How to identify BPA-free plastics
It is important to identify BPA-free plastics to minimise the risk of ingesting Bisphenol A (BPA), an industrial chemical used in the manufacture of plastics. While the U.S. Food and Drug Administration (FDA) has stated that BPA is safe at low levels, it may be harmful at higher levels, and it is always better to be cautious. Here are some ways to identify if a plastic item is BPA-free:
Firstly, check the opacity of the plastic. Opaque plastics are often BPA-free, so if you can't see through it, that's a good sign. However, for clear or clear-tinted plastics, further investigation is needed. Look for a recycling number, usually stamped on the bottom of the container. Numbers 1 to 6 indicate that the plastic is BPA-free, while number 7 suggests the possible presence of BPA.
Additionally, pay attention to labels. Containers marked as ""unbreakable" or "microwave-safe" are more likely to contain BPA. On the other hand, if a container is labelled "handwash only," it is probably made of acrylic and is BPA-free. For older containers without a recycling number, especially those purchased before 2012, it is advisable to assume they contain BPA and dispose of them properly.
It is also important to consider the condition of your plastic containers. Worn, scratched, or damaged containers pose a higher risk of leaching chemicals into your food. Avoid storing acidic foods, such as tomato sauce, in plastic, as the acidity can draw chemicals into the food. Similarly, avoid placing hot foods in plastic containers and exposing them to high temperatures, including the dishwasher, as this can increase the likelihood of chemical leaching.
Finally, when in doubt, opt for glass or BPA-free alternatives. Glass containers do not carry the same risks as plastic and are a safer option for food storage.

Health risks of BPA exposure
Bisphenol A (BPA) is an organic synthetic compound used to make polycarbonate plastic, which is commonly used in food and drink packaging, medical devices, thermal paper, and dental materials. While the potential health risks of BPA exposure have been widely debated, with some studies reporting mixed results, there are several concerns about its effects on human health.
One of the primary concerns regarding BPA exposure is its potential impact on hormone levels. Some experts believe that BPA can act like a hormone in the body, disrupting normal hormone levels and development, particularly in fetuses, infants, and children. BPA has been shown to interfere with thyroid hormones and sex hormone receptors, including estrogen and androgen receptors. This interference can have deleterious effects on physiological functions and increase the risk of certain diseases. Animal studies have also linked high levels of BPA exposure to infertility, with evidence suggesting that it can impair male reproductive function and sperm motility.
BPA exposure has also been associated with an increased risk of various health conditions, including obesity, diabetes, attention deficit hyperactivity disorder (ADHD), heart disease, and high blood pressure. While the evidence for these links is not yet conclusive, studies in animals have shown a correlation between BPA exposure and these health problems. Additionally, BPA's ability to impair glucose homeostasis and insulin resistance has been observed, indicating a potential contribution to the development of Type 2 diabetes.
The effects of BPA exposure on the brain and behaviour have also raised concerns. The National Toxicology Program at the FDA has expressed concern about the safety of BPA for children and infants, suggesting possible effects on brain development and behaviour. Furthermore, the ability of BPA to bind to specific hormone receptors and regulate gene expression may contribute to stable and inheritable modifications, impacting growth, differentiation, and energy and nutrient metabolism.
While the U.S. Food and Drug Administration (FDA) has concluded that BPA levels typically found in food are safe, some watchdog groups and scientists argue for a more cautious approach. To minimise BPA exposure, it is recommended to avoid using plastic containers that are scratched or damaged, as they pose a higher risk of leaching chemicals into food. Switching to glass containers is advised, as they do not pose the same concerns regarding chemical leaching.

How to reduce exposure to BPA from plastics
Bisphenol-A (BPA) is an industrial chemical used in plastic manufacturing and added to many commercial products, including food containers, baby bottles, and plastic water bottles. It has been used since the 1960s to produce strong and resilient plastics. While the U.S. Food and Drug Administration (FDA) states that BPA is safe at the low levels sometimes found in foods, it can be harmful to pregnant people, unborn babies, infants, and children. Elevated exposure to BPA in children appears to trigger early puberty, heart conditions, obesity, weak immune system, and overall negative effects on health. In adults, it has been linked to diabetes, high blood pressure, and an increased risk of certain cancers.

Recognize Different Types of Plastics:
Understand the triangular plastic recycling codes embossed on plastic items. These codes, ranging from 1 to 7, indicate the type of plastic and its suitability for food contact. For example, Code 1 (PET or PETE) is considered safe for single use but may harbour bacteria or leach chemicals with repeated use or exposure to heat. Code 2 (HDPE) is known for its strength and safety in food contact.
Beware of BPA and Other Chemicals:
Bisphenol A (BPA) is a chemical commonly found in hard, clear, unbreakable polycarbonate plastics. It has potential health impacts, including effects on the brain and the prostate gland of fetuses, infants, and children, and possibly increasing blood pressure. While new plastics are often labelled "BPA-free," older containers may contain BPA. Look for recycling number 7, "unbreakable," or "microwave-safe" labels as indicators of potential BPA presence.
Choose Glass, Ceramic, or Stainless Steel Options:
Consider switching to glass, ceramic-coated glass, or stainless steel containers as safer alternatives. These materials are less likely to leach chemicals into your food. Look for brands like Pyrex, Caraway, and Klean Kanteen, which offer glass, ceramic, or stainless steel containers and lids that are safe, non-toxic, and environmentally friendly alternatives.
Practice Safe Usage:
Even if you choose plastic containers, you can minimize the risk of chemical leaching by avoiding high temperatures. Do not microwave or dishwash plastic containers, as heat can increase the leaching of chemicals. Instead, opt for gentle hand washing with warm, soapy water. Additionally, avoid storing hot foods or acidic foods like tomato sauce in plastic containers, as these can also increase the risk of chemical transfer.
Look for Alternative Storage Solutions:
Explore alternative storage options like silicone food storage bags, beeswax wraps, and cloth produce bags. These materials are free from harmful chemicals and provide safe and sustainable alternatives for storing and transporting food.
By following these guidelines, you can make informed choices about your food storage containers, reducing potential health risks for yourself and your family while also contributing to a more sustainable environment.
