Hormones and your kitchen: how daily exposure affects your hormonal balance

This isn’t a scare story. It’s simply information most people don’t have — and it can be really useful. Because your hormone balance is influenced by small, everyday choices. And a big part of those choices happens in the kitchen.

What are hormone-disrupting substances?

Hormone-disrupting substances (endocrine disruptors) are chemicals that mimic, block, or interfere with the way hormones work in the body. They bind to hormone receptors and send out false signals.

The body trusts those signals — and responds to them. That can lead to:

• Disruptions to thyroid function
• Changes in fertility (in both men and women)
• Early puberty in children
• Increased risk of hormone-dependent cancers (breast, prostate)
• Insulin resistance and weight gain

The most common sources in the kitchen

PFAS — found in non-stick pans, some food packaging, and water-repellent materials. PFAS disrupt the thyroid, the immune system, and reproduction.

BPA and BPS — in certain plastics, cans, and thermal paper (receipts). BPA mimics estrogen.

Phthalates — in soft plastics and some food wraps. Disrupt testosterone and estrogen.

Parabens — in cosmetics, but also in some plastic packaging as a preservative.

How big is the risk?

Honest answer: it depends on the amount and duration of exposure. One pizza from a box with a PFAS coating won’t harm you. But daily exposure through multiple sources — your pan, your plastic containers, your packaging, your water bottle — adds up.

The RIVM concluded that people in the Netherlands already take in more PFAS than is healthy, especially women of childbearing age and children.

What can you do?

The most impactful changes, in order of effect:

1. Replace damaged non-stick pans — this is where the biggest exposure is
2. Use glass containers for reheating — never put plastic in the microwave
3. Drink from glass or stainless steel — no plastic bottles, not even BPA-free
4. Choose wooden or silicone kitchen utensils — no plastic spatulas
5. Use glass food storage — especially for fatty foods and acidic products

You can’t change everything at once, and you don’t have to. But every step counts. The kitchen is one of the few places where you have direct control over what ends up in your body.
