The study, presented over the weekend at the American College of Cardiology’s annual scientific session together with the World Congress of Cardiology, found that a keto-like diet may be associated with higher levels of “bad” cholesterol and twice the risk of cardiovascular events such as chest pain, blocked arteries requiring stenting, heart attacks and strokes.
The research team analyzed data from the UK Biobank, a large-scale database with health information from over half a million people living in the United Kingdom who were followed for at least 10 years. Upon enrollment in the biobank, participants completed a self-reported diet questionnaire and had blood drawn to check their cholesterol levels.
“Among the participants on an LCHF diet, we found that those with the highest levels of LDL cholesterol were at the highest risk for a cardiovascular event,” Dr. Iatan said. “Our findings suggest that people who are considering going on an LCHF diet should be aware that doing so could lead to an increase in their levels of LDL cholesterol. Before starting this dietary pattern, they should consult a health care provider. 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.”Popular keto diet may be linked to higher risk of heart disease, cardiac events — https://www.med.ubc.ca/news/popular-keto-diet-may-be-linked-to-higher-risk-of-heart-disease-cardiac-events/
