Three Kitchen Items You Should Replace More Often

There are many things in the kitchen that we use daily without much thought, but their physical condition and the material they are made of can indicate the need for replacement over time. According to experts speaking to Tportal, three items deserve special attention: plastic cutting boards, pans with damaged nonstick coatings, and scented candles.

Their warnings do not imply that occasional use of these items will certainly cause health problems. However, some issues they raise, from microplastics to PFAS and indoor air pollution, have long been the subject of scientific studies.

Plastic Cutting Boards

First on the list are plastic cutting boards. The problem arises from something we all notice after prolonged use: the surface becomes covered with scratches and knife marks over time. During cutting, very small plastic particles can be released, and research has shown that plastic boards can be a source of microplastics in food.

It is not yet entirely clear what health risk the amount of microplastics we are exposed to in this way poses, so there is no need to panic. However, if the board is already deeply scratched and worn, there is a valid reason to replace it. Experts recommend wooden or bamboo boards as an alternative. Wood is very gentle on knives, but like any board, it needs proper washing, thorough drying, and replacement when it becomes difficult to maintain. Glass boards are easy to clean but have another drawback: they dull knives very quickly.

Scratched Nonstick Pans

The second category deserves a bit more nuance. It is not necessary to discard every pan with a nonstick coating just because of that characteristic, but if the coating is significantly damaged and worn, that is a valid reason to buy new cookware. For years, chemicals known as PFAS, which have been used in various industrial and consumer products for their resistance to water, grease, and high temperatures, have been a particular concern.

One of these chemicals is PFOA, which was previously used in the production of some nonstick coatings but has been phased out of such manufacturing in many markets over time. Therefore, an old pan and a new nonstick pan are not necessarily the same thing.

With modern cookware, it is important to follow the manufacturer's instructions: do not heat an empty pan, use utensils that will not damage the surface, and replace it when the coating is heavily scratched, peeling, or no longer works properly. If you want to avoid nonstick coatings altogether, durable alternatives are stainless steel and cast iron, although they require a different cooking technique.

Scented Candles

In third place are scented candles. When these candles are burned, small particles and volatile organic compounds can be released into the air, and the composition of these emissions depends on the wax, fragrance, wick, burning method, and other factors. This does not mean that a single candle occasionally lit during dinner will pose a serious health risk. However, if you use them frequently, especially in a small, poorly ventilated space, it is wise to pay attention to ventilation and product quality.

As an alternative, experts recommend candles without added fragrances, including those made from beeswax, soy wax, or coconut wax.

What Is the Real Message?

The most important message of these warnings is not that you should immediately empty your kitchen cabinets. It is much more useful to periodically inspect the items we use daily. A deeply scratched plastic board, a pan with a damaged coating, or daily burning of intensely scented candles in a closed room are good reasons to consider whether there is a better alternative.

When it comes to health, replacing one board or pan will not magically solve all problems. But reducing unnecessary exposure to substances we are still learning about can be a simple and reasonable step, especially when affordable alternatives exist.
