Stainless steel and cast-iron pans should be used over older nonstick cookware

When it's good for your food to stick in the pan

Non-stick cookware has wired us to think any sticking in the pan is bad. While that's true for cleaning purposes, some foods—like thin smash burgers or sauces—require that stickiness to achieve the right taste or shape.

BPA-free plastics often contain other harmful 'forever chemicals'

These molecules are widely used in single-use plastics, may leach into food, resist breakdown, and can build up in the human body. They have been linked to obesity, heart disease, and neurological issues, particularly when heated.

'Last Week Tonight' explores the risks of forever chemicals (warning: language)

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals used in a wide range of products due to their unique properties. However, because they can persist in the body and environment for thousands of years, they’ve earned the moniker “forever chemicals”—and have been linked with numerous health risks.

Why bacterial bioremediation may help counter the negative effects of past chemical solutions

Molecules such as DDT, a synthetic insecticide, and PFAS—"forever" chemicals used to make products resistant to heat, water, and grease—have historically been used across various industries but are now known to be harmful. Microbes that can convert some of these substances into nontoxic products, such as water and carbon dioxide, have already been identified, with ongoing research to find others.

Why it's so hard to end the use of toxic lead

Lead was one of the earliest metals mined on Earth, desired for its soft malleability and used in cosmetics, pipework, gasoline, and more. But even though researchers demonstrated its toxicity in the 20th century, much of the world still uses it.

The challenges of trying to study microplastics in microplastic-abundant labs

The presence of microplastics in instruments, surfaces, and air has made accurate measurement of their levels in lab samples difficult, given the high likelihood of contamination. While the use of stainless steel tools in a sealed, clean lab may reduce accidental exposure, existing methods can misidentify biological substances, such as fat, as plastics, further complicating research.

The five most common chemicals found in modern food

Most modern processed foods rely on a number of preservatives to stay fresh from production to our plates. The most common include citric acid (preservative and flavor), sodium benzoate (preservative), xanthan gum (thickening and stabilizing), carrageenan (thickening), and red dyes 3 and 4 (for color).

Le Crueset's France factory makes 10,000 of its $400 cast-iron pots each day

After nearly going bankrupt in the 1980s, the company expanded its color options and product line to boost sales—something that's also fueled the brand's fanaticism. The Le Crueset Dutch oven was among Julia Child's kitchen staples, and the 2009 hit "Julie & Julia" reintroduced Child's famous Dutch oven to a new generation, resulting in a sales boom.

Food poisoning can sometimes cause serious long-term health issues

Although foodborne illness can be relatively mild and cause short-term discomfort, more rarely it can also cause long-term severe health consequences, depending on your individual risk factors, the severity of your sickness, and the care you receive. Kidney failure is one serious complication associated with certain types of food poisoning. Meningitis, hepatitis, arthritis, and pancreatitis are also rare and serious foodborne illness complications. If a pregnant person gets food poisoning, it can cause health issues for the fetus.

At the beginning of the 20th century, a group of young men ate standard American food—replete with food additives like borax and formaldehyde—as part of government research to better understand food safety.

Acrylamide forms naturally during high-heat cooking through the Maillard reaction

While studies have shown it can damage DNA and potentially cause cancer in mice, humans absorb and metabolize acrylamide at different rates, introducing uncertainty in the research's applicability to humans. Some international health agencies have nonetheless recommended avoiding darker roasts when cooking starchy foods.

An investigation suggests a Scottish island became awash in forever chemicals via seafoam and seaspray—raising questions about what that means for the safety of other coastal areas.

Tattoo inks are largely unregulated by the FDA

With hundreds of ink manufacturers, all unregulated by the FDA, it’s hard to determine the exact ingredients in tattoo inks. Some pigments may contain carcinogenic chemicals, such as heavy metals and aromatic hydrocarbons, or even bacterial contaminants. Red ink often causes allergic reactions and may even contain lead or mercury.

Volatile chemical contamination can last in burn areas long after urban wildfires

Lead, arsenic, asbestos, and other chemicals have been found trapped in smoke-exposed rugs, couches, pillows, and other furniture that appeared otherwise undamaged from the 2025 LA wildfires. The gradual release of these substances has produced dangerous indoor air concentrations and contributed to increased emergency room visits and abnormal blood tests.

Items in the Curie Museum do not produce significant radioactivity today

Ionizing radiation produced by elements such as uranium, polonium, and radium can damage living things, but the trace amounts found in the museum objects that Marie Curie once touched have been largely decontaminated, with more dangerous items stored in protective, lead-lined containers.

Just because leftovers look and smell okay doesn’t mean they’re safe to eat

Despite what the sniff test is telling you, older leftovers should probably be trashed. Pathogens that cause illness don’t usually affect the taste, smell, or appearance of food (though if they look bad, you should chuck them as well). Scientists recommend tossing leftovers within a few days even if they appear to be fine.

Rachel Carson didn't argue for wholly organic farming

Her 1962 book, “Silent Spring,” inspired many people to consider the chemicals used to grow their food, but Carson didn’t think that manufactured fertilizers needed to be banned from farming, writing that “The ultimate answer is to use less toxic chemicals so that the public hazard from their misuse is greatly reduced.” When she testified to Congress in 1963, she said, “I think chemicals do have a place.”

Food allergies were first documented more than 4,000 years ago

Although food allergies are on the rise in modern times, they have been documented in written records for thousands of years. More than 3,000 years ago, Chinese emperors advised patients to avoid certain foods, and Hippocrates noted in his work that food could cause serious harm to certain individuals, and even lead to death.

FDA has removed black box warnings from HRT for menopause

The agency removed the label in 2025, reversing its 2003 decision to warn women about HRT's links to stroke risk, developing cancer, and heart disease. Years of accumulating research have found that the risks had been overstated and unnecessarily deterred hormone therapy use. The agency still warns against using certain estrogen-alone products, however, due to elevated endometrial cancer risk.

Cancer rates are on the rise among GenXers and Millennials

Cancer rates are rising among Gen X and Millennials, with more cancer diagnoses being made in their 30s and 40s than previous generations. Factors such as prenatal exposures, environmental toxins, and lifestyle choices may contribute to this trend. Memorial Sloan Kettering Cancer Center's experts discuss these issues, exploring how these insights could reshape cancer risk understanding.

Roman concrete lasts longer than modern recipes—and even gets stronger

Today's concrete is made by binding ingredients, including chalk and silica sand, at high temperatures. Unfortunately, it weakens when exposed to salt water. This article explores how and why scientists are studying ancient Roman concrete, which grows stronger when exposed to salt water.

How the methods of catching fish for food affects their taste

Commercially caught fish are often killed through suffocation, allowing the causing the fish extreme stress and flooding their bodies with stress hormones and lactic acid. These chemicals cause the fish's flesh to become bitter where it was once rich and quickens the rotting process.

Improved 19th-century sanitation meant kids encountered polio later, with worse results

Almost all children likely used to contract poliovirus, but scientists suggest that when infants encountered it very early in life—due to poorer conditions and hygiene—they still had some maternal protection from pregnancy or through breastmilk, so the symptoms were more flu-like.

Listen to an in-depth conversation on the links between Parkinson's disease and herbicide exposure and the challenging pace of scientific investigation.

Are seed oils as bad as rumors say?

Some claim seed oils—oils extracted from seeds, such as sunflower or canola—increase inflammation and disease risk, advising consumers reach for saturated fats instead. Saturated fats, typically solid at room temperature, are found in animal products and some vegetable oils, including coconut. When adjusting for lifestyle risk factors, research shows seed oils are, on average, good for one's heart and considered healthy alternatives to saturated fat.
