Vegan Versus Ketogenic Diets

Imagine switching up your meals in a big way, ditching meat and dairy for a vegan lifestyle or diving deep into the world of low-carb keto. What happens to your body’s defences, your trusty immune system? A recent study published in Nature Medicine delves into this very question, comparing the impacts of these two popular diets.

Key findings:

  • Both vegan and keto diets cause noticeable shifts in the types of immune cells circulating in your blood.
  • Keto: Levels of specific cells involved in “adaptive immunity” (remembering past threats) like regulatory T cells and natural killers get a boost.
  • Vegan: Cells crucial for “innate immunity” (first-line defence) like activated T helper cells and natural killers see a rise.
  • Even the genes within these cells get jiggled around! Keto ramps up genes linked to T-cell activation, while vegan leans towards genes involved in other immune responses.

What does it mean?

This is the first research to show these distinct immune system responses to vegan and keto, potentially influencing our overall health. However, keep in mind:

  • The study was small, meaning more research is needed to solidify these findings.
  • Long-term effects weren’t explored,┬áso the lasting impact remains unclear.
