Episode notes
Saturated Fat Triggers Body To Make Cholesterol
- Saturated fat stimulates the liver to make more cholesterol, raising blood LDL as if you ate cholesterol itself.
- Dietary and endogenously made cholesterol both end up in the terminal ileum affecting absorption and levels.
Use High Fiber To Lower Cholesterol
- Protect your gut by eating a whole-food, plant-based, high-fiber diet.
- That diet promotes bacteria that 'chop up' cholesterol before it raises blood levels.
Pick Smart Plant-Based Alternatives
- Choose plant-based alternatives over animal products when possible, but check for sodium and saturated oils.
- Vegan jerky lacks cholesterol and usually less saturated fat, but still inspect ingredients.
