Could the no-calorie sweetener you rely on to replace sugar in your diet actually cause weight gain instead of the weight loss you were expecting?The answer may be yes, according to a new study."Artificial sweeteners are not risk-free," said Brian Hoffmann, assistant professor in the Department of Biomedical Engineering at the Medical College of Wisconsin and Marquette University, and a lead author of the study. "They are a very controversial topic when it comes to health and nutrition ... but they're so prevalent in society that I think we owe it to ourselves to try and figure out what's actually going on."Hoffmann presented his new research Sunday at the annual?Experimental Biology meeting in San Diego. Relying on rats and human cell cultures, his team identified a number of pathways linking artificial sweeteners with metabolic changes at the genetic level that could lead to diabetes and obesity. Specifically, the researchers found that three weeks of exposure to aspartame and acesulfame potassium -- two artificial sweeteners frequently combined in products such as Equal -- altered the expression of certain genes responsible for lipid metabolism in the cells of both rats and humans."Aspartame had some significant changes, and one of those was an increase in lipids in the bloodstream and a decrease in a biomolecule that is involved in clearing (lipids) from the bloodstream. And we saw the exact same thing with the acesulfame potassium," Hoffmann said."We then took those particular sweeteners and put them on endothelial cells -- the cells that line the blood vessels and would be exposed to them in the body -- and we detected a marked dysfunction, suggesting why sweeteners and diet soda have been linked to potential cardiovascular problems," he added.What was perhaps most surprising, according to Hoffmann, was that these metabolic changes did not occur in the presence of natural sugars such as glucose and fructose. This suggests that artificial sweeteners could contribute to metabolic disorders such as diabetes and obesity by an entirely different mechanism than natural sugars, he said.Artificial sweeteners appear to contribute to metabolic disorders by altering the activity of certain genes responsible for the breakdown of macromolecules such as fats and proteins, Hoffmann said. This is different from normal sugars, which contribute to cardiovascular disease through insulin resistance and by damaging the cells lining the body's blood vessels."People are generally consuming non-nutritive sweeteners believing they are a 'healthy choice,' but this may not be true," said research scientist Meghan Azad of the University of Manitoba in Winnipeg, who was not involved in the new study."This is especially important given the widespread and increasing consumption of artificial sweeteners in the general population and the increasing use of artificial sweeteners in our food supply," said Azad, who has authored a paper that reviewed a number of studies on the potential downside of artificial sweeteners on weight and health.According to Azad, over 40% of adult Americans consume no-cal sweeteners on a daily basis, and studies that measure the sweeteners in blood and urine show that many people who report not using artificial sweeteners are unknowingly consuming them.It's the latest assault in the ongoing debate over artificial sweeteners and their impact on health -- a debate that began when one of our most popular foods, sugar, turned sour in terms of health. 3527

Customers of Comcast’s Xfinity internet service in many states may find that they will be charged if they use a lot of internet at home.The news comes as many Americans are working, schooling and using the internet to watch TV programs through the internet.Comcast will begin limiting many customers to 1.2 terabytes of internet data per month before charging overages. Beginning in December, Comcast says it will begin offering an unlimited plan for customers who plan to use that much data. For most customers who rent a gateway from Comcast, an unlimited plan would cost an additional a month, while most other customers would pay an additional a month. Comcast will implement the plans for customers in the states of CT, DE, MA, MD, ME, NH, NJ, parts of NC, NY, parts of OH, PA, VA, VT, WV, and the District of Columbia.The cap will not apply to the Gigabit Pro tier of service or business internet customers.For those who use more than 1.2 terabytes of data per month, Comcast will charge for every 50 gigabytes of additional data. The overages will be capped at 0 per month.Comcast says it will notify customers when they're nearing their data limit, and will send those notifications at 75%, 90% and 100% usage.Comcast says only 5% of its customers exceed 1.2 terabytes of data per month. Before the pandemic, Comcast suspended caps on internet usage as more Americans began using the internet for work and school.Those who stream TV might be most likely to go over the cap. According to Netflix, one hour of video can use up to 7 gigabytes of data. Someone who streams six hours a day without using any additional internet could use up an entire month’s worth of data. However, Comcast refutes those estimates and says that 1.2 terabytes cover as many as 500 hours of streaming video. More details can be read here.Editor's note: An earlier headline on our article erroneously classified the new policy as an "internet usage cap" and has since been changed. The earlier version also stated that customers will receive a notification when 90% of their data is used. It has been updated to reflect they will also receive notifications at 75% and 100% use. Additionally, a clarification was added to reflect customers can purchase unlimited plans in December. 2287

CORONADO, Calif. (KGTV) -- Warmer water temperatures are bringing out the stingray encounters in San Diego. Thursday afternoon, 12 more people were stung just days after a similar incident involving 10 to 15 people Tuesday. “I’m not used to the beach I come from Arizona so like this is actually happening,” said Angelo La Rosa, who is visiting from Arizona. “It felt like something was digging into my skin,” said 13-year-old Phoenix Stofa, who was one of at least a dozen stung Thursday. RELATED: 10 to 15 people stung by stingrays in Coronado“Yeah, yeah they don’t want to get stepped on and that’s their only defense mechanism and they have a barb,” said Sgt. Damon Bassett, a lifeguard in Coronado. Basset said he feels for those who get stung. “Anytime you get some nice weather and some warm water people don’t know to shuffle their feet. Then they can come in contact and get stung.”“Don’t walk on the water like you would on land,” Bassett added. A painful lesson for some, but still a day at the beach. “I just thought of the shark movies but it wasn’t a shark alert it was just a stingray. If it was a shark alert, I would have been more,” La Rosa said. If you do happen to get stung, lifeguards say you should soak the affected area in hot water to deactivate the venom. 1291

Consumers can consider many factors when evaluating an airline, but getting you where you’re going on time, not losing your checked bag, and giving you no reason to lodge a formal complaint seem like decent baselines.Fortunately, the government requires the nation’s largest dozen commercial airlines to report statistics on just those things.The Air Travel Consumer Report, released by the Department of Transportation, measures not only performance of major U.S. airlines such as American Airlines, Delta Air Lines and United Airlines, but also regional carriers such as ExpressJet and SkyWest, which are contracted to fly short routes to and from hubs of those big airlines. Here’s how airlines measured up in 2017, according to the report.On-time rates 784
