In this episode, I’m joined by cardiac dietitian Michelle Routhenstein to unpack why heart disease prevention is still so misunderstood. We explore cholesterol confusion, blood pressure, saturated fat, carbs, supplements, and why personalised nutrition matters far more than rigid dietary rules.

Michelle explains how food choices influence plaque progression, inflammation, gut health, and heart rhythm, and why sustainable habits, not extremes, are key for long-term cardiovascular health.

What We Cover

Why heart disease is still largely preventable yet so common
Cholesterol, ApoB, and the biggest nutrition myths patients face
Blood pressure as the most powerful but ignored risk factor
Soluble fibre, unsaturated fats, and gut health for heart protection
Menopause, metabolic changes, and shifting cardiovascular risk
Supplements vs food, and when medication still matters

A practical, evidence-based conversation on how to protect your heart for the long term.
