Cyanide is a poison. Rattlesnake venom is a poison. Certain household products can be a poison. But coconut oil? One professor seems to think so, colliding head-on with consumers who believe it's good for them.In her lecture at the University of Freiburg -- entirely in German and posted in July -- professor Karin Michels, of the university's Institute for Prevention and Tumor Epidemiology, calls the health claims surrounding coconut oil "absolute nonsense" and says it's "pure poison" for its saturated fat content and its threat to cardiovascular health. The video of her lecture has amassed close to a million views and counting."Coconut oil is one of the worst things you can eat," Michels said.While others have taken a more measured view, they hardly buy into the ballyhoo. A 2016 survey in the New York Times suggested that 72% of Americans think coconut oil is healthy, versus only 37% of nutritionists polled."There are many claims being made about coconut oil being wonderful for lots of different things, but we really don't have any evidence of long-term health benefits," said Dr. Walter C. Willett, professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health, where Michels is also an adjunct professor."Coconut oil is somewhere in the middle of the spectrum in terms of types of fats. It's probably better than partially hydrogenated oils, [which are] high in trans fats, but not as good as the more unsaturated plant oils that have proven health benefits, like olive and canola oil," Willett previously told CNN.Health organizations tend to discourage the use of coconut oil, which is more than 80% saturated fat. The American Heart Association says it's better on your skin than in your food, and it recommends that no more than 5% or 6% of your daily calories come from saturated fats -- about 13 grams per day. The association also advocates replacing coconut oil with "healthy fats" such as polyunsaturated fats and monounsaturated fats, like those found in canola and olive oils, avocados and fatty fish.Coconut oil is "probably not quite as 'bad' as butter but not as good as extra virgin olive oil," Kevin Klatt, a molecular nutrition researcher at Cornell University who is studying the metabolic effects of coconut oil, previously told CNN.Klatt cautions that we should not develop too strong of an opinion of it without more data. "But at the same time, you have to be evidence-based ... and [currently], the evidence reflects benefits for olive oil, fish, nuts and seeds -- so that should be the focus in the diet."Coconut oil is extracted from the meat of the fruit. It contains mostly saturated fat, which is also found in large quantities in butter and red meat. Like other saturated fats, coconut oil increases LDL cholesterol, commonly known as "bad" cholesterol, which has been associated with increased risk of heart disease.But coconut oil also raises HDL, the "good" cholesterol, especially when replacing carbohydrates in the diet. This may be due to its high content of a fatty acid known as lauric acid. (This is also noted in Michel's statement summarizing her talk.)"Coconut oil is half lauric acid, which is a little bit unique," Klatt said, as the acid seems to raise HDL more than other saturated fats and is rarely found in such high amounts in foods.Still, though the increase in HDL seen with consumption of coconut oil may offset some of the disease risk, it's still not as good as consuming unsaturated oils, which not only raise HDL but lower LDL, according to Willett.Complicating matters is the fact that we still don't know for sure what exactly a high HDL translates to in terms of health risk. "There's been debate about the role of HDL," Willett cautioned. "Partly because there are many forms of HDL which have different health consequences ... which has made the water murky."For example, there are different forms of HDL that do different things. One role is to help take LDL cholesterol out of the bloodstream. "But some forms of HDL don't do that," Willett said, "so we don't know for sure that higher HDL is better."While an elevated LDL level is used as a marker for predicting cardiovascular risk and doesn't always translate to heart attacks, experts say it's still cause for concern.Research has found a mixed bag when it comes to saturated fats, and coconut oil in particular. A 2015 Cochrane review found that cutting back on saturated fats also lowered the risk of cardiovascular disease by 17% -- but it didn't change the risk of dying, and there was no benefit to replacing these fats with protein or starchy foods.Other research specifically on coconut oil has explored its effects on metabolism, appetite and cognitive function -- but "you can't infer from ... studies what coconut oil will and will not do. We need better controlled trials," Klatt said."Right now, the internet is jumping the gun and going way beyond the evidence."Like other oils, coconut oil is calorie-dense, which means consuming large amounts without reducing other calorie sources can lead to weight gain. Just one tablespoon has 120 calories, about the same as a large apple or four cups of air-popped popcorn."Oil is a really easy way to increase the energy density of a food. Things like almonds have a lot of fat, but it's easier to overeat pure oil than overeat pure almonds," Klatt said.In small amounts, however, coconut oil can have a place in one's diet. But for day-to-day use, experts recommend vegetable oils such as olive, canola or soybean oil, along with nuts and seeds, as a primary source of fats in the diet."It's not that you have to absolutely avoid coconut oil, but rather limit coconut oil to where you really need that special flavor, like for Thai food or for baking a special dessert," Willett said.Klatt agreed, saying that coconut oil "is certainly fine to consume occasionally, when a recipe calls for it."The-CNN-Wire 5933

COLUMBUS, Ohio — Imagine this scenario, or for some of you, it's been a past reality. You're in the shower and the water suddenly shuts off. You're covered in soap. You go into distress. Then rage overcomes you.In a Facebook post, Cody Vickers documented a similar scenario that happened in Columbus while he was at a construction job. His photo shows a butt-naked man bathing in water spewing from a broken water main near North High Street in Clintonville, the Columbus Dispatch reported.He said, “It’s not every day you see a naked man come out of his house screaming and cussing ... then comes off the porch and finishes taking his shower where the excavator hit the line," in a Facebook post that has since gone viral, getting 137,000 shares and more than 14,000 likes."I was in the f****** shower. I got soap all over me," said Vickers, repeating what the man said when he was met with a trench and a fountain of water. He said the man slung his towel off and ran down the steps, across the sidewalk and over the trench where he met his temporary shower.The Columbus Dispatch reported that the construction crew hit an unmarked line and the man came outside seconds later with a towel around his waist."I couldn't believe he did that. Dude had no shame," Vickers told WEWS. 1307

COVID-19 cases among younger Americans are on the rise, and while most under 45 who contract the virus will recover without significant complications, the virus is still a concern for anyone who gets it.But despite that concern, some students in Alabama are actively trying to come down with the coronavirus.According to officials in Tuscaloosa — the home of the University of Alabama — college students have been betting to see who can catch the virus first. Officials say that students put money into a pot, and the first one to contract the virus gets to keep the cash.Randy Smith, the Chief for the Tuscaloosa Fire Department, says he uncovered a major health concern involving area students and parties."We thought that was kind of a rumor at first," Smith said. "Not only did the doctors' offices help confirm it, but the state confirmed they also had the same information."Tuscaloosa City Councilmember Sonya McKinstry says it's up to young people to be responsible and avoid contact others if they're sick. She said the students' behavior is only slowing down a return to normalcy and putting the lives of their loved ones at risk."I just think it's senseless. I think it's careless. And it makes me mad as hell that you know we're constantly trying to do everything we can to slow the spread of the virus while they're just having a damn party trying to spread it," McKinstry said.The University of Alabama plans to reopen campus to students for in-person classes this fall. Officials have not said if the students hosting and attending the "coronavirus parties" are enrolled at the capstone.Young people in Alabama wouldn't be the first to hold "coronavirus parties." Earlier this year, Kentucky Gov. Andy Beshear reported that one his constituents contracted the virus at a similar party. 1807

CORONADO, Calif. (KGTV) -- Lifeguards in Coronado are on alert after spotting at least two juvenile white sharks Wednesday and Thursday. According to lifeguards, the sharks were at least a quarter to half a mile off the coast and didn’t appear to be engaging swimmers or showing signs of aggression. “Under existing protocol, the City was not required to close the beach or publicly report the sightings,” said City Manager Blair King. RELATED: 10 to 15 people stung by stingrays in Coronado“However, the City feels it’s important for the community to know that it takes these types of sightings seriously and is carefully monitoring the waters off Coronado. We also are working with Chris Lowe at the Shark Lab to find out more about the separate sightings and what might be going on.”Around 4 p.m. Thursday, a San Diego Fire-Rescue helicopter was called in and confirmed at least two four to five foot-long white sharks off the coast. The city says a lifeguard followed the sharks as they made their way to Point Loma. The city plans to try to tag or take DNA from the sharks over the weekend. According to city officials, it’s not uncommon to see juvenile white sharks offshore. “The shark population is rising and sightings are becoming more commonplace,” the city said in a news release. 1301
