Room by room
Every room has two layers: the measurable science of what's in the air, water and materials — and the felt art of how the space is arranged.
Where nourishment begins
Kitchen
What to fix
- Retire worn or scratched coated pans in favor of stainless, cast iron, or ceramic.
- Move food out of plastic containers and into glass or steel, especially anything warm or acidic.
- Turn the range hood on before the pan gets hot, not after the smoke shows up.
- Filter drinking water at the source — reverse osmosis with minerals added back is the cleanest setup.
How to arrange it
- Treat the cooktop as the heart of the home and keep every burner clean and usable.
- Stand where you can see the room while you cook; a small mirror behind the range solves a bad layout.
