“In this Aliquot, I explain exactly what homocysteine is, how it impacts both cardiovascular and brain health, and how simple nutritional strategies—like supplementing with vitamins B6, B12, and methylfolate—can help bring levels down, supporting healthy aging and sharper cognitive function.”
“In this Aliquot, I'll explore how to recognize and address iron deficiency, the unique challenges of iron overload in aging, the ways alcohol may influence brain iron, and how infants tightly regulate iron as a built-in defense against infection.”
“In this Aliquot, sleep scientist Dr. Michael Grandner explains why sleep apnea is so often missed, how these nightly breathing disturbances affect the body, and which treatments can meaningfully improve sleep and long-term health.”
“The different stages of sleep provide crucial periods during which the body recalibrates to promote both mental and physical well-being. In this clip, Dr. Matthew Walker describes how the different stages of sleep influence emotional and cardiovascular health.”
“In this Aliquot, I explain why visceral fat behaves so differently from other fat, how it drives insulin resistance and chronic disease, and what research shows about the most effective ways to reduce it.”
“Time-restricted eating, which involves taking in food within a small window of time during the day and fasting for the remainder, can improve certain biomarkers of health – even without weight loss – to improve overall health. In Part I of this two-part segment, Drs.”
“Insulin-like growth factor-1, or IGF-1 for short, is a protein that plays critical roles in major growth pathways in the human body. It influences nearly every tissue in the body, especially developmental growth, skeletal muscle and neurons.”
“Recent discoveries in the field of epigenetics suggest we might be able to slow aging, based on the realization that not everyone ages at the same rate. Evidence suggests that drugs or other medical procedures can slow epigenetic aging, but other factors, such as diet and disease states influence it too.”
“The decline of deep sleep begins early in life, nearly disappears by age 80, increasing the risk for Alzheimer's disease. These Aliquot segments feature Dr. Charles Raison, a professor of psychiatry, and Dr. Matthew Walker, a professor of neuroscience and psychology.”
“Cholesterol is vital to human health, but an oversimplified view of cholesterol — that high-density lipoprotein (HDL) cholesterol is good, and low-density lipoprotein (LDL) cholesterol is bad — has led to a gross misunderstanding of the nuances that define the differences in cholesterol-containing lipoproteins.”
