About this episode

Mikki Williden discusses the true factors that support immunity during winter, debunking common myths about fruit and vegetable intake.

In this Mini Mikkipedia episode, Mikki explores whether fruit and vegetables really “boost” immunity in the way we often hear during winter. While produce absolutely supports health, the clinical evidence suggests its immune benefits are more specific than the marketing implies, especially for those starting from a low intake. Mikki unpacks research on fruit and vegetable intake, vaccine response, vitamin C loss in stored produce, and why frozen vegetables deserve more respect. She then broadens the conversation into what actually moves the needle for immune resilience: adequate energy intake, sufficient protein, correcting true vitamin D and zinc deficiencies, and supporting gut health through fermented foods and dietary variety. The takeaway? Your immune system does not need hype; it needs enough fuel, enough protein, and the right nutrients. Tiny old-school truth bomb, really.
