researchers, the obtained results reflect both gaps in knowledge and in legal regulations.

This study shows how little information we have about chemicals permeating from objects in contact with our beverages and food. It is a general problem that the regulation of concentration measurements during production lags behind. Fortunately, both in Denmark and in various centers around the world, ways are being sought to better regulate this area.
– emphasizes prof. Christensen.

Chemists are counting on manufacturers to take greater responsibility themselves now.

Hopefully, companies that put their names on reusable plastic bottles will be more careful about the products they order from vendors. Perhaps they will start to impose greater requirements on them regarding the testing of substances in their articles.
– says Selina Tisler.


Vitamin D3 – “natural antibiotic” increases immunity

Vitamin D3 is essential for the immunity, growth of young children, and for healthy bones and teeth. The primary source of this vitamin is skin exposure to UVB radiation.The correct value should be between 30-50 ng / mL.

The importance of vitamin D and immunity

The seasons change, autumn is coming along with winter and lower temperatures. The body has to get used to the new conditions and the immune system becomes weakened. During weakness, we are attacked by viruses, bacteria and fungi, which favors various infections. Adequate level of vitamin D is a very important element in the fight against microorganisms. We should ensure the high level of the sun vitamin already in the summer by spending a lot of time outside. Supplementation of this vitamin is important in winter. 

  • 0-6 months : 400 IU / day, regardless of the feeding method; 
  • 6-12 months : 400-600 IU / day depending on the daily dose of vitamin D taken with food
  • Children (1-10 years): 600-1000 IU / day
  • Youth (11-18 years): 800-2000 IU / day;
  • Adults (19-65 years): 800-2000 IU / day
  • Seniors (> 65-75 years old) and people with dark skin: 800-2000 IU / day
  • Seniors (> 75 years of age): due to the reduced efficiency of skin synthesis, possibly reduced absorption from the gastrointestinal tract and altered metabolism of vitamin D, supplementation is recommended throughout the year at a dose of 2000-4000 IU
  • Pregnant and lactating women: 2000 IU / day. However, it is best to test your vitamin D levels before introducing supplementation. Supplementation should be carried out under the control of serum 25 (OH) D in order to obtain the optimal concentration in the range of> 30-50 ng / ml

The most common effects of vitamin sun deficiency include: 

  • rickets in children
  • osteopenia and osteoporosis
  • increased risk of bone fractures
  • secondary hyperparathyroidism
  • neuromuscular disorders
  • hair loss

The association of low vitamin D levels with the development of cancer, cardiovascular diseases, autoimmune diseases, and depression is also increasingly discussed. In addition, children may develop irritability, developmental delay, and frequent viral and bacterial infections. 

10 symptoms of vitamin D3 deficiency

Fractures, bone pain

Deficiencies of this vitamin lead to disturbances in the calcium and phosphate balance, which results in abnormal bone mineralization. In children, the absorption of calcium may then be reduced and bone growth may be impaired and, consequently, rickets. In adults, reducing bone mineralization is called osteomalacia. 

Vitamin D3 deficiency also leads to osteoporosis, i.e. pathological reduction of bone mass and, consequently, an increased number of bone fractures and injuries. 

Muscle aches

Vitamin D3 deficiency can also lead to abnormalities in muscle building , resulting in muscle aches. The sun vitamin is very necessary for the reconstruction of muscle tissue, as it is involved in regeneration, e.g. after exercise. Constant muscle pain may be caused by an abnormal vitamin D3 value in the body.

Deterioration of the skin condition

Vitamin D is involved in the synthesis of substances that regenerate the epidermis and dermis after injuries. A deficiency of this vitamin can lead to a disturbance in wound healing. 

Caries and gum problems

Vitamin deficiencies often manifest themselves in the slow healing of the gums and problems with the regeneration of the oral mucosa . The deficiency of this vitamin is also tooth decay.

Fatigue, apathy

A low amount of vitamins in the body can also manifest itself in physical exhaustion and constant fatigue. Additionally, apathy may appear, reluctance to perform basic activities, fatigue and shortness of breath.

Sleep disturbance

The right amount of this vitamin also affects the quality and amount of sleep. Vitamin is best taken in the morning as it stimulates the body and reduces fatigue

Reduced immunity

Supplementation increases the body’s resistance. In the case of deficiencies, there is an increased susceptibility of the body to infections and frequent colds . 

Hair loss

Deficiencies also affect skin appendages, such as hair and nails. Deficiencies disrupt the hair’s life cycle, leading to hair loss.

Mood disorders

The research shows that it has an impact on the mood on a given day. Vitamin D3 is involved in the synthesis of serotonin and dopamine, and the hormones that affect mood.

Vision disturbance

Vitamin deficiency of the sun can manifest itself in: hyperemia , dry eye or excessive tearing.

Aphelion phenomenon : Social media posts based on misinformation have caused concern to millions of people

Since the beginning of July, Facebook posts and tweets as well as other social media posts as well as WhatsApp messages have been spreading the word that the weather will be cold all over the world from July 4 to August 22 and people may get sick during this time. And their throats will be sore.


Fibrous foods can reduce antibiotic resistance

Research has now shown that fiber-rich foods cause changes in the gastrointestinal tract that reduce the risk of antibiotics becoming less effective.
