The CANTOS Trial – Is Targeting Inflammation the Solution to Heart Disease?
The recently published results of the long awaited CANTOS trial may forever change our approach to the prevention and treatment of coronary artery disease (1). Inescapably, there is now proof that targeting inflammation, in this case by a drug, significantly improves outcome for certain very high-risk patients.

Can Low-Fat Be Salvaged? – An Update From the WHI Trial
A recent paper published in the American Journal of Clinical Nutrition provides updated results from the Women’s Health Initiative (WHI) Dietary Modification Trial (1). One of the questions raised is whether there is still hope for a low-fat dietary approach for the prevention of heart disease. The primary aim of the WHI Dietary Modification Trial was to […]
From Low-Fat, High-Carb to Insulin Resistance, Fatty Liver, and Heart Disease
I recently gave a talk at a meeting with colleagues, most of them cardiologists and endocrinologists, where I, among other things, discussed the current status of diet-heart hypothesis and the possible relationship between our fear of dietary fats and the obesity epidemic. After the meeting, a senior colleague of mine, an old friend, and mentor […]

Artificially Sweetened Beverages and the Risk of Stroke and Dementia
I’m often asked which is worse for health, sugar- or artificially sweetened beverages. My most common response is to recommend skipping both and choose water.

VLDL – The Role of Triglyceride-Rich Lipoproteins and Remnant Cholesterol
Knowing the role of VLDL (very low-density lipoprotein) and chylomicrons is a key factor in understanding how lipids (fats) and lipoproteins are involved in atherosclerotic cardiovascular disease (ASCVD). In the current era of adiposity and metabolic disease, VLDL has gained a bigger role than before and may help explain many of the disorders associated with the obesity epidemic such […]
Niacin (Nicotinic Acid, Vitamin B3) – Who Should Take Niacin?
