Coronavirus pandemic safety measures have more Americans spending the traditionally family-and-food centric holiday of Thanksgiving in smaller groups or alone.If this is your first time attempting the big meal on your own, here are some basics and places to get help and advice.First figure out how much meat you’ll need, before you buy whatever turkey is left at the grocery store. Consider roughly one pound per person, this accounts for bone weight when buying the turkey. If you like a lot of leftovers, consider 1.5 pounds per person.If it’s just you and maybe one or two others, consider buying just a turkey breast. They are usually a few to several pounds each and are all white meat.You could also opt for a whole chicken instead; they are smaller but still give you the full bird experience with light and dark meat, legs, and a wishbone to snap.Before moving on, you should probably consider if you are comfortable cooking a turkey (or chicken) from raw. If not, that’s ok. Plenty of restaurants and grocery stores have done the cooking for you and will gladly deliver or have you pick up Thanksgiving meals for any size group.Once you have the right amount of meat, keep it frozen until a few days before you want to cook it, and then move it to the fridge to thaw.For what comes next, there are so many options for preparing and cooking a turkey, it’s hard to pick one way. While most agree the stuffing should not actually be stuffed inside the raw turkey, there are other questions - Foil on or off? Grill, oven or crockpot? Brine or no brine? Oil or butter?For help, step-by-step instructions, and ideas, here are some helpful links:10 Tips for cooking the perfect turkey from the Food NetworkBetty Crocker: How to cook a turkeyHow to cook a turkey, from the New York TimesPillsbury claims to have a no-fail methodAnd of course, there is the Butterball Hotline. A Thanksgiving tradition for first-time chefs across the country for almost four decades.The hotline has been answering chef’s questions since 1981. There is likely no turkey question they haven’t been asked before.Butterball offers turkey tips and tricks over the phone, by text message, live online chat, email and even through Amazon Alexa. And yes, they are helpful no matter what brand of turkey (or chicken) you are cooking.After all this work for the main dish, consider enjoying pre-packaged or heat-and-serve side dishes at Thanksgiving.If you are feeling adventurous and want to make sides, here are some helpful links:85 classic Thanksgiving side dishes from Delish - including sweet potatoes with marshmallows, green bean casserole, cranberries, and homemade cornbread.Best Thanksgiving side dishes from Good Housekeeping - including glazed carrots, buttermilk biscuits, squash soup, and rosemary rolls.Best of all, some of them can be made ahead and heated on Thanksgiving.Leaving you more time to explain to your extended family how to unmute themselves on your family Zoom call. (FYI, Zoom is lifting its 40-minute limit on free calls on Thanksgiving.) 3053

Conservatives now hold a decisive edge on the Supreme Court after the Senate voted in a near party-line vote on Monday to confirm Amy Coney Barrett to the highest court in the US.Republican-nominated justices hold a 6-3 advantage on the Supreme Court, three of whom are appointees of President Donald Trump.Trump hosted a swearing in ceremony at the White House nearly an hour after Monday's confirmation vote. Justice Clarence Thomas swore in Barrett.The lone dissenting vote came from Republican Susan Collins of Maine, who is facing a tough re-election bid for her seat. Collins expressed concern of holding a confirmation vote just eight days before the US presidential election. Also, one-third of all US Senate seats are up in next week’s election."Today, Monday, October 26, 2020, will go down as one of the darkest days in the 231-year history of the United States Senate," Senate Minority Leader Chuck Schumer said. "Let the record show that tonight the Republican Senate majority decided to thwart the will of the people and confirm a lifetime appointment to the supreme court in the middle of a presidential election after more than 60 million Americans have voted."In 2016, Republican senators opted not to consider President Barack Obama’s nomination of Merrick Garland to the court after the death of Antonin Scalia in February of that year.Senate Majority Leader Mitch McConnell defended his caucus' vote amid election season."In another political age, Judge Amy Coney Barrett would be getting 70 votes or more in the US Senate because of her qualifications," McConnell said. "In a different era. Now, we know that's not going to happen. These are not the days when Justice Scalia was confirmed 98-0 and Justice Ginsburg was confirmed 96-3. And by the way, I voted for both Ginsburg and Breyer. Seems like a long time ago now."In her swearing in ceremony, Barrett described the political battle during her confirmation. "I have spent a good amount of time over the last month at the Senate, both in meetings with individual senators and in days of hearings before the Senate Judiciary Committee," Barrett said. "The confirmation process has made ever clearer to me one of the fundamental differences between the federal judiciary and the United States Senate, and perhaps the most acute is the role of policy preferences." 2345

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

  

CORAL SPRINGS, Fla. — A copy of a school quiz entitled "Does Nikolas Cruz Deserve to Die?" recently gained a lot of attention on social media.The quiz was meant to be an assignment on the death penalty. School officials say it was distributed to students at Coral Glades High School in Coral Springs, Florida last week. The high school is just a few miles away from Marjory Stoneman Douglas High School where Cruz shot and killed 17 students and staff earlier this year.Stoneman Douglas parents like Cindy Levine are furious."These people lost their children, for crying out loud," Levine said. "And my son could have been one of them."The outrage spilled onto social media. Stoneman Douglas survivor and student activist Cameron Kasky, quoted in the quiz, tweeted "I cannot begin to express how pathetic I find this." School board critic Andrew Pollack, who lost his daughter in the school shooting, tweeted: "This is absolutely despicable." And, "Does anyone @browardschools have a brain?"School staff posted a message on the school website Friday saying they were unaware of the assignment.It said the material was from a subscription-based publication and has been pulled.The school said it's instituting a review and regrets the incident occurred.Scholastic, the publisher, sent WPLG a statement that their intention was to "... provide a platform for meaningful conversations around the history, civics and social impact of the death penalty. We deeply regret if this real life example added in any way to the ongoing suffering of the students, families and educators of the Parkland community." 1664
