BPA: BPA is a synthetic compound that can be found in many plastics and canned food packaging. BPA Is an industrial chemical used in many products. Experts believe it is important that we avoid PBA, because it is toxic to our health.
Is BPA as bad as they say?
In this article we will discuss in detail all about the BPA, including the effects it can have on health
What is BPA?
BPA (bisphenol-A) is a chemical that is used to make many commercial products such as food plastic packaging and hygiene products.
BPA was first discovered in the early l890, but was in 1950 where the chemicals found that could be mixed with other compounds to produce strong and durable plastic.
Today we can find BPA in food packaging, baby bottles and the lining of canned goods, thus avoiding breakage or corrode.
BPA can be found in the following products:
- Plastic packaged products
- canned foods
- Feminine hygiene products
- Thermal printing receipts
- CD and DVD
- household electronics
- Eyeglass lenses
- Sports team
- Dental filling sealers
It is important to note that some manufacturers have replaced the BPA bisphenol S (BPS) or bisphenol-F (BPF).
But it has been shown recently that even small concentrations of BPS and BPF can alter cells in a similar way to that BPA does . Therefore, the solution is not to eliminate only the BPA, more should be done. When you see a plastic object numbers 3 and 7, or the letters “PC” is most likely because that container contains BPA, BPF or BPS.
The alternatives to BPA out, the BPS and the BPF, but it has been found that also impact negatively on health. Important to check the packaging to see if numbered 3 and 7 or the letters “PC”.
WHERE WE CAN RECEIVE BPA?
The first place where we can receive BPA is through our diet. Specifically through the packaging of food we eat, which release BPA to food or drink, so that later comes to our body. It was found in a study that when you stop taking canned goods BPA in urine was reduced by 66% after 3 days. In another study , it was found that by dividing people into two groups, those taking fresh soup and canned soup , the canned soup had a 1,221% more BPA in urine . It also has been shown that babies who are breastfed have 8 times lower BPA levels than babies fed with milk packaged with BPA.
The main source of BPA is our diet (canned and packaged goods). Babies who drink bottled milk with BPA have higher levels of BPA in your body. BPA is bad for our health? There is controversy among experts to answer this question. Consider the effects of BPA in our bodies.
BIOLOGICAL MECHANISMS OF BPA
BPA acts in a similar way to the hormone estrogen. Because of its resemblance to this hormone, BPA can bind to estrogen receptors and influence bodily processes such as growth, cell repair, fetal development, energy levels and reproduction. Besides all this, the BPA, has the ability to interact with other hormone receptors ; such as thyroid, this causes the function of these hormones is altered.
Our body is sensitive to hormonal changes, and as the BPA is able to impact strongly direct to the hormone estrogen functions and system, small quantity of BPA it is considered to be negative for our health.
Experts believe that BPA should be banned? Many people ask this question. I must say that its use has been restricted in the European Union, Canada, China and Malaysia, on all products for young children.
There are also some US states that have done the same. Some agencies such as the FDA have said in the past that levels of BPA used in products are safe for our health. Studies say the opposite. In studies with rats they have seen negative effects of BPA at much lower than those used in the products we use in foods and beverages levels. It has also been seen in studies with monkeys, which levels equivalent to those in the products used in everyday life can adversely affect reproduction system.
The BPA has a similar structure to that of the hormone estrogen. BPA gets joining estrogen receptors and thereby affect negatively to different functions of our body.
BPA CAUSE INFERTILITY IN WOMEN AND MEN
It has been found that BPA affects fertility. In a study it conducted it was found that women with miscarriages were about 3 times more BPA in their blood than women who had successfully completed their pregnancy. It has also been found that women with higher levels of BPA have major problems in fertility treatments, thus reducing their chances of becoming pregnant.
Scientific studies have shown that men with higher levels of BPA and subjected to in vitro fertilization have up to 45 more likely to produce low quality embryos. It was also found in another study , men with higher levels of BPA were up 3-4 times more likely to have lower sperm concentration. It has also been able to verify that the Chinese men working in factories with BPA have up to 4.5 times more problems erectile difficulty and sexual satisfaction. Despite everything said up to this point, experts believe that more studies are needed.
It has been demonstrated through several studies that BPA adversely affects different aspects of women’s and men’s health.
THE NEGATIVE EFFECTS ON BABIES
It has been shown in several studies that children of mothers exposed to BPA at work weigh 0.2 kilos less than those of mothers who have not been exposed. In the case of parents exposed to BPA, it has been found that this affects the developing child. In addition, children born to mothers exposed to BPA are more hyperactive, anxious and depressed. Also it found that they were more aggressive and emotionally reactive.
It is also considered that BPA exposure in youth influences the development of prostate and breast tissue so that just increasing the risk of cancer.
Exposure to BPA during youth age has negative effect in the hormonal system development, birth weight, behaviour and risk of cancer when we are adult.
OTHER SERIOUS ILLNESS THAT CAN PRODUCE BY BPA
We also analysed studies the relationship between BPA levels and blood pressure. It found that there was between a 27 and a 135% increased risk of high blood pressure in people with high levels of BPA .
It was also found in a survey with 1455 participants, that exposure to BPA increased between 18 and 63% the risk of heart disease, and had between 21 and 60% increased risk of diabetes.
Result of later study, has shown that high levels of BPA increased the risk of developing diabetes type 2 between 68 and 130 %. It was also found of the study the participants who had higher BPA levels were 37% more likely to have insulin resistance , a key factor of metabolic syndrome and diabetes type 2.
Having high levels of BPA is related to have an increased risk of type 2 diabetes, high blood pressure and heart disease.
BPA INCREASES THE RISK OF OBESITY
A curious fact that has been proved is that obese women had BPA levels 47% higher than normal weight women. Several studies have found that participants are higher BPA levels were between 50 and 80% more likely to be obese and 59% more likely to have a larger circumference of the waist. Also highlight that not all studies support these claims.
These data on the relationship of BPA and increased obesity has also been seen in children. Although the relationship between BPA and weight gain more human studies is well supported by animal studies to confirm this missing link.
Exposure to BPA is linked to an increased risk of obesity and increased waist circumference. More studies are needed.
OTHER NEGATIVE EFECT CAUSE BY EXPOSURE TO BPA
Polycystic Ovary Syndrome: It was found that women with high levels of BPA were 46% more likely to suffer from polycystic ovary syndrome , compared with other healthy women.
Asthma: high exposures to BPA prenatally, increased the risk by 130% of wheezing in infants younger than 6 months .
Premature birth: Women with higher levels of BPA during pregnancy were 91% more likely to give birth before 37 weeks .
Liver function: High levels of BPA increased the risk by 29% to have higher levels of abnormal liver enzymes .
Immune function: High levels of BPA also impair the immune function .
Thyroid function: High levels of BPA cause abnormal thyroid hormone levels , indicating alteration of thyroid function.
Brain function: It was found that high levels of BPA in African green monkeys caused loss of connections between brain cells .
