What is The Truth About BPA In Cans and How Does It Affect You?

BPA, or Bisphenol A, is an industrial chemical used in the production of certain plastics and resins. For decades, it’s been a go-to material for lining cans and tins, thanks to its ability to prevent corrosion and preserve food. The inner lining ensures your baked beans or soup stay fresh and safe from metallic contamination. But despite these benefits, BPA has raised health concerns that have sparked debates among scientists and consumers alike.

Is BPA Harmful to Your Health?

The concern over BPA stems from its ability to mimic oestrogen, a hormone in the human body. This property categorizes BPA as an endocrine disruptor, which can potentially interfere with hormonal balance. While studies on BPA exposure continue, potential health risks include:

• Hormonal changes: Prolonged exposure could impact reproductive health.
• Increased risk of certain illnesses: Some studies suggest links between BPA and conditions such as heart disease and diabetes.
• Effects on children: Developing bodies are particularly vulnerable to endocrine disruptors, raising concerns about BPA in baby food containers and tins.

That said, many food safety authorities, including the European Food Safety Authority (EFSA), maintain that BPA exposure through cans is within safe limits for most people. However, the debate continues as new research emerges.

How Can You Limit BPA Exposure From Cans?

If you’re looking to reduce your BPA exposure, you’re not alone. Here are some practical tips:

• Choose BPA-free products: Many brands now label their cans as BPA-free. Keep an eye out for these alternatives on your next shop.
• Switch to glass or carton packaging: Glass jars and Tetra Paks are safer choices as they don’t require BPA-lined coatings.
• Avoid heating canned foods in their packaging: Heat can cause BPA to leach into food. Transfer your food to a non-plastic, microwave-safe dish before heating.
• Eat fresh or frozen foods: These are free from BPA concerns and offer additional health benefits.

Are All Cans BPA-free Now?

Not all cans are BPA-free, but the good news is that many manufacturers are taking steps to phase out its use. In various countries, several brands and supermarket chains now offer BPA-free alternatives. Still, it’s worth checking labels or contacting manufacturers directly if you’re unsure.

While the use of BPA in cans has its benefits, the potential health risks are worth considering. Being mindful of the types of packaging you choose and seeking out safer alternatives can go a long way in protecting your health. Next time you’re restocking your pantry, take a moment to think about what’s in — and around — your food.
