The Bisphenol A (BPA) is a chemical compound widely used in
the manufacture of plastics. Therefore, it can be present in plates, bottles, bottles,
pacifiers, toys, etc. since it would need a high amount to cause damage.
BPA (Bisphenol-A) is a chemical that is added to many
commercial products, including food containers and hygiene products. It was
discovered for the first time in 1890, but in 1950, chemists realized that it
could be mixed with other compounds to produce strong and resistant
polycarbonate plastics. Currently, BPA plastic containers are commonly used in
food containers, baby bottles and other things. PA is also used to make epoxyresins, which are put on the inner line of food container cans to prevent the
metal from corroding and cracking.
Truths and conjectures about BPA
- It is known with certainty that:
- 95% of human beings present BPA in the urine.
- BPA is harmful to health and to the environment.
- It is not known exactly what is the maximum dose of BPA that can be considered as having no adverse effects on health. Especially in the long term.
- PVC, epoxy resins (present in interior coatings of can and soda cans) and many polycarbonates, have BPA.
Plastics that are often reused, with scratches, etc., release
more BPA.
The temperature and the acidity of the foods favor the
migration of BPA.
Many experts say that BPA is harmful, but others do not
agree.
Biological Mechanisms of BPA.
It is said that BPA mimics the structure and function of the hormone called estrogen.
Because of its estrogen-like conformation, BPA can bind to
estrogen receptors and influence body processes, such as growth, cell repair,
fetal development, energy levels and reproduction.
In addition, BPA may also can interact with other hormone
receptors, such as thyroid hormone receptors, and, consequently, alter their
function.
Your body is sensitive to changes in hormone levels, which
is the reason why it is believed that BPA's ability to mimic estrogen can
damage your health.
Currently BPA is everywhere (air, water, etc.) in small
quantities. Enough so that modern ultra-trace analytical methods can detect them.
If you worried about BPA while taking food or drinking its better to take water
from water bottle with filter and BPA free Materials. problem is not the
presence of BPA in certain plastics, but when these plastics are in contact
with food, part of the BPA can pass to them, then be ingested by humans or
animals and move to the environment. It is what is called migration.
Possible migrations that can occur: to bottled water in
plastic containers, to water heated in water heaters made of plastic, to food
stored in plastic bags and containers, either in the refrigerator, or when
heating them with a microwave or freezing them, etc.
