Talking Points

Recent interactions between the hosts and their guests.

Earwax Removers
Q: Are drops and oils actually effective at removing wax, or just softening it?
Drops and oils mainly soften the wax to make it easier for a health professional to remove; there is little evidence that any single drop type is superior, and they don't guarantee removal on their own.
Dough - Food
Q: How soon might cultivated meat reach price parity with traditional meat?
Owen suggests pilot facilities this year, with broader price parity as production scales and costs decrease in the near term.
Dough - Food
Q: What is the core problem cultivated meat could solve?
Owen highlights animal welfare and supply chain resilience, noting cultivated meat could reduce animal slaughter while providing a controllable, scalable protein source with less weather dependence.
Kefir
Q: Is there a risk of making Kefir at home?
The main risk relates to hygiene; ensure the milk is fresh and that you're using appropriate containers to manage gas production.
Kefir
Q: What does gut health mean in relation to Kefir?
Gut health can mean various things, including addressing symptoms of IBS, bloating, and constipation.
