Choosing healthy ingredients is important, but have you ever considered whether the utensils you cook and eat in could also affect your health? From stainless steel pans to plastic food containers, the material of your kitchenware can influence food safety, especially when utensils are exposed to high temperatures or used with acidic ingredients.

Dr. Shubham Vatsya, a gastroenterologist and hepatologist based in New Delhi, has discussed the safety of different utensil materials and highlighted the factors people should consider when choosing cookware for everyday use.

Here is a closer look at six commonly used materials and their potential health implications.

1. Plastic Containers: Use With Caution

Plastic containers are popular for storing leftovers, carrying lunch and keeping food organised. However, not every plastic container is designed to withstand high temperatures.

Heating food in unsuitable plastic containers can increase the migration of certain chemicals into food. Plastic can also degrade with repeated use, scratches and exposure to heat.

For safer use, choose containers specifically labelled as microwave-safe when reheating food. Avoid heating food in single-use packaging unless it is designed for that purpose, and consider glass or stainless steel alternatives for everyday storage.

2. Stainless Steel: A Reliable Everyday Choice

Stainless steel is widely used in Indian kitchens because it is durable, easy to clean and suitable for preparing a wide variety of dishes.

High-quality stainless steel cookware is generally considered safe for everyday cooking. It can release small amounts of metals such as nickel and chromium under certain conditions, particularly when new cookware is used to cook acidic foods for prolonged periods. For most people, this is not a significant concern, although individuals with relevant metal sensitivities may need additional caution.

With proper care, stainless steel remains one of the most practical choices for cooking, serving and storing food.

3. Glass Cookware: A Good Option for Food Storage

Glass containers are a popular alternative to plastic because ordinary food-grade glass is generally non-reactive and does not readily transfer chemicals into food.

Borosilicate glass is particularly useful for cookware and food storage when the product is specifically designed for the intended temperature and cooking method.

However, not all glass products are suitable for direct heating. Avoid exposing ordinary glass to sudden temperature changes, and always follow the manufacturer's instructions to reduce the risk of breakage.

4. Cast Iron: Durable Cookware That Can Add Iron

Cast iron cookware is valued for its excellent heat retention and ability to develop a naturally seasoned cooking surface. It is commonly used to prepare dosas, rotis, omelettes and other dishes.

One potential advantage is that cooking in cast iron can increase the iron content of food. The amount transferred depends on factors such as cooking duration, food acidity and the condition of the cookware.

However, prolonged cooking of acidic dishes, such as tomato-based gravies, can increase iron transfer and may affect the taste of the food. People with conditions that cause excessive iron accumulation should consult their healthcare professional before regularly using cast iron as an iron source.

5. Ceramic Utensils: Check the Quality of the Glaze

Ceramic plates, cups, bowls and cookware are common in households because of their appearance and versatility. Food-grade ceramic products with properly manufactured glazes are generally safe for everyday use.

The main concern is poorly manufactured, damaged or improperly glazed ceramic ware, which may release lead or cadmium into food. These metals can pose serious health risks when exposure occurs over time.

Choose products from reputable manufacturers and avoid using chipped, cracked or questionable decorative pottery for serving or storing food, particularly acidic dishes.

6. Aluminium Cookware: Choose the Right Type

Aluminium cookware is lightweight, conducts heat efficiently and is often more affordable than other alternatives.

However, aluminium can migrate into food, especially when cooking acidic or salty dishes for extended periods. Anodised aluminium has a protective surface that generally reduces this transfer when the coating remains intact.

If you use aluminium cookware, avoid storing highly acidic foods in it for long periods and replace cookware that is badly worn or damaged. For everyday cooking, stainless steel and suitable glass cookware are useful alternatives.

Which Kitchen Utensils Should You Choose?

Your choice should depend on how you intend to use the utensil, its quality and the condition of its surface.

• For everyday cooking: High-quality stainless steel is a practical option.

• For food storage: Food-grade glass is a good choice, especially for leftovers.

• For traditional cooking: Well-maintained cast iron can be useful.

• For plates and cups: Choose food-safe ceramic products from reliable manufacturers.

• For lightweight cookware: Properly maintained anodised aluminium is worth considering.

• For reheating food: Use microwave-safe glass or containers specifically designed for microwave use.

Final Takeaway

Kitchen safety involves more than choosing fresh vegetables, quality oils and nutritious ingredients. The utensils you use, the way you heat food and the condition of your cookware also matter.

Stainless steel and food-grade glass are generally dependable options for everyday use, while cast iron, ceramic and aluminium can also be suitable when used correctly. Plastic containers should be chosen according to their intended use, especially when heating food.

Rather than relying only on material ratings, focus on product quality, safe cooking practices and proper maintenance. Small choices in the kitchen can help make everyday meals safer for the entire family.
