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.”
Amazon plans to launch its first prototype satellites for Project Kuiper, an internet-from-space venture, in 2022. It's the first major step in the e-commerce giant's plan to rival SpaceX by building a network of satellites in space, providing internet to rural, underserved communities around the world. Loren Grush, senior science reporter for the Verge, discusses the project and how it could transform internet access moving forward.
The FDA is assessing whether the Moderna vaccine can cause heart problems in adolescents. Professor Peter Pitts, founder of the Center for Medicine in the Public Interest and former FDA Associate Commissioner, discusses what the FDA is looking into and what it means for the millions of kids yet to be vaccinated.

Leaders around the world have come together to discuss plans to bring action towards the Paris Agreement along with solutions on how to solve the evolving climate change crisis at the COP26 Summit. President and CEO of Center for International Environmental Law Carroll Muffett, joined Cheddar to discuss more.
Rachel Cleetus, the policy director and lead economist of the climate and energy program for the Union of Concerned Scientists, joined Cheddar to break down some of the key goals from the COP26 summit and why leaders must focus on the science of climate change instead of getting bogged down by petty politics and the fossil fuel industry. "The main thing they have to do, make sure we're cutting our emissions sharply within this decade because the science shows that we have to cut global emissions in half by 2030 if we're going to meet our goals of averting some of the most catastrophic impacts of climate change," she said.
Coastal cities around the world are grappling with sea level rise. And building a seawall? Not so fast. While a sea wall can be effective in certain scenarios, it can make the effects of sea level rise worse. That’s why municipalities are looking into creative alternatives.
