Deep dives
Understanding Saturated Fat
Saturated fat's impact on health remains controversial. While some research suggests a link between high saturated fat intake and diseases like strokes and atherosclerosis, others argue for its benefits in brain health. The two types of saturated fats, even chain in red meat and odd chain in dairy, have different effects. Red meat consumption shows a correlation with cardiovascular disease, mainly attributed to components like heme, antibiotics, and trans fats, rather than saturated fat itself.
Endothelial Dysfunction and Heart Health
Plaque buildup in blood vessels is not primarily caused by saturated fat, but by endothelial dysfunction, involving the alteration of endothelium where lipoproteins accumulate. Insulin resistance and various lipoprotein species play significant roles in heart disease risk. Large buoyant LDL particles are neutral, while small dense LDL poses cardiovascular risks. Understanding lipoprotein species like ApoB can provide a better risk assessment for heart disease.
Importance of Omega-3 Fatty Acids
Omega-3 fatty acids, essential for brain health, are found in EPA and DHA from marine sources like wild fish. ALA, sourced from produce, is vital for cardiovascular health but lacks benefits for the brain. Vegans might require EPA and DHA supplementation. The quality of fish oil supplements is crucial, as farmed fish products contain high omega-6 levels, promoting inflammation. Consumption of wild fish is recommended for cognitive and neurobehavioral benefits.
In this informative and eye-opening podcast, I sit down with renowned endocrinologist and obesity expert, Dr. Robert Lustig, to discuss the often misunderstood topic of saturated fat.
Dr. Lustig breaks down the complex concept in a "beautifully simplistic" way and explains how the scale lies when it comes to measuring our overall health. We delve into the three separate fat depots in our bodies and how they contribute differently to our health.
Dr. Lustig also touches on the link between stress, cortisol, and visceral fat and how sugar plays a role in the development of a fatty liver.
