What Chemicals Should I Avoid in Food Containers?

Stiff plastic containers are usually made with chemicals like BPA and BPS, while softer plastic items like Ziploc bags often contain phthalates.

These hazardous compounds can seep into the stored food and then into our bodies, posing a risk of various health complications.

Here’s a little more about each toxic chemical:

❌ Bisphenol A (BPA): Often used in producing plastics and epoxy resins, BPA can be found in various everyday items such as food containers, water bottles, and even the lining of canned goods. It’s a known endocrine disruptor and has been associated with hormone-related issues, potentially impacting fertility and increasing health risks.3

❌ Bisphenol S (BPS): Increasingly used as a BPA substitute in various products, BPS is also found in items like thermal paper receipts and some plastics. While it’s marketed as a safer alternative, emerging research suggests that BPS shares many of the harmful effects of BPA, including endocrine disruption and potential impacts on fetal development.4

❌ Phthalates: Often hidden under “fragrance” in cosmetics, personal care products, and plastic items. Phthalates can cause skin irritation and increase the risk of asthma and allergies. They are also endocrine disruptors, potentially affecting hormones and fertility.5

Taking Action

Now that you’re armed with knowledge about non-toxic storage containers, here’s how you can take action:

  1. Assess your current food storage containers and replace any that may be toxic.
  2. Invest in high-quality, non-toxic storage containers for your pantry and fridge that suit your needs.
  3. Educate friends and family about the importance of non-toxic food storage.

Remember, making informed choices about the containers you use for food prep can contribute to your overall well-being and help reduce your environmental footprint.
