A third example is the organs of the female reproductive tract, where BPA induces adverse effects on the uterine epithelium (92) and ovary. In fact, numerous studies have shown that BPA alters follicle maturation and meiosis in oocytes, disrupts steroidogenesis, and reduces oocyte quality (77, 93, 94).
In vitro and animal toxicological studies have consistently reported a potential for decreased female fertility resulting from BPA exposure due to disruption in oocyte maturation, decreased ovarian E2 synthesis, and early pregnancy loss [48-51].
Researchers have linked BPA to developmental and health problems in children, including learning and behavior conditions like Attention Deficit Hyperactive Disorder (ADHD), anxiety and depression; early puberty in girls; diabetes; obesity; and heart disease.
BPA exerts endocrine disruptor action due to its weak binding affinity for the estrogen receptors ERα and ERβ. BPA exerts other effects by activating the membrane receptor GPER (GPR30) and/or other receptors such as the estrogen-related receptors (ERRs).
In a cohort study by Mustieles et al. (2019) [46], involving 298 children aged 9 to 11, BPA was observed to increase the risk of obesity, particularly abdominal obesity, in peripubertal children.
Drinking sufficient water is essential to flushing out toxins such as BPA. A good rule of thumb is to drink half your body weight in ounces each day (for example, if you weigh 150 pounds, you should aim to drink 75 ounces of water a day).
Obesogens are generally defined as chemicals that can cause the human (and animal) body to produce more fat than it normally would. Obesogens can include substances we often think of as fattening, like sugars, but also include an array of chemicals used in all sorts of products, such as BPA, phthalates and more.
Studies in rodents show that high oral doses of BPA may affect: fetal, infant and pubertal development, male and female reproductive organs and functions, and. organs such as the liver, kidney and thyroid.
International Regulation
Austria banned BPA in pacifiers and teething devices. France banned the use of BPA in all food containers as of 2015 and infant food packaging as of 2013. Before this, several French cities banned baby bottles made with BPA in city nurseries and daycare centers.
In addition to regulating the menstrual cycle, estrogen affects the reproductive tract, the urinary tract, the heart and blood vessels, bones, breasts, skin, hair, mucous membranes, pelvic muscles, and the brain.
Much of the BPA in our bodies is metabolized by the liver and exits through urine. Most studies indicate that BPA is broken down quickly, usually in a matter of hours.
People with BPD are often on edge. They have high distress and anger levels, so they may be easily offended. They struggle with beliefs and thoughts about themselves and others, which can cause distress in many areas of their lives. People living with BPD often have an intense fear of instability and abandonment.
The concentrations of BPA by food types ranged from 5.88–21.3 ng/g in canned beef, 2.94–6.36 ng/g in canned chicken, 0.78–7.85 ng/g in frozen fish, 2.28–9.40 ng/g in dried fish, 1.66–26.3 ng/g in canned fish, 1.20–17.5 ng/g in crayfish, 1.45–3.43 ng/g in processed cheese, 0.20–4.80 ng/g in canned evaporated milk, 0.41– ...
How does Bisphenol A harm health? BPA is classified as a hazardous chemical in the EU due to its ability to damage fertility, and cause serious eye damage, allergic skin reactions and respiratory irritation. In addition, BPA is an endocrine disruptor that can disrupt the normal functioning of the hormone system.
BPA tends to affect various pathways like the insulin pathway, glucose pathway, lipid metabolism, protein metabolism, and ovarian steroidogenesis, thereby having the potential to cause metabolic-endocrine disorders like PCOS in premenopausal women.
In conclusion, it can be concluded that exposure to BPA during infancy increases the risk of precocious onset of peripheral puberty and the reduction of female reproductive fertility after puberty.
In females, high exposure to BPA affects the levels of estradiol (E2), which in turn causes irregular hormone balance and other metabolic abnormalities, e.g. early puberty, menstrual irregularities, increased risk of endometriosis as well as being at higher risk of embryo implantation failure [82].
BPA is found in:
Hard polycarbonate plastic in a variety of items, such as: Some kitchenware, like plates, mugs, and storage bottles.
BPA is an endocrine disruptor . The Environmental Protection Agency (EPA) notes that BPA can imitate the body's hormones and interfere with the production of, response to, or action of natural hormones. For example, it can behave in a similar way to estrogen and other hormones in the human body.
The primary source of exposure to BPA for most people is through the diet. While air, dust, and water are other possible sources of exposure, BPA in food and beverages accounts for the majority of daily human exposure.
Clothing containing a polyester/spandex blend, common in athletic wear, contains BPA, whereas traditional cotton clothing does not. Using flourospectroscopy, the presence of BPA in these types of clothing was confirmed, as well as measured over time.
Energy-rich foods: Energy-dense foods fuel your body and can help you put on pounds in a healthy way. These include nuts (especially almonds, walnuts, peanuts), dried fruits (raisins or prunes), dark chocolate, high-fat dairy (milk), and certain vegetables (potatoes and yams).
Soda, juices, Kool-Aid™ and many sport drinks have NO nutritional value but are high in calories, and consuming too many calories can cause weight gain. Sugary drinks do not fill you up as quickly as solid foods do, so it is easy to take in more calories than you really need.
