What is BPA and why is it bad for you?

In a health conscious world everyone seems to be talking about BPA and why BPA should be avoided. Our stainless steel water bottles are 100% BPA-free. But what does that mean? What is BPA and what are the health risk associated with BPA?

What is BPA?

BPA stands for bisphenol A. It’s an industrial chemical that’s been used since the late 1950s to make certain plastics and resins.

BPA-based plastic is both clear and tough which makes it the perfect material to make water bottles.

 

What happens when you drink from a BPA-based water bottle?

When water bottles are made from BPA, sometimes not all of the BPA gets sealed. Once water is added the BPA can mix in with the liquid and you’ll end up drinking it.

 

The health effects of BPA on your body

Hormones

Scientific research suggests that BPA mimics the structure and function of the female hormone Oestrogen. This allows it to bind to Oestrogen receptors and influence your body’s processes such as growth, energy levels, cell repair and reproduction. 

BPA can also interact with other hormone receptors, such as thyroid hormone receptors, and influence their functions too.

 

Fertility

It’s thought that BPA can negatively affect fertility for both men and women.

Tests carried out on women going through fertility treatments showed that women with higher levels of BPA had proportionally lower egg production and were up to 2 times less likely to become pregnant.

Another scientific study found that women who had frequent miscarriages had almost 3 times as much BPA in their blood than women who carried to full term. 

It was also found that men with high level of BPA were 3-4 times more likely to have both low sperm concentration and a low sperm count.

Whilst couples who were undergoing in-vitro fertilization (IVF) found that men with higher levels of BPA were 30–46% more likely to produce lower-quality embryos.

To top it off, women with high levels of BPA during their pregnancy were 91% more likely to deliver before 37 weeks.

 

Babies

Unfortunately, it’s been found that babies can experience negative health effects simply due to their mothers having high levels of BPA in their body.

Research shows that newborn babies born to mothers that have been exposed to BPA weigh up to 0.2kg less than babies who come from mothers who haven’t been exposed to BPA at work. These babies also tend to have a shorter anogenital distance, and can be more hyperactive, anxious and depressed.

It’s also thought that babies who are exposed to BPA have an increased risk of cancer due to BPA influencing the development of prostate and breast tissue. 

In addition to this, the World Health Organization (WHO) reported that the BPA levels measured in breastfed babies were up to 8 times lower than babies who were fed from BPA-containing bottles.

Asthma has also been linked to BPA. Pregnant women who had exposure to BPA, particularly at week 16, were 130% more likely to give birth to babies who would experience wheezing. Infants who were exposed to BPA could also develop asthma in later childhood.

 

Heart disease and type 2 diabetes

Scientific studies have shown that for individuals with high levels of BPA, they have a 27% - 135% greater risk of high blood pressure and a 68% - 130% higher risk of developing type 2 diabetes.

Those with the highest levels of BPA in their body were found to have an18-63% greater risk of heart disease, a 21-60% greater risk of diabetes, and a 37% greater chance of having an insulin resistance. 

A follow-up study also revealed that people with higher levels of BPA in their body had a 68-130% higher risk of developing type 2 diabetes. 

 

Risk of obesity

It’s been found that obese women tend to have 47% higher BPA levels in their body.

Other studies have shown that people with high BPA levels are 50–85% more likely to be obese and 59% more likely to have a large waist circumference. 

Similar patterns linking high levels of BPA and obesity have also been found in children and teenagers.

 

What can you use instead of a BPA-based water bottle?

Should you worry about BPA? As you can see it’s a good idea to avoid exposing your body to BPA where possible. It’s particularly important to go BPA-free as much as you can if you’re pregnant, especially in the early stages of your pregnancy.

Luckily swapping your plastic water bottle to a BPA-free one is both easy and cheap and your body will thank you in the long run.
