BDA Conversations: From Confusion to Clarity: Phytosterols, Public Guidance, and the Portfolio Diet Example

The BDA is pleased to be offering another BDA Conversations webinar in 2026. 

Divergent recommendations on phytosterol use have led to inconsistent public messaging and uncertainty among clinicians and consumers. This talk will examine how aligning guidance with evidence from nutrition research and food-based guidance - illustrated by the Portfolio Diet, where phytosterols are one of several cholesterol-lowering components - can align evidence, policy, and practical advice to improve cardiovascular outcomes.
