Canadian Wildfires Map Shows Three US States Warned About Air Quality
Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content.
Canadian wildfires in Manitoba and Saskatchewan have prompted air quality alerts in Minnesota, Wisconsin and Michigan on Wednesday and Thursday as residents are advised to "limit prolonged or heavy exertion."
Why It Matters
The elevated levels of fine particulate matter resulting from wildfire smoke could present significant health risks, especially for people with asthma, heart disease or other preexisting respiratory conditions.
State and local health officials have urged those in the affected areas to limit outdoor activities and remain indoors while conditions persist.
Canadian wildfires have been of recent concern to Americans who live in bordering states, as hundreds of fires have burned this summer.
What To Know
According to the National Weather Service (NWS), all of Wisconsin and the majority of Minnesota and Michigan are under the air quality alert. The agency has a map on its website that lists regions directly impacted.
The NWS warns Wisconsin residents that "Northerly winds will continue transporting waves of heavy surface smoke from wildfires across Manitoba and Saskatchewan into Minnesota. Smoke will move south across all of Minnesota and linger through Saturday afternoon. The smoke will be reinforced by an area of high pressure that will create light winds and limit the dispersion of smoke."
People with lung and heart diseases including asthma are asked to avoid prolonged or heavy exertion while the general public is advised to limit it.
"Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Reduce vehicle trips and vehicle idling as much as possible," the NWS says.
People are also advised to keep their windows closed overnight to avoid smoke drifting into their homes.
Earlier in the week, portions of New York including New York City were under a similar alert related to the wildfires.
Below are the states currently impacted by the plumes of Canadian wildfire smoke:
What People Are Saying
NWS Weather Prediction Center Meteorologist David Roth to Newsweek via phone on Wednesday: "Behind the cold front from where the wildfires are in Canada there is bound to be a smoke plume--it was a bit more expansive today. Conditions across the three states should improve from Thursday afternoon onward."
Roth added, "Anyone who is sensitive to this should stay indoors and if outside they should wear a mask."
What Happens Next
Further advisories may be issued if wildfires in Canada continue to burn and wind patterns bring additional smoke into the U.S. A new weather front is expected to move in next week, which meteorologists say could shift air quality concerns across the Midwest and Northeast.
If smoke persists, health agencies recommend continued vigilance and adherence to advisories on minimizing outdoor activity and monitoring local air quality.

"Healthy" Habit Could Decrease Lifespan, Experts Say
Getting 10,000 steps a day. Improving your VO2 max. Putting berries on your breakfast. What are the habits you embrace in an effort to live a long, healthy life? Certainly it's the routines we do regularly that impact our health the most. But there's one well-intentioned habit in particular that longevity experts say can actually take years off your life instead of adding more to it: eating too much animal-based protein. Thought a high-protein diet was a good thing? As doctors explain here, getting too much can backfire. Why Overemphasizing Protein Isn't Actually Healthy Before we get into why too much protein isn't good for longevity, it's important to note that the nutrient is absolutely important. Dr. Suzanne J. Ferree, who is double-board-certified in family medicine and anti-aging and regenerative medicine, told HuffPost that it's especially important to get enough as we age. 'The common theory is that we need to cut protein-rich foods as we age, but the research actually only supports this in younger people, not in those of us over 50,' Ferree said. Scientific research backs this up, showing that older adults need more protein than younger adults because our bodies naturally lose muscle as we age. So yes, protein is absolutely important. How much protein a person needs each day varies based on one's individual health and needs, but the Food and Drug Administration recommends aiming for 50 grams of protein a day as part of a 2,000-calorie diet. The problem is that many people are eating more protein than they need. On top of that, Americans are overconsuming a specific type of protein that isn't all that healthy. In general, there are two types of proteins: animal-based proteins and plant-based proteins. Research has shown that plant-based proteins are healthier than animal-based proteins. Unfortunately, Americans are consuming more of the latter than the former. 'A common mistake is the overemphasis on consuming a high-protein diet, particularly one rich in animal-based proteins, with the belief that it is essential for longevity and muscle preservation. Many people assume that the more protein they consume, the healthier they will be, leading to an overconsumption of animal products like meat, dairy and eggs,' said Dr. Monisha Bhanote, a quintuple-board-certified physician and longevity expert. Most Americans are eating about 100 grams of protein a day, double the recommended amount. According to a Dietary Guidelines for Americans report, 75% of Americans meet or exceed the recommendation for meat, poultry and eggs. Bhanote says this is exactly what can take years off one's life. 'Excessive consumption of animal-based proteins can actually accelerate aging and undermine cellular health, contrary to popular belief,' she said. She explained that the biggest reasons for this come down to two harmful compounds: advanced glycation end products (AGEs) and trimethylamine N-oxide (TMAO). 'AGEs are harmful compounds that form when proteins or fats combine with sugar in the bloodstream,' Bhanote said. She explained that animal-based foods — especially if they are grilled, fried or roasted — are high in AGEs. Research shows that these compounds can accumulate in your tissues and, over time, can lead to oxidative stress and inflammation, which are key drivers of cellular aging. 'AGEs damage proteins, DNA and other vital cellular structures, accelerating the aging process and contributing to chronic diseases like diabetes, cardiovascular disease and Alzheimer's,' Bhanote said. What about TMAO? Bhanote explained that elevated levels of TMAO have been linked to an increased risk of cardiovascular diseases, including atherosclerosis, heart attack and stroke — all of which obviously are not good for longevity. 'TMAO promotes the accumulation of cholesterol in the arteries and impairs the body's ability to remove it, leading to inflammation and further damage to the cardiovascular system. This not only compromises heart health but also affects overall cellular function and longevity,' Bhanote said. Related to the mistake many people make of overemphasizing protein in their diet, Raghav Sehgal, a Ph.D. student and Gruber fellow at Yale University whose research focuses on human aging, told HuffPost that one common mistake people make when it comes to longevity is focusing on 'miracle diets' promising fast results. The biggie that's relevant here: the ketogenic diet, which prioritizes fat and protein while minimizing carbohydrates. For many people doing keto, meat and eggs are hero foods; however, as previously explained, eating too many animal products can take years off your life. So, how should we approach protein with an eye toward longevity? Bhanote and Sehgal are of the same mind about this: Eat more protein-rich plants and fish. While fish certainly isn't a plant, it is thought of differently than animal-based proteins because it has a completely different nutritional makeup than meat, and scientific research has repeatedly shown benefits to human health when consumed regularly. Eating fish regularly has been associated with reducing the risk of premature death by 12%. Sehgal explained that plant-based proteins (such as beans, lentils, chickpeas, soy, nuts and seeds) are loaded with antioxidants, fiber and nutrients that keep our hearts healthy, reduce inflammation and lower the risk of chronic diseases. 'These foods are naturally low in AGEs and do not contribute to TMAO production, making them much gentler on your cells and overall health,' Bhanote added. Scientific studies show that having a diet that prioritizes plant-based proteins lowers the risk of mortality associated with cardiovascular disease and other causes. In other words, replacing animal proteins with plant proteins can add years to your life. While most Americans meet or exceed the protein recommendation for meat, poultry and eggs, 90% of Americans aren't meeting the recommended guidelines for seafood. Sehgal told HuffPost that seafood high in protein and unsaturated fats supports brain health, promotes hormone balance and helps fight inflammation — all of which contribute to longevity. Again, no one is disputing that protein is important. It's crucial to get enough and, as Ferree pointed out, it's especially important to get enough as we age. But other nutrients are important too, which is why Sehgal said the best diet for longevity is a balanced one that includes a wide variety of nutrient-rich foods. The benefit of eating a balanced diet full of plants certainly isn't revolutionary news, but it is backed up by many scientific studies. When it comes to longevity — and health in general — science-backed wins out over trendy and new. HuffPost.

This Oil May Help Lower Cholesterol—Here's What a New Study Says
Reviewed by Dietitian Mandy Enright, M.S., RDN, RYTKey Points Having high blood lipids, which includes LDL cholesterol, is a risk factor for heart disease. This study suggests that ingesting extra-virgin olive oil daily may improve cholesterol levels. EVOO with higher antioxidant levels seemed to be most heart disease is the No. 1 killer of Americans, it is also possible to prevent it. The American Heart Association promotes tips for prevention with its Life's Essential 8, eight areas that influence heart health—four of them health behaviors and four of them measurable health factors. The behaviors include eating a heart-healthy diet, engaging in regular physical activity, quitting tobacco and getting healthy sleep. The other factors include managing weight, cholesterol, blood sugar and blood pressure. Many studies have indicated that olive oil may help promote a healthy cardiovascular system. This is partly due to its heart-healthy monounsaturated fats. But there's another component of olive oil that may also play a heart-healthy role: polyphenols. Polyphenols are powerful plant compounds that exhibit antioxidant properties. Scientists in Greece wanted to take a closer look at the polyphenols in extra-virgin olive oil (EVOO), comparing the benefits of two EVOOs with different levels of polyphenols. Their results were published in Nutrients. Let's break down what they found. How Was This Study Conducted? Researchers recruited two groups of people—one group had hyperlipidemia (high blood lipids, including LDL cholesterol), and the other was a 'healthy' group without hyperlipidemia. The hyperlipidemia group had 24 men and 26 women with an average age of 52; the healthy group had 8 men and 12 women with an average age of 49. Researchers split the hyperlipidemia group in half, with one half receiving an extra-virgin olive oil with high phenolic content and the other using an extra-virgin olive oil with lower phenolic content. Still, the group taking the extra-virgin olive oil with lower phenolic content took a higher dose of it so that each group's total daily phenolic content from extra-virgin olive oil was equal. The healthy group consisted of 20 individuals who were gender-matched to participants in the other two groups. This group also took either the high- or low-phenolic EVOOs in the same dosages as the hyperlipidemia participants. The reason for this 'healthy' group was to see if there were any differences in their blood lipids at the end of the study period, which lasted for four weeks, and to compare the healthy group's changes in bloodwork to the hyperlipidemia groups' changes, including differences between genders. All participants were instructed to take the olive oil on an empty stomach for faster absorption of the polyphenols, and to continue with their regular diet and activities. They were also asked to not add any supplements or foods high in polyphenols that were not already a part of their normal routine. What Did This Study Show? At the end of the four weeks, 22 participants in the lower-phenolic group and 28 in the higher-phenolic group had made it to the end of the study period with a 100% adherence rate. Researchers found that the hyperlipidemia group had greater improvements in blood lipids compared to the healthy group. Specifically, they found that HDL cholesterol—which is the beneficial type of cholesterol—increased, and lipoprotein (a), also called Lp(a) and similar to LDL cholesterol, decreased slightly in the hyperlipidemia group, but not in the healthy group. Even though both groups had equal daily phenolic content from olive oil, the group that ingested the higher-phenolic EVOO showed significant improvements in total blood cholesterol compared to the group that consumed the lower-phenolic EVOO at higher doses. This study does have several limitations, including the small sample size and short study duration. The participants were also from the region in Greece that grows the specific type of olive that was used to make these extra-virgin olive oils, so it is unknown whether these results can be generalized to other populations in other parts of the world. Additionally, researchers did not gather dietary information from participants, so it's unknown what other foods rich in polyphenols they were consuming. Researchers also cannot be confident that the healthy fats in the olive oil didn't contribute to these results. How Does This Apply to Real Life? Olive oil is one of the staples of the Mediterranean diet. That's because it's been shown time and time again to support overall health and lower the risk of certain diseases, including heart disease. Research also suggests that it may lower the risk of dementia-related death. Some folks even take a shot of the heart- and brain-healthy oil every morning, touting extra-virgin olive oil's anti-inflammatory properties. And while you certainly could do a shot of straight up EVOO each morning, cooking meals and snacks with olive oil throughout the day might be a more palatable option. We love using olive oil in dressings, like our Citrus Vinaigrette or Basil Vinaigrette. You can create a flavorful dipping oil for your favorite bread by adding herbs and spices to extra-virgin olive oil—or use it to drizzle over veggies. And if you have a bounty of yellow squash or zucchini, you'll want to try our Olive Oil-Braised Summer Squash. It's important to note that this study used extra-virgin olive oil, not regular olive oil, which is lighter in color and flavor. EVOO is a higher quality oil, while regular olive oil is more refined and neutral in flavor (kind of like canola or vegetable oil). EVOO has to meet more rigorous standards and has more polyphenols—so if you want to up your intake of those, go for the EVOO. Following a Mediterranean diet eating style makes it easy to incorporate more extra-virgin olive oil into your life. We have several Mediterranean diet meal plans to choose from, depending on your goals. So whether you want more energy, healthier blood pressure or just want to age gracefully and healthfully, we've got a plan for you. Our Expert Take This study suggests that taking extra-virgin olive oil on an empty stomach in the morning may help improve blood lipids. While it's not harmful to ingest EVOO straight with no food, it might not be palatable to some. Find ways to incorporate this healthy oil into your recipes—like we do with our simple Pesto Scrambled Eggs or Pasta al Limone. You can even add a shot of it to your morning smoothie, or simply drizzle it over bread, veggies and pasta. Read the original article on EATINGWELL

After deep DOGE cuts, National Weather Service gets OK to fill up to 450 jobs
The National Oceanic and Atmospheric Administration will hire as many as 450 people to shore up the National Weather Service after deep cuts in the spring raised concern about dangerous understaffing, the Trump administration confirmed Wednesday. NOAA was granted permission to fill crucial positions at its weather arm, including openings for meteorologists, hydrologists and electronics technicians, Trump administration officials said. The hirings are part of an exemption to a freeze on federal hiring that is in place through at least Oct. 15. NOAA declined to comment further. The planned hiring was first reported by CNN. President Trump's Department of Government Efficiency has gutted NOAA and the National Weather Service, which are key for the nation's daily weather forecasts, severe storm warnings, climate monitoring and more. Hundreds of NOAA forecasters and other employees have been laid off, and weather service offices around the country have had a number of vacancies. The administration has also weighed ending the sharing of satellite data that are key to effective storm tracking and stopped tracking the cost of climate change-fueled weather disasters. Meteorologists and climate scientists have warned of consequences with fewer workers in positions that are crucial, especially as the hurricane season got underway. After deadly flash flooding that killed dozens of people in Texas last month, some local officials and Democrats suggested that the deep staffing cuts may have contributed to endangering lives, though others defended the agency's work. Experts cautiously applauded the hiring exemption as positive news. 'While this new development is great news for the NWS and the American public, I would like to see that the hiring actions are actually underway,' said Louis Uccellini, former NOAA administrator for weather services and weather service director. The hirings are said to include the 'mission-critical field positions' that the agency announced it would hire for in June 'to further stabilize front line operations.' The agency did not say at the time how many roles would be filled. St. John writes for the Associated Press.
