Dr Andrea Glenn, a nutrition epidemiologist from NYU and Harvard, joins Simon Hill to examine the strongest evidence on plant-based nutrition. She unpacks new data on the plant-to-animal protein ratio and heart disease risk, explains how the Portfolio Diet can lower LDL as effectively as a statin, and debunks butter and tallow trends with recent mortality data. The conversation also defends the value of nutritional epidemiology and offers a practical roadmap based on the 2026 American Heart Association guidelines.

The Portfolio Diet Lowers LDL Like a Statin
The Portfolio Diet—a combination of plant sterols, soy protein, viscous fiber, and nuts—lowers LDL cholesterol to an extent comparable to a low-dose statin.
Low-carbohydrate diets are not monolithic; the health effects depend heavily on food quality—an avocado-rich low-carb diet is beneficial, while one heavy in butter and processed meats is associated with higher mortality.
Nutrition Epidemiology Is More Reliable Than Critics Claim11:00
Nutrition epidemiology, when conducted with repeated measures and rigorous sensitivity analyses, provides reliable evidence that informs dietary guidelines.
2026 AHA Dietary Guidance Emphasizes Plant-Forward Pattern
The 2026 American Heart Association guidelines emphasize a plant-forward dietary pattern, limiting saturated fat and tropical oils, and prioritize food-based recommendations over isolated nutrients.
