Many of us store leftovers, meal prep, or even heat food in plastic containers without a second thought. While plastic may seem convenient, research shows it can have hidden costs to our health—particularly when it comes to hormones and fertility.
Plastic and Hormone Disruption
Plastics often contain chemicals such as BPA (bisphenol A) and phthalates, which can leach into food and drinks, especially when containers are heated or scratched (think chopping boards). These chemicals are known as endocrine disruptors—they interfere with the body’s hormone system. Hormones control vital processes including reproduction, metabolism, and growth. Disrupting them can have wide-reaching effects.
For fertility, exposure to these chemicals has been linked to reduced sperm quality, altered hormone levels, and challenges with egg quality and ovulation. Even low-level, ongoing exposure matters, since these substances can build up in the body over time – recent research has found them in our brain!
Why Glass is a Better Choice
Switching to glass in the kitchen is a simple yet powerful step for protecting hormone health:
Chemical-free: Glass does not contain BPA, phthalates, or other hormone-disrupting chemicals.
Safe with heat: Unlike plastic, glass won’t leach chemicals when microwaved, dishwashed or used with hot foods.
Durable & sustainable: Glass lasts longer, resists scratches, and can be recycled endlessly, reducing waste.
Better for taste & freshness: Glass doesn’t absorb food smells or stains, keeping meals fresher.
Practical Tips for Making the Switch
Start small by replacing the containers you use most often, like lunch boxes or leftover storage.
Invest in glass jars for pantry staples—great for both storage and reducing packaging waste.
Replace any plastic chopping boards with stainless steel alternatives.
Use glass water bottles or stainless-steel alternatives to cut down daily exposure.
Final Thoughts
While plastic may be everywhere, we do have choices in our kitchens. By swapping plastic for glass, you not only reduce your exposure to hormone-disrupting chemicals but also take a proactive step to support fertility, hormone balance, and long-term health. Small, mindful changes like this can make a big difference over time.
