Chewing gum may seem harmless, or even like a jaw workout, but it can be harmful. Why? Because it is a hidden source for microplastics that you may be chewing with the gum. A new study presented at the American Chemical Society meeting in San Diego has found that a single piece of gum can release hundreds or even thousands of microplastics particles into saliva.

Microplastics are plastic fragments smaller than five millimeters. While most foods are contaminated with microplastics through packaging and processing, gum is unique, because its base contains synthetic polymers. These polymers are essentially plastics, and they are used to maintain the gum's texture and elasticity.

According to the study, both synthetic and natural gums release microplastics at similar rates. The primary types of plastic detected were polyolefins, polyterephthalates, polyacrylamides, and polystyrenes—materials commonly found in packaging and consumer goods. When gum is chewed, the friction breaks down the polymers, releasing these plastic particles directly into the mouth.

How Many Microplastics Are We Chewing With The Gum?

The researchers tested ten commercially available chewing gums and found that chewing just one gram of gum released an average of 100 microplastic particles. Some brands released as many as 637 particles per gram. Given that gum sticks often weigh more than a gram, the total exposure could be significantly higher.

Interestingly, most of the microplastics (94%) were released within the first eight minutes of chewing. This suggests that even short periods of gum chewing can contribute to microplastic exposure.

How Do Microplastics Affect The Human Body?

Microplastics can enter a human body through any medium, it could be food, water, or even air. Studies have detected these tiny particles in the lungs, liver, heart, intestines, brain, testicles, and even in placenta. One of the most alarming findings came from a researchers Dr Heather Leslie and her team in Netherlands. They were the first to detect microplastics in human blood.

Once these microplastics are inside the body, they can also cross biological barriers. For instance, some microplastics are small enough to enter bloodstream, where they become coated with fats and protein. It forms a 'corona' that then helps them evade the immune system. Microplastics have also been found in breast milk, semen, and it has raised concerns about their potential impact on the reproductive health.

Can the Body Get Rid of Microplastics?

Research suggests that most ingested microplastics exit the body through stool and urine. However, some particles are absorbed into the bloodstream and may accumulate over time in various organs. While the exact effects on human health remain uncertain, early studies have linked microplastic presence to inflammatory diseases, heart conditions, and reproductive health issues.

Are Microplastics Harmful to Humans?

The health risks of microplastic exposure are still under investigation. Some studies suggest potential links between microplastics and conditions such as heart disease, inflammatory bowel disease, and chronic sinusitis. For example, Italian researchers found that people with microplastics in arterial plaques were more likely to suffer heart attacks or strokes.

Though no direct causal link has been established, the growing body of research highlights the need for further studies. Scientists are particularly interested in how long-term exposure to microplastics might impact human health and whether certain types of microplastics pose greater risks than others.

What Can Be Done About Microplastics in Gum?

The National Confectioners Association, which represents gum manufacturers, maintains that chewing gum is safe. However, as awareness of microplastic contamination grows, consumers may start demanding gum made without synthetic polymers.

For those looking to reduce their exposure, switching to gum made entirely from natural ingredients—such as chicle, a plant-based alternative—could be a better option. Additionally, broader regulations and improved food safety standards could help minimize microplastic contamination in everyday products.

It started with a simple TikTok video, four large carrots shaved into ribbons, mixed with garlic, sesame oil, lime juice, coconut aminos, rice vinegar, and green onions. The resulting “crunchy and addictive” salad quickly racked up millions of views under the viral trend #EatYourRetinol. But is it just social media hype, or can what’s on your plate really show up on your face?

The trend encourages eating vitamin A-rich foods, like carrots, to support skin health from the inside out. “Skincare always starts within,” says Johanna Salazar, registered dietitian nutritionist and founder of Healing Nutrition, as noted by Martha Stewart. But experts urge a balanced view: while diet can support your skin, it’s not a magic replacement for topical care.

What’s in the Carrot Salad That’s Good for Your Skin?

The base of the salad, carrots, are packed with beta-carotene, a precursor to vitamin A, known for boosting skin cell turnover and promoting a radiant complexion. Pairing it with a fat, like sesame oil, helps your body absorb the fat-soluble vitamin. Lime juice adds vitamin C, key for collagen production, while garlic and green onion offer prebiotics that support gut health, which in turn impacts skin health.

Sesame seeds sprinkled on top bring in vitamin E and fiber, which contribute to skin hydration and a healthy glow.

“It’s a nice mix of ingredients that all play small but beneficial roles in skin support,” says Salazar.

Dermatologists Weigh In: Not a Cure-All

Lauren Kole, M.D., associate professor of dermatology at the University of Alabama at Birmingham, appreciates the effort to eat for skin health—but with a word of caution.

“Deficiencies in certain vitamins and minerals can negatively affect the hair, skin, and nails,” she says. “But eating an excess doesn’t necessarily make your skin better.”

Kole points out that while beta-carotene from carrots is helpful, it's not strong enough to replace prescription retinol or other topical treatments for conditions like acne or hyperpigmentation. “Diet is not a substitute for proper skin care,” she emphasizes.

Beyond Carrots: Other Skin-Loving Foods

Experts agree that eating for your skin isn’t just about one salad. A variety of fruits, vegetables, and healthy fats are essential. Salazar and Kole both recommend incorporating:

Dark-colored fruits like berries and red grapes, which are high in antioxidants that fight oxidative skin damage.

Leafy greens such as spinach, kale, and chard, which are rich in vitamin C and help with collagen production.

Vegetables like broccoli, mushrooms, and cauliflower, which support healthy pigmentation and skin repair.

Healthy fats including avocados, walnuts, flaxseeds, and omega-3-rich foods to reduce inflammation and maintain skin moisture.

According to Kole, diets like the Mediterranean diet—rich in plant-based foods and good fats, have shown potential skin benefits in clinical settings.

Don’t Ditch Your Skincare Just Yet

While the “Eat Your Retinol” movement has its heart in the right place, Salazar and Kole stress that no food trend should replace professional skincare or personalized advice.

Lizzy Davis, Ph.D., a dietitian and assistant professor at UAB, advises people to approach such trends with balance.

“Cooking carrots, for example, doesn’t reduce their skin-friendly fiber,” she notes. “It can actually make them easier to digest and still beneficial.”

Davis also warns against over-relying on TikTok or Instagram for skincare advice. “Talk to your doctor or a registered dietitian,” she says. “Social media is convenient, but it can’t give you a plan tailored to your needs.”

We already know that ultraprocessed foods are linked to obesity, heart disease, and diabetes. But now, a new study published in the medical journal Thorax suggests a concerning addition to that list, lung cancer.

According to researchers, people who consume the highest amounts of ultraprocessed foods may face a 41% higher risk of being diagnosed with lung cancer, compared to those who eat the least, even when accounting for smoking and other known risk factors.

What Are Ultraprocessed Foods?

Ultraprocessed foods are industrial formulations made largely or entirely from substances not typically used in home cooking.

According to the Food and Agriculture Organization of the United Nations, these include artificial colorings, preservatives, emulsifiers, and chemically altered fats, sugars, or salts.

Common examples? Think sodas, chips, packaged soups, processed meats like chicken nuggets and cold cuts, instant noodles, diet soft drinks, and even some ice creams.

These additives enhance taste, shelf-life, and appearance, but at what cost?

What Does The Study Reveal About Food Choices and Lung Cancer Risk

Researchers behind the Thorax study analyzed data from over 100,000 adults who participated in the U.S. National Health and Nutrition Examination Survey. Each person filled out a detailed dietary questionnaire, which researchers then compared with medical records to track lung cancer diagnoses over time.

On average, people reported eating nearly three servings of ultraprocessed food a day, most commonly lunch meats and soft drinks.

Despite adjusting for smoking habits, age, sex, and other lifestyle factors, the study found a clear association between higher ultraprocessed food intake and increased lung cancer risk, particularly among people who had never smoked.

“This strongly suggests that these foods may contribute to lung cancer risk in ways beyond just smoking,” said Dr. David Katz, a specialist in preventive and lifestyle medicine and founder of the nonprofit True Health Initiative, as reported by CNN. Though not involved in the study, Katz called the findings “concerning and credible.”

Why Would Food Be Linked to Lung Cancer?

Experts believe multiple mechanisms could be behind the link.

“Industrial processing alters the food matrix,” the study authors explained, “which affects how nutrients are absorbed and may produce harmful contaminants.”

One such contaminant is acrolein. It is a toxic compound found not only in cigarette smoke, but also produced when cooking oils or fats are heated to high temperatures.

The U.S. Centers for Disease Control and Prevention (CDC) lists acrolein as a substance that can inflame and damage lung tissue.

Packaging may also be a problem. Plastics and synthetic materials used in food storage can leach chemicals, some of which are known or suspected carcinogens.

Add to that the fact that ultraprocessed foods are often low in omega-3 fatty acids, said Dr. Tom Brenna, professor of nutrition and chemistry at the University of Texas at Austin, as reported by CNN.

“Omega-3s spoil easily, so manufacturers tend to remove them to increase shelf life,” he explained. That’s unfortunate, because omega-3s help reduce inflammation, a key process in cancer development.

Smoking Isn’t the Only Risk Factor

Lung cancer remains one of the most commonly diagnosed cancers globally, with 2.4 million new cases in 2022, according to the World Health Organization. While smoking remains the leading risk factor, experts now believe diet and environmental exposures also play a role.

Dr. Fang Fang Zhang, a professor at Tufts University’s Friedman School of Nutrition Science and Policy, as reported by CNN, noted that while the study adjusted for smoking, the adjustment may not have been thorough enough. “Smoking needs to be measured more precisely, by cigarettes per day or years of exposure,” she said. Still, she found the link stronger in non-smokers, which makes the data all the more compelling.

What You Can Do: Eat More Whole Foods

The takeaway? While more research is needed to understand the exact biological mechanisms at play, the connection between ultraprocessed foods and cancer risk can no longer be ignored.

According to Dr. Katz, the solution lies in going back to basics. “Health and diet quality improve when people eat mostly whole, unprocessed foods,” he said, including vegetables, fruits, beans, whole grains, nuts, seeds, and other plant-based ingredients.

Dr. Zhang agrees. “Avoid foods with long ingredient lists full of unfamiliar chemicals,” she advised. “Focus on meals made from whole or minimally processed ingredients whenever possible.”

Fish oil is a star supplement loaded with omega-3 fatty acids like EPA and DHA. It offers a spectrum of vital benefits for women’s health. These extend beyond general well-being to support heart, brain and joint function, especially in areas of concern specific to women.

Fish oil, rich in omega-3s, addresses unique needs across all stages of a woman’s life. From adolescence through motherhood to menopause, fish oil supports cardiovascular, hormonal, mental and reproductive health.

A Boost for the Heart

Fish oil plays a major role in promoting heart health. According to Dr Mohit Bhatia, it helps lower triglyceride levels, a risk factor for cardiovascular disease, and improves blood flow, making it essential for proper cardiovascular function. He adds that it also slows the progression of cardiovascular disease.

Karan Khurana, a health expert at WishNew Wellness, concurs, saying that omega-3s in fish oil reduce triglycerides, lower blood pressure, and decrease arterial inflammation. This is particularly vital for post-menopausal women, who face a greater risk of heart disease. Regular consumption of fish oil, he says, can even lower the risk of heart attacks and strokes.

Hormones, Menstrual Cycles and PMS

Women facing bloating, mood swings or cramps may find some relief with fish oil. Dr Bhatia says that some evidence-based research suggests fish oil can help alleviate PMS and menstrual pain, thanks to its anti-inflammatory properties.

Khurana elaborates that omega-3s may regulate menstrual cycles and reduce cramps by lowering prostaglandin levels, which contribute to pain and inflammation. He adds that fish oil can ease common PMS symptoms such as bloating and breast tenderness.

Pregnancy, Postpartum and a Baby’s Brain

The benefits of fish oil carry into pregnancy too. Dr Bhatia points out the importance of DHA during this stage, saying it is vital for healthy foetal brain and eye development. It may also reduce the risk of preterm birth and help alleviate postpartum depression.

Khurana backs this up, pointing out that fish oil supplementation not only supports cognitive function in babies but also helps mothers manage postpartum depression. It plays a role in maintaining the mother’s brain health during and after pregnancy.

Bones, Joints and the Menopause Years

Post-menopause, bone health becomes a serious concern for many women. Dr Bhatia says that the anti-inflammatory properties of fish oil can contribute to bone health, potentially reducing the risk of osteoporosis.

Khurana adds that omega-3s enhance calcium absorption and support bone density. Fish oil, he explains, helps reduce inflammation linked to joint pain, promoting stronger bones and better mobility for older women.

Better Moods and Sharper Minds

Women are more likely than men to experience anxiety and depression, and fish oil might just help. Dr Bhatia explains that these fatty acids play a role in elevating mood and supporting brain function, potentially mitigating cognitive decline.

Khurana agrees, saying omega-3s support cognitive health and reduce the risk of dementia later in life. Fish oil, he says, may alleviate symptoms of depression and anxiety, contributing to overall mental well-being.

Your Skin Will Thank You Too

Dr Bhatia does not touch on it, but Khurana dives into skin benefits. He says that fish oil improves hydration, reduces wrinkles, and protects against UV damage. Its anti-inflammatory effects can ease conditions like eczema, making skin look and feel healthier.

Final Thoughts Before You Pop That Capsule

Dr Bhatia emphasises that while fish oil is a powerful supplement, it should complement a balanced diet and healthy lifestyle. He strongly recommends consulting a healthcare professional before starting, especially for those on medication or with existing conditions.

Khurana suggests aiming for 250–500 mg of combined EPA and DHA daily, either through fatty fish like salmon or through supplements. Fish oil, he concludes, is a holistic powerhouse that can help women thrive at every stage of life.
