From the unexpected health risks lurking in everyday items to new insights about nutrition, 2024 brought a wealth of fascinating information. We delved into the world of vegetables, discovering that watercress is the most nutrient-dense, while also learning about the "Dirty Dozen" produce most likely to contain pesticides. Excessive consumption of fruit juice and fizzy drinks was shown to increase the likelihood of stroke, and a study even suggested that eating like salmon is better than eating actual salmon. Additionally, we uncovered the truth about PFAS in sparkling water, the risks of not washing lettuce, and the potential safety concerns of decaf coffee. These are just some of the highlights from this year's most-read science- and health-related stories.

Uncover the Surprising Science and Health Stories of 2024

Watercress Is the Most Nutrient-Dense Vegetable

According to the Centers for Disease Control and Prevention (CDC), watercress takes the lead as the most nutrient-dense vegetable. It offers an unbeatable combination of vitamins, minerals, and antioxidants. Vitamin K, in particular, is known to support bone health, improve digestion, and combat oxidative stress. This makes watercress a true powerhouse in our diets.Moreover, watercress's nutritional profile sets it apart from other common produce. Its unique blend of nutrients makes it a valuable addition to any meal, providing us with the essential elements our bodies need.

'Dirty Dozen' Produce: The 12 Most Contaminated Fruits and Vegetables

The annual "Dirty Dozen" list never fails to capture people's attention, and 2024 was no exception. The Environmental Working Group (EWG) ranked strawberries, spinach, and kale as the most likely to contain pesticide residues. While these are nutrient-rich foods, it's crucial to wash them thoroughly and, when possible, choose organic options.This highlights the importance of being aware of the potential contaminants in our produce. By taking these precautions, we can minimize our exposure to harmful pesticides and ensure the safety of the food we eat.

Consuming Too Much Fruit Juice and Fizzy Drinks Increases Your Likelihood of Stroke

Sorry, soda lovers, but studies have shown that excessive consumption of sugary beverages like fruit juice and soda can significantly increase the risk of stroke. The team couldn't pinpoint the exact link, but they explained that it likely stems from the high sugar levels in these drinks and their impact on blood pressure, inflammation, and vascular health.This serves as a reminder to be mindful of our beverage choices. Opting for healthier alternatives such as water or unsweetened tea can help reduce our risk of stroke and improve our overall health.

Eating Like Salmon Is Better Than Eating Actual Salmon

A 2024 study published in the Nature Food journal turned the traditional advice on its head. Instead of focusing on eating salmon directly, researchers emphasized the benefits of adopting the diet of wild salmon. Wild salmon is rich in omega-3s, algae, and nutrient-dense marine organisms, which it consumes through its diet of smaller fish like mackerel, anchovies, and herring.This approach offers a more sustainable way to support our health without overfishing the world's oceans. By incorporating these elements into our diets, we can reap the benefits of a healthy and balanced diet.

The Truth About PFAS in Your Sparkling Water

Once again, fizzy drink fans have some bad news. A 2024 study revealed that sparkling water often contains dangerous PFAS (per- and polyfluoroalkyl substances) chemicals. These "forever chemicals" have been linked to various health issues, including cancer and hormonal disruptions.In the study, several popular sparkling water brands were found to have PFAS levels higher than 1 part per trillion. The Environmental Working Group recommends drinking water with less than 1 ppt of PFAS, so it may be time to reach for some still water instead.

These Are the Risks of Not Washing Your Lettuce

It's always a good idea to wash our produce, and this year we were reminded that not doing so can lead to dangerous consequences. Not washing lettuce can increase the risk of contracting E. coli and Salmonella.Washing helps remove dirt and pesticide residues, providing an extra layer of protection. And while "pre-washed" lettuce claims may seem convenient, experts recommend washing it again at home for added safety.

Decaf Coffee Could Potentially Be Unsafe for Human Consumption

We hate to be the bearer of bad news, but in 2024, scientists published new findings about decaf coffee. It was noted that decaf coffee can often contain chemical solvents that may pose health risks to humans.However, not all decaf brands use the methods mentioned by the researchers. If you enjoy decaf coffee, it's worth taking the time to research the best options, such as water-processed decaf, to minimize potential risks.

These Are 4 of the Healthiest Vegetables You Need to Add to Your Diet

After declaring watercress the ultimate superfood, the CDC also highlighted other nutrient-dense vegetables that should be included in our diets: spinach, chard, and beet greens. These leafy greens are packed with vitamins A, C, and K, along with minerals like iron and calcium.Not only are they nutritious, but they also taste delicious, making them a great choice for adding variety to our meals and supporting our overall health.

Ultra-Processed Foods Have Been Shown to Decrease Lifespan

We've all heard that ultra-processed foods aren't the best choice for our health, and in 2024, scientists presented new evidence to support this. Diets high in processed snacks, frozen meals, and sugary drinks have been linked to shorter lifespans.The additives, preservatives, and excess sugar in these foods can take a toll on our long-term health. By being aware of the impact of ultra-processed foods and making healthier choices, we can improve our chances of a longer and healthier life.

Ginger Is an Anti-Aging Powerhouse That Targets 12 Hallmarks of Aging

After learning about the negative effects of ultra-processed foods, it's refreshing to discover a more positive story. A scientific review published in the journal Biomolecules showed that ginger targets 12 hallmarks of aging on a cellular level.From inflammation to oxidative stress, ginger offers a natural way to combat the signs of aging. Adding ginger to our teas, smoothies, or stir-fries can provide a boost to our health and help us age gracefully.

Washing Produce Will Often Not Remove Pesticides

While washing produce is important for removing dirt and bacteria, it doesn't always remove all pesticides. A 2024 report by Consumer Reports found that washing can only reduce pesticide residues to a certain extent.If you're concerned about pesticide exposure, peeling certain items or choosing organic produce when possible can be effective strategies to reduce your intake.

Can You Microwaving Plastic? Here’s What Toxicologists Have to Say

The answer is a resounding no. In 2024, experts like Phoebe Stapleton, Ph.D., emphasized that heating food in certain plastic containers can release harmful chemicals like BPA and phthalates into our meals.To avoid unnecessary exposure to these chemicals, it's best to use glass containers instead. This simple step can help protect our health and ensure the safety of our food.

The FDA Is Warning Against Drinking Apple Cider

There's nothing quite like a glass of apple cider on a fall day, but this year the FDA issued a warning. Unpasteurized apple cider can harbor harmful bacteria like E. coli and salmonella, posing a risk to consumers, especially those with weakened immune systems.Fortunately, there are plenty of pasteurized options available. Always check the label before buying to ensure the safety of your drink.
