What Is It and Why Is It Concerning?

A Critical Discussion of BPA in Canned Foods – BPA, or Bisphenol A, is a chemical commonly found in the coatings of canned food products. It has become a topic of concern because of its potential health risks. In this article, we will explore what BPA means in canned food and why it has received such attention. We will also discuss the potential effects of BPA on our health and how to minimize exposure.

BPA is used in the production of polycarbonate plastics and epoxy resins. In the case of canned food, BPA is used in the lining of the can to prevent corrosion and extend the shelf life of the food. A thin layer of BPA-based epoxy resin acts as a barrier between the metal can and the food, protecting the can and preserving the quality of the food.

However, there are concerns about the potential health risks associated with BPA exposure. Research shows that BPA can mimic the effects of estrogen, a hormone that plays an important role in various physiological processes. This has raised concerns about the potential for hormonal disruption caused by BPA. Studies have linked BPA exposure to reproductive disorders, developmental abnormalities, and potential effects on the brain and behavior.

Health Problems Associated with BPA

Potential Hormone Disturbances

Research shows that BPA has the potential to interfere with the endocrine system, which is responsible for regulating the production and function of hormones in the body. BPA can mimic the effects of estrogen, a hormone that plays an important role in various physiological processes. BPA exposure has been linked to reproductive disorders, developmental abnormalities, and potential effects on the brain and behavior.

Increased Risk of Chronic Disease

Several studies have also linked BPA exposure to an increased risk of chronic diseases such as obesity, diabetes, cardiovascular disease, and certain types of cancer. While the exact mechanism is still being studied, it is believed that the disruptive effects of BPA on hormone balance and metabolic processes may contribute to this health problem.

BPA and Children: Are They at Greater Risk?

Children are considered to be more vulnerable to potential risks of BPA exposure due to several factors. First, their bodies are still developing, and their systems may be more sensitive to outside influences. Second, children tend to have a higher food intake relative to their body weight than adults, meaning they may ingest more BPA per kilogram of body weight.

Research has shown that exposure to BPA in early life may have more pronounced effects in children than in adults. Animal studies show that BPA can influence brain development, behavior and hormone regulation. While direct causality in humans is difficult to establish, several studies have shown a link between BPA exposure and behavioral problems, neurodevelopmental disorders, and hormonal disturbances in children.

One area of ​​concern is BPA’s potential impact on the endocrine system, which plays an important role in regulating hormone production and function. BPA can mimic the effects of estrogen, a hormone involved in various developmental processes. Excessive estrogenic activity from BPA exposure can interfere with normal hormone signaling in children, potentially causing long-term health effects.

In addition, exposure to BPA during critical developmental periods, such as the prenatal and early childhood stages, may have long-term effects on a child’s health. These effects can include altered reproductive development, increased susceptibility to chronic disease, and potential impairments in cognitive and behavioral functioning.

Regulations and Guidelines

In response to the growing concern around BPA, authorities in several countries have taken steps to limit its use. Many countries, including the United States and the European Union, have banned the use of BPA in baby bottles and formula packaging. However, regulations regarding BPA in canned foods vary by region. It is very important to stay informed about the guidelines and regulations in your particular country or region.

How to Minimize BPA Exposure

To reduce BPA exposure from canned food, here are some practical tips:

  1. Choose Fresh Foods: Choose fresh fruits, vegetables and meat whenever possible. Fresh food is not packaged in cans eliminating the risk of BPA exposure.
  2. Choose BPA-Free Canned Foods: Look for canned food products that are labeled BPA-free. Several manufacturers have started producing BPA-free cans or alternative packaging materials.
  3. Transferring Canned Food to Glass or Ceramic Containers: If you must use canned food, consider transferring it to glass or ceramic containers for storage. This reduces contact between the food and the can lining, minimizing BPA migration.
  4. Avoid Microwaving Canned Foods: Heat can increase the migration of BPA from the lining of the can to the food. If possible, transfer the contents of canned food to a microwave-safe container before reheating.
  5. Check Recycling Codes: The multiple recycling codes on the bottom of a plastic container indicate whether the container contains BPA. Look for recycling codes 3 or 7, as they may indicate the presence of BPA.


While canned food provides convenience and a long shelf life, it’s important to be aware of the potential risks associated with BPA exposure. Research shows that BPA can have hormonal disruptive effects and may increase the risk of chronic disease. By following guidelines, such as choosing fresh foods, choosing BPA-free cans, and minimizing your use of canned foods where possible, you can reduce your BPA exposure and promote a healthier lifestyle.

FAQ (Frequently Asked Questions)

  1. Is BPA only found in canned food? No, BPA can also be found in a variety of other consumer products, including plastic bottles, food containers and thermal paper receipts.
  2. Are all canned foods high in BPA? BPA levels in canned foods can vary depending on the specific product and the manufacturer. Opting for BPA-free cans or fresh alternatives is a good way to reduce exposure.
  3. Can BPA migrate to food stored in glass jars? The migration of BPA is primarily associated with the use of cans lined with BPA-based epoxy resins. Glass jars do not have this coating, reducing the risk of BPA migration.
  4. How can I identify BPA-free canned food? Look for a label or certification that says the can is BPA-free. Manufacturers often highlight this information on the packaging.
  5. Is BPA also harmful to adults, or is it primarily a concern for children? While the potential health risks associated with BPA are of concern to all age groups, infants and children may be more vulnerable due to their developing systems. However, minimizing exposure benefits everyone.
