what's got us buzzing Is the erythritol health scare just hype? It's white, granular, and popular with bakers, but it's not sugar. Erythritol is a popular alternative to old-timey sweeteners like saccharin and acesulfame-K. ($210 million of the stuff was sold globally in 2022 — that's around one-tenth of the sweetener market.) Super low carb and about 70% as sweet as sugar, erythritol has become especially common in keto desserts. Thanks to erythritol, you can literally have your sugar-free cake and eat it too. So, I can only assume it came as quite a jolt to many low carb fans when new research surfaced this month that suggested that far from helping you and your heart into a healthy old age, erythritol may increase the risk of heart attack and stroke. I confess, I eyed a pot of Truvia in my kitchen with new suspicion, even considered tossing it in the garbage. But then I decided to take a closer look at the findings. One of the study's worrying findings was that erythritol had a blood clotting effect, (blood clotting is a common risk factor for stroke). However, this was only found in a test tube. More research is needed in real, live human beings to better understand the significance of this finding. What about the other claim that a high level of erythritol in the blood was linked with increased risk of heart attacks? Surely that's a major concern? The problem is that it's difficult to be certain that it's erythritol that's harming heart health because many of the 4,000 people involved in the trial had existing cardiovascular disease or other risk factors. It's possible that high levels of erythritol in the blood were a symptom of a problem that may lead to a heart attack, not the cause. More research on the nature of the relationship is needed. If you want to avoid sugar (which has strong links to all kinds of health issues) but have been put off of erythritol by this research, there are many delicious alternative sweeteners to spoon into your morning coffee. But I'm going to stick with it for now. tl;dr: A popular sweetener, much beloved of the keto crowd, found itself in the health scare spotlight this month. However, given that harmful effects on the blood were only found in lab conditions, and the link with real heart attacks isn't clear cut, how serious the risk is remains unclear, especially if you don't consume a whole lot of it.

Weird Science Is seaweed about to become the new kale (but better)? Ready to dive into a world of algae and seaweed foodstuffs? There's more to them than a tasty sushi wrap — they're also a nutritional powerhouse and an eco-friendly food source. Algae and seaweed are rich in vitamins and minerals, making them a fantastic addition to any diet, according to Dr. William Sears, pediatric and family medicine practitioner and author. "There are thousands of species of algae and each one produces lots of healthy nutrients we all need, but most of us don't eat enough of them," he notes. "They're a rich source of B vitamins, vitamin K, iron, magnesium, calcium, iodine, and more." They're also a great source of plant-based protein, making them an ideal food for vegans and vegetarians. According to Dr. Stephen Mayfield, a professor of biology at the University of California, San Diego, director of the California Center for Algae Biotechnology, and senior author of the study "Developing Algae as a Sustainable Food Source," algae are, biochemically speaking, a superfood. "Part of that is because algae don't have to have stems, roots, or branches to hold themselves up, so they dedicate all of their energy to making more protein, fatty acids, etc," Mayfield explained. The real kicker? Algae and seaweed could be the key to sustainable agriculture. Unlike land-based crops, seaweed farming doesn't require fertilizers, pesticides, or even fresh water. It's a low impact and sustainable food source that could help feed the world's growing population while reducing our environmental impact, fighting climate change, and improving water quality one frond at a time. Next time you're looking for a healthy and sustainable food option, consider incorporating algae and seaweed into your diet. Whether you're snacking on crispy seaweed chips or blending up a spirulina smoothie, you'll be doing your body and the planet a favor. Stay seaweed savvy, folks!

Health Hype Answer Could a racing heart trigger anxiety? Yes! A recent study revealed that mice may become anxious due to an increased heart rate, suggesting that emotions can arise from the body as well as the brain. Researchers used optogenetics to manipulate heart rate in mice and measure their behavioral responses. They bioengineered muscle cells in the rodents' hearts to make them sensitive to light and fitted them with tiny vests that emitted red light to control their heart rate. While we can't be sure if this study translates to humans, it does suggest that our minds and bodies are interconnected differently than we thought. Next time you feel your heart racing, take a deep breath and remember that it's all just part of the mind-body connection. And if you happen to see a mouse scurrying by, give them a little wave and say thanks for the scientific insight!
