Cleveland Cavaliers star LeBron James never played college ball, and he made clear in a press conference Tuesday that he's not a fan of the sport."The NCAA is corrupt," James said. "I'm sorry, it's going to make headlines, but it's corrupt.""I'm not a fan of how the kids don't benefit from none of this," he added.James also suggested that the NBA expand its developmental league, the G League, so it could one day become a viable option for top high school players who don't wish to play in college.He also implied he may not send his children to college if they wish to pursue basketball."It's kind of a fine line, because I have a couple of boys that could be headed in that direction. There's going to be decisions that we as a family are going to have to make," James said.  793

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 — Who’s been at a store buying holiday gifts and then the cashier asks, “do you want to sign up for our credit card today?” They might offer a discount or something else, but should you sign on the dotted line?“They make it easy. They really make it easy,” Leanne Smith said.Smith is from Solon and knows how stores can tempt you with their credit cards, but she’s sticking to her Target Red Card for now.“I don’t think it’s a responsible thing for me to have one at every store,” she said.Tedd Rossman from CreditCards.com said that if you ever plan on carrying a balance, store cards aren’t going to be the best option for you.“While sometimes these store cards can work for you, most of the time, they’re not the most consumer-friendly option,” Rossman said.That’s because Rossman says the average store credit card has an interest rate of 25%, some as high as 29.99% such as Discount Tire, Big Lots and jewelry store cards like Kay Jewelers.“These cards are not as selective about credit quality, which is why the retailers and their bank partners say they have to charge such high-interest rates,” Rossman said.CreditCardInsider.com recently rated various popular store cards based on various things like interest rates.Here are those results:Target - 24.4%Old navy - almost 26% (25.99%)Walmart - roughly 18-27% (17.99%-26.99%) interestNathan Grant from CreditCardInsider.com said you shouldn’t just sign-up at the checkout on a whim even if there’s a discount offered or cashback incentives.“The percentage of interest you’re paying might end up calculating to be more than what you got from spending on the cards,” Grant said.According to Grant, some of the better retailer cards are:Amazon prime cards with lower interest rates—5% back on Amazon purchases and gift cards when you sign up. Target—higher interest rate, but 5% back. And the only one rated excellent is Costco’s card, which has a 15% rate and various cash back options and good rewards on gas purchases.But keep this in mind: In a survey of nearly 3,000 shoppers nationwide, more than 40% said they regretted signing up for a retail credit card. Plus, one out of five in the survey said they carried a balance from the last holiday season, and more than 50% said they’ve paid interest on a retail store card.“That’s kind of like a wake-up call even to myself to be like I got to make sure that I’m always smartly shopping if I’m using credit cards,” Grant said.For Smith, she said she’s only carried a balance a couple of times in the past 20 years because she knows “if you can’t pay it, you really shouldn’t buy it just because you have a credit card.”Retail credit cards can give you benefits especially if you’re loyal to the business. It could help you build credit, but you’ll want to pay off your balances every month and spend responsibly.And another thing to watch out for is deferred interest. Even if you owe just one dollar by the time the term ends, you could end up paying interest on the entire amount you initially financed.This story originally reported by Jonathan Walsh on News5Cleveland.com 3102

Congress is currently honoring one of its own — longtime Georgia representative and Civil Rights leader John Lewis.Lewis' body was flown from Alabama to Washington, D.C. on Monday, and is currently lying in state in the U.S. Capitol Rotunda.Members of the House of Representatives and Senate will have a chance to pay their respects before a public viewing takes place this evening. Among those who paid tribute to Lewis with speeches were Senate Majority Leader Mitch McConnell, R-Kentucky and House Speaker Nancy Pelosi, D-California. CNN reports that the public viewing will take place outdoors due to the coronavirus pandemic.On Sunday, Lewis' body made a final trip over the Edmund Pettus Bridge in Selma, Alabama, where half a century ago, he led several marches for voting rights. The first of those marches became known as "Bloody Sunday," as Lewis and other civil rights activists were met with force from state and local police as they crossed the bridge. The marches sparked a national conversation about voting rights for Black people, and the Voting Rights Act of 1965 was passed a few months later.Following events in Washington, Lewis' body will return to Georgia — the state he represented in Congress for more than 30 years. Lewis' funeral will take place on Thursday at the historic Ebenezer Baptist Church in Atlanta — the same church that was formerly led by Dr. Martin Luther King, Jr.A public viewing at the Capitol building is one of the highest honors a Representative, a Senator or elected official can receive upon their death. Rep. Elijah Cummings, a fellow Civil Rights leader, and Congressman leader, was the last person to receive the honor upon his death in 2019. President George H.W. Bush and Sen. John McCain have also had public memorials at the Capitol in recent years.Lewis died on July 17 after a six-month battle with cancer. 1872
