The COVID-19 pandemic illuminated a vast landscape of misinformation about many topics, science and health chief among them.
Since then, information overload continues unabated, and many people are rightfully confused by an onslaught of conflicting health information. Even expert advice is often contradictory.
On top of that, people sometimes deliberately distort research findings to promote a certain agenda. For example, trisodium phosphate is a common food additive in cakes and cookies that is used to improve texture and prevent spoilage, but wellness influencers exploit the fact that a similarly named substance is used in paint and cleaning products to suggest it’s dangerous to your health.
Such claims can proliferate quickly, creating widespread misconceptions and undermining trust in legitimate scientific research and medical advice. Social media’s rise as a news and information source further fuels the spread of pseudoscientific views.
Misinformation is rampant in the realm of health and nutrition. Findings from nutrition research is rarely clear-cut because diet is just one of many behaviors and lifestyle factors affecting health, but the simplicity of using food and supplements as a cure-all is especially seductive.
I am an assistant professor specializing in medical education and science communication. I also train scientists and future health care professionals how to communicate their science to the general public.
In my view, countering the voices of social media influencers and health activists promoting pseudoscientific health claims requires leaning into the science of disease prevention. Extensive research has produced a body of evidence-based practices and public health measures that have consistently been shown to improve the health of millions of people around the world. Evaluating popular health claims against the yardstick of this work can help distinguish which ones are based on sound science.
Navigating the terrain of tangled information
Conflicting information can be found on just about everything we eat and drink.
That’s because a food or beverage is rarely just good or bad. Instead, its health effects can depend on everything from the quantity a person consumes to their genetic makeup. Hundreds of scientific studies describe coffee’s health benefits and, on the flip side, its health risks. A bird’s-eye view can point in one direction or another, but news articles and social media posts often make claims based on a single study.
Things can get even more confusing with dietary supplements because people who promote them often make big claims about their health benefits. Take apple cider vinegar, for example – or ACV, if you’re in the know.
Apple cider vinegar has been touted as an all-natural remedy for a variety of ailments, including digestive issues, urinary health and weight management. Indeed, some studies have shown that it might help lower cholesterol, in addition to having other health benefits, but overall those studies have small sample sizes and are inconclusive.
Advocates of this substance often claim that one particular component of it – the cloudy sediment at the bottom of the bottle termed “the mother” – is especially beneficial because of the bacteria and yeast it contains. But there is no research that backs the claim that it offers any health benefits.
One good rule of thumb is that health hacks that promise quick fixes are almost always too good to be true. And even when supplements do offer some health benefits under specific circumstances, it’s important to remember that they are largely exempt from Food and Drug Administration regulations. That means the ingredients on their labels might contain more or less of the ingredients promised or other ingredients not listed, which can potentially cause harms such as liver toxicity.
It’s also important to keep in mind that the global dietary supplements industry is worth more than US$150 billion per year, so companies – and wellness influencers – selling supplements have a financial stake in convincing the public of their value. https://www.youtube.com/embed/VM1zCZLCClM?wmode=transparent&start=0 Misinformation about nutrition is nothing new, but that doesn’t make it any less confusing.
How nutrition science gets twisted
There’s no doubt that good nutrition is fundamental for your health. Studies consistently show that a balanced diet containing a variety of essential nutrients can help prevent chronic diseases and promote overall well-being.
For instance, minerals such as calcium and iron support bone health and oxygen circulation in the blood, respectively. Proteins are essential for muscle repair and growth, and healthy fats, like those found in avocados and nuts, are vital for brain health.
However, pseudoscientific claims often twist such basic facts to promote the idea that specific diets or supplements can prevent or treat illness. For example, vitamin C is known to play a role in supporting the immune system and can help reduce the duration and severity of colds.
But despite assertions to the contrary, consuming large quantities of vitamin C does not prevent colds. In fact, the body needs only a certain amount of vitamin C to function properly, and any excess is simply excreted.
Companies sometimes claim their supplement is “scientifically proven” to cure illness or boost brain function, with no credible research to back it up.
Some companies overstate the benefits while underplaying the hazards.
For example, wellness influencers have promoted raw milk over pasteurized milk as a more natural and nutritious choice, but consuming it is risky. Unpasteurized milk can contain harmful bacteria that leads to gastrointestinal illness and, in some cases, much more serious and potentially life-threatening diseases such as avian influenza, or bird flu.
Such dietary myths aren’t harmless. Reliance on nutrition alone can lead to neglecting other critical aspects of health, such as regular medical checkups and lifesaving vaccinations.
The lure of dietary myths has led people with cancer to replace proven science-backed treatments, such as chemotherapy or radiation, with unproven and misleading nutrition programs.
How to spot less-than-solid science
Pseudoscience exploits your insecurities and emotions, taking advantage of your desire to live the healthiest life possible.
While the world around you may be uncertain and out of your control, you want to believe that at the very least, you have control over your own health. This is where the wellness industry steps in.
What makes pseudoscientific claims so confusing is that they use just enough scientific jargon to sound believable. Supplements or powders that claim to “boost immunity” often list ingredients such as adaptogens and superfoods. While these words sound real and convincing, they actually don’t mean anything in science. They are terms created by the wellness industry to sell products.
I’ve researched and written about reliable ways to distinguish science facts from false health claims. To stay alert and find credible information, I’d suggest you follow a few key steps.
First, check your emotions – strong emotional reactions, such as fear and anger, can be a red flag.
Next, check that the author has experience or expertise in the field of the topic. If they’re not an expert, they might not know what they are talking about. It’s always a good idea to make sure the source is reputable – ask yourself, would this source be trusted by scientists?
Finally, search for references that back up the information. If very little or nothing else exists in the science world to back up the claims, you may want to put your trust in a different source.
Following these steps will separate the facts from fake news and empower you to make evidence-based decisions.

Saving a Life This Summer: Ways to Step Up Safety Practices
Regardless of where you are, summer is a reminder that emergencies like cardiac arrest can happen anywhere. Take the safety of those around you into your own hands this summer with this checklist.
(Feature Impact) The busy summer season can take you almost anywhere – baseball fields, backyard cookouts, long workdays or road trips across the country. Regardless of where you are, summer is a reminder that emergencies like cardiac arrest can happen anywhere.
More than 350,000 out-of-hospital cardiac arrests occur in the United States each year, and 90% of people will not survive, according to the American Heart Association, a nonprofit organization devoted to changing the future for a world of healthier lives for all. Sudden cardiac arrest can happen anytime, anywhere. People often hesitate to step in. In fact, nearly 2 out of 3 adults believe CPR can only be performed by medical professionals. This mistaken belief can cost lives and contributes to the low survival rate.
Ordinary people have extraordinary power. You don’t need to wear scrubs or have a medical background to save a life – you just need the courage to act.
Take the safety of those around you into your own hands this summer with this checklist.
Plan Ahead
Summer is often a time for welcome disruptions, including vacations, camps, sports and parties. Before traveling or attending events, check if your destination has a cardiac emergency response plan, which establishes specific steps to reduce death from cardiac arrest in any setting, from schools and community organizations to workplaces and sports facilities.
Learn CPR
Cardiac arrest can happen anywhere: at home, at work, in schools, at a soccer game or on vacation. When it happens, the first chance for survival often rests with the people nearby.
Anyone can be the difference before professional help arrives. The power to save a life is in your hands. CPR is a human responsibility, not just a medical skill. When friends, family or even strangers step in during cardiac emergencies, survival rates can double or even triple.
Hands-Only CPR for adults consists of two easy steps:
- Call 9-1-1 or shout for someone else to call.
- Push hard and fast in the center of the chest to the beat of a familiar song that’s 100-120 beats per minute, such as “Stayin’ Alive” by the Bee Gees.
Share Resources with Your Family and Community
Once you’ve learned simple, two-step Hands-Only CPR, share resources with your community to help expand the American Heart Association’s Nation of Lifesavers. Raising awareness with family, neighbors and colleagues can help people feel confident in the face of an emergency.
Families can watch short instructional videos that demonstrate the life-saving steps for adults as well as techniques for infants and children.
Travelers can also get trained in about 5 minutes with a Hands-Only CPR Kiosk, located in many airports and public spaces across the country.

Summer Safety Tips
In addition to learning CPR and sharing valuable resources with your family and community, consider these ways to keep yourself and loved ones safe throughout the summer months.
- Stay Hydrated: High temperatures can quickly lead to dehydration and heat-related illness. Drink water regularly throughout the day, especially during outdoor activities, and pack extra water when away from home.
- Protect Your Skin: Hats, sunglasses and lightweight clothing can protect skin from sun exposure, but it’s important to use broad-spectrum sunscreen and reapply every 2 hours.
- Swim with a Buddy: Hopping in a pool, lake or ocean is a hallmark of summer but can be dangerous without precautions. Never swim alone and ensure children are always supervised by an adult near water.
- Identify the Locations of Safety Equipment: When attending camps, heading to a sporting event or enjoying the pool or beach, identify where lifeguards, AEDs and emergency exits are located. Knowing where to find help can save valuable time when every second counts.
- Practice Grill Safety: Some of your most memorable summer moments may happen during a backyard barbecue or cookout, and it’s important to keep those gatherings safe. Use grills away from homes, decks and dry grass. Never leave them unattended while cooking, and be sure kids and pets stay at a safe distance from hot surfaces.
Saving a Life Within 1 Year of Learning CPR
On a chilly Tuesday, dawn was breaking as Matthew Lynch reached his highway exit, but traffic was backed up at a particular intersection. He waited through three cycles before finally getting close enough to see the holdup: a stalled SUV.
While most cars buzzed by, Lynch moved slowly and peered into the vehicle. He saw people inside and parked his sedan, flipped on the hazard lights and ran to the stalled SUV. As he knocked on the driver’s window, there was no response. The doors were locked. Two people – a male driver and female passenger – were unresponsive.
Lynch ran back to his own car and called 9-1-1 before managing to open the driver’s side door. He discovered the driver was not breathing normally, signaling to Lynch he’d need to start CPR – which he’d learned 10 months earlier during a training session he’d helped organize for a work-sponsored men’s group.
Knowing he had to do something, Lynch started pushing hard and fast in the center of the man’s chest. Within a minute, the man gasped for breath.
Just as Lynch leaned over to see if he could help the female passenger, first responders arrived and Lynch backed away, knowing there was nothing more he could do.
“It was just a lot to take in,” said Lynch, a member of the American Heart Association’s 2026 Nation of Lifesavers Class, a small group of volunteers, dedicated to raising awareness of CPR by sharing their own personal stories of survival or rescue. “Mostly I felt an incredible sense of gratitude that I could help someone.”
A strong admirer of the Good Samaritan parable, Lynch is always on the lookout for the opportunity to help others. He learned a lot about himself in that moment and about the importance of learning CPR, along with the confidence that comes from knowing you could be a lifesaver.
“I quickly realized the certification was way less important than the actual CPR training,” he said. “Your ability to help in any capacity is better than doing nothing. If I hadn’t done that training, I probably would not have helped.”

How healthy is Sodastream?
The SodaStream Sparkling Water Maker is a device that forces carbon dioxide (CO2) gas (stored under pressure in a cylinder) into water, making it sparkling (fizzy)
Sodastream machines have been gaining popularity in recent years as an alternative to store-bought soft drinks. Not only are they more environmentally friendly, but they also offer several health benefits compared to traditional sodas.
Reduced Sugar Intake
One of the most significant health benefits of using a Sodastream machine is reducing sugar intake. Traditional sodas are loaded with sugar, and excessive sugar intake can lead to weight gain, obesity, and other health problems such as Type 2 diabetes. With a Sodastream machine, you can control the amount of sugar you add to your drink, allowing you to enjoy a refreshing beverage without the harmful effects of excessive sugar consumption.
No Artificial Sweeteners
Many store-bought soft drinks contain artificial sweeteners, which can have negative health effects such as headaches and digestive problems. Sodastream machines, on the other hand, allow you to use natural sweeteners such as fruit extracts, honey or agave nectar, giving you a healthier and more natural alternative.
No Preservatives
Another advantage of using a Sodastream machine is that you can avoid preservatives commonly found in store-bought soft drinks. Preservatives such as sodium benzoate and potassium sorbate have been linked to health problems such as cancer and allergies. By making your own drinks, you can avoid these harmful additives and enjoy a healthier, preservative-free beverage.
Eco-Friendly
In addition to the health benefits, using a Sodastream machine is also environmentally friendly. Traditional soft drinks are packaged in plastic bottles or cans, which contribute to environmental pollution. With a Sodastream machine, you can reuse the same bottle multiple times, reducing waste and helping to reduce your carbon footprint.
Variety
Finally, Sodastream machines offer a wide variety of flavors and options, allowing you to customize your drink to your liking. You can mix and match different flavors or create your own unique blends, giving you a healthier and more enjoyable alternative to traditional sodas.
In conclusion, Sodastream machines offer several health benefits compared to traditional store-bought soft drinks. By reducing sugar intake, avoiding artificial sweeteners and preservatives, and being eco-friendly, they offer a healthier and more sustainable alternative to traditional soft drinks. Moreover, with a wide variety of flavors and options, you can customize your drink to your liking, making it a fun and enjoyable way to stay healthy.

Harness Peanut Power for Improved Cognitive Health
A healthy brain goes beyond reading exercises and completing puzzles – it extends to the kitchen, too. Emerging nutritional science is clear that what people eat doesn’t just fuel the body; it shapes memory, mood and cognitive health.
(Feature Impact) A healthy brain goes beyond reading exercises and completing puzzles – it extends to the kitchen, too. Emerging nutritional science is clear that what people eat doesn’t just fuel the body; it shapes memory, mood and cognitive health.
Among the foods you can include in your diet to give your brain a boost are peanuts and peanut butter, staples valued not only for their convenience but also for their cognitive benefits. In fact, a study published in the “Journal of the Prevention of Alzheimer’s Disease” found adults 60-80 years old who did not eat peanuts and peanut butter regularly were 30-50% more likely to perform poorly on tests measuring learning, memory, language, processing motor speed and attentiveness compared to those who did consumer peanuts and peanut butter.
It’s not just the older generation that can benefit. According to research published in “Clinical Nutrition,” a study of college students ages 18-33 showed consumption of peanuts and peanut butter was associated with improved memory function and decreased anxiety, depression and stress.
Consider this key information from the Georgia Peanut Commission before your next meal planning session.
Nutrients that Give the Brain a Boost
Despite their small stature, peanuts pack a nutrition punch. Their unique blend of various vitamins, minerals and bioactive compounds includes:
- Niacin, which can slow cognitive decline and reduce the risk for Alzheimer’s disease, according to the “Journal of Neurology, Neurosurgery and Psychiatry”
- Vitamin E, found to promote healthy brain aging and delay cognitive decline
- Resveratrol, believed to be beneficial in fighting against Alzheimer’s disease and other nerve degenerating diseases, per the “Journal of Biological Chemistry”
- P-coumaric acid, an antioxidant that appears to target the neurotransmitters in the brain that regulate mood, stress and anxiety
Peace of MIND
Peanuts are included in the MIND diet, a combination of the Mediterranean and DASH diets, which specifically includes foods shown to benefit the brain.
Adding peanuts to your menu can be a breeze. Look no further than a powerful main course like Crunchy and Creamy Cold Green Pea and Peanut Salad, a perfect accompaniment at potlucks and cookouts as an easy side or light main course.
Brain Food for Thought
Supporting your brain starts with the right nutrition, and evidence makes clear peanuts and peanut butter should be top-of-mind as you head to the grocery store. For help getting started, find more recipes and nutritional information by visiting GAPeanuts.com.
