Drink Up: New Study Concludes Wine Can Offset Dementia

The health benefits of wine can sometimes be overstated by people who are a few glasses deep and slurring their words. Should you ever find yourself in a position to defend your moderate imbibing, you have supporting evidence: A new study says two glasses of wine daily can potentially reduce your risk of developing Alzheimer's.

The study, which appears in Scientific Reports, shows that wine has an effect on one's glymphatic function, or the way the brain removes toxins. To clear itself of damaging and accumulated proteins like tau and beta amyloid, which are often linked with dementia, the brain pumps in cerebral spinal fluid (CSF) to act as a flushing solution. All sorts of variables can influence the glymphatic system's operation, including trauma, stroke, and excessive alcohol intake.

But when researchers dosed the mice in the study with moderate alcohol—amounting to 2.6 drinks daily—the glymphatic system was more efficient, removing more waste and exhibiting less inflammation than the teetotaling control mice.

As is usually the case when it comes to booze, you can have too much of a good thing. When mice got the equivalent of 7.9 drinks daily, their glymphatic system grew sluggish until the overindulging was terminated.

"Studies have shown that low-to-moderate alcohol intake is associated with a lesser risk of dementia, while heavy drinking for many years confers an increased risk of cognitive decline," lead study author Maiken Nedergaard, of the University of Rochester Medical Center, said in a press statement. "This study may help explain why this occurs. Specifically, low doses of alcohol appear to improve overall brain health."

A Low-Carb Diet Could Shorten Your Lifespan

The Atkins, Paleo, and Keto diets may have different gimmicks, but they all share a common message: Carbs are bad and meat is good. Yet a new analysis reported by New Scientist suggests that anyone who buys into this belief may later come to regret it. According to the paper, published in The Lancet Public Health, people who eat a moderate amount of carbs actually live longer than those who avoid them.

For their study, researchers analyzed data previously collected from 15,400 participants in the U.S. They found that people who received about 50 to 55 percent of their calories from carbohydrates had the longest lifespans, roughly four years longer than those who got 30 percent or less of their energy from carbs.

This doesn't necessarily mean that the key to a healthy diet is to stock your pantry with pasta and croissants. The study also showed that people who got up to 70 percent or more of their energy from carbs died one year earlier on average than subjects in the 50 to 55 percent group. A closer examination at the eating of habits of people who ate fewer carbs revealed another layer to the phenomenon: When people avoided carbohydrates in favor of meat, their chances of early death rose, but the opposite was true for people who replaced carb-heavy foods with plant-based fats and proteins, such as nuts, beans, and vegetables.

These numbers point to something dietitians have long been aware of: Eating a diet that's based around animal products isn't ideal. Getting more of your protein from plant-based sources, on the other hand, can lower your blood pressure and reduce your risks of type 2 diabetes, heart disease, and certain cancers. Nonetheless, fad diets that forbid people from eating carbs while letting them eat as much steak as they want are still popular because they're an easy way to lose weight in a short amount of time. But as the research shows, the short-term results are rarely worth the long-term effects on your health.

Ocean Explorer Jean-Michel Cousteau's Tips for Dealing With Seasickness

Jean-Michel Cousteau—son of the iconic documentary filmmaker and conservationist Jacques Cousteau—claims to have never experienced seasickness himself. The 80-year-old explorer attributes his luck to the amount of time he's spent on boats filming nature documentaries, exploring marine environments, and raising awareness about conservation issues. So what advice does he have when his shipmates start to look a little green around the gills? Thrillist recently reached out to him for an answer.

Cousteau has seen a fellow sailor succumb to the nausea-inducing rocking of a ship many times. When this happens, he says the best thing to do is avoid the bow, or the front of the ship, but resist the urge to hide out below deck—away from any views of the ocean. Motion sickness occurs when the information sensed by our inner ear doesn't match up with what we see in front of us: In the case of sea travel, this could mean you feel the floor of the boat shifting beneath you while the wall of the galley appears to stay still.

Rather than forcing yourself to forget where you are, Cousteau says the most effective approach is to embrace your enemy. Look out at the water and try to appreciate the sights. Staring intently at the horizon will also help re-balance what you're seeing with what you're sensing. Soon you won't be focusing on that queasy feeling in your stomach. “Suddenly, instead of not feeling well, they’re distracted by our profound connection to the oceans," Cousteau told Thrillist.

And if all else fails and your boat is nowhere near dry land, Cousteau suggests a very Cousteau-esque solution: Slip on your scuba gear and get in the water. Of course, that may not be an option depending on what type of voyage you're on. If that's the case, you may want to consider these more conventional motion sickness remedies.
