A new study from the American College of Cardiology has found that the popular ketogenic or "keto" diet may contribute to higher levels of "bad cholesterol" and a twofold increase in the risk of heart attacks and strokes.
“Our study found that regular consumption of a self-reported diet low in carbohydrates and high in fat was associated with increased levels of LDL cholesterol— or “bad” cholesterol—and a higher risk of heart disease,” said Dr. Iulia Iatan, MD, PhD, lead author of the study and attending physician-scientist at the Healthy Heart Program Prevention Clinic in St. Paul’s Hospital.
“To our knowledge, our study is one of the first to examine the association between this type of dietary pattern and cardiovascular outcomes.”
The study points out that depriving the body of carbohydrates such as bread, pasta, and rice forces the body to break down fat for energy instead. This breakdown produces ketones in the liver, hence the name keto. Advocates for this type of diet suggest obtaining 60 to 80 percent of calories from fat.
By comparing this low-carbohydrate, high-fat (LCHF) diet with a more standard diet, the study found that it elevated levels of LDL cholesterol in some people, which is known to elevate the risk of heart disease.
Before starting this dietary pattern, they should consult a healthcare provider," Iatan said. "While on the diet, it is recommended they have their cholesterol levels monitored and should try to address other risk factors for heart disease or stroke, such as diabetes, high blood pressure, physical inactivity and smoking.”
Schools across the country are determined to keep class in session, despite the rapidly-spreading Omicron variant. While many parents prefer in-person learning, they also worry whether the current public health guidelines will be enough to protect their kids. Erin Richards, national education reporter for USA Today, joined Cheddar to discuss how are schools are preparing for the surge to avoid another round of remote learning.
With the annual CES convention underway amid COVID, HP unveiled rolled out a number of new products virtually this year, including new gaming PCs and 4K display monitors. But as industries look toward a greener future, HP is working with the climate crisis in mind. James McCall, chief sustainability officer at HP, joined Cheddar's Kristen Scholer to discuss the company's climate goals, which includes reducing its carbon footprint to net-zero by 2040. He admitted that reaching the ambitious goal will be difficult because much of the company's emissions totals come from third parties. "A large part of our footprint is outside of HP's direct control. A lot of it comes either from our incoming supply chain, the materials, our manufacturing process, or about 30 to 40 percent of it comes from our consumer-use base," McCall told Cheddar.
Pfizer and BioNTech are working to develop an mRNA-based shingles vaccine following the success of the COVID-19 shot. This latest collaboration will mark the third time the pharmaceutical companies have worked together on a vaccine.
The potential collapse of the Thwaites glacier in Antarctica has been deemed a potential "doomsday event" — researchers and scientists say its melting and collapse could raise global sea levels by at least two feet, enough to destroy coastal communities around the world. One team of scientists is traveling to the Thwaites glacier to drill below in order to gauge current ocean temperatures and attempt to model possible outcomes. David Holland, professor at NYU and Principal Investigator for the International Thwaites Glacier Collaboration, joins Cheddar Climate to discuss the glacier's potential collapse, his team's research plan, and more.
As winter break wraps up and COVID-19 cases hit record levels, the majority of school districts are returning to in-person classes. While some public schools in large cities have shifted to remote learning for the beginning of the year, the schools that are reopening campuses are determined to avoid the academic, social, and logistical challenges that come with a virtual classroom. Cheddar News is joined by Keith Powers, NYC Council Member, to discuss.
With a rising number of COVID-19 cases due to the omicron variant, the FDA is making big moves. First, Pfizer's COVID-19 booster has been authorized for those ages 12 to 15. The agency also reduced the amount of time to wait between receiving a second vaccine dose and booster from six months to five. Finally, a third primary series dose of Pfizer's shot is approved for immunocompromised children five to 11 years old. Professor Peter Pitts joins Cheddar News to discuss.
California's new composting law will affect what residents do in their kitchens. As of this week, Californians will have to recycle excess food in an effort to reduce emissions caused by food waste. Cities and counties will turn recycled food into compost or use it as a renewable energy source. California's new law is the largest mandatory residential food waste recycling program in the country. Rachel Wagoner, Director of the California Department of Resources, Recycling and Recovery called the law 'the biggest change to trash' since recycling started in the 1980s. She joined Cheddar Climate to discuss.
Deborah Brosnan, President of Deborah Brosnan & Associates, joins Cheddar Climate, where she explains why global warming brought about 'a year of reckoning' in 2021 and why previously unprecedented weather events could become the norm going forward.
