Introduction:
Bisphenol A (BPA) are chemicals found in hard plastics and the coating of food and beverage cans. Exposure to BPA results in various health problems and conditions. BPA is associated with major health concerns such as a higher risk of cancer, reduced fertility, diabetes, and birth defects. These concerns lead to the development of BPA-free products. BPA-free plastics and products reduce these concerns by replacing bisphenol A (BPA) with alternative chemicals.
What Is BPA?
Bisphenol A (BPA) is a chemical compound used to manufacture various plastics. It is found in multiple products, such as plastic water bottles, food containers, baby bottles, eyewear, and water supply pipes. Dental sealant cement and composites also contain BPA as a component. Research shows that BPA can seep into food or beverages from containers made with BPA.
Where Is BPA Found?
Bisphenol A (BPA) can be found in:
-
Water bottles made from plastic.
-
Canned food items.
-
Plastic food packaging items.
-
Household electronic appliances.
-
Baby feeding bottles from plastic.
-
Eyewear, lenses.
-
Dental filling sealants.
-
Menstrual products.
-
DVDs and CDs.
-
Plastic Sports equipment.
Why Are Some Individuals Concerned About BPA?
Many individuals worry about BPA exposure as they can leach out of food or drink containers and into the food or beverages that they consume.
This is particularly true of foods or beverages that may be stored for longer periods in containers with BPA, such as canned tomatoes or bottled water. This will also include the plastics that may be heated, as the heat can cause additional BPA to leach out.
What Does BPA Do to Us?
BPA is soluble, and when it comes into contact with liquids or when it is heated, the bond it has formed between the plastic is broken, and BPA can seep into the contents of food or beverages. Bisphenol-A (BPA) exposure is a health concern because of its effect on infants, children, the brain, and the prostate gland of fetuses. The toxic chemicals present in the BPA can cause reproductive, immunological, and neurological problems. Increased incidence of Alzheimer's disease, metabolic disease, type 2 diabetes, childhood asthma, and cardiovascular diseases are also seen with BPA exposure.
How Could BPA Affect the Body?
Experimental studies show that bisphenol-A can produce harmful effects on different systems and organs of the body. BPA could enter the body through skin absorption, the digestive tract, and the respiratory tract. The digestive tract is considered the main area of absorption.
Important side effects of BPA:
-
Brain Function - Bisphenol-A (BPA) may affect the brain and behavior of infants and young children. It prevents chlorine removal from the cells of the central nervous system (CNS) and alters brain function and gene regulation.
-
Cancer - studies indicate that BPA exposure can increase the risk of cancer. Bisphenol A BPA can act like estrogen and other hormones and interact with certain cell receptors. It will promote the development of ovary, breast, and prostate cancer. Bisphenol-A (BPA) will also result in reducing the effectiveness of chemotherapy in breast cancer patients.
-
Infertility and Fetal Development - BPA can cause negative effects on fetal development. It can also compromise the quality of the female egg and the DNA of the fetus and can lead to birth defects. BPA adversely affects male reproductive functions and causes infertility.
-
Heart Disease and Diabetes - Studies suggest that BPA exposure can increase the risk of high blood pressure, diabetes, and heart diseases.
-
Hormone Levels - BPA mimics hormones in the body and results in abnormal hormonal levels. It interferes with the production, secretion, transport, action, and function of the body’s natural hormones.
-
Weight Problems - BPA can contribute to weight gain. It acts like a hormone inside the body and interferes with insulin production and resistance, and results in increased fat cell production.
What Does BPA-Free Mean?
BPA-free products do not contain the organic compound bisphenol A (BPA). When a product is labeled BPA- free, it means the product is somehow safer than those that are not labeled as such. BPA -free plastics are used to manufacture water bottles, food storage containers, baby dishware, toys, and baby bottles.
Are BPA-Free Products Safe?
BPA-free products have replaced BPA with bisphenol-s (BPS) or bisphenol-F (BPF). These chemicals are almost similar in function and structure to bisphenol-A (BPA). The side effects of these newly used chemicals have not yet been studied heavily. Some studies suggest that they also may leach into food and disrupt cell function in ways similar to BPA. Thus, using bisphenol-A-free (BPA-free) plastics is not a permanent solution. Limiting the use of plastic or completely avoiding it for the storage of foods and beverages will be a better solution.
What Are the Steps to Reduce BPA Exposure?
-
Use BPA-Free Products: Try to use BPA-free products as much as possible. If a product is not labeled BPA-free, remember that plastics marked recycle code 3 or 7 contain BPA.
-
Swap plastic water bottles for glass or stainless steel.
-
Swap plastic lunch boxes or food storage containers for glass, ceramic, or stainless steel.
-
Use plastic-free feminine hygiene products.
-
Use safer reusable natural food wraps such as organic cotton.
-
Avoid consuming food in cans as much as possible and try to use fresh instead. They often contain a plastic lining that can leach into food and cause toxic side effects.
-
Avoid using plastic containers in the microwave. Heating food in plastic containers results in the leaching of chemicals into the food.
-
Avoid storing food in plastic containers.
-
Opt for plastic-free baby bottles, toys, and other products.
-
Try to purchase plastic-free toys; look for non-toxic wooden toys.
Conclusion:
BPA-free plastics and products are introduced to reduce the adverse effects caused by plastics containing the harmful chemical bisphenol-A (BPA). Plastic products labeled BPA-free may contain substitutes (bisphenol-F, bisphenol-S, and bisphenol-B) that are chemically similar to BPA. These chemicals may also have similar harmful effects as bisphenol-A (BPA) but at lower levels. Bisphenol-A (BPA)- free labeled products cannot be considered completely safe because of their structural similarities with BPA. One of the best methods to avoid the harmful effects of BPA is to reduce the use of plastic products and switch to natural alternatives and other substitutes like stainless steel bottles, utensils, and borosilicate bottles.
