Read on to learn why iron overload promotes the development of diabetes and heart disease and how iron reduction strategies can be used to beneficially alter the course of these diseases. September 20, 2017The Gut–Heart ConnectionAs the prevalence of heart disease continues to rise, researchers are hard at work trying to discover the mechanisms at play. One factor to emerge in recent years is the gut and its associated microbes. Read on to learn how gut ecology can influence heart health and heart disease. June 7, 2017Does Testosterone Therapy Increase The Risk of Heart Disease in Men?In recent years, advertising campaigns for testosterone replacement therapy have sparked a rapid rise in the use of testosterone gels, patches, pellets, and injections by men of all ages. Despite its popularity, testosterone therapy is not without risk. Research suggests that men who use testosterone may be at increased risk of heart disease.

May 17, 2017A Functional Perspective on Diet and CholesterolFor nearly 50 years, cholesterol and saturated fat have been maligned by the medical community for their purported role in heart disease. However, a large body of scientific research indicates that dietary cholesterol and saturated fat are not the driving forces behind heart disease. Despite this evidence, much of the medical community continues to promote outdated dietary guidelines for patients with high cholesterol and heart disease, including low-fat and low-cholesterol diets. As it turns out, this outdated advice may actually be harmful to the heart! Read on to learn why dietary cholesterol and saturated fat are not to blame for high cholesterol and heart disease and why a reduced-carbohydrate, nutrient-dense diet is the healthiest approach for treating high cholesterol and heart disease.

November 30, 2016The Diet-Heart Myth: Statins Don’t Save Lives in People Without Heart DiseaseCardiovascular disease is one of the most misdiagnosed and mistreated conditions in medicine. In the first article in this series, I explained it’s not the amount of cholesterol in the blood that drives heart disease risk, but the number of LDL particles. In the second article, I discussed the five primary causes of elevated LDL particle number. In this article, I will debunk the myth that statin drugs save lives in healthy people without heart disease, and discuss some of the little known side effects and risks associated with these drugs. November 28, 2016What Causes Elevated LDL Particle Number?In the last article in this series, I explained that LDL particle number (LDL-P) is a much more accurate predictor of cardiovascular disease risk than either LDL or total cholesterol. In this article, I’m going to briefly outline the five primary causes of elevated LDL-P. November 23, 2016RHR: Does your diet affect your cholesterol level?Today’s topic and today’s big question is, if dietary fat and cholesterol don’t raise cholesterol levels, why do total cholesterol levels drop after you stop eating those foods? That’s a really good question, and for all of the discussion about this topic, this is actually how I got started in blogging and writing. Way back in the Healthy Skeptic days, I started writing articles about the relationship between cholesterol and saturated fat and heart disease. It’s been a dominant theme of my work since then. There are lots of other people who are writing and speaking about this, and there’s still quite a bit of confusion out there, and it’s understandable because this can be a confusing subject. November 14, 2016The Diet-Heart Myth: Why Everyone Should Know Their LDL Particle NumberCardiovascular disease is one of the most misdiagnosed and mistreated conditions in medicine. In this article, I will debunk the myth that high cholesterol in the blood is the cause of heart disease.
