Kitchen utensils and materials that generate concern and what safer alternatives to consider.

The kitchen is the heart of the home. There, the food that nourishes the family is prepared, moments are shared and memories are created. But behind that everyday space is a reality that many people don’t know: some of the objects we use every day can release substances that, over time, affect hormonal balance, inflammation in the body, and the risk of serious diseases.

Many of these items have been considered “safe” for years, but recent research shows that they can transfer invisible particles to food every time we cook, heat, or clean.

Below, you’ll learn about the eight most common hidden risks in the kitchen and what safe alternatives you can use.

8. Plastic Cutting Boards

Every time you cut on a plastic board, the knife gives off tiny particles that end up mixing with the food. Over time, these particles can accumulate in organs such as the liver, kidneys, and lungs.

In addition, when the surface is scratched, it becomes an ideal hiding place for bacteria.

Safe alternatives:
Natural wood boards (especially bamboo), tempered glass or marble.

7. Black plastic spatulas and utensils

Many black utensils are made from recycled plastic from electronics. That material may contain flame retardants and other toxic compounds that migrate into food when heated.

These substances disrupt the hormonal system, affect the thyroid, and have been linked to certain types of cancer.

Safe alternatives:
Utensils made of wood, stainless steel or certified food-grade silicone.

6. Scratched non-stick pans

When the nonstick coating is damaged, it releases stubborn chemicals that the body cannot easily eliminate. These can affect the immune system, liver, kidneys, and hormonal balance.

In addition, when overheated, these pans release toxic fumes.

Safe alternatives:
Cast iron, stainless steel or ceramic.

5. Plastic containers in the microwave

Heating food in plastic containers releases millions of microscopic particles, even those claiming to be “BPA-free.” Many of the substances that replace BPA also affect metabolism and hormones.

Safe alternatives:
Always use glass or ceramic containers to reheat food.

4. Low-quality silicone

Not all silicone is safe. Some inexpensive molds and spatulas contain plastics, heavy metals, and substances that are released by heat.

How to identify the safe:
It must be certified for food use. If it smells like a chemical or leaves color when rubbed, it is not suitable.

3. Contaminated spices

Some imported spices may contain lead, cadmium, or arsenic due to contamination of the soil where they are grown. These substances build up in the body over years.

What to do:
Buy spices from trusted brands, avoid products with no clear origin, and, if possible, grow herbs at home.

2. Chemical cleaners on food surfaces

Cleaning product residues can remain on countertops and boards and then pass into food.

Safe alternatives:
White vinegar, baking soda, or diluted solutions suitable for food contact surfaces.

1. Old kitchen sponges

Sponges are one of the most contaminated objects in the home. Billions of bacteria can live inside it, including those that cause intestinal and urinary tract infections.

The most dangerous thing is that cleaning or boiling a sponge does not make it safe: it often makes it even more dangerous.

What to do:
Change it every week or use antibacterial silicone brushes.

Tips and recommendations

• Change your utensils little by little, starting with the most harmful ones.
• Avoid heating food in plastic.
• Keep kitchen surfaces clean with safe products.
• Check the condition of your pans and cutting boards.
• Buy spices and utensils from trusted brands.

Your kitchen can be a place of health or an invisible source of risk. With small changes, you can reduce exposure to harmful substances and protect your family. Prevention isn’t exaggeration: it’s a smart way to take care of long-term well-being.
