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

CLEVELAND — We’ve all seen shipping containers on the highway moving materials from one part of the United States to another. Now, Container Homes USA is converting those containers into mobile medical units that can be used to deliver COVID tests and vaccines to communities that need them.Inside, the containers are exactly as you’d expect a doctor’s exam room to look with cabinets for supplies, room for an exam table, and a bathroom in the back of the space. 471

"Obviously LinkedIn is a great platform to be on the professional side, but at the same time you really have to be careful with your social media."The experts say the first step in understanding what employers are seeing is to do the search yourself."Google yourself. If someone is going to Google you Google yourself so you know what's out there," said Marques "Lockdown your social media. Make sure everything is private so that you don't have people that could social media stalk you to get information on you for the job."Once you're comfortable with what the public can see on your digital platforms, employment experts urge job seekers to keep profiles and resume updated for the jobs they want."That's going to show the employer, one, the skillset that you have that relates to this position and also that you took the time to research it and change it to adapt to their company," said Marques.Here's your Rebound Rundown:- Be aware that employers will likely search for you and browse your social media as part of the hiring process- Search your own name and profiles to see what employers are seeing- Lockdown profiles and manage privacy settings- Keep your resume and professional profiles updated and specific to the jobs you desire.If you need help taking steps to prepare yourself for your next job opportunity, want to talk with experts, or need find other employment resources you can visit the Pikes Peak Workforce Center.This story was first reported by Patrick Nelson at KOAA in Colorado Springs, Colorado. 2385
